DESCRIPTION OF EMBODIMENTS



[0030] A terminal device control method in the embodiments of the present invention is applicable to any terminal device that is equipped with a flexible display. The flexible display may implement a specific degree of flexible folding. For example, the flexible display may be a display apparatus including only a flexible display, or a display apparatus including a combination of a flexible display and a rigid display. Hardness of the rigid display is greater than hardness of the flexible display.

[0031] The following describes the terminal device control method and a terminal device in the embodiments of the present invention with reference to accompanying drawings.

[0032] FIG. 1 is a schematic flowchart of a terminal device control method 100 according to an embodiment of the present invention. The method 100 may be performed by a terminal device, or may be performed by a processor of the terminal device. For ease of description, the following performs description by using an example in which the terminal device is an execution body.

[0033] 110. When a bending behavior of a flexible display occurs, determine a bending parameter of the flexible display.

[0034] Specifically, a user may make one or more bending behaviors of the flexible display by using a physical operation. When the bending behavior of the flexible display occurs, the terminal device determines the bending parameter of the flexible display.

[0035] In this embodiment of the present invention, the bending parameter may include at least one of a bending time parameter, a bending location parameter, a bending direction parameter, and a bending degree parameter. The bending time parameter is used to indicate a time at which the bending behavior of the flexible display occurs, the bending location parameter is used to indicate a location at which the bending behavior of the flexible display occurs, the bending direction parameter is used to indicate a direction in which the bending behavior of the flexible display occurs, and the bending degree parameter is used to indicate a degree of the bending behavior of the flexible display. The bending parameter may be parameters in various forms or various parameters that are used to indicate the bending behavior.

[0036] For example, the bending time parameter may be a recorded time at which the bending behavior of the flexible display occurs, for example, 00:00:00 on January 01, 2017.

[0037] For another example, as shown in FIG. 2, the bending location parameter is described by using a plane rectangular coordinate system. Optionally, the bending location parameter may be represented by using a bending center and/or a bending axis. The bending center is a most convex location or a most concave location on the flexible display when the bending behavior of the flexible display occurs. The bending axis is a waveform curve generated on the flexible display when the bending behavior of the flexible display occurs. In this embodiment of the present invention, a line including points whose curvature is zero on the waveform curve is defined as the bending axis. The bending axis may also be referred to as a bump axis.

[0038] Specifically, when the bending behavior of the flexible display does not occur, coordinates (x, y) are used to indicate locations on the flexible display. When the bending behavior of the flexible display occurs, coordinates corresponding to the most concave location or the most convex location or coordinates corresponding to the most convex location are used as the bending location parameter, for example, (2, 3). Alternatively, a straight line or a curve including points whose curvature is zero is used as the bending location parameter, for example, x = 1, or y = 4x.

[0039] For another example, the bending location parameter of the flexible display may be described with reference to the coordinates of the most concave location or the coordinates of the most convex location and the bending axis.

[0040] It should be noted that each bending behavior of the flexible display has a direction. In one direction, the flexible display is bent towards a display surface, and in another possible direction, the flexible display is bent towards a non-display surface. Bending towards the display surface may also be referred to as inward bending. This indicates that the display surface of the flexible display is in a concave shape. Bending towards the non-display surface may also be referred to as outward bending. This indicates that the display surface of the flexible display is in a convex shape.

[0041] Optionally, in this embodiment of the present invention, the bending direction parameter may be identified by using a numerical value. For example, the bending towards the display surface may be specifically represented by using 0, and the bending towards the non-display surface may be specifically represented by using 1.

[0042] It should be further noted that the bending degree parameter in this embodiment of the present invention is used to indicate a bending degree of the flexible display when the bending behavior of the flexible display occurs, and is used to indicate strength of force currently applied on the flexible display by a user or another device. Optionally, a floating point or an integer value may be used to represent a value of the strength. A larger absolute value of the value indicates a higher degree of bending, for example, 80, 28, 93, or 200.

[0043] It should be understood that the bending parameters in this embodiment of the present invention may be in another form or may be combined with each other for description, provided that the terminal device can identify the bending parameters. This is not specifically limited in this embodiment of the present invention.

[0044] For example, the bending degree parameter and the bending direction parameter may be combined for description. Optionally, a positive number or a negative number may be used to represent a bending direction and a bending degree. For example, -200 indicates that a degree of bending towards the non-display surface is 200, and 101 indicates that a degree of bending towards the display surface is 101.

[0045] An example of a parameter existing when the bending behavior of the flexible display occurs is described above by using the bending location parameter, the bending direction parameter, and the bending degree parameter. This is not specifically limited in this embodiment of the present invention.

[0046] The following describes specific implementations of obtaining the bending parameters.

[0047] In an embodiment, the terminal device is equipped with only the flexible display.

[0048] Optionally, force distribution information of the flexible display is determined, and the bending parameter is determined based on the force distribution information.

[0049] Specifically, the force distribution information is determined by measuring a physical circuit of the flexible display, or the force distribution information is determined by using a force sensor. For example, when it is determined, through measurement by using the force sensor, that a location corresponding to coordinates (2, 3) on the flexible display bears maximum force, and a force value is 20 Newton (N), the bending location parameter of the flexible display is determined as (2, 3), and the bending degree parameter of the flexible display is determined as 20 (N).

[0050] Optionally, capacitance distribution information of the flexible display is determined, and the bending parameter is determined based on the capacitance distribution information. Specifically, in an electronic line or an electric appliance line, capacitance not only exists in a capacitor, but also exists between any two power-on conductors. For example, capacitance exists between power transmission lines, between a transmission line and the ground, between pins of a transistor, and between elements. In this embodiment of the present invention, distribution of the capacitance is referred to as capacitance distribution information. When the bending behavior of the flexible display occurs, capacitance distribution at a bending part is denser, and a capacitance value of the bending part is more regular compared with that of another area. The terminal device determines the bending parameter based on the capacitance distribution information existing when the bending behavior of the flexible display occurs.

[0051] For example, the capacitance value distribution information is determined by using a capacitor. Specifically, according to the information obtained through measurement by using the capacitor, coordinates of a location or an axis at which capacitance value distribution is densest is determined as the bending location parameter.

[0052] For example, when the bending behavior of the flexible display does not occur, a coordinate system of the flexible display is determined by using a center point of the flexible display as an origin, using a horizontal as an x-axis, and using a vertical as a y-axis. When the bending behavior of the flexible display occurs, and the terminal device determines, by using the capacitor, that capacitance value distribution at a location corresponding to x = 4 is densest, the bending location parameter is determined as x = 4.

[0053] In another embodiment, the terminal device is equipped with the flexible display and a rigid display.

[0054] Optionally, a relative location between a first rigid display and a second rigid display is measured by using a first sensor, the flexible display is located between the first rigid display and the second rigid display, and hardness of each rigid display is greater than hardness of the flexible display; and the bending parameter is determined based on the relative location.

[0055] It should be understood that the first sensor may be an optical sensor, or may be a distance sensor. Alternatively, the first sensor may be another sensor that can detect a distance. It should be further understood that the terminal device in this embodiment of the present invention may be equipped with a plurality of rigid displays.

[0056] It should be further understood that the foregoing embodiment of determining the bending parameter is merely an example. This embodiment of the present invention is not limited thereto. For example, the terminal device may alternatively flexibly obtain the bending parameter based on physical implementation of the flexible display.

[0057] 120. Adjust a user interface (User Interface, UI) of the flexible display based on the bending parameter, or generate, based on the bending parameter, a command corresponding to a first application.

[0058] Specifically, the terminal device adjusts the UI of the flexible display based on the bending parameter abstracted from the bending behavior, or generates, based on the bending parameter, the command corresponding to the first application.

[0059] It should be noted that an intelligent operating system such as an Android intelligent operating system performs page rendering and generation based on system resolution, a size of a UI layer, a location of the UI layer, and a resource in the UI layer.

[0060] In an embodiment, when the bending behavior of the flexible display occurs, to ensure UI quality and improve user experience, the bending parameter may be used as one of bases for generating page content.

[0061] In other words, after the user performs the physical operation on the flexible display, the terminal device can adjust the user interface based on the obtained bending parameter.

[0062] For example, when the user bends the display towards the display surface, a display element near a location of the bending axis may be appropriately adjusted, so that the display element has a pantoscopic visual effect similar to that of a curved display, instead of maintaining an original layout of a straight display, where the original layout causes content deformation and extrusion near the bending axis.

[0063] Similarly, after the bending behavior occurs, a sight line of human eyes is not perpendicular to a part of the display, and different displays have different visual angles. Therefore, some intelligent rendering adjustments may be performed, so that the user obtains a natural visual effect regardless of a display location at which the user looks.

[0064] Optionally, in this embodiment of the present invention, if it is determined, based on the bending parameter, that a UI at a first location of the flexible display is in an extruded state or in a stretched state, configuration information of the UI at the first location is adjusted based on a distance parameter. The distance parameter is a distance between the first location and the bending location of the flexible display.

[0065] For example, if it is determined, based on the bending parameter, that content displayed at the bending location is extruded, content closer to the bending axis is extruded severer, and content farther away from the bending axis has greater visual deviation,
assuming that a distance between the first location and the bending axis is d, an adjustment degree of a display element in the configuration information of the UI is inversely proportional to d. An adjustment direction is appropriate dispersion, to compensate for a visual extrusion effect, and implement a better circular-screen visual effect. An adjustment degree of a rendering element in the configuration information of the UI is proportional to d. Angle of view adjustment and degree of inclination adjustment are performed on the rendering element, to implement a better effect. The terminal device may specifically adjust an angle of view and a degree of inclination of the rendering element.

[0066] For example, the adjustment degree of the display element in the configuration information of the UI may be adjusted based on a formula y = -(1/d), where y is the adjustment degree of the display element in the configuration information of the UI, d is the distance between the first location and the bending axis, and a symbol "-" indicates that the adjustment direction is appropriate dispersion.

[0067] From a perspective of the user, the user performs a physical operation of bending the flexible display towards the display surface, in other words, the display surface of the flexible display is relatively bent, displayed content is in the extruded state on the flexible display, content closer to the bending axis is extruded severer, and content farther away from the bending axis has greater visual deviation.

[0068] In this embodiment of the present invention, the physical operation of the user is quantized by using the bending parameter, and the bending parameter is used as a reference for adjusting the configuration information of the UI. Specifically, if the bending location of the flexible display is determined as coordinates (0, 0) of an origin, the coordinates of the origin are used as a center, and an adjustment degree of a display element in the configuration information of the UI at coordinates (x, y) is inversely proportional to a distance between the coordinates (x, y) and the coordinates (0, 0). Therefore, even if the user performs the physical operation of bending the flexible display, the user obtains a natural visual effect regardless of a display location at which the user looks.

[0069] For another example, if it is determined, based on the bending parameter, that content displayed at the bending location is dispersed, content closer to the bending axis is dispersed severer, and content farther away from the bending axis has greater visual deviation,
assuming that a distance between the first location and the bending axis is d, an adjustment degree of a display element in the configuration information of the UI is inversely proportional to d. An adjustment direction is appropriate extrusion, to compensate for a visual dispersion effect, and implement a better circular-screen visual effect. An adjustment degree of a rendering element in the configuration information of the UI is proportional to d, to implement a better effect.

[0070] For example, the adjustment degree of the display element in the configuration information of the UI may be adjusted based on a formula y = +(1/d), where y is the adjustment degree of the display element in the configuration information of the UI, d is the distance between the first location and the bending axis, and a symbol "+" indicates that the adjustment direction is appropriate extrusion.

[0071] Optionally, in this embodiment of the present invention, a first mapping relationship between a plurality of bending parameters and a plurality of UIs may be further established, and the UI is presented based on the bending parameter and the first mapping relationship information.

[0072] For example, the first mapping relationship information includes a correspondence between a plurality of bending direction parameters and a plurality of UIs, and the UI is presented based on the bending direction parameter and the first mapping relationship.

[0073] More specifically, for example, a first UI is presented in a first bending direction, and a second UI is presented in a second bending direction.

[0074] To be specific, if the user performs the physical operation of bending the flexible display towards the display surface, that is, the flexible display presents the first UI, a display element in the first UI is appropriately dispersed. If the user performs a physical operation of bending the flexible display towards the non-display surface, that is, the flexible display presents the second UI, a display element in the second UI is appropriately converged. However, from the perspective of the user, even if the user performs the physical operation of bending the flexible display, the user obtains a natural visual effect regardless of a display location at which the user looks.

[0075] It should be understood that application of intelligently adjusting a UI layout and a visual effect is merely an example description. In the terminal device control method in this embodiment of the present invention, other information in the configuration information of the UI may be further adjusted based on the bending parameter. This is not specifically limited in this embodiment of the present invention.

[0076] In another embodiment, the terminal device may associate the bending parameter with an application command. To be specific, the terminal device may generate, based on the bending parameter, the command corresponding to the first application.

[0077] Optionally, before the command corresponding to the first application is generated based on the bending parameter, the bending parameter is sent to at least one application, where the at least one application includes the first application; and the command corresponding to the first application is generated based on the bending parameter and a second mapping relationship.

[0078] Specifically, the terminal device sends the bending parameter to the at least one application. When the first application in the at least one application receives the bending parameter, the first application can generate a specific operation command based on the second mapping relationship. In other words, in this embodiment of the present invention, the bending behavior of the user is associated with the operation command of the application.

[0079] Optionally, the second mapping relationship includes a correspondence between a plurality of bending parameters and a plurality of applications, and a triggering command of the first application is generated based on the bending parameter and the second mapping relationship information.

[0080] For example, the first application is triggered at a first bending location, and a second application is triggered at a second bending location.

[0081] From the perspective of the user, the terminal device may generate a corresponding specific command based on the bending location parameter of the flexible display. For example, it is assumed that the user performs the physical operation of bending the flexible display towards the display surface, or performs the physical operation of bending the flexible display towards the non-display surface. If the terminal device detects that a location indicated by the bending location parameter is a location of a WeChat icon, a WeChat application is started. If the terminal device detects that the location indicated by the bending location parameter is a location of a QQ icon, a QQ application is started.

[0082] Optionally, the second mapping relationship includes a correspondence between a plurality of bending parameters and a plurality of commands of the first application, and a first command corresponding to the first application is generated based on the bending parameter and the second mapping relationship information.

[0083] In other words, different bending parameters may be corresponding to different operation commands of a same application.

[0084] Optionally, the bending parameter is sent to at least one application, and the at least one application includes the first application, so that the first application generates, based on the bending parameter, the command corresponding to the first application.

[0085] From the perspective of the user, the terminal device may generate a corresponding specific command based on the bending parameter of the flexible display. For example, it is assumed that the user performs the physical operation of bending the flexible display towards the display surface, or performs the physical operation of bending the flexible display towards the non-display surface.

[0086] If a degree of user's force is less than a first threshold, and a detected bending degree parameter is less than 20, the first application is started. If the degree of user's force is greater than the first threshold and less than a second threshold, and the detected bending degree parameter is greater than 20 and less than 30, an application introduction interface of the first application is started. The second threshold is greater than the first threshold. If the degree of user's force is greater than the second threshold, and the detected bending degree parameter is greater than 30, an exit command of the first application is started.

[0087] For example, the first application is a game application. The terminal device may define an elastic input event for a game based on the bending parameter, to improve interest of the game and the application. For example, an elastic behavior of the flexible display may be used to execute a slingshot behavior of the Angry Birds.

[0088] Specifically, the bending degree parameter may be directly used as a bending degree parameter of a slingshot.

[0089] It should be understood that the first application in this embodiment of the present invention may be a game, or may be any other application that is configured with a human computer interaction function related to the flexible display. In other words, the first application may be any application that has a human computer interaction event of the flexible display. This is not specifically limited in this embodiment of the present invention. In addition, for ease of description, the human computer interaction event of the flexible display is referred to as a human computer interaction event for short below.

[0090] An embodiment of the present invention provides a new method that is for a human computer interaction event and that is defined based on a bending behavior of a flexible display, to bring a new operation manner to an application and a game. In addition, a display layout may be more intelligently adjusted by using the behavior, to implement a better visual effect.

[0091] FIG. 3 is a schematic flowchart of a terminal device control method 200 according to an embodiment of the present invention.

[0092] 210. Register a bending behavior event.

[0093] Specifically, an application in a terminal device is registered by using an interface or a method that is for registering a human computer interaction event and that is provided by a system, so that a subsequent human computer interaction event sent by the system may be listened to.

[0094] 220. Listen to a human computer interaction event.

[0095] Specifically, an application that has a human computer interaction function in the terminal device is equipped with a bending behavior listener. The bending behavior listener always listens to a system event that includes a human computer interaction event. After an event of F = FLEXURAL_EVENT is detected through listening, a bending parameter existing when a bending behavior of a flexible display occurs is obtained through parsing.

[0096] 230. Determine a bending parameter when a bending behavior occurs.

[0097] Specifically, a user bends the terminal device of the flexible display. To avoid repetition, details are not described herein again.

[0098] 240. Generate the human computer interaction event based on the bending parameter.

[0099] Specifically, after the physical bending behavior of the flexible display is converted into a digital parameter, a format conversion is further performed, to be specific, the bending parameter is converted into a parameter in a data format of the human computer interaction event. Optionally, the following format is used:

[Event flag type F: Parameter P]



[0100] The event flag type F represents a flag for differentiating the event from another event (for example, a touch event, or an incoming call event) of the system. The flag is a system-level flag. For any application that obtains an event sent by the system, the application may determine, by using the event flag type F, whether the event is the human computer interaction event of the flexible display. In this embodiment of the present invention, F = FLEXURAL EVENT is used as an example for description. Definition of the flag is not limited to this name. The parameter P represents a parameter carried in the human computer interaction event, and is a data structure.

[0101] For example, the parameter P may specifically include the following information:

[A quantity N of bending behaviors,

a bending behavior ID1, a time at which the bending behavior 1 occurs, a bending axis location of the bending behavior 1, a bending degree of the bending behavior 1, and information about another extension standby field of the bending behavior 1;

a bending behavior ID2, a time at which the bending behavior 2 occurs, a bending axis location of the bending behavior 2, a bending degree of the bending behavior 2, and information about another extension standby field of the bending behavior 2;

a bending behavior IDN, a time at which the bending behavior N occurs, a bending axis location of the bending behavior N, a bending degree of the bending behavior N, and information about another extension standby field of the bending behavior N.]



[0102] The quantity N of bending behaviors indicates a quantity of bending behaviors on the flexible display in a current state. Each bending behavior includes information such as an ID of the bending behavior, a time at which the bending behavior occurs, a location of the bending behavior, and a degree of the bending behavior. The field "information about another extension standby field of a bending behavior i" is an extension field, which allows the system to retain an extension capability. A plurality of extension fields may be set for technology evolution.

[0103] It should be understood that the data format and the parameter P of the human computer interaction event are merely examples. This is not specifically limited in this embodiment of the present invention.

[0104] 250. Add a human computer interaction event to a system event or a message queue.

[0105] Specifically, after the human computer interaction event is generated, the terminal device adds the human computer interaction event to the system message queue, so that the human computer interaction event joins the message sending queue. Optionally, the queue complies with an original priority or queuing rule of the system.

[0106] 260. Send the system event or the message queue to at least one application.

[0107] Specifically, when it is the turn of the human computer interaction event to be sent in the queue, the human computer interaction event may be sent by using a system event sending mechanism. Optionally, the human computer interaction event is sent in a broadcast manner. Specifically, the terminal device searches for all applications registered for listening to a human computer interaction event, and broadcasts the human computer interaction event (including a parameter) to the applications.

[0108] 270. Generate, based on the human computer interaction event, a command corresponding to a first application.

[0109] Specifically, after data is obtained through parsing, the application processes the data based on a requirement of the application. To avoid repetition, details are not described herein again.
