For example: surface manager (surface manager), media library (Media Libraries), 3D graphics processing library (eg: OpenGL ES), 2D graphics engine (eg: SGL), etc.

It can be understood that the components contained in the system framework layer and the runtime layer shown in FIG. 2 do not constitute a specific limitation on the electronic device 100 . In other embodiments of the present application, the electronic device 100 may include more or fewer components than shown in the figure, or combine certain components, or separate certain components, or arrange different components.

In this embodiment of the application, the electronic device can receive the user's setting operation of the external screen display mode, and the user's setting operation of the target display style displayed on the external screen. The status and type of the application program running in the foreground determine the display timing of the external screen. When the display timing of the external screen is reached, the target display style set by the user is displayed on the external screen, which can not only make reasonable use of external screen resources, but also satisfy the user's external Screen personalized display needs. In addition to displaying a fixed target style on the external screen, the electronic device can also flexibly switch the display style displayed on the external screen according to the process data of the application program running in the foreground, making the content displayed on the external screen more diverse.

It should be noted that the external screen display method involved in the embodiment of the present application can be triggered in an application program, or can be triggered in the external screen display interface of the system. For example, the external screen display method involved in the following embodiments of the present application can be triggered to execute in the application program that comes with the system, or can be triggered to execute in a third-party application program installed in the electronic device.

In the embodiment of the present application, descriptions are made from two perspectives: triggering the external screen display mode in the system external screen display interface and triggering the external screen display mode in the application program that comes with the system. Among them, when the external screen display mode is triggered in the external screen display interface of the system, it can be further divided into displaying the external screen in the do-not-disturb mode and the immersive mode. Among them, the Do Not Disturb mode is a special mode of the electronic device. In the Do Not Disturb mode, the electronic device can be set to reject calls or turn off incoming call ringtones, message ringtones, notification ringtones, etc., so as to avoid the electronic device from causing harm to the user. disturb. In this way, when the user is running an application program through the electronic device, if he does not want to be disturbed by the outside world, he can set the electronic device to the do not disturb mode, so that messages or incoming calls sent by other electronic devices will not disturb the user of the electronic device . At the same time, in the embodiment of the present application, when the electronic device is in the do-not-disturb mode, the do-not-disturb pattern is displayed on the external screen. By displaying the do-not-disturb pattern on the external screen, other people around can know that the user of the electronic device does not want others to disturb, thereby Effectively avoid the disturbance of people around you. It should be noted that the do-not-disturb mode can be turned on when there is a do-not-disturb demand, or a do-not-disturb time period can be preset by the user, and the electronic device enters the do-not-disturb mode when the do-not-disturb time period is reached.

The immersive mode is to determine that the application is continuously used by the user when the application is running in the foreground for the first preset period of time. At this time, the target display style is displayed on the external screen, which can prevent people around from disturbing the user of the electronic device. The electronic device can provide an interface for the user to set the target application program to be monitored. During use, the electronic device monitors the foreground running time of the target application program to be monitored, and the running time of a certain target application program in the foreground lasts for the first time. When the duration is preset, the target display style is displayed on the external screen to remind people around not to disturb the user of the electronic device.

The external screen display method in the embodiment of the present application is applied to a double-sided screen electronic device. An exemplary structural diagram of a double-sided screen electronic device is shown in Figures 3 to 4, and Figure 3 shows the screen of the electronic device in the unfolded state. A schematic diagram of the inner screen, and FIG. 4 is a schematic diagram of the outer screen of the electronic device when the screen is unfolded. Please refer to FIG. 4 , the right half of the outer screen of this exemplary double-sided screen electronic device is 401 which can be used as the display area of the outer screen, and the left half 402 is used as the rear shell of the device, and the rear shell is used for setting a camera and the like. In an actual implementation process, a part of the right half part 401 of the outer screen may also be used as the display area of the outer screen. Of course, it is not limited to this, the left and right parts of the outer screen of the double-sided screen electronic device can also be unequal, for example: the area occupied by the right half 401 is set to be larger than the area occupied by the left half 402, or the right half The area occupied by 401 is smaller than the area occupied by the left half 402 and so on. It is also possible to set both the left half and the right half of the external screen of the electronic device as a display screen. In this case, the camera on the external screen of the electronic device can be set as an off-screen structure, and the display area of the external screen can be flexibly set on the external screen. For example: set the right half as the external screen display area, set the left half as the external screen display area, set the right half partial area as the external screen display area, set the left half partial area as the external screen display area, set the external screen display The area is a strip running through the entire outer screen and so on.

In the following, the specific processes of the external screen display method in the do not disturb mode, the external screen display method in the immersive mode, and the external screen display method when the external screen display style is customized in the application program are described below in conjunction with specific embodiments.

The method for displaying the external screen in the do-not-disturb mode will be described below with reference to FIGS. 5 to 10 . In the embodiment of this application, the right half 401 of the outer screen of the electronic device is taken as an example of the outer screen display area, and the related operations of setting the outer screen display on the outer screen are taken as an example for illustration. It should be noted that the operations related to the external screen display are not limited to setting when the screen of the electronic device is in a folded state, but can also be set on the internal screen after the screen of the electronic device is unfolded, which is not specifically limited in this embodiment of the application .

Exemplarily, when the user sets the external screen display, the external screen display setting interface 501 as shown in FIG. , an immersive mode control 6013 and a smart power saving switch 5014 . Wherein, the external screen display switch 5011 is used to control whether to enable the external screen display function. When the external screen display switch 5011 is turned on, the external screen display function is turned on. Correspondingly, when the external screen display switch 5011 is turned off, the external screen display function is turned off. 5011 open is a prerequisite for external screen display. The do not disturb mode control 5012 is the entrance of the external screen display in the do not disturb mode, through which the relevant setting interface of the external screen display in the do not disturb mode can be entered. The immersive mode control 5103 is the entrance of the external screen display in the immersive mode, through which the relevant setting interface of the external screen display in the immersive mode can be entered. The smart power-saving switch 5014 is used to control whether to enable the smart power-saving function. After the smart power-saving function is turned on, the display brightness of the external screen will automatically change with the light environment. It is in the power-saving mode or the remaining power of the electronic device is less than a preset percentage such as 10%. , the external screen does not display. After the intelligent power-saving function is turned off, the display brightness of the external screen will not automatically change with the light environment, and the display on the external screen will not stop displaying because the remaining power of the electronic device is less than the preset percentage or the electronic device is in power-saving mode. On the one hand, turning on the intelligent power saving function can save the power consumption of the external screen display and prolong the battery life of the electronic device; on the other hand, since the brightness of the external screen display automatically changes with the light environment, for example, when the external light is bright, the display brightness will be adjusted. Dark, can improve the display effect of the external screen. Another example: when the external light is dark, the display brightness can be dimmed to save the power consumption of the external display.

Exemplarily, as shown in FIG. 5, after receiving the user's touch operation on the do not disturb mode control 5012, such as clicking, pressing and other operations, the display style setting interface 601 in the do not disturb mode as shown in FIG. 6 is displayed , the display style setting interface 601 in the Do Not Disturb mode includes the first prompt information 6011 such as "When the mobile phone is in the Do Not Disturb state, an external screen display appears, you can set it in Settings>Sound and Vibration> Do Not Disturb, and enable Do Not Disturb Set the time period", the first prompt message 6011 is used to prompt the user to set the do not disturb time period according to the specified path. The display style setting interface 601 in the do not disturb mode also includes a plurality of system preset display styles 6012 and a display style adding entry 6013 . The user can choose one of the display styles preset by the system as the target display style output on the external screen in the do-not-disturb mode. The user can also select the display style to add entry 6013, select pictures or videos from the photo album as the target display style for external screen output, or call the camera to take pictures or videos as the target display style for external screen output. In this embodiment, the user selects the system-preset "do not disturb" display style as the target display style as an example for subsequent description.

After the user selects the target display style displayed on the external screen in the do-not-disturb mode, execute the do-not-disturb enabling process. FIGS. 7a-7b are schematic interface diagrams of an exemplarily showing the process of enabling Do Not Disturb. The user can open the sound and vibration setting interface 701 shown in FIG. It may include but not limited to operations such as single click, double click, or long press. After the user touches the "Do Not Disturb" control 7011 in the interface, the trigger system enters the Do Not Disturb setting interface 702 shown in FIG. The switch 7021 is used to control whether to turn on Do Not Disturb immediately, and if it is turned on, the electronic device immediately enters the Do Not Disturb state; for example, if the user clicks to turn on the switch 7021, the electronic device enters the Do Not Disturb state in response to the received user operation. Timing on switch 7022 is used to control whether to turn on the timing do not disturb. After the timing on switch is turned on, the user can set the do not disturb time period in the do not disturb opening period setting item 7023. When the immediately on switch 7021 is turned off, the time period set by the user can be reached. After the do not disturb time period, the electronic device enters the do not disturb state. After the timing switch 7022 is turned on, a do-not-disturb time period can be displayed by default in the system, and the user can manually modify the do-not-disturb time period, for example, modify it to 15:00-17:00 as shown in Figure 7b. In this example, the immediate start switch 7021 is not turned on, and the do-not-disturb time period is set to 15:00-17:00 as an example for illustration.

Continuing with the above example, Fig. 8 is a schematic diagram of the external screen interface in the do not disturb mode. In this mode, the target display style displayed on the external screen is "Do Not Disturb". After the system time reaches 15:00, the target display style "Do Not Disturb" will be directly displayed on the external screen. In this specific scenario where the target display style is displayed on the external screen in the do-not-disturb mode, the timing of the external screen display and the displayed target display style are not affected by the application program running on the foreground of the electronic device or the specific content displayed on the internal screen of the electronic device. It should be noted that, when the target display style is displayed on the external screen during the do-not-disturb time period, it can be displayed statically or dynamically. When displayed statically, it can be continuously displayed or intermittently displayed at preset intervals. The dynamic display style can be set by those skilled in the art according to actual needs, which is not specifically limited in this embodiment of the present application. For example: in the display area of the external screen, it can be scrolled horizontally, slid along the diagonal of the display area of the external screen, etc.

In the do-not-disturb time period, the target display style can be displayed on the external screen, which can display the current state and avoid disturbing others.

In addition to the above-mentioned DND mode scene where the target display style is displayed on the external screen when the DND time period is set, the system can also automatically identify the time period corresponding to the conference schedule event based on the conference schedule event created by the user, and set it in the conference schedule event Under the corresponding time period, the display style matching the meeting schedule event is displayed on the external screen. The related process of external screen display in this specific scenario will be described below with reference to FIG. 9 to FIG. 10 .

Exemplarily, FIGS. 9a to 9b are schematic diagrams of the interface for creating a meeting schedule event, wherein FIG. 9a is a schematic diagram of the new schedule interface, and the new schedule interface 901 includes: title 9011, location 9012, start time 9013 and End time 9014 four setting items, the user can enter the corresponding content under each setting item, for example: input the conference title such as "xx meeting" under the title setting item, enter the meeting location such as "company" under the location setting item, and enter Enter the meeting start time under the start time setting item, such as "July 28th at 10:00 am", and enter the meeting end time under the end time setting item, such as "July 28th at 11:00 am". After completing the settings of the above-mentioned setting items, the user can click on the generating option 9015 (for example, "√" in the figure) to trigger the system to generate conference schedule events according to the user's settings. After the conference schedule event is generated, the generated conference schedule event 9021 and the start time and end time of the conference schedule event are displayed on the calendar interface 902 shown in FIG. 9b. The system monitors the generated meeting schedule events, and starts to display the display style corresponding to the meeting schedule events in the display area of the external screen after detecting that the meeting schedule event start time point has been reached.

Exemplarily, Figs. 10a-10b are schematic diagrams of the interfaces of the inner screen and the outer screen during the meeting process, and Fig. 10a exemplarily shows that the meeting interface 1001 is displayed on the inner screen of the electronic device after the meeting schedule event starts. Simultaneously, the display style "in the meeting" matching the meeting schedule event is displayed on the external screen 1002 of the electronic device.

It should be noted that, FIG. 10a only takes a video conference as an example for illustration, and in actual implementation, the conference schedule event is not limited to a video conference but may also be a voice conference. And when the external screen displays the display style that matches the conference schedule event, it is not limited to displaying the conference interface on the internal screen. After reaching the start time of the conference schedule event, regardless of whether the conference interface is displayed on the internal screen, it will be displayed on the external screen. Displays the display style for meeting schedule event matches. This method of displaying the matching display style of the meeting schedule event on the external screen, on the one hand, can remind the user that the created meeting schedule time event has expired, so as to prevent the user from missing the meeting; on the other hand, the user displays "meeting In" to remind others that the user is currently in a meeting to avoid interruptions from others.

It should be noted that in Figures 9 to 10, the system monitors the meeting schedule events created by the user in the calendar application program, and when the opening time of the meeting schedule event is reached, the display style "meeting" matching the meeting schedule event is displayed on the external screen "in" as an example. In the actual implementation process, it is not limited to monitoring the conference schedule events created by users, but also other types of schedule events created by users, such as: business trip events, video learning schedule events, offline conference schedule events, etc., the Each type of event corresponds to a corresponding start time. When the system detects that the scheduled event created by the user reaches the start time, it will display a display style that matches the scheduled event on the external screen. In an optional embodiment, the schedule event monitoring can also be combined with the do-not-disturb mode. The user can first preset the do-not-disturb time period. In the case of a time period, when the schedule event starts, the electronic device will turn on the rejection of calls or turn off the do-not-disturb restrictions such as incoming call ringtones, message ringtones, and notification ringtones, so as to avoid other electronic devices from interfering with the user's schedule events. At the same time, the external screen displays The display style that matches the schedule event, through the style displayed on the external screen, other people around can know that the user of the electronic device does not want others to disturb, so as to effectively avoid the disturbance of people around.

It should be noted that, in addition to the above-mentioned scenario of monitoring the calendar events created by the user, and displaying the style "in a meeting" on the external screen after the monitoring reaches the start time of the calendar event, the electronic device can also notify the user that the user is invited And the accepted meeting schedule events are monitored, and the style "in meeting" is displayed on the external screen after the monitoring reaches the opening time of the meeting log event.

In the following, in combination with the external screen display software architecture Fig. 11 , an electronic device displays the target display style "in a meeting" on the external screen according to the conference schedule event created by the user as an example.

As shown in Figure 11, the software architecture includes an application program layer, an application program architecture layer and a kernel layer, wherein the application program layer includes a calendar 1100, a meeting 1101, an off-screen display application program 1102, and the application program architecture layer includes a window management device 1103, view system 1104 and business scene recognition module 1105, the kernel layer includes an external screen display driver 1106 and an internal screen display driver 1107. A polling mechanism may be set in the business scenario identification module 1105 for polling whether a schedule event is created in the calendar 1100, and the schedule event includes: a meeting schedule event. The external screen display method in this scenario includes the following steps:

S1: The business scenario identification module 1105 detects the conference schedule event created in the calendar 1100, and acquires relevant information of the created conference schedule event.

The business scenario identification module 1105 may poll the calendar 1100 through an internally configured polling mechanism to detect whether a meeting schedule event is created in the calendar 1100 .

When a user pre-creates a meeting schedule event, the creation can be completed in the calendar application. The interactive interface for the user to create a meeting schedule event in the calendar is shown in FIGS. 9a-9b. Wherein, the meeting schedule event includes a start time and an end time.

S2: When the business scene recognition module 1105 recognizes that the meeting schedule event starts, it acquires the start time and end time of the meeting schedule event, and when the monitoring reaches the start time of the meeting schedule event, it sends the "in meeting" display style corresponding to the off-screen display application 1102 information on the first interface.

Through the information on the first interface, the display style of "in a meeting" can be displayed on the external screen.

The "in-meeting" display style can be the display style associated with the meeting schedule event by the user in advance, or it can be automatically matched by the system from the display style preset by the system according to the type of the monitored schedule event. For example, if the monitored schedule event is a meeting schedule event, then the display style "in meeting" will be automatically matched from the display styles preset by the system.

The business scene recognition module 1105 can carry the AOD interface information in the instruction, notification or request and send it to the off-screen display application 1102, so that the off-screen display application 1102

S3: Screen-off display The application program 1102 sends the first interface information to the window manager 1103 .

The first interface information may be carried in an instruction, notification or request and sent to the window manager 1103 .

S4: The window manager 1103 sends a first notification to the view system 1104 .

The first notification is used to notify the view system 1104 to display the second interface information on the second display screen 192 . The second notification may carry the second interface information and the identification information of the second display screen 192 .

S5: The view system 1104 sends a calling command to the external screen display driver 1106 .

After analyzing the first notification sent by the window manager 1103, the view system 1104 determines to call the external screen display driver 1106 according to the identification information of the second display screen 192, and therefore sends a call-up instruction to the external screen display driver 1106, wherein calling The start command may carry the first interface information.

After the external screen display driver 1106 receives the call-up command, it analyzes and obtains the first interface information, drives the second display screen 192, and sends the first interface information to the second display screen 192 for display. The display style of "in meeting" corresponding to the information on the first interface will be displayed.

It should be noted that the "in meeting" on the second display screen 192 may continue to be displayed until the "in meeting" is replaced after receiving an instruction to cancel the display or receiving other interface information sent by the external screen display driver 1106 . "In meeting" on the second display screen 192 may also be displayed once at preset time intervals. After the business scene identification module 1105 recognizes that the meeting schedule event is over, it can send an instruction to cancel displaying the first interface information to the off-screen display application program 1102, and the off-screen display application program 1102 sends the external screen to stop displaying the first interface to the window manager 1103. Information notification, the window manager 1103 sends a notification to the view system 1104 that the external screen stops displaying the first interface information, and the view system 1104 sends a notification to the external screen display driver 1106 that the external screen stops displaying the second interface information, and finally the second display screen In 192, the display style of "in-meeting" is cancelled.

S6: When the meeting schedule event start time is reached, start the meeting in the meeting 1101, and the meeting 1101 sends the second interface information to the window manager 1103;

Wherein, the meeting 1101 is a meeting application program. In the actual implementation process, when the start time of the meeting schedule event is reached, the user can manually open the meeting 1101 for the meeting, or the system can automatically open the meeting 1101 for the meeting.

The second interface information is the interface information of the application program displayed on the inner screen. The conference 1101 may send the interface information of the conference application displayed on the internal screen to the window manager 1103 in an instruction or notification message.

S7: The window manager 1103 sends a second notification to the view system 1104 .

The second notification is used to notify the view system 1104 to display the second interface information on the first display screen 194 . The second notification may carry the second interface information and the identification information of the first display screen 194 .

It should be noted that, the above is only an example of sending a notification from the window manager 1103 to the view system 1104. In the actual implementation process, the window manager 1103 may also generate an The instruction or request of the identification information performs data interaction with the view system 1104 in the form of instruction or request.

S8: The view system 1104 sends a calling command to the internal screen display driver 1107 .

Do not disturb mode control 6012 , immersive mode control 6013 and smart power saving switch 6014 . Immersive mode control 6103 is the entrance of the external screen display in the immersive mode, through which the relevant setting interface of the external screen display in the immersive mode can be entered. For the functions of other controls in the external screen display setting interface, please refer to the related description of FIG. 6 in the aforementioned scenario embodiment, and details will not be repeated here. Exemplarily, as shown in FIG. 12, after receiving the user's touch operation on the immersive mode control 12011, such as clicking, pressing, etc., jump to the display style setting interface 1301 in the immersive mode as shown in FIG. 13 , the display style setting interface 1301 in the immersive mode includes an application list, and the application list includes at least one application icon, an application icon addition control 13011 and an application icon deletion control 13012, wherein the application icon addition control 13011 is for the user to add Application icon, for example: after the user clicks the application icon adding control 13011, he can select at least one application icon to add to the application list shown in FIG. 13 . The application icon deletion control 13012 is for the user to delete the application icon, for example: the user selects the application A icon and then clicks the application icon addition control 13012, and the application A icon can be deleted from the application list. It should be noted that, when adding application program icons to the application list for a single time, one or more application program icons may be added. One or more application icons can also be removed when removing application icons from the application list at a time. When deleting multiple application icons at the same time, you can select the application icons to be deleted from the application list in turn, and then click the application icon deletion control 13012 to trigger the system to delete the selected application icons from the application list. The applications in the application list can be the application icons automatically filtered by the system based on the user's historical usage habits, or the application icons manually added during the user's historical usage. The application icons in the application list can include but are not limited to: games application icons, video application icons, social application icons or reading application icons, etc. When the running state of the application corresponding to the application icon in the application list satisfies the conditions of the immersive mode, the target display style in the immersive mode set by the user is displayed on the external screen.

The display style setting interface 1301 in the immersive mode also includes a second prompt message 13013 such as "when the device is used continuously for more than 5 minutes, an external display will appear", the second prompt message 13013 is used to prompt the user to change the immersive mode. It should be noted that the 5 minutes shown in the second prompt message 13013 in FIG. 13 is only an exemplary value, and this value can also be called the first preset duration, which can be flexibly set by those skilled in the art or users. There is no specific restriction on this, for example: set to 0 minutes, 8 minutes or 10 minutes, etc. When the first preset duration is set to 0, after the application program corresponding to the application program icon in the application list is started, the target display style set by the user is immediately displayed on the external screen.

The display style setting interface 1301 in the immersive mode also includes a plurality of system preset display styles 13014 and a display style adding entry 13015 . Users can choose one of the display styles preset by the system as the target display style output on the external screen in immersive mode. The user can also select the display style to add entry 13015, select pictures or videos from the photo album as the target display style for external screen output, or call the camera to take pictures or videos as the target display style for external screen output. In this embodiment, follow-up descriptions will be made by taking the user's selection of the system-preset "do not disturb" display style as the target display style as an example. Continuing with the above example, after the user completes the application list and the target display style in immersive mode "Do Not Disturb for Focused Work", when any application in the application list is opened for more than 5 minutes, the system determines that the application running in the foreground is in the In the immersive mode, the external screen displays "Focus on Office Do Not Disturb". Among them, the schematic diagram of the external screen interface in the immersive mode is shown in Figure 14. This external screen display method can display a do-not-disturb prompt on the external screen when the user is immersed in applications such as watching movies, reading, video conferencing, or games, so as to avoid others from disturbing the user.

In an optional embodiment, the electronic device can flexibly control whether the external screen displays the target display style in the immersive mode according to the distance between the electronic device and the user's preset location. For example: during the user’s call through the electronic device, it is detected that the distance between the electronic device and the user’s ear is less than the preset distance, so even if the electronic device is determined to be in the immersive mode, the target display style in the immersive mode will not be displayed on the external screen, The external screen will turn off the screen, which can save the power consumption of the external screen display. In an optional embodiment, when the light signal cannot be detected by the external screen of the electronic device, it means that the electronic device may be placed on a table or a stand, and the external screen is invisible to others. At this time, the external screen will be off. Stopping the display can save the power consumption of the external screen display.

In addition to setting a unified target display style for each application icon in the application list as shown in Figure 13, you can also set the display style in immersive mode for the application icon separately. Select the display style of "watching a movie" in the display style set, and at this time, the corresponding relationship between the application B icon and the display style of "watching a movie" is successfully established. The interface information of application B running in the foreground is played on the internal screen of the electronic device, and the target display style "viewing movie" is directly displayed on the external screen after application B runs for 5 minutes. By repeating the process of establishing the correspondence between application program icons and display styles, the corresponding display styles can be set for each application program icon in the application program list. In the actual implementation process, it is also possible to only set corresponding display styles for some application program icons in the application list, while other application program icons without display styles may correspond to a default display style of the system.

It should be noted that when the target display style is displayed on the external screen in immersive mode, it can be displayed statically or dynamically. When displayed statically, it can be continuously displayed or intermittently displayed at preset intervals. The dynamic display style can be set by those skilled in the art according to actual needs, which is not specifically limited in this embodiment of the application. For example: in the display area of the external screen, it can be scrolled horizontally, slid along the diagonal of the display area of the external screen, etc.

In an optional implementation, when setting the display style in the immersive mode for the application icon in the application list separately, as shown in Figure 13, the user can choose one of the display styles preset by the system In addition to the target display style output on the external screen in immersive mode, the user can also select the display style addition entry 13015, which triggers the system to display the display style addition path setting interface 1502 shown in Figure 15a. The display style addition path setting interface includes display Style adding path menu 15021, display style adding path menu 15021 includes: the first adding path option such as adding option 150121 from the photo album, the second adding path option such as enabling camera shooting adding option 150122 and the third option such as purchased in the application Style added option 150123. Among them, by selecting the first add path option 150121, the user can select a picture or video from the photo album as the target display style of the external screen output. By selecting the second add path option 150122, the user can call the camera to take pictures or videos as the target display style of the external screen output. By selecting the third adding path option 150123, the user can select a display style from the purchased styles in application C as the target display style for external screen output. Users can choose any adding option from the display style adding path menu according to actual needs. In this embodiment of the application, the user manually selects the purchased style addition option 150123 as an example for illustration. It should be noted that, Fig. 15a exemplarily shows that the application list contains multiple application program icons, and the user indirectly selects an application program by selecting an application program icon. In the actual implementation process, it is not limited to this, and the application program name may also be displayed in the application list, and the user selects the application program by selecting the application program name.

After the system detects that the user selects the purchased style addition option 150123, it jumps to the purchased style selection interface 1503 shown in FIG. The switch 15031 for external screen display immediately after a specific item, the user can manually select at least one of multiple purchased display styles as the target display style for external screen display when application C is in immersive mode. in. After the switch 15031 is turned on and the application program is running, after the user purchases a specific item, the purchased specific item is immediately displayed on the external screen of the electronic device as the target display style. In the embodiment of the present application, the user selects the first display style 15032 such as the smiley face style and the second display style 15033 such as the crown style as an example for illustration. It should be noted that the switch 15031 may not be set in the purchased style selection interface 1503. During the running of the application program C, the application program C may decide whether to display the corresponding display style on the external screen immediately after the user purchases a specific item.

Continuing from Figure 15b, after completing the setting of the target display style of the external screen display in the immersive mode of the application program C, after the application program C runs for the first preset time and enters the immersive mode for 5 minutes, the internal screen and the external screen display The schematic diagram of the interface is shown in Figure 16, wherein, Figure 16(a) is a schematic diagram of the internal screen interface in the immersive mode, and Figure 16b is a schematic diagram of the external screen interface in the immersive mode, as shown in Figure 16, the interface of application C Display on the inner screen, when the purchased target display style is displayed in application C and selected by the user, the same display style will be displayed synchronously on the outer screen. For example: Application C is a game application. When continuous critical strikes occur during the game, the crown style 15033 shown in Figure 16(a) is displayed. Since the crown style 15033 is preset by the user in the immersive mode of Application C This is the target display style displayed on the external screen, so the crown style 15033 is displayed synchronously on the external screen interface shown in Figure 16(b). Similarly, when the smiley face pattern 15032 appears in the display interface of the internal screen, the external screen displays the smiley face pattern 15032 synchronously.

It should be noted that FIG. 16 only exemplarily enumerates a manner of synchronously displaying the same display style on the external screen when the target display style preset by the user is displayed on the internal screen interface. In the actual implementation process, the running time of the application program C running in the foreground can reach a first preset duration, such as 5 minutes, and the target display style preset by the user for the application program C is displayed on the external screen. It should be noted that, in this case, if the preset target display styles of the user are two or more display styles, such as the smiley face style 15032 and the crown style 15033 shown in FIG. The target display style may also display preset target display styles at the same time, and the specific display mode is not limited in this embodiment of the present application.

The method of setting a personalized display style for the application in the immersive mode provided in this optional embodiment, on the one hand, can meet the user's personalized display requirements, and on the other hand, can improve the fun of the external screen display.

In the following, the external screen display method will be described by taking the scene where the video application is in the immersive mode when watching a movie through the video application as an example in combination with the external screen display software architecture shown in FIG. 17 .

As shown in Figure 17, the software architecture includes an application layer, an application architecture layer, and a kernel layer, wherein the application layer includes a video application 1701, an off-screen display application 1702, and the application architecture layer includes a window manager. 1704 , the view system 1705 and the business scene recognition module 1706 , the kernel layer includes an external screen display driver 1707 and an internal screen display driver 1708 . Wherein, the business scene identification module 1706 is provided with a polling mechanism, which can identify the application program running in the foreground, and the continuous running time of the application program running in the foreground can be identified through multiple polling.

The external screen display method based on the software architecture shown in Figure 17 comprises the following steps:

S1: After the user starts the video application program 1701 to watch a movie, the video application program 1701 sends the first interface information to the window manager 1704 .

Wherein, the first interface information is the interface information of the video application program, including but not limited to: video frame, viewing duration, and the like. The first interface information may be carried in the instruction, notification or request information and sent to the window manager 1704 . The user enables the immersive mode in the external screen display setting interface, and can set the target applications to be monitored in the application list. Each application corresponds to an application icon, and the application corresponding to the application icon contained in the application list can be used as the application to be monitored. target application. In this example, the video application 1701 is included in the target application set by the user, and the user pre-selects the display style of "watching a movie" for the video application 1701 as an example for illustration.

S2: The window manager 1704 will send a first notification to the view system 1705 .

Wherein, the first notification is used to notify the view system 1705 to display the first interface information on the first display screen 194 . The first notification may carry the first interface information and the identification information of the first display screen 194 .

It should be noted that, the above is only an example of sending a notification from the window manager 1704 to the view system 1705. In the actual implementation process, the window manager 1704 may also generate an Instructions or requests for identification information perform data interaction with the view system 1705 in the form of instructions or requests.

S3: The view system 1705 sends a calling command to the internal screen display driver 1707 .

After analyzing the first notification sent by the window manager 1704, the view system 1705 determines to call the internal screen display driver 1707 according to the identification information of the first display screen 194, and therefore sends a call-up instruction to the internal screen display driver 1707, wherein calling The start command may carry the first interface information.

The internal screen display driver 1707 drives the first display screen 194 in response to the calling instruction, and displays the first interface information, that is, the interface information of the video application program, on the first display screen 194 .

S4: The business scene identification module 1706 invokes the polling mechanism to monitor the status of the video application.

The business scene recognition module 1706 detects that the video application 1701 is running through a polling mechanism, and monitors the running time of the video application 1701. When it detects that the running time of the video application 1701 exceeds the first preset time, for example, 5 minutes, Determine the mechanism that triggers the external screen display.

S5: The business scene identification module 1906 sends the second interface information to the off-screen display application program 1702 .

Wherein, the second interface information may be sent to the off-screen display application program 1702 carried in an instruction, a notification, or a request. When the business scene recognition module 1906 recognizes that the running time of the video application 1701 exceeds the first preset duration, it determines that the display style corresponding to the video application 1701 preset by the user is "watching a movie", and sets "watching a movie" to The information of this display style is sent to the off-screen display application program 1702 as the second interface information.

S6: The off-screen display application program 1702 sends the second interface information to the window manager 1704 .

S7: The window manager 1704 sends a second notification to the view system 1705 .

The second notification is used to notify the view system 1705 to display the second interface information on the second display screen 192 . The second notification may carry the second interface information and the identification information of the second display screen 192 .

S8: The view system 1705 sends a calling command to the external screen display driver 1708 .

After the view system 1705 parses the second notification sent by the window manager 1704, it determines to call the external display driver 1708 according to the identification information of the second display screen 192, so it sends a call command to the external display driver 1708, wherein the calling The start command may carry the second interface information.

The external screen display driver 1708 drives the second display screen 192, that is, the external screen, in response to the call-up instruction, and displays the second interface information on the second display screen 192, that is, the display style of "viewing a movie".

Through the external screen display process executed by the above-mentioned software architecture, when it is detected that the user’s use of the video application program reaches the first preset duration, “watching” will be displayed on the external screen, that is, the second display screen, which can prevent people around from disturbing the video. Device users watch movies.

It should be noted that S1-S3 and S4-S8 are executed in parallel, and there is no sequence between them.

The above described the method of displaying the external screen in the do not disturb mode and the method of displaying the external screen in the immersive mode in detail respectively. The following describes the customizing of the external screen display style in the application program in the embodiment of the present application with reference to FIG. 18 to FIG. 20 The specific process of the external screen display method will be described. In the embodiment of the present application, the right half of the outer screen of the electronic device is still taken as an example for illustration.

The following describes how to customize the display style of the external screen in the phone application that comes with the electronic device system as an example. Exemplarily, as shown in FIG. 18(a), the phone application main interface 1803 includes an add option 18031. When the user pre-applies a custom external screen display style to the phone, the user performs a touch operation on the add option 18031, such as clicking or long According to the operation etc., the trigger system displays the custom style setting interface as shown in Fig. 18(b). Among them, the add option 18031 is an entry for setting the external screen display, through which the user can trigger the system to display the custom style setting interface 18031 . The custom style setting interface 1801 includes system preset styles such as "busy game" 18011, "focus on office and do not disturb" 18012, added styles in the application such as family portrait pictures 18013 and preset graphics 18014, custom added style options 18015 and Smart power saving switch 18016.

In FIG. 18( b ), two system preset styles and styles added in the application are listed for example, and the system preset styles are not limited thereto. The style added in the application can be the display style added when the user used the phone application in history, for example: before talking with friend a in the history of use, add a group photo with friend a as a custom style, and open the phone application next time After the custom setting interface 1801 of , the added style of the application in the custom setting interface 1801 will include the group photo, and the phone application will automatically establish an association between the group photo and a friend. When using the phone application later, when the user sets the group photo as the target display style displayed on the external screen, the group photo can be displayed on the external screen when the user is talking with friend a. Or no matter whether the user is talking with a friend or not, as long as it is detected that the user is using the phone application to talk, the group photo will be displayed on the external screen. The custom style option 18013 is for the user to add a custom style, for example: the user can also select the custom style option 18013, and select a picture or video from the album as a custom display style; the user can also call the camera to take pictures or videos as Custom display style, wherein, the custom display style added by the user through the custom add style option will be used as the target display style of the external screen output.

An optional way to customize the display style by customizing the adding style option can be: the user clicks on the custom adding style option 18013, triggering the system to display the custom display style adding path, including but not limited to: adding options from the photo album and Turn on the camera capture add option. Among them, the user can select a picture or video from the album as a custom display style by selecting the option to add from the album. The user can also further call the camera to take pictures or videos as a personalized display style by selecting the option to enable the addition of camera shooting.

The smart power saving switch 18016 is used to control whether to enable the smart power saving function. After the smart power saving function is turned on, the display brightness of the external screen will automatically change with the light environment. It is in the power saving mode or the remaining power of the electronic device is less than a preset percentage such as 10%. , the external screen does not display. After the intelligent power-saving function is turned off, the display brightness of the external screen will not automatically change with the light environment, and the display on the external screen will not stop displaying because the remaining power of the electronic device is less than the preset percentage or the electronic device is in power-saving mode. On the one hand, turning on the intelligent power saving function can save the power consumption of the external screen display and prolong the battery life of the electronic device; on the other hand, since the brightness of the external screen display automatically changes with the light environment, for example, when the external light is bright, the display brightness will be adjusted. Dark, can improve the display effect of the external screen.

After selecting the target display style in the custom style setting interface, the user can manually click any selected target display style such as 18013. After the system receives the user's click operation on the target display style 18013, it will display as shown in Figure 19 The application style preview interface 1802, the application style preview interface 1802 includes the preview thumbnails of the target display styles selected by the user, such as the family portrait style 18013, the preview thumbnails of the display styles not selected by the user, such as 18014, and the application button 18017 , and the preview image of the family portrait style 18013, the user can manually switch the display style selected by the user or the display style not selected by the user to preview. After the user determines to apply a certain display style such as the family portrait style 18013, he can click the apply button 18017.

Continuing to refer to FIG. 18( b ), in the embodiment of the present application, the family portrait picture 18013 that has been added in the application selected by the user is taken as an example for illustration. After completing the custom display style setting of the phone application, when making a call through the electronic device, as shown in the schematic diagram of the external screen display interface shown in Figure 20, the user-defined display style family portrait is displayed on the external screen of the electronic device Image 18013. Wherein, the size of the family portrait picture 18013 displayed on the external screen can be adapted to the size of the external screen, or can be the original size.

It should be noted that the above is only an example of a user-defined display style. In the actual implementation process, the user can select two or more display styles in the custom setting interface 1801 as the target of the external screen display. When displaying the style, the system can determine the matching display style according to the current interface content of the phone application and output it on the external screen. For example: based on the user's historical operations, the relationship between the family portrait picture 18013 and the phone number of the user's family has been established in the phone application, and the relationship between the phone number of the user's company leader and "Do Not Disturb" 18012, the user selects the family portrait When the two display styles of picture 18013 and "do not disturb at work" 18012, when the user talks with his family, the family portrait picture 18013 can be displayed on the external screen of the electronic device; when the user talks with the leader, the external screen of the electronic device can display "Do Not Disturb" 18012 is displayed.

This method of setting an interface in the application program interface for the user to customize the display style of the external screen, on the one hand, can enrich the content of the external screen style; on the other hand, can meet the personalized display requirements of the user.

It should be noted that the above is only an example of customizing the display style of the external screen in the phone application. screen display style. Not only that, users can also customize the external screen display style in third-party applications such as video applications, social applications, or game applications. For game applications, the display style added in the application can be the display style corresponding to the feature items purchased by the user in the game application, or it can be the user's custom-added style options when using the game application in the past The added display style. Not only that, for the game application, it can also be preset by the user, and the display style of the purchased specific item will be displayed on the external screen immediately when the specific item is purchased, so that when the user purchases the specific item during the game, although the user does not The display style corresponding to the specific item is pre-selected as the target display style displayed on the external screen, and the purchased display style of the specific item will still be displayed immediately on the external screen.

The method for displaying the external screen when customizing the display style of the external screen in the above-mentioned phone application will be described below in conjunction with the external screen display software architecture shown in FIG. 21 .

Exemplarily, as shown in Figure 21, the software architecture includes an application layer, an application architecture layer, a kernel layer, and hardware, wherein the application layer includes a phone application 2101, an off-screen display application 2102, and an application architecture layer The window manager 2104 and the view system 2105 are included in the kernel layer, and the inner screen display driver 2106 and the outer screen display driver 2107 are included in the kernel layer.

Based on the software architecture shown in Figure 21, the external screen display method performed includes the following steps:

S1: After the phone 2101 is turned on, send the first interface information to the window manager 2104.

The following describes the target display style displayed on the external screen when the user selects the family portrait picture 18013 as the phone application through the user interface settings shown in FIGS. 18 to 19 as an example.

Wherein, phone 2101 refers to a phone application program, and the first interface information is interface information of the phone application program. The interface information may include, but is not limited to: contact information for establishing a call connection, call duration, and the like.

S2: The window manager 2104 sends a first notification to the view system 2105 .

Wherein, the first notification is used to notify the view system 2105 to display the first interface information on the first display screen 194 . The first notification may carry the first interface information and the identification information of the first display screen 194 .

It should be noted that the above is only an example of sending a notification from the window manager 2104 to the view system 2105. In the actual implementation process, the window manager 2104 may also generate The instruction or request of the identification information performs data interaction with the view system 2105 in the form of instruction or request.

S3: The view system 2105 sends a calling command to the internal screen display driver 2106 .

After analyzing the first notification sent by the window manager 2104, the view system 2105 determines to call the internal screen display driver 2106 according to the identification information of the first display screen 194, and therefore sends a call-up instruction to the internal screen display driver 2106, wherein the calling The start command may carry the first interface information.

The internal screen display driver 2106 drives the first display screen 194 in response to the calling instruction, and displays the first interface information, that is, the interface information of the phone application program, on the first display screen 194 .

S4: When the phone 2101 detects that the duration of the call exceeds 5 minutes, send the second interface information to the off-screen display application program 2102 .

Wherein, the second interface information is the image information of the family portrait picture 21013 display style. The second interface information may be carried in the notification, request or instruction and sent to the off-screen display application 2102.

When it is determined that the duration of the call exceeds 5 minutes, the phone 2101 determines that the user's pre-selected target display style needs to be displayed on the external screen, and the user's pre-selected target display style can be found by filtering the status of each display style.
