As shown in FIG. 1, the foldable electronic device 100 includes a foldable display 1, an angle sensor 2, and a processor 3.

The angle sensor 2 is used to detect a folding angle of the foldable display screen 1. The processor 3 is electrically connected to the angle sensor 2 and is configured to control switching of the folding angle displayed on the foldable display 1 when it is determined that the folding angle detected by the angle sensor 2 has changed and the change value exceeds a preset threshold. Application interface.

Therefore, in this application, by folding the foldable display 1 and the folding angle exceeds a preset threshold, different application interfaces can be displayed, which improves the convenience of display control of the application interface.

Wherein, in some embodiments, the angle sensor 2 detects the folding angle of the foldable display 1 every preset time interval (for example, 0.5 seconds, 1 second, etc.) to obtain multiple folding angle data, and the processor 3 When receiving the multiple folding angle data and determining that the adjacently acquired folding angles are not equal, it is determined that the folding angle detected by the angle sensor 2 has changed, and the processor 3 determines the currently acquired When the difference between the folding angle and the folding angle obtained before the moment when it is determined that the folding angle has changed exceeds a preset threshold, it is determined that the change value of the folding angle exceeds the preset threshold.

In some embodiments, the foldable display screen 1 is in an initial state when it is in a flat state, and the folding angle is 0 degrees, and the folding angle of the foldable display screen 1 is relative to an angle bent in the flat state.

As shown in FIG. 2, the foldable display screen 1 includes a display surface S1 and a non-display surface S2, and the display surface S1 and the non-display surface S2 are opposite surfaces. The display surface S1 further includes two sub-surfaces, and the non-display surface S2 further includes two sub-surfaces. The folding angle of the foldable display is specifically an angle between two sub-surfaces of the non-display surface S2. The folding angle detected by the angle sensor 2 is also an included angle between two sub-surfaces of the non-display surface S2 of the foldable display screen 1. That is, after the folding display screen 1 is folded, the display surface S1 will be on the outside and in a state where it can always be viewed. Obviously, in some embodiments, the folding angle of the foldable display screen may also be an included angle between two sub-surfaces of the display surface S1.

In the present application, the foldable display 1 may be a main display structure of the foldable electronic device 100, and an outer frame structure of the foldable display 1 is the outer frame structure of the foldable electronic device. The non-display surface S2 of the foldable display screen 1 is the back shell of the foldable electronic device 100, and the processor 3 and the like are disposed in the back shell or the outer frame. Therefore, folding the foldable display 1 described in this application is to fold the foldable electronic device 1.

As shown in FIG. 2, in some embodiments, the foldable display screen 1 includes a rotation axis R1, and the foldable display screen 1 includes a first sub display screen 11 and a second sub display screen 12, and the first sub display screen 1 The display screen 11 is fixedly connected to the rotation axis R1, and the second sub display screen 12 is rotatably connected to the rotation axis R1, so that the first sub display screen 11 and the second sub display screen 12 can rotate around the rotation axis R1, and The folding angle of the foldable display 1 is changed. Among them, FIG. 2 is only a schematic diagram, the rotating shaft R1 may include a sleeve and a rotating rod passing through the sleeve, the first sub-display screen 11 may be fixedly connected to the sleeve, and the second The sub-display screen 12 is fixedly connected to the rotation lever, and the second sub-display screen 12 can be bent / folded relative to the first sub-display screen 11 by rotating the rotation lever relative to the sleeve. Of course, the rotation axis is not limited to a physical rotation axis, and may also be a virtual rotation axis, as long as the first sub-display screen and the second sub-display screen can be rotated around it.

The angle sensor 3 may specifically be a resistive angle sensor, a capacitive angle sensor, a hall angle sensor, etc. provided on the rotating shaft R1, and the folding is determined by detecting the rotation angle of the rotating shaft R1 relative to the second sub-display screen 12. angle. For example, suppose that the rotation angle of the first sub-display screen 11 and the second sub-display screen 12 when they are expanded in parallel is zero, that is, the folding angle is zero, and then the rotation of the second sub-display screen 12 relative to the rotation axis R1 is detected. The angle serves as the folding angle.

In some embodiments, as shown in FIG. 3, the foldable display screen 1 may be an organic light-emitting diode (OLED) display screen, which has the characteristics of being bendable, twistable, and foldable. Better color and contrast, and ultra-thin features. A plurality of capacitive grid sensors (not shown) may be distributed in the foldable display screen 1, and the processor 3 may detect a folding angle at which the foldable display screen 1 is folded by an angle sensor 2, and may pass The change in voltage generated by the capacitive grid sensor at the bend of the foldable display screen 1 determines the position where the display screen is folded to obtain the folding line L. In another embodiment, a contact point may be set between the first sub-display screen 11 and the second sub-display screen 12. When the folding display screen 1 is in a flat state, the connection between the contact points is broken. When the display screen 1 is bent, a connection is established between the contact points. Therefore, the position where the flexible screen is bent can be determined by changing the path between the contact points to obtain the folding line L.

Therefore, in the embodiment shown in FIG. 3, the foldable display screen 1 may not be limited to being folded at a fixed position, and may be folded at any suitable place.

After the processor 3 obtains the folding line L, the processor 3 further divides the foldable display screen 1 into a first sub display screen 11 and a second sub display screen 12 through the folding line L. That is, the processor 3 logically divides the foldable display screen 1 into a first sub display screen 11 and a second sub display screen 12 through a folding line L.

In some embodiments, please refer to FIG. 4. When the foldable display 1 is a flexible display, the angle sensor 2 may include a plurality of

infrared emitters

21 and 4 respectively disposed on four sides of the foldable display 1. Several infrared receivers 22. As shown in FIG. 4, each side of the foldable display screen 1 can be provided with multiple infrared transmitters 21 and multiple infrared receivers 22. The processor 3 can also control the folding line L after determining the folding line L. The infrared transmitter 21 on the vertical side near the folding line L emits infrared light. When the folding angle changes, the infrared receiver 22 receiving the infrared light will also change. The processor 2 can The infrared receiver 22 of the infrared light determines the corresponding folding angle.

In some embodiments, the plurality of infrared transmitters 21 and the plurality of infrared receivers 22 are disposed on the non-display surface S2 of the foldable display screen 1.

In some embodiments, when the processor 3 determines that the folding angle detected by the angle sensor 2 changes and the change value exceeds a preset threshold, the processor 3 controls to switch the application interface displayed on the foldable display 1, which may include: : The processor 3 determines a target application when it determines that the folding angle detected by the angle sensor 2 changes and the change value exceeds a preset threshold; and controls the application program currently displayed on the foldable display 1 The application interface switches to the application interface of the target application.

For example, when the foldable display 1 is currently displaying an application A, assuming an application interface of a video player, then the application A is in the foreground, and if the foldable electronic device 100 is running the application B in the background, Assume WeChat.

Therefore, when the user receives a WeChat message reminder or wants to return to WeChat to view the information when the user is watching a video using a video player, the foldable display 1 can be folded.

Suppose that when watching a video using a video player, the folding angle θ of the foldable display 1 is a, and after the user folds the foldable display 1, the folding angle of the foldable display 1 detected by the angle sensor 2 changes. Is b, when the processor 3 determines that | ab | reaches the set threshold T, it controls to switch the application interface of the video player displayed on the foldable display 1 to an application interface of WeChat. That is, at this time, WeChat will be switched to the foreground display, and for users, the video player will be switched to the background.

In some embodiments, when the processor 3 determines that the folding angle detected by the angle sensor 2 changes and the change value exceeds a preset threshold, determining the target application program may specifically include: the processor 3 is determining When the folding angle detected by the angle sensor 2 changes and the change value exceeds a preset threshold, the change trend of the folding angle is further determined; and when it is determined that the change trend of the folding angle detected by the angle sensor 2 is the first trend , Determine that the application to which the last displayed application interface belongs is the target application. The first trend is a decreasing trend.

Thus, when the user switches to the application interface of application B by increasing the folding angle, and needs to return to application A after using application B, the user folds the device again, so that the folding angle θ returns from angle b to angle a , You can switch to the previously used application A. At this time, application A is in the foreground and application B is in the background.

In some embodiments, when the processor 3 determines that the change trend of the folding angle detected by the angle sensor 2 is the second trend, it determines that any other application in the background is the target application, or Priority of other applications in the background, determine the highest priority application as the target application.

For example, the applications in the background also have different priorities according to the frequency of use and importance level of the user, for example, applications with high frequency and high importance have high priority.

Wherein, the second trend may be a larger trend. Obviously, in other embodiments, the first trend may be a larger trend, and the second trend may also be a smaller trend.

Therefore, when the user is using the current application A, the user needs to view the information in the application B, so the user can fold the foldable display 1 by a certain angle, and when the value of the folding angle changes to a preset threshold, the mobile device switches At the application interface displaying the application B, the user can view the content in the application B according to his own needs. After the viewing, the user can fold the foldable display 1 to the previous angle, that is, switch back to the application interface of the application A. This completes the fast switching operation between different applications, and improves the user's short experience of viewing the interactive experience of other applications.

In other embodiments, the processor 3 controls to switch the application interface displayed on the foldable display 1 when it determines that the folding angle detected by the angle sensor 2 changes and the change value exceeds a preset threshold, It may include: when the processor 3 determines that the folding angle detected by the angle sensor 2 changes and the change value exceeds a preset threshold, determining the target state; and controlling an application program currently displayed on the foldable display 1 The application interface in a certain state is switched to the application interface in the target state. The switching of the application interface in this application includes switching of the application interface of different applications, and also includes switching between the application interface in different states of the same application or the application interface displaying different content.

For example, when the application displayed on the foldable display is a video player and the current state is a playback state, the processor 3 and the processor 3 determine that the folding angle detected by the angle sensor 2 has changed. When it is determined that the target state is a pause state when the change value exceeds a preset threshold, the control switches an application interface in which the video player is in a playing state to an application interface in a paused state.

Specifically, when the application A being used by the user is a video player and watching a video, the folding angle θ of the foldable display 1 at this time is set to a. When the user needs to leave temporarily due to other reasons, the user needs to play the video. For a pause operation, the foldable display 1 can be folded. When the processor 2 detects that the value of the folding angle θ is b and determines that the change value of the folding angle | ab | reaches a preset threshold T, it controls to pause playback and controls to switch the application interface Go to the suspended application interface.

In some embodiments, when the processor 3 determines that the folding angle detected by the angle sensor 2 changes and the change value exceeds a preset threshold, determining the target state may specifically include: the processor determines When the folding angle detected by the angle sensor 2 changes and the change value exceeds a preset threshold, the change trend of the folding angle is further determined; when it is determined that the change trend of the folding angle detected by the angle sensor 2 is the first trend, it is determined that the The state of the application interface of the displayed application at a time is the target state. The state of the application interface displayed last time is a state different from the current state of the application interface of the application at the last moment, or the state of the application program displayed last time is different from the current state The displayed application interface is in a different state and is the closest state to the currently displayed application interface.

Therefore, when the user switches the application interface of the video player to the paused application interface by increasing the folding angle, when the user finishes processing other tasks and continues to watch the video, the user can fold the foldable display 1 again to make the folding The angle θ returns from angle b to angle a, and the paused video can be resumed.

In some embodiments, when the processor 3 determines that the change trend of the folding angle detected by the angle sensor 2 is the second trend, it determines that any other state in which the application program is located is a target state, or And, according to the priorities of other states of the application, determine the state with the highest priority as the target state. When the application is a video player, other states may also include a fast-forward state, a fast-reverse state, and the like. By folding the foldable display 1 by changing the folding angle in a second trend, a random state may be entered.

For example, the application status also has different priorities according to the frequency of use by the user, for example, a status with a high frequency of use has a high priority. Specifically, for example, the priority of the playback state and the pause state is higher than the fast forward state and the fast reverse state, when the processor 3 determines that the change trend of the folding angle detected by the angle sensor 2 is the second trend , When it is determined that the state other than the current state includes the playback state, fast forward state, and fast rewind state, it is determined that the playback state is the target state.

The first trend may be a decreasing trend, and the second trend may be a increasing trend. Obviously, in other embodiments, the first trend may be a larger trend, and the second trend may also be a smaller trend.

Therefore, when a user uses a video player to watch a video or a music player plays music, sometimes he needs to leave for a short time to handle other things. The current program needs to be paused. The folding angle can be used to implement pause and resume playback controls, without the user having to click Specific pause / play buttons to control, improve the convenience of operation, and improve the user experience.

The processor 3 is further configured to determine the first sub display screen 11 and the second sub display screen 12 formed by the bending when the foldable display screen 1 is bent.

As mentioned above, whether it is the hinge connection method or the foldable display 1 is a flexible display, the foldable display 1 will form the first sub-display divided by the folding line L or the hinge during the bending. Screen 11 and the second sub-display screen 12. Therefore, when the foldable display 1 includes a first sub-display 11 and a second sub-display 12 connected by a hinge, the processor 3 may determine that the screen area on both sides of the hinge is the first sub-display. Screen 11 and the second sub-display screen 12. When the foldable display screen 1 is a flexible display screen, the processor 3 may determine that two sides of the fold line L1 are the first sub display screen 11 and the second sub display screen 12 according to the fold line L, respectively.

The processor 3 is further configured to, when it is determined that the folding angle detected by the angle sensor 2 is less than or equal to a preset angle, control the application interface to be currently displayed on the first sub-display screen 11 and the second sub-display screen 12 And when it is determined that the folding angle detected by the angle sensor 2 is greater than a preset angle, controlling to display an application interface to be currently displayed on the entire screen area of the foldable display 1. The preset angle may be 120 degrees.

In some embodiments, when the processor 3 determines that the folding angle detected by the angle sensor 2 is less than or equal to a preset angle, it determines that the first sub-display 11 or the second sub-display 12 closest to the human body is the target sub-display. Display screen, and control the application interface to be displayed on the target sub-display screen.

Referring to FIG. 5, in some embodiments, a plurality of infrared sensors H1 are further distributed on the display surface S1 of the foldable display screen 1, and the plurality of infrared sensors H1 are used to detect a human body facing the display surface S1. According to the distance detected by the plurality of infrared sensors H1, the processor 3 determines that the infrared sensor H1 having the smallest detected distance is located on the first sub-display screen 11 or the second sub-display screen 12 to be closest to the human body When it is determined that the folding angle detected by the angle sensor 2 is less than or equal to a preset angle, the control displays an application interface to be currently displayed on the target sub-display screen.

For example, as shown in FIG. 5, when the processor 3 determines that the first sub-display screen 11 is the target sub-display screen, it controls to display an application interface of the application program A to be currently displayed on the first sub-display screen 11, The second sub-display 12 is not displayed, thereby saving energy consumption.
