Detailed Description

The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

Referring to fig. 1 and fig. 2 together, fig. 1 is a block diagram of a foldable electronic device 100 according to an embodiment of the present disclosure. Fig. 2 is an overall schematic diagram of the foldable electronic device 100. As shown in fig. 1, the foldable electronic device 100 comprises a foldable display screen 1, an angle sensor 2 and a processor 3.

The angle sensor 2 is used for detecting the folding angle of the foldable display screen 1. The processor 3 is electrically connected with the angle sensor 2 and is used for controlling and switching the application interface displayed on the foldable display screen 1 when the folding angle detected by the angle sensor 2 is determined to be changed and the change value exceeds a preset threshold value.

Therefore, in the application, the foldable display screen 1 is folded, and when the folding angle exceeds the preset threshold value, different application interfaces can be displayed, so that the convenience of display control of the application interfaces is improved.

In some embodiments, the angle sensor 2 detects the folding angle of the foldable display screen 1 at preset time intervals (e.g., 0.5 second, 1 second, etc.) to obtain a plurality of folding angle data, the processor 3 determines that the folding angle detected by the angle sensor 2 has changed when judging that the adjacent obtained folding angles are not equal when receiving the plurality of folding angle data, and the processor 3 determines that the change value of the folding angle exceeds a preset threshold when determining that the difference between the currently obtained folding angle and the folding angle obtained before the time when determining that the folding angle has changed exceeds the preset threshold.

In some embodiments, the foldable display screen 1 is in an initial state when in a flat state, and the folding angle is 0 degree, and the folding angle of the foldable display screen 1 is an angle bent relative to 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 is opposite to the non-display surface S2. The display surface S1 further includes two sub-surfaces, and the non-display surface S2 also includes two sub-surfaces. The folding angle of the foldable display screen is specifically an included angle between two sub-surfaces of the non-display surface S2. The folding angle detected by the angle sensor 2 is correspondingly the included angle between the two sub-surfaces of the non-display surface S2 of the foldable display screen 1. That is, after the foldable display panel 1 is folded, the display surface S1 is located outside and can be viewed at all times. Obviously, in some embodiments, the folding angle of the foldable display screen may also be the included angle between the two sub-surfaces of the display surface S1.

In this application, the foldable display screen 1 may be a main body display structure of the foldable electronic device 100, an outer frame structure of the foldable display screen 1 is the outer frame structure of the foldable electronic device, the non-display surface S2 of the foldable display screen 1 is a 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, the folding of the foldable display screen 1 described in this application is to fold the foldable electronic device 1.

As shown in fig. 2, in some embodiments, the foldable display 1 includes a rotation axis R1, the foldable display 1 includes a first sub-display 11 and a second sub-display 12, the first sub-display 11 is fixedly connected to the rotation axis R1, and the second sub-display 12 is rotatably connected to the rotation axis R1, so that the first sub-display 11 and the second sub-display 12 can rotate around the rotation axis R1 and change the folding angle of the foldable display 1. Fig. 2 is a schematic view only, the rotation axis R1 may include a sleeve and a rotation rod penetrating the sleeve, the first sub-display screen 11 may be fixedly connected to the sleeve, the second sub-display screen 12 is fixedly connected to the rotation rod, and the rotation rod rotates relative to the sleeve, so that the second sub-display screen 12 may be bent/folded relative to the first sub-display screen 11. Of course, the rotation axis is not limited to a physical rotation axis, and may also be a virtual rotation axis, and only the first sub-display screen and the second sub-display screen need to rotate around the rotation axis.

The angle sensor 3 may be a resistive angle sensor, a capacitive angle sensor, a hall angle sensor, etc. disposed on the rotation axis R1, and determines the folding angle by detecting the rotation angle of the rotation axis R1 relative to the second sub-display 12. For example, the rotation angle of the first sub-display 11 and the second sub-display 12 when they are unfolded in parallel is assumed to be zero, i.e. the folding angle is assumed to be zero, and then the rotation angle of the second sub-display 12 when it is rotated relative to the rotation axis R1 is detected 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, and has better color and contrast, and being ultra-thin. The folding line L can be obtained by distributing a plurality of capacitive sensors (not shown) in the foldable display screen 1, and the processor 3 detects the folding angle of the foldable display screen 1 through the angle sensor 2, and can determine the position of the foldable display screen through the voltage variation generated by the capacitive sensors at the bending position of the foldable display screen 1. In another embodiment, a contact point may be provided between the first sub display 11 and the second sub display 12, when the foldable display 1 is in a flat state, the connection between the contact points is broken, and when the foldable display 1 is bent, the connection between the contact points is established, so that the position where the flexible screen is bent may be determined by a change in a path between the contact points to obtain the folding line L.

Thus, 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 obtaining the folding line L, the processor 3 further divides the foldable display screen 1 into a first sub-display 11 and a second sub-display 12 by the folding line L. That is, the processor 3 logically divides the foldable display 1 into a first sub-display 11 and a second sub-display 12 by a folding line L.

In some embodiments, referring to fig. 4, when the foldable display screen 1 is a flexible display screen, the angle sensor 2 may include a plurality of infrared transmitters 21 and a plurality of infrared receivers 22 respectively disposed on four sides of the foldable display screen 1. As shown in fig. 4, each side of the foldable display screen 1 may be provided with a plurality of infrared transmitters 21 and a plurality of infrared receivers 22, the processor 3 may further control the infrared transmitters 21 adjacent to the folding line L to transmit infrared light on the side perpendicular to the folding line L after determining the folding line L, and when the infrared receiver 22 receiving the infrared light changes with the change of the folding angle, the processor 2 may determine the corresponding folding angle according to the infrared receiver 22 receiving the infrared light.

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, the controlling, by the processor 3, the switching of the application interface displayed on the foldable display screen 1 when it is determined that the folding angle detected by the angle sensor 2 changes and the change value exceeds a preset threshold value may include: the processor 3 determines a target application program when it is determined that the folding angle detected by the angle sensor 2 changes and the change value exceeds a preset threshold value; and controlling to switch the application interface of an application program currently displayed on the foldable display screen 1 to the application interface of the target application program.

For example, when the foldable display screen 1 currently displays the application a, which is assumed to be the application interface of the video player, the application a is located in the foreground, and if the foldable electronic device 100 still runs the application B in the background, it is assumed to be WeChat.

So that the foldable display screen 1 can be folded when a user receives a message reminder for a WeChat or wants to go back to the WeChat to view information while watching a video using the video player.

Assuming that the folding angle θ of the foldable display screen 1 is a when a video player is used to watch a video, and after a user folds the foldable display screen 1, the folding angle of the foldable display screen 1 detected by the angle sensor 2 is b, and when the processor 3 determines that | a-b | reaches the set threshold T, the processor controls to switch the application interface of the video player displayed on the foldable display screen 1 to the application interface of the WeChat. That is, the WeChat is switched to the foreground display and is provided for the user, and the video player is switched to the background.

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

Therefore, when the user switches to the application interface of the application program B by increasing the folding angle and needs to return to the application program A after using the application program B, the user folds the device again to enable the folding angle theta to return to the angle a from the angle B, and then the device can be switched to the application program A used before, at the moment, the application program A is located in the foreground, and the application program B is located in the background.

In some embodiments, the processor 3 further determines that any other background application is the target application when determining that the trend of the folding angle detected by the angle sensor 2 is the second trend, or determines that the application with the highest priority is the target application according to the priorities of the other background applications.

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

Wherein the second trend may be an increasing trend. Obviously, in other embodiments, the first trend may be an increasing trend, and the second trend may be a decreasing trend.

Therefore, when the user uses the current application program A, the user needs to check the information in the application program B, the user can fold the foldable display screen 1 by a certain angle, when the change value of the folding angle reaches a preset threshold value, the mobile device is switched to the application interface for displaying the application program B, the user can check the content in the application program B according to the requirement, and after the check is finished, the user can fold the foldable display screen 1 to the previous angle, namely, the application interface of the response application program A is switched. Therefore, the rapid switching operation among different application programs is completed, and the interaction experience of a user for briefly checking recently used other application programs is improved.

In other embodiments, when it is determined 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 screen 1, which may include: the processor 3 determines a target state when it is determined that the folding angle detected by the angle sensor 2 changes and the change value exceeds a preset threshold value; and controlling to switch the application interface of the application program currently displayed on the foldable display screen 1 in a certain state into the application interface in the target state. The switching of the application interfaces comprises switching of the application interfaces of different application programs and switching of the application interfaces of the same application program in different states or between the application interfaces displaying different contents.

For example, when the application program displayed on the foldable display screen is a video player and the current state is the playing state, the processor 3 and the processor 3 determine that the target state is the pause state when it is determined that the folding angle detected by the angle sensor 2 changes and the change value exceeds the preset threshold, and then control to switch the application interface of the video player in the playing state to the application interface in the pause state.

Specifically, when the application a being used by the user is a video player and is watching a video, the value of the folding angle θ of the foldable display screen 1 is set to a, and when the user needs to temporarily leave for some reason, the user needs to pause the playing video, and the foldable display screen 1 can be folded. When the processor 2 detects that the value of the folding angle theta is b and determines that the variation value | a-b | of the folding angle reaches the preset threshold value T, the playing is controlled to be paused, and the application interface is controlled to be switched to the application interface in the paused state.

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

Therefore, when the user switches the application interface of the video player to the application interface in the paused state by increasing the folding angle, and when the user finishes processing other transactions and continues to watch the video, the user can continue to play the paused video by folding the foldable display screen 1 again, so that the folding angle θ returns to the angle a from the angle b.

In some embodiments, the processor 3 further determines that any other state of the application program is the target state when determining that the trend of the change of the folding angle detected by the angle sensor 2 is the second trend, or determines that the state with the highest priority is the target state according to the priority of other states of the application program. When the application program is a video player, other states may further include a fast-forward state, a fast-backward state, and the like, and one state may be randomly entered by folding the foldable display screen 1 by a second trend change of the folding angle.

For example, the application states also have different priorities according to the frequency of use of the user and the like, for example, the state with high frequency of use has a high priority. Specifically, for example, if the playing state and the paused state have higher priority than the fast-forwarding state and the fast-rewinding state, when the processor 3 determines that the trend of the change in the folding angle detected by the angle sensor 2 is the second trend, and determines that the playing state is the target state if the playing state, the fast-forwarding state, and the fast-rewinding state are also present in the states other than the current state.

Wherein the first trend may be a decreasing trend and the second trend may be an increasing trend. Obviously, in other embodiments, the first trend may be an increasing trend, and the second trend may be a decreasing trend.

Therefore, when a user watches a video or plays music by using a video player, sometimes the user needs to leave for processing other things briefly and needs to pause a current program, controls such as pausing and resuming playing can be realized by folding the angle, and the user does not need to click a specific pause/play button for control, so that the convenience of operation is improved, and the user experience is improved.

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

As mentioned above, regardless of the way of the connection of the rotation shaft or the way of the foldable display screen 1 being a flexible display screen, the foldable display screen 1 will form the first sub-display 11 and the second sub-display 12 separated by the folding line L or the rotation shaft during the bending process. Therefore, when the foldable display screen 1 includes the first sub-display 11 and the second sub-display 12 connected by the hinge, the processor 3 may determine the screen areas on both sides of the hinge as the first sub-display 11 and the second sub-display 12. When the foldable display screen 1 is a flexible display screen, the processor 3 may determine, according to the folding line L, that two sides of the folding line L1 are the first sub-display screen 11 and the second sub-display screen 12, respectively.

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

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

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, the plurality of infrared sensors H1 are used for detecting a distance between a human body and the display surface S1, the processor 3 determines, according to the distance detected by the plurality of infrared sensors H1, that the infrared sensor H1 with the smallest detected distance is located on the first sub-display 11 or the second sub-display 12 and is a target sub-display closest to the human body, and controls to display an application interface to be currently displayed on the target sub-display when it is determined that the folding angle detected by the angle sensor 2 is smaller than or equal to a preset angle.

For example, as shown in fig. 5, when the processor 3 determines that the first sub-display 11 is the target sub-display, the application interface of the application a to be currently displayed is controlled to be displayed on the first sub-display 11, and the second sub-display 12 is not displayed, so that energy consumption is reduced.

As shown in fig. 1, the foldable electronic device 100 further includes a memory 4, and the memory 4 may store the aforementioned data such as the preset threshold, the preset angle, and the like for comparing with the variation value of the folding angle.

The preset threshold value and the preset threshold value may be defaulted by a system, or may be generated by subsequent setting of a user.

In some embodiments, the memory 4 further stores program instructions for the processor 3 to call to perform the aforementioned functions.

The memory 4 may include a high-speed random access memory, and may also include a nonvolatile memory, such as a hard disk, a memory, a plug-in hard disk, a Smart Media Card (SMC), a Secure Digital (SD) Card, a Flash memory Card (Flash Card), a plurality of magnetic disk storage devices, a Flash memory device, or other volatile solid state storage devices.

The Processor 3 may be a Central Processing Unit (CPU), other general purpose Processor, a Digital Signal Processor (DSP), an Application Specific Integrated Circuit (ASIC), a Field Programmable Gate Array (FPGA) or other Programmable logic device, discrete gate or transistor logic device, discrete hardware component, etc. A general purpose processor may be a microprocessor or the processor may be any conventional processor or the like, the processor being the control center of the electronic device 100 and various interfaces and lines connecting the various parts of the entire electronic device 100.
