It should be noted that the control method provided in the embodiments of the present application may be applied to a control device, or an electronic device integrated with the control device. Among them, the electronic apparatus may include an apparatus having a display device such as a display screen, for example, a Personal Computer (PC), a notebook Computer, a Personal Digital Assistant (PDA), a Portable Multimedia Player (PMP), a Smart Phone (Smart Phone), a television, and the like. In the embodiment of the present application, a specific implementation of the embodiment of the present application is described by taking AIO as an example.

It should be further noted that the control method provided in the embodiment of the present application may be applied to displaying a plurality of content sources in a plurality of different display areas of an electronic device, respectively, when there are a plurality of content source inputs in the electronic device. For example, a display screen of the electronic device is divided into a plurality of display areas, which respectively correspond to different content sources, and at this time, the resolution input by the content sources needs to be adjusted to achieve the best picture display effect.

Therefore, in response to a display output instruction for outputting at least two content sources, the embodiment of the present application obtains display identification information of at least two display areas corresponding to the at least two content sources. The content source may include, among other things, a video stream signal, a display screen signal, etc. from the electronic device itself or other external devices. In addition, the display identification information may be EDID information, and the display identification information may carry resolution information that needs to be modified, so that the resolution input by the content source may be correctly modified by the display identification information.

In some embodiments, obtaining display identification information for at least two display regions corresponding to at least two content sources may include:

dividing a display output area of the display screen into at least two display areas in response to the split screen triggering operation;

and obtaining the display identification information of each display area at least based on the split screen triggering operation.

It should be noted that, when obtaining the display identifier information, the display output area of the display screen may be divided into at least two display areas in response to obtaining the split-screen trigger operation, and the display identifier information corresponding to each display area may be obtained based on the split-screen trigger operation. The screen splitting triggering operation may be obtained in a variety of ways, such as detecting input from at least two content sources, or performing a preset screen splitting operation.

In some embodiments, dividing the display output area of the display screen into at least two display areas may include:

if the input of at least two content sources is obtained, determining to obtain split screen trigger operation, and dividing a display output area into at least two display areas at least based on the attribute information of the content sources; or the like, or, alternatively,

if the display screen dividing operation is obtained, determining to obtain the screen dividing triggering operation, and dividing the display output area into at least two display areas at least based on the display screen dividing operation; or the like, or, alternatively,

if the operation of creating at least two desktops on the display screen is obtained, determining to obtain split screen triggering operation, and dividing the display output area into at least two display areas; or the like, or, alternatively,

if the operation of switching the display resolution of the display screen is obtained, determining to obtain a split screen trigger operation, and dividing a display output area into at least two display areas; or the like, or, alternatively,

and if the input of at least two content sources is obtained and the dividing operation acting on the display screen is obtained, determining to obtain the screen dividing trigger operation, and dividing the display output area into at least two display areas at least based on the dividing operation.

It should be noted that, in the embodiment of the present application, whether to obtain the split-screen trigger operation may be determined based on multiple ways, and the display output area is divided accordingly based on the obtained split-screen trigger operation.

In a specific example, if the input of at least two content sources is obtained, for example, the content source input by the electronic device itself and the content source input by at least one external device (e.g., a smart phone, a tablet computer, a notebook computer, etc.) are respectively obtained, it is determined that the split-screen trigger operation is obtained, the display output area may be divided into at least two display areas corresponding to the at least two content sources based on at least the attribute information of the content sources. The attribute information of the content source may include at least a resolution of the content source, a source of the content source, a number of the content sources, an input mode of the content source, and the like.

In another specific example, if a display screen division operation is obtained, it is determined that a screen division trigger operation is obtained, where the display screen division operation at least includes a touch operation for a display screen, a pressing track operation, a touch option selection operation, and the like, and may even be a voice input or a gesture input of a user, and the like; after the display screen dividing operation is obtained, the display output area can be divided into at least two display areas by correspondingly dividing the display output area at least based on the display screen dividing operation.

In yet another specific example, if an operation of creating at least two desktops on a display screen is obtained, it is determined that a split screen trigger operation is obtained, and a display output area is divided into at least two display areas according to the created at least two desktops. In such an example, the at least two desktops each function as an independent display desktop, i.e., the at least two desktops have the same display level and do not have a parent-child relationship with respect to each other.

In still another specific example, if an operation of switching the display resolution of the display screen is obtained, it is determined that a split screen trigger operation is obtained, and the display output area is divided into at least two display areas. In this example, since the display resolution of the display screen is switched, for example: when the screen is switched from 3840 × 2160 to 2880 × 2160, an area (such as a black edge area or a white edge area) on the display screen where no picture is displayed is also used as a split screen area.

In yet another specific example, if the input of at least two content sources is obtained and a dividing operation on the display screen is also obtained, such as one or more of the dividing operations on the display screen listed in the previous examples, it is determined that the screen dividing trigger operation is obtained, the display output area may be divided based on at least the dividing operation to obtain at least two display areas.

That is, in the embodiment of the present application, the display output area may be divided based on a plurality of different criteria, such as content source input and/or a dividing operation, so as to divide the display output area of the display screen into at least two display areas.

Further, when dividing the display output area, wherein the display output area is divided into at least two display areas based on at least the attribute information of the content source, the method may include:

dividing the display output area into at least two display areas based on the number of content sources and/or the resolution of each content source, such that the sum of the resolutions of the at least two display areas is less than or equal to the resolution of the display screen; or the like, or, alternatively,

dividing a display output area into at least two display areas based on target information of a providing end of a content source, so that the sum of resolutions of the at least two display areas is less than or equal to the resolution of a display screen;

and/or the presence of a gas in the atmosphere,

dividing the display output area into at least two display areas based on at least the display screen dividing operation may include:

the method comprises the steps of dividing a display output area into at least two display areas based on an operation track acting on a display screen, or dividing the display output area into at least two display areas based on a selection operation of a split screen control acting on the display screen, or dividing the display output area into at least two display areas based on a voice input and/or a gesture input, so that the sum of resolutions of the at least two display areas is smaller than or equal to the resolution of the display screen, wherein the split screen control is displayed on an OSD window or a system application window on the display screen.

It should be noted that, when dividing the display output area based on the attribute information of the content sources, the display output area may be divided based on the number of content sources and/or the respective resolutions of each content source, and the sum of the resolutions of at least two display areas after division is less than or equal to the resolution of the display screen.

For example, if the number of content sources is two, the display output area is divided into two display areas, and the sum of the resolutions of the two display areas is less than or equal to the resolution of the display screen; if the resolutions of the two content sources are the same, the display output area can be divided into two display areas with the same resolution, and the sum of the resolutions of the two display areas is less than or equal to the resolution of the display screen; if the resolutions of the two content sources are different, the resolutions of the display areas corresponding to the two content sources can be adjusted according to the ratio of the resolutions of the two content sources, and the sum of the resolutions of the two display areas is less than or equal to the resolution of the display screen.

Or, the display output area may be further divided based on target information of the providing end of the content source, where the target information of the providing end of the content source may include at least type information, identification information, application information run by the providing end, and the like of the providing end, and a sum of resolutions of at least two divided display areas is smaller than or equal to a resolution of the display screen.

For example, if the providing terminals of the content source are the electronic device itself and an external smart phone, the display output area may be divided by the type information of the providing terminals, and a split screen ratio of 3:1 may be selected because the screen of the smart phone is generally narrow; the display area of the proportion 3/4 is used for displaying a content source from the electronic device itself, and the display area of the proportion 1/4 is used for displaying a content source from the smartphone.

For another example, if the providing terminals of the content source are the electronic device itself and an external smart phone respectively, the display area may be divided according to the application program information operated by the providing terminals, and if the electronic device is operated by a video playing application and is a landscape playing application, and the smart phone is operated by a reading software and is a portrait playing application, the allocation ratio of 3:1 may be selected; if the electronic equipment and the smart phone both run video playing software and both play horizontally, a split screen ratio of 1:1 can be selected.

It should be noted that the display output area may be divided based on the display screen dividing operation only, or the display output area may be divided by combining the attribute information of the content source with the display screen dividing operation, so as to obtain at least two display areas.

For example, the display output area of the display screen is divided into at least two display output areas based on an operation track acting on the display screen, where the operation track may be operated by a mouse or the like, and for the display screen with a touch screen function, the operation track obtained based on the touch screen or an operation track obtained by other methods may also be used, which is not specifically limited in this embodiment of the application.

Or, the Display output area is divided based On a selection operation of a split Screen control acting On the Display Screen to obtain at least two Display areas, where the split Screen control can be displayed On an On-Screen Display (OSD) window or a system application window On the Display Screen, and for example, the Display output area can be divided into a plurality of preset Display areas by pressing a split Screen key or an electronic split Screen icon through a preset split Screen key or a split Screen icon, or a plurality of split Screen areas can be further selected through a Display interface.

Or, the display output area may be further divided based on a voice input and/or gesture input manner, for example, a user may directly speak a preset voice input and/or make a preset gesture input, and the electronic device may monitor whether the voice input and/or the gesture input of the user is obtained in real time or under a condition that a certain condition is met; the voice input may be acquired through a microphone, and the gesture input may be acquired through a camera. After the voice input and/or the gesture input are acquired, if the condition for dividing the display output area of the display screen is met, the display output area can be divided according to the voice input and/or the gesture input, so that the display output area is divided into display areas with the number and the resolution corresponding to the voice input and/or the gesture input.

It should be noted that, when the display output area is divided into at least two display areas, the sum of the resolutions of the at least two divided display areas may be smaller than or equal to the resolution of the display screen.

Illustratively, the resolution of the display screen is 3840 × 2160 before the display output area is not divided, and if it is determined that 3:1 screen division of the display output area is required according to the attribute information of the content source and/or the display screen dividing operation, the display output area may be divided into two display areas having resolutions of 2880 × 2160 and 960 × 2160, respectively.

Further, in some embodiments, obtaining display identification information of each display area based on at least a split-screen trigger operation may include:

acquiring resolution information of each display area obtained by screen splitting triggering operation, and determining display identification information of each display area based on the resolution information and the display identification information of the display screen; or the like, or, alternatively,

and if the split screen trigger operation is the selection operation of the split screen control on the display screen, correspondingly configuring preset display identification information to each display area.

It should be noted that after the resolution information of each display area is obtained based on the split-screen trigger operation, the display identification information of each display area may be determined based on the resolution information of each display area and the display identification information of the display screen. The display identification information may include EDID information, among others. The display identification information carries information that needs to be modified for the display area, and the modified information at least includes resolution information.

For example, based on the input of at least two content sources, the display identification information of the display screen is modified to obtain the display output information of each display area, so that in the following step, the resolution of each display area is modified by using the display output information of each display area.

Or if the split screen trigger operation is a selection operation of a split screen control acting on the display screen, respectively and correspondingly configuring the display identification information corresponding to the selection operation to each display area. If the 2:1 split screen ratio is selected through the OSD, the display identification information under the preset 2:1 split screen ratio is directly configured to the two display areas respectively.

That is to say, in the embodiment of the present application, the display identification information of the display screen may be modified respectively in combination with the input information (such as resolution, type, and the like) of the content source, so as to obtain the display identification information of each display area obtained by dividing the display output area respectively. Or, the preset display identification information may be directly configured to the divided display area based on a selection operation of a split screen control acting on the display screen.

And S102, controlling the providing end of the content source to adjust the input resolution of each content source at least based on the display identification information.

After the display identification information of each display area is obtained, the resolution input by each content source can be adjusted by controlling the providing end of each content source based on each display identification information. Or, adjusting the resolution of each content source input based on the display identification information in combination with other auxiliary information, where the auxiliary information may include operation state information of the electronic device, for example, operation information of an application program running on the electronic device; the auxiliary information may also include the input mode of the content source, etc.

and obtaining the identification information of the providing end, and controlling the providing end of the content source to adjust the resolution of each content source input based on the identification information and the display identification information.

When the resolution input by the content source is adjusted by controlling the providing end of each content source based on the display identification information of each display area, after the input mode of the content source is obtained, the resolution input by the providing end of each content source may be adjusted based on the input mode of the content source and the display identification information.

It should be noted that, when the resolution input by the content source is adjusted by controlling the providing end of each content source based on the display identification information of each display area, after the identification information of the providing end of the content source is obtained, the resolution input by the providing end of each content source is adjusted based on each identification information and the display identification information. The identification information of the provider may include identification number (ID) information, type information, and the like of the provider.

Further, in some embodiments, controlling the providing end of the content source to adjust the resolution of each content source input based on the input mode and the display identification information may include:

For example, two content sources are respectively given to the display screen through HDMI and DP, and then the display identification information respectively corresponding to the two content sources is respectively given to the providing segments of the respective content sources through the display controller to modify the resolution of the inputs thereof. The display controller may be a control chip, such as a Scalar chip in AIO.

If a first content source of the at least two content sources is presented to the display screen via a first display interface and a second content source is presented to the display screen via a second display interface, wherein the second display interface represents an interface between a host of the electronic device and the display screen that may have the same transport protocol as the first display interface but a different physical structure. At this time, the first display identification information is provided to the first providing terminal through the display controller, wherein the first display identification information is identified as display identification information for outputting a first display area of the first content source, and the first providing terminal represents a providing terminal of the first content source. It is to be understood that the first content source may be one or more and the corresponding first display interface may accordingly comprise one or more.

And simultaneously, second display identification information is given to the corresponding display driver through the display controller, wherein the second display identification information is the display identification information corresponding to a second display area for outputting a second content source, so that the display driver adjusts the resolution input by the second content source. The Display Driver may be a Display Driver (Display Driver) of a Central Processing Unit (CPU).

If a first content source of the at least two content sources is presented to the display screen via the first display interface, a third content source is presented to the display screen via a third display interface, wherein the third display interface may comprise a wireless screen projection interface.

The identification information may include ID information, genre information, and the like of the provider of the content source.

For example, it can be determined whether the providing end of the content source is a mobile phone or a computer, or a television, etc. through the identification information; furthermore, the specific model of the providing end of the content source can be further determined, so that the resolution adjustment range supported by the providing end can be determined, and the resolution adjustment range of the providing end is compared with the resolution indicated by the display identification information to determine the optimal resolution to adjust the resolution output by the content source.

Specifically, for a first content source provided to the display screen through a first display interface (such as HDMI, DP, VGA, etc.), the providing end of the corresponding content source is a first providing end, and the corresponding resolution adjustment range is a first resolution adjustment range; the display controller is used for outputting display identification information corresponding to a first display area of the first content source as first display identification information, and the first resolution adjustment range and the first display identification information are sent to the first providing terminal through the display controller, so that the first providing terminal adjusts the input resolution of the first content source according to the first resolution adjustment range and the first display identification information.

For example, the first provider resolution supports A, B and C types of resolutions, the first display identification information indicates that the input resolution of the first content source needs to be adjusted to D resolution, at this time, A, B, C and D four resolutions can be compared to determine at which resolution the best display effect can be obtained in the first display area, for example, the D resolution is closest to B resolution, and the input resolution of the first content source can be modified to B resolution, so as to achieve the best display effect.

For a second content source provided to the display screen through a second display interface (such as a display interface between the display screen of the electronic device and the host), a providing end of the corresponding content source is a second providing end, and a corresponding resolution adjustment range is a second resolution adjustment range; and the display controller is used for outputting the display identification information corresponding to the second display area of the second content source as second display identification information, sending the second resolution adjustment range and the second display identification information to the display driver, and adjusting the resolution input by the second content source through the display driver.

For a third content source provided to the display screen through a third display interface (such as a wireless turbine interface), the providing end of the corresponding content source is a third providing end, and the corresponding resolution adjustment range is a third resolution adjustment range; and the display controller is used for sending the third resolution adjustment range and the third display identification information to the corresponding screen projection control panel so as to adjust the resolution input by the third content source.

That is to say, the embodiment of the present application may also optimally adjust the resolution by combining the resolution adjustment range of the input end of the content source with the display identification information.

Further, when the resolution of the content source input is adjusted, the display identifier information can be sent to the corresponding providing terminal through the display controller, so that the providing terminal can adjust the resolution of the content source input according to the resolution adjusting range and the display identifier information; alternatively, the resolution adjustment range may be given to the corresponding display driver by the display controller, so that the display driver may adjust the resolution of the content source input according to the resolution adjustment range and the display identification information.

In addition, after the resolution input by the content source is adjusted, the resolution output can be switched by further combining information such as the display area of the display screen, so that the display screen readjusts the resolution of the display area.

Further, the embodiments of the present application may also adjust other parameters besides resolution. Thus, in some embodiments, the method may further comprise:

adjusting at least one of a display parameter, an audio input output control parameter or an image acquisition control parameter of the electronic device other than resolution based on at least the display identification information; or the like, or, alternatively,

adjusting at least one of display parameters, audio input and output control parameters or image acquisition control parameters of the electronic equipment except for resolution based on the display identification information and the input mode of the content source; or the like, or, alternatively,

adjusting at least one of a display parameter other than resolution, an audio input output control parameter, or an image capture control parameter of the electronic device based on the display identification information and the electronic device state information.

It should be noted that, in addition to adjusting the resolution of the content source input, the embodiments of the present application may also adjust one or more of display parameters, audio input output control parameters, or image acquisition control parameters of the electronic device. Such as based on the display identification information, or based on the display identification information and the input mode of the content source, or based on the display identification information and the state information of the electronic device, where the state information of the electronic device may include the display state, the operating state, the power state, and the like of the electronic device.

The embodiment provides a control method, which includes responding to a display output instruction for outputting at least two content sources, and obtaining display identification information of at least two display areas corresponding to the at least two content sources; and controlling the providing end of the content source to adjust the resolution of each content source input at least based on the display identification information. Therefore, when at least two content sources need to be displayed and output, the display identification information of the display areas corresponding to the at least two content sources is obtained, and the resolution input by the providing end of each content source is adjusted according to the display identification information of each display area, so that the resolution adjustment of the input of each content source can be automatically performed under the condition of multi-path content source input, the hot switching of the resolution input by the content sources is realized without additional new insertion action, a plurality of content sources can be displayed at the most appropriate resolution on the display screen of the electronic equipment, and the display quality of the picture is further improved.

In another embodiment of the present application, referring to fig. 2, a flowchart of another control method provided in the embodiment of the present application is shown. As shown in fig. 2, the method may include:

s201, entering a split screen mode.

It should be noted that, in the embodiment of the present application, it may be determined that the electronic device enters the split-screen mode when the split-screen trigger operation is obtained.

In the embodiment of the application, the obtaining of the split-screen trigger operation may include obtaining a preset operation instruction; the preset operation instruction may include the display screen dividing operation and the like in the foregoing embodiment; or when a signal from the external device is detected, determining that the preset operation instruction is acquired.

When the electronic equipment is in the split-screen mode through the preset operation instruction, the electronic equipment is not usually connected with the external equipment, and in this case, the display screen can be directly divided into display areas with preset quantity and resolution according to preset information corresponding to the preset operation instruction.

When the electronic equipment is in a split screen mode through a signal from external equipment, dividing a display screen of the electronic equipment into a first display area and at least one second display area; the first display area is used for displaying a first content source from the electronic equipment, and the second display area is used for displaying a second content source from the external equipment.

Specifically, when the division of the display area is performed, the number of display areas into which the display screen of the electronic device is divided may be determined according to the number of content sources input to the electronic device. For example, when the content sources are from the electronic device itself and an external device, the display screen is divided into two display areas, wherein one display area is used for displaying the content source input of the electronic device itself, and the other display area is used for displaying the content source input of the external device.

S202, modifying the EDID information of each display region through a Scalar chip.

It should be noted that after it is determined that the electronic device enters the split-screen mode, EDID information of each display region after the split-screen mode may be determined by a Scalar chip (or Scalar) in the electronic device according to a split-screen trigger operation or content source information, and EDID information of two or more display regions (also referred to as windows) after the split-screen mode is modified.

And S203, adjusting the resolution of each display area according to the modified EDID information.

It should be noted that, referring to fig. 3, a schematic flow architecture diagram of a control method provided in the embodiment of the present application is shown, and the control method provided in the embodiment of the present application may be performed based on the architecture shown in fig. 3. As shown in fig. 3, the architecture may include a plurality of input terminals for inputting content sources of external devices (including, but not limited to, Type C input, USB input, and DP input shown in fig. 3), a PC signal input terminal for inputting content sources of the electronic device itself (while the electronic device may be brought into the split-screen mode), a Scalar chip for determining EDID modification information of a plurality of display regions, a CPU, a display driver, a display screen for displaying a plurality of content sources, an OSD for bringing the electronic device into the split-screen mode, and the like, and in addition, in the content source input, a content source (not shown in the figure) for wirelessly projecting a screen to the display screen may be further included. In the embodiment of the present application, the control method is described in detail with reference to the architecture shown in fig. 3.

After signals of the OSD or the external equipment enter a split screen mode, under the condition that a content source of the external equipment inputs, the Scalar chip sends modified EDID information of a display area corresponding to the content source of the external equipment to a providing end of the content source, the providing end (namely an input signal source) of the content source adjusts the resolution ratio input by the content source according to the modified EDID information, and the Scalar chip displays the adjusted content source in a corresponding display area of a display screen of the electronic equipment.

That is to say, for a content source (such as a video signal) input through HDMI, Universal Serial Bus (USB), DP, Type C, and the like, the modified EDID information can be directly given to a providing end (input end) of the content source through the Scalar chip, so that the providing end of the content source can modify the input resolution of the content source according to the modified EDID information to achieve the correct resolution.

On the other hand, for the side of the electronic device (e.g. AIO), i.e. the side of the Personal Computer (PC) where the signal is input, the reconnection is not disconnected, so that the resolution cannot be switched again according to the EDID information fed back by the Scalar chip, and the correct resolution cannot be modified. In view of this problem, in the embodiment of the present application, the Scalar chip sends the modified EDID information to the Display Driver of the CPU, the Display Driver performs hot switching, and the resolution of the content source input is redesigned according to the EDID information fed back by the Scalar chip. And after the correct resolution is designed, displaying the adjusted content source in a corresponding display area of a display screen of the electronic equipment through the Scalar chip.

For example, refer to fig. 4, which shows a schematic view of a display area of a display screen provided in an embodiment of the present application. Where a in fig. 4 indicates an example of a display area in the case of a two-screen display (which may be a display screen with a resolution of 3840 × 2160 divided into two display areas with resolutions of 1920 × 2160 and 1920 × 2160), in this case, the external device may be a Notebook computer (Notebook). B in fig. 4 represents an example of a display area in the case of a three-to-one screen (it may be that a display screen having a resolution of 3840 × 2160 is divided into two display areas having resolutions of 2880 × 2160 and 960 × 2160), in which case the external device may be a mobile Phone (Phone).

In addition, for the case that the electronic device enters the split-screen mode according to the preset operation instruction, at this time, since there is no content source input of the external device, the display area of the display screen may include the display area of the electronic device itself and a plurality of display areas that do not display any content. After that, if the external device is connected, the EDID information of the display area may be readjusted according to the information such as the resolution and/or the type of the external device, and the resolution input by the content source of the external device may be adjusted to fit the display area, and the display area may be adjusted according to the type information of the external device.

That is to say, the embodiment of the present application provides a control method, which can detect EDID input (such as an input video signal) from a content source through a Scalar chip, convert an obtained EDID modification signal into other command signals, respectively transmit the command signals to a display driver of a CPU and a providing terminal of the content source to perform hot switching EDID, and respectively modify the input resolution of the content source and then display the modified EDID in a corresponding display region. When the split screen mode is selected through OSD, the Scalar chip modifies EDID of two or more windows after split screen, such as 3840 × 2160 split screen when yoga27 is not split screen, and after selecting two split screens, the resolution of two sides will become 1920 × 2160 and 1920 × 2160, and when selecting three-ratio split screen, the resolution will automatically become 2880 × 2160 and 960 × 2160. At this time, the modified EDID information can be directly given to the input end through the Scalar chip for the video signal input by the HDMI, the Type C or the like, so that the resolution of the input video signal is modified by the input end, and the correct resolution is achieved. And one side of the AIO, namely one side of the PC signal input, because the reconnection is not disconnected, the resolution cannot be switched again according to the EDID information fed back by the Scalar chip, and the correct resolution cannot be modified. Therefore, the resolution ratio can be automatically identified and adjusted when the multi-channel source input is split on the integrated machine, and the display quality of the picture is improved.
