The implementations described in the following exemplary examples do not represent all implementations consistent with the present disclosure. Rather, they are merely examples of apparatuses and methods consistent with aspects of the present disclosure as recited in the appended claims.

The "electronic device" mentioned in this article can be a smart phone, a tablet computer, an e-book reader, a multimedia player, a laptop computer, a smart camera or a smart video camera, and so on.

FIG. 1A shows a schematic structural diagram of a device with a protective case according to an exemplary embodiment. The device with a protective case includes an electronic device 10 and a protective case 20 with a window.

The electronic device 10 includes a display screen 11 and a capacitor disposed under the display screen 11 .

The edge of the sunroof area 21 on the window protection cover 20 is provided with predetermined materials 22, and these predetermined materials 22 change the state of the capacitor 12a at the relative position under the display screen 11 when the opening and closing state of the window protection cover 20 changes.

Wherein, the opening and closing states of the window protection cover 20 include a closed state when it covers the display screen 11 , and an open state when it does not cover the display screen 11 .

In order to ensure the function of displaying and controlling the standby of the electronic device 10 after the window opening protective cover 20 is closed, the electronic device 10 may also be provided with a Hall sensor 13 . Correspondingly, a magnet 23 is disposed in the window-opening protective cover 20 , and the magnetic field lines of the magnet 23 pass through the Hall sensor 13 when the window-opening protective cover 20 covers the display screen 11 .

For details, please refer to FIG. 1B , which is a schematic view of an open state and a closed state of a window protection cover according to an exemplary embodiment. Referring to FIG. 1A and FIG. 1B , a magnet 23 is provided on the window protection cover 20 , and a Hall sensor 13 is provided on the electronic device 10 , wherein the relative positions of the magnet 23 and the Hall sensor 13 are set as follows: when the window protection cover 20 When closed (that is, the windowed protective cover 20 covers the display screen 11 of the electronic device 10 ), the projection of the magnet 23 on the electronic device 10 and the straight line formed by the Hall sensor 13 are parallel to the lateral direction of the electronic device 10 . In other words, when the windowed protective case 20 is closed, the projection of the magnet 23 on the electronic device 10 is aligned with the Hall sensor 13 in the lateral direction of the electronic device 10 , where the magnet 23 is located on the left side of the Hall sensor 13 .

Since the distance between the magnet 23 aligned in the lateral direction and the Hall sensor 13 can be set, the magnetic field lines of the magnet 23 can pass through the Hall sensor 13 when the window protection cover 20 is closed. Please refer to Fig. 1C, which is a schematic diagram of when the magnetic force lines of the magnet pass through the Hall sensor after the window protection cover is closed in Fig. 1B, the magnetic force lines of the magnet 23 (that is, the magnetic force lines from the N pole to the S pole of the magnet 23) can pass through Pass the Hall sensor 13. When the Hall sensor 13 senses the passing magnetic force lines, it can be determined that the window-opening protective cover 20 is closed; when the Hall sensor 13 does not sense the magnetic force lines, it can be determined that the window-opening protective cover 20 is open.

And when the window protection cover 20 is opened, the magnetic field lines of the magnet 23 no longer pass through the Hall sensor 13 . Please refer to FIG. 1D , which is a schematic diagram of when the magnetic flux of the magnet does not pass through the Hall sensor after the window protection cover is closed in FIG. 1B . At this time, it is easy to cause the magnetic flux of the magnet 23 to no longer pass through the Hall sensor 13 .

To sum up, in the device with the protective cover provided by the embodiment of the present invention, since the edge of the skylight area on the window protective cover is provided with predetermined materials, when the opening and closing state of the window protective cover changes, these predetermined materials will The state of the capacitor at the relative position under the display screen can be changed, so it is only necessary to determine the capacitance of the state transmission change when the window protection cover is closed, and then the lock on the display screen corresponding to the window opening area of the window protection cover can be determined screen display area, the electronic device can display the preset information of the interface theme in the lock screen display area in the lock screen state, which provides the necessary conditions for the mutual matching of the preset information of the interface theme and the window opening area of the window protection cover .

It should be added that the protective window cover 20 in FIG. 1A can also form an embodiment alone, that is, an exemplary embodiment of the present disclosure provides a protective window cover. The edge is provided with a predetermined material. When the window-opening protective cover is used in conjunction with electronic equipment, when the opening and closing state of the window-opening protective cover changes, the predetermined material changes the state of the capacitor at the relative position under the display screen of the electronic device used in conjunction with the window-opening protective cover. Here The open and closed states mentioned include the closed state when the display screen of the electronic device is covered, and the open state when the display screen is not covered.

Fig. 2A is a flow chart of an information display method according to an exemplary embodiment, the information display method can be applied to the electronic device shown in Fig. 1A, and the electronic device is matched with the window-opening protective case shown in Fig. 1A use. The information display methods include:

Step 201, acquiring the sensing parameters of the Hall sensor to the magnetic field lines.

The Hall sensor provided on the electronic device can sense the magnetic force lines passing through the Hall sensor, therefore, the electronic device can obtain the sensing parameters generated when the Hall sensor is set to sense the magnetic force line.

Generally speaking, when the Hall sensor does not sense that there are lines of magnetic force passing through the Hall sensor, the value of the sensing parameter is the first sensing value; when the Hall sensor senses that lines of magnetic force passing through the Hall sensor, the value of the sensing parameter is The value of is the second sensing value, and the first sensing value is different from the second sensing value.

In practical applications, when the window protection cover is in the open state, the distance between the magnet on the window protection cover and the Hall sensor on the electronic device is relatively far, so the magnetic force lines of the magnet cannot pass through the Hall sensor. The sensor cannot sense the magnetic force lines, and at this time, the sensing parameter of the Hall sensor is the first sensing value. Therefore, when the sensing parameter of the Hall sensor is the first sensing value, it indicates that the window-opening protective cover is in an open state.

And when the window-opening protective cover is closed, that is, the window-opening protective cover covers the display screen of the electronic device, because the projection of the magnet on the electronic device is aligned with the Hall sensor in the lateral direction of the electronic device, and the magnet is located near the Hall sensor. One side of the Hall sensor, so the magnetic force lines of the magnet can pass through the Hall sensor, and the Hall sensor can sense the magnetic force lines. At this time, the sensing parameter of the Hall sensor is the second sensing value. Therefore, when the sensing parameter of the Hall sensor is the second sensing value, it indicates that the window opening protection cover is in a closed state.

Step 202 , when the sensing parameter of the Hall sensor changes from the first sensing value of not sensing the magnetic force lines to the second sensing value of sensing the magnetic flux lines, it is determined that the window protection cover changes from the open state to the closed state.

Generally speaking, when the window-opening protective cover is closed, the electronic device will enter the lock screen state, but when the window-opening protective cover is always in the closed state, the electronic device will not execute the mechanism of controlling the electronic device to lock the screen, but When the window-opening protective cover changes from an open state to a closed state, the electronic device enters a screen-locked state.

Since when the sensing parameter of the Hall sensor is the first sensing value, it indicates that the window protection cover is in an open state, and when the sensing parameter of the Hall sensor is the second sensing value, it indicates that the window protection cover is in a closed state, so in When the sensing parameter of the Hall sensor changes from the first sensing value of not sensing the magnetic force lines to the second sensing value of sensing the magnetic force lines, it is determined that the window protection cover changes from the open state to the closed state.

In practical applications, when the electronic device determines that the window protection cover changes from the open state to the closed state, it usually means that the display screen will enter the lock screen state or standby state. There is no touch operation for sensing, so it will be directly powered off. However, in this embodiment, when it is determined that the window protection cover changes from the open state to the closed state, it is necessary to further determine through the state change of the capacitance that the window opening area of the window protection cover is in the mapping area of the display screen. Each capacitor cannot identify the predetermined material set on the window protection cover, and it is necessary to control each capacitor under the display screen so that it does not lose power.

Step 203, when the window-opening protective cover changes from the open state to the closed state, obtain the capacitance of the state change under the display screen of the electronic device.

The predetermined material mentioned here changes the state of the capacitance at the relative position under the display screen when the opening and closing state of the window protection cover changes.

When the window protection cover changes from the open state to the closed state, it indicates that the electronic device needs to enter the lock screen state. In order to enable the predetermined information on the home page interface in the lock screen state to be displayed on the display screen, it corresponds to the window area of the window protection cover In the area where the window is opened, the electronic device needs to identify the windowed area.

In one implementation, the edges of the windowed area are provided with a predetermined material that can be identified by the display screen. For example, when this predetermined material is close to the display screen, the state of the capacitor set at a relative position under the display screen will change, while the capacitors set at other positions under the display screen will not be affected by the predetermined material, so even if the window cover covers On the display screen, the state of the capacitor at a position not opposite to the predetermined material under the display screen will not change.

Obviously, the state of the capacitance in this embodiment refers to the state generated by the touch operation and the state generated by the non-touch operation, and different states are generally distinguished by high and low levels.

The predetermined material disposed on the edge of the windowed area can affect the high and low levels of the relative positional capacitance, thus causing the state of the capacitance to change. For example, when there is no touch operation and the window protection cover is in the open state, that is, when the predetermined material is far away from the capacitor, the capacitor is at a low level. At this time, the state of the capacitor can be considered as the first state; The protective cover is in the closed state, that is, when there is no touch operation and the predetermined material is relatively close to the capacitor, the capacitor becomes a high level. At this time, the state of the capacitor can be considered as the second state.

Please refer to FIG. 2B , which is a schematic diagram showing the state of capacitance under the display screen according to an exemplary embodiment. When the window protection cover is opened, each capacitor 12a under the display screen is not triggered by the user. , are in the same state, as shown in the left figure in Figure 2B; when the window protection cover is closed, each capacitor under the display screen is connected to the edge of the window area of the window protection cover without being triggered by the user. The state of the capacitance 12b at the position where the predetermined material faces changes, as shown in the right diagram of FIG. 2B.

Step 204 , mapping the area formed by each capacitor whose state has changed to the display screen to form a lock screen display area corresponding to the windowed area.

Since the electronic device can determine the position of each capacitor whose state changes after the window-opening protective cover is closed, the area formed by these capacitors can be mapped to the display screen to form a lock screen display area corresponding to the window-opening area.

That is to say, the area formed by each capacitance mapped to the points on the display screen is the lock screen display area.

Step 205, controlling the display screen to enter the lock screen state, and controlling the lock screen display area to display predetermined information of the current interface theme in the lock screen state.

After the electronic device determines the lock screen display area, it can control the display screen to enter the lock screen state, and control the lock screen display area in the lock screen state to display predetermined information of the current interface theme.

Generally speaking, after the electronic device enters the lock screen state, the capacitance under the display screen of the electronic device can recognize the touch operation except for the capacitance opposite to the area where the unlocking control is allowed to be manipulated, and the rest of the capacitors will not recognize the touch operation.

When the electronic device is matched with the protective case, the protective case is in a closed state, that is, when the protective case covers the display screen of the electronic device, the electronic device will enter a screen-locked state.

Optionally, when the sensing parameter of the Hall sensor changes from the second sensing value sensing the magnetic force lines to the first sensing value not sensing the magnetic flux lines, it is determined that the window protection cover changes from the closed state to the open state, and the electronic device controls the display The screen enters the unlocked state.

To sum up, the information display method provided by the embodiment of the present invention identifies the predetermined material set on the edge of the sunroof area on the window protection cover to determine the display screen corresponding to the window area of the window protection cover. The display area of the lock screen, and in the lock screen state, the predetermined information of the interface theme is displayed in the display area of the lock screen, which solves the problem in the window opening area of the window protection cover caused by the change of the interface theme of the electronic device in the related art The problem that the practical information of the interface theme may not be displayed can achieve the effect that the predetermined information of the interface theme can be displayed in the window area of the current window protection cover in real time.

The following are device embodiments of the present disclosure, which can be used to implement the method embodiments of the present disclosure. For details not disclosed in the disclosed device embodiments, please refer to the disclosed method embodiments.

Fig. 3A is a block diagram showing an information display device according to an exemplary embodiment, and the information display device may be implemented as the electronic device shown in Fig. 1 through software, hardware or a combination of software and hardware. The information display apparatus may include: a first acquisition module 301 , a mapping module 302 , a lock screen module 303 and a display module 304 .

The first acquisition module 301 may be configured to acquire the capacitance of the state change under the display screen of the electronic device when the window-opening protective cover changes from an open state to a closed state, and the predetermined material is in the opening state of the window-opening protective cover. When the closed state changes, change the state of the capacitor at the relative position under the display screen.

When the window protection cover changes from the open state to the closed state, it indicates that the electronic device needs to enter the lock screen state. In order to enable the predetermined information on the home page interface in the lock screen state to be displayed on the display screen, it corresponds to the window area of the window protection cover In the area where the window is opened, the electronic device needs to identify the windowed area.

In one implementation, the edges of the windowed area are provided with a predetermined material that can be identified by the display screen. For example, when this predetermined material is close to the display screen, the state of the capacitor set at a relative position under the display screen will change, while the capacitors set at other positions under the display screen will not be affected by the predetermined material, so even if the window cover covers On the display screen, the state of the capacitor at a position not opposite to the predetermined material under the display screen will not change.

Obviously, the state of the capacitance in this embodiment refers to the state generated by the touch operation and the state generated by the non-touch operation, and different states are generally distinguished by high and low levels.

The predetermined material disposed on the edge of the windowed area can affect the high and low levels of the relative positional capacitance, thus causing the state of the capacitance to change. For example, when there is no touch operation and the window protection cover is in the open state, that is, when the predetermined material is far away from the capacitor, the capacitor is at a low level. At this time, the state of the capacitor can be considered as the first state; The protective cover is in the closed state, that is, when there is no touch operation and the predetermined material is relatively close to the capacitor, the capacitor becomes a high level. At this time, the state of the capacitor can be considered as the second state.

The mapping module 302 may be configured to map the region formed by each capacitance obtained by the first obtaining module 301 with state changes to the display screen to form a lock screen display region corresponding to the windowed region.

Since the electronic device can determine the position of each capacitor whose state changes after the window-opening protective cover is closed, the area formed by these capacitors can be mapped to the display screen to form a lock screen display area corresponding to the window-opening area.

That is to say, the area formed by each capacitance mapped to the points on the display screen is the lock screen display area.

The screen lock module 303 may be configured to control the display screen to enter a screen lock state.

After the electronic device determines the lock screen display area, it can control the display screen to enter the lock screen state.

The display module 304 may be configured to control the display area of the lock screen to display predetermined information of the current interface theme in the lock screen state.

The electronic device can control the lock screen display area in the lock screen state to display predetermined information of the current interface theme.

Generally speaking, after the electronic device enters the lock screen state, the capacitance under the display screen of the electronic device can recognize the touch operation except for the capacitance opposite to the area where the unlocking control is allowed to be manipulated, and the rest of the capacitors will not recognize the touch operation.

When the electronic device is matched with the protective case, the protective case is in a closed state, that is, when the protective case covers the display screen of the electronic device, the electronic device will enter a screen-locked state.

In a possible implementation manner, the electronic device is provided with a Hall sensor, the window-opening protective cover is provided with a magnet, and the magnetic field lines of the magnet pass through the Hall sensor when the protective cover covers the display screen, The apparatus may further include: a second acquiring module 305 and a judging module 306, as shown in FIG. 3B .

The second acquisition module 305 may be configured to acquire the sensing parameters of the Hall sensor to the magnetic field lines.

The Hall sensor provided on the electronic device can sense the magnetic force lines passing through the Hall sensor, therefore, the electronic device can obtain the sensing parameters generated when the Hall sensor is set to sense the magnetic force line.

Generally speaking, when the Hall sensor does not sense that there are lines of magnetic force passing through the Hall sensor, the value of the sensing parameter is the first sensing value; when the Hall sensor senses that lines of magnetic force passing through the Hall sensor, the value of the sensing parameter is The value of is the second sensing value, and the first sensing value is different from the second sensing value.

In practical applications, when the window protection cover is in the open state, the distance between the magnet on the window protection cover and the Hall sensor on the electronic device is relatively far, so the magnetic force lines of the magnet cannot pass through the Hall sensor. The sensor cannot sense the magnetic force lines, and at this time, the sensing parameter of the Hall sensor is the first sensing value. Therefore, when the sensing parameter of the Hall sensor is the first sensing value, it indicates that the window-opening protective cover is in an open state.

And when the window-opening protective cover is closed, that is, the window-opening protective cover covers the display screen of the electronic device, because the projection of the magnet on the electronic device is aligned with the Hall sensor in the lateral direction of the electronic device, and the magnet is located near the Hall sensor. One side of the Hall sensor, so the magnetic force lines of the magnet can pass through the Hall sensor, and the Hall sensor can sense the magnetic force lines. At this time, the sensing parameter of the Hall sensor is the second sensing value. Therefore, when the sensing parameter of the Hall sensor is the second sensing value, it indicates that the window opening protection cover is in a closed state.

The determining module 306 may be configured to determine whether the Hall sensor is on or off when the sensing parameter of the Hall sensor acquired by the second obtaining module 305 changes from the first sensing value of not sensing the magnetic force lines to the second sensing value of sensing the magnetic force lines. The window protector changes from the open state to the closed state.

Generally speaking, when the window-opening protective cover is closed, the electronic device will enter the lock screen state, but when the window-opening protective cover is always in the closed state, the electronic device will not execute the mechanism of controlling the electronic device to lock the screen, but When the window-opening protective cover changes from an open state to a closed state, the electronic device enters a screen-locked state.

Since when the sensing parameter of the Hall sensor is the first sensing value, it indicates that the window protection cover is in an open state, and when the sensing parameter of the Hall sensor is the second sensing value, it indicates that the window protection cover is in a closed state, so in When the sensing parameter of the Hall sensor changes from the first sensing value of not sensing the magnetic force lines to the second sensing value of sensing the magnetic force lines, it is determined that the window protection cover changes from the open state to the closed state.

In practical applications, when the electronic device determines that the window protection cover changes from the open state to the closed state, it usually means that the display screen will enter the lock screen state or standby state. There is no touch operation for sensing, so it will be directly powered off. However, in this embodiment, when it is determined that the window protection cover changes from the open state to the closed state, it is necessary to further determine through the state change of the capacitance that the window opening area of the window protection cover is in the mapping area of the display screen.
