The electronic equipment such as the mobile phone, the tablet personal computer and the like can be used for installing the application, and an application interface corresponding to the installed application is displayed on a display screen of the electronic equipment, so that a user can conveniently use the functions provided by the application. In order to avoid the display screen of the electronic device being too large to affect its convenience, some manufacturers have applied flexible screens to the electronic device, resulting in an electronic device with a folded screen. An electronic device with a folding screen includes at least two display screens and a plurality of cameras on a hardware device. In the prior art, the application interfaces displayed by the same application on the electronic device without the folding screen and the electronic device with the folding screen are the same, so that functions provided for users are the same, and more abundant functions cannot be provided for users according to the characteristics (such as the characteristics of at least two display screens and a plurality of cameras) of the electronic device with the folding screen on a hardware device, and more abundant shooting scenes cannot be provided for users.

In order to solve the above technical problem that an application cannot provide a user with richer functions according to the characteristics of an electronic device with a folding screen on a hardware device, the embodiment of the application provides an application interface display method. When the method is applied to the electronic equipment with the folding screen, the method can provide richer functions for a user according to the characteristics of the electronic equipment with the folding screen on the hardware equipment.

The folding screen of the electronic device is foldable to form at least two screens. For example, the folding screen may be folded along a fold edge or fold axis to form a first screen and a second screen. The folding manner of the folding screen on the electronic device can be divided into two types. One type is an outward folding screen (called outward folding screen for short), and the other type is an inward folding screen (called inward folding screen for short). Wherein, take the example of folding screen can fold and form first screen and second screen. After the outward folding screen is folded, the display direction of the first screen is opposite to the display direction of the second screen. After the inward folding screen is folded, the display direction of the first screen is opposite to the display direction of the second screen.

In this embodiment of the present application, an electronic device having a folding screen is described by taking an inwardly folded folding screen as an example (it can be understood that this embodiment of the present application may also be performed on an electronic device having an outwardly folded folding screen), that is, a display direction of a first screen is opposite to a display direction of a second screen, and a front camera (hereinafter referred to as a first front camera) is disposed on the inwardly folded folding screen. For example, please refer to fig. 1, which illustrates a schematic product form of an electronic device with an invaginated folding screen according to an embodiment of the present application. In fig. 1, (a) is a schematic view of the fully unfolded state of the inward folding screen. The inwardly folded screen may be folded along the fold edges in directions 11a and 11B shown in fig. 1 (a) to form a semi-folded form of the screen a and the screen B shown in fig. 1 (B). After the inward folding screen is folded and divided into an A screen and a B screen, the first front camera can be arranged on the A screen or the B screen. The inward folding screen may follow the folding edge, according to the screen a and the screen B shown in (B) of fig. 1. The inner folding screen may be folded over along the fold edges in the directions 12a and 12b shown in fig. 1 (b) to form the out-turned folding screen in the fully folded configuration shown in fig. 1 (c). As shown in fig. 1 (c), after the in-folded screen of the electronic device is fully folded, the a screen and the B screen are opposite and invisible to the user.

For example, a C screen (i.e., a third screen) may be disposed on the back of the B screen (i.e., the second screen) shown in fig. 1 (B), where the C screen is not shown in fig. 1 (B), and after the folded-in screen is fully folded, the B screen is opposite to the a screen, and the C screen is visible to the user, and the display direction of the C screen is opposite to the shooting direction of the rear camera on the electronic device. It can be appreciated that, for an electronic device with such an invaginated folding screen, when the invaginated folding screen is in a fully folded state, the display direction of the C-screen is consistent with the shooting direction of the rear camera on the electronic device after the invaginated folding screen is in an unfolded state.

In fig. 1, the folding screen of the electronic device is folded longitudinally, that is, the folding screen is folded into left and right screens (i.e., a screen and a screen B screen) according to the longitudinal folding edge on the folding screen.

In this embodiment of the present application, the folded-in folding screen of the electronic device may also be folded laterally, that is, according to a lateral folding edge on the folded-in folding screen, into an upper screen and a lower screen (i.e., an a screen and a B screen). For example, as shown in fig. 2 (a), the folded-in folding screen is in an unfolded state, and is folded along the folding edge in the transverse direction of the folding screen, so that fig. 2 (b) can be formed, and after continuing to fold, fig. 2 (c) can be formed.

It should be noted that, the back side of the folded-in folding screen of the electronic device with the folding screen according to the embodiment of the present application further includes a display screen, which may be referred to as a third screen. The third screen may be disposed on the back of the first screen or the second screen formed by folding the folded-in folded screen, for example, in fig. 2 (C), the back of the B screen (i.e., the second screen) may be provided with a C screen (third screen), which is not shown in fig. 2 (C), the B screen is opposite to the a screen, the C screen is opposite to the B screen, the C screen is visible to the user, and the display direction of the C screen is opposite to the rear camera on the electronic device after the folded-in screen is completely folded.

The display direction of the third screen is opposite to the rear camera on the electronic device when the folded-in folding screen is completely folded, and a front camera (hereinafter referred to as a second front camera) is arranged on the third screen. The electronic device with the folded-in folding screen in the embodiment of the application may include at least three cameras, for example, a first front camera, a second front camera and a rear camera.

In the embodiment of the application, the included angle between the screen A and the screen B of the inward folding screen of the electronic equipment is in the range of [0 degrees, 180 degrees ]. If alpha epsilon [0 degrees, P1], the electronic equipment can determine that the inward folding screen is in a fully folded state (called a folded state for short); if alpha epsilon (P1, P2), the electronic device can determine that the inward folding screen is in a half-folded state (simply called half-folded state); alpha epsilon [ P2, 180 DEG ], the electronic device can determine that the invaginated folding screen is in a fully unfolded configuration (simply referred to as an unfolded configuration). Wherein, 0 DEG is more than 0 DEG and less than P1 and less than 180 DEG is more than P2. P1, P2 may be preset angle thresholds. P1 and P2 can be determined according to the use habit of a large number of users for using the inward folding screen; alternatively, P1, P2 may be set by the user in the electronic device.

In some embodiments, the user may want to use the a-screen and the B-screen as a whole (i.e., as a complete display screen) with a greater angle α than 100 ° according to the usage habits of most users. When the included angle alpha between the A screen and the B screen is smaller than 80 degrees, the user wants to use the C screen independently, the possibility of not using the A screen and the B screen is high, and the inward folding screen can be determined to be in a folded state. When the included angle alpha between the A screen and the B screen is between 80 degrees and 100 degrees, the possibility that the user wants to use the A screen and the B screen is high, and the inward folding screen can be determined to be in a half-folding state.

Therefore, the range of the preset angle threshold P1 in the embodiment of the present application may be (0, 80 ° ], and the range of the preset angle threshold P2 may be [100 °,180 °). For example, the preset angle threshold P1 may be 75 °, and the preset angle threshold P2 may be 105 °. The above examples are merely for the purpose of explaining various embodiments of the present application and are not to be construed as limiting in any way.

It should be noted that, at least two screens formed after the folded or unfolded inner folded screen in the embodiment of the present application may be multiple screens that exist independently, or may be a complete screen with an integral structure, and only folded to form at least two portions.

For example, the inwardly folded screen may be a flexible folding screen including folded edges made of a flexible material. Part or all of the flexible folding screen is made of flexible materials. The at least two panels formed after the flexible folding panel is folded are one complete panel of unitary construction, but folded to form at least two sections.

For another example, the inward folding screen may be a multi-screen folding screen. The multi-screen folding screen may include multiple (two or more) screens. The plurality of screens is a plurality of individual display screens. The plurality of screens may be connected in turn by a folding shaft. Each screen can rotate around a folding shaft connected with the screen, so that the folding of the multi-screen folding screen is realized.

In the following embodiments of the present application, an example in which the folded-in folding screen is a flexible folding screen that can be folded transversely will be described.

By way of example, the electronic device in embodiments of the present application may be a cell phone, tablet, desktop, laptop, handheld, notebook, ultra-mobile personal computer (UMPC), netbook, and electronic device such as a cellular phone, personal digital assistant (personal digital assistant, PDA), artificial intelligence (artificial intelligence, AI) device, wearable device, vehicle-mounted device, smart home device, and/or smart city device.

The pressure sensor 180A is used to sense a pressure signal, and may convert the pressure signal into an electrical signal. In some embodiments, the pressure sensor 180A may be disposed on the display screen 194. The pressure sensor 180A is of various types, such as a resistive pressure sensor, an inductive pressure sensor, a capacitive pressure sensor, and the like. The capacitive pressure sensor may be a capacitive pressure sensor comprising at least two parallel plates with conductive material. The capacitance between the electrodes changes when a force is applied to the pressure sensor 180A. The electronic device 100 determines the strength of the pressure from the change in capacitance. When a touch operation is applied to the display screen 194, the electronic apparatus 100 detects the touch operation intensity according to the pressure sensor 180A. The electronic device 100 may also calculate the location of the touch based on the detection signal of the pressure sensor 180A.

The gyro sensor 180B may be used to determine a motion gesture of the electronic device 100. In some embodiments, the angular velocity of electronic device 100 about three axes (i.e., x, y, and z axes) may be determined by gyro sensor 180B. The gyro sensor 180B may be used for photographing anti-shake. For example, when the shutter is pressed, the gyro sensor 180B detects the shake angle of the electronic device 100, calculates the distance to be compensated by the lens module according to the angle, and makes the lens counteract the shake of the electronic device 100 through the reverse motion, so as to realize anti-shake. The gyro sensor 180B may also be used for navigating, somatosensory game scenes.

In the embodiment of the present application, if the electronic device 100 has an invaginated folding screen and the invaginated folding screen is foldable to form a plurality of screens, a gyro sensor 180B may be included in each screen for measuring the orientation (i.e., the directional vector of the orientation) of the corresponding screen. The electronic device 100 may determine the included angle between adjacent screens based on the measured angular change in the orientation of each screen. For example, as shown in fig. 1 (B), after the folded-in folding screen is folded, a first screen and a second screen are formed, and gyro sensors 180B are disposed in the first screen and the second screen, so that the orientations of the first screen and the second screen can be measured, respectively. The electronic device 100 determines an included angle between the first screen and the second screen according to the measured change of the orientation angle of each screen.

For example, the inward folding screen is folded to form a first screen (a screen shown in fig. 4A) in which a gyro sensor a is provided and a second screen (B screen shown in fig. 4B) in which a gyro sensor B is provided. Here, a simple explanation is made on the principle that the gyro sensor a measures the orientation of the a-screen (i.e., the directional vector of the orientation), the gyro sensor B measures the orientation of the B-screen (i.e., the directional vector of the orientation), and the principle that the electronic apparatus 100 calculates the angle α between the a-screen and the B-screen from the orientation of the a-screen and the orientation of the B-screen.

Wherein the coordinate system of the gyro sensor is a geographical coordinate system. As shown in fig. 4B, the origin O of the geographic coordinate system is located at the carrier (i.e., the point where the device containing the gyroscopic sensor, such as the electronic device 100, is located), the x-axis points to the east (E) along the local meridian, the y-axis points to the north (N) along the local geographic vertical, and the z-axis points to the top along the local geographic vertical, and forms a right-hand rectangular coordinate system with the x-axis and the y-axis.

The electronic device 100 can measure a direction vector of the orientation of each screen in the coordinate system of the gyro sensor provided therein using the gyro sensor 180B provided in each screen. For example, referring to the side view of the electronic device 100 shown in fig. 4A, the electronic device 100 measures that the direction vector of the orientation of the a-screen in the coordinate system of the gyro sensor a is a vector z1, and the direction vector of the orientation of the B-screen in the coordinate system of the gyro sensor B is a vector z2. The electronic device 100 can calculate the angle θ between the vector z1 and the vector z2 according to the vector z1 and the vector z2.

As can be seen from fig. 4A, since the vector z1 is perpendicular to the a-screen and the vector z2 is perpendicular to the B-screen, the included angle α=180° - θ between the a-screen and the B-screen can be obtained. That is, the electronic device 100 can determine the included angle α between the a-screen and the B-screen according to the measured direction vector (i.e., the vector z 1) of the a-screen in the coordinate system of the gyro sensor a and the measured direction vector (i.e., the vector z 2) of the B-screen in the coordinate system of the gyro sensor B.

Although the positions of the gyro sensors provided in the a-screen and the B-screen do not overlap, that is, the origins of the coordinate systems of the gyro sensors of the a-screen and the B-screen do not overlap, the x-axis, the y-axis, and the z-axis of the two coordinate systems are parallel, and thus the coordinate systems of the gyro sensors provided in the a-screen and the B-screen can be considered to be parallel. Thus, although the vector z1 and the vector z2 are not in the same coordinate system, the corresponding axes of the two coordinate systems are in parallel, so the angle θ between the vector z1 and the vector z2 can be calculated by the vector z1 and the vector z 2.

In some embodiments, the angle alpha between the A screen and the B screen can be measured by matching with one or more other sensors.

For example, one acceleration sensor 180E may be provided in each of the inwardly folded screens. The electronic device 100 (e.g., the processor 110) may measure the motion acceleration of each screen as it is rotated using an acceleration sensor; and then calculating the rotating angle of one screen back relative to the other screen according to the measured motion acceleration, namely the included angle alpha between the screen A and the screen B.

In other embodiments, the gyro sensor 180B may be a virtual gyro sensor formed by combining a plurality of other sensors. The virtual gyroscope sensor can be used for calculating the included angle between adjacent screens of the inward folding screen, namely the included angle alpha between the screen A and the screen B.

Android with layered architecture in embodiments of the present application ^TM The system is an example illustrating the software architecture of the electronic device 100. The layered architecture may divide the software into several layers, each layer havingClear roles and division of work. The layers communicate with each other through a software interface. In some embodiments, android will be ^TM The system is divided into four layers, namely an application program layer, an application program framework layer, a system library and a kernel layer from top to bottom.

Referring to fig. 5, fig. 5 is a software architecture block diagram of an electronic device 100 provided by an exemplary embodiment of the present application.

The application layer (which may be abbreviated as application layer) may comprise a series of applications. For example, the application packages may include applications such as lock screens, gallery, calendar, map, desktop, bluetooth, music, text messages, beauty shows, weChat, etc.

The application framework layer provides an application programming interface (Application Programming Interface, API) and programming framework for application programs of the application layer. The application framework layer includes a number of predefined functions. For example, the application framework layer may include an information processing module, a window manager (windowmanager service), a content provider, a view system, a telephony manager, a resource manager, a notification manager, and the like.

The information processing module may be configured to receive an instruction sent by the application layer, and send the received instruction to the system library. The window manager is used for managing window programs. The content provider is used to store and retrieve data and make such data accessible to applications. The data may include video, images, audio, calls made and received, browsing history and bookmarks, phonebooks, etc. The view system includes visual controls, such as controls to display text, controls to display pictures, and the like. The view system includes visual controls, such as controls to display text, controls to display pictures, and the like. The telephony manager is used to provide the communication functions of the electronic device 100. The resource manager provides various resources for the application program, such as localization strings, icons, pictures, layout files, video files, and the like. The notification manager allows the application to display notification information in a status bar.

The window manager can acquire the size of the display screen, judge whether a status bar exists, lock the screen, intercept the screen and the like. Each application run-time Activity, the window manager may create a corresponding application window. The window manager periodically refreshes the display content and window parameters (e.g., size, location, etc. of the application window) in the application window. And, the window manager may create a window state corresponding to each application window. The window manager marks the application window with this and uses this WindowState to store, query and control the state of the application window.

For example, the Window manager may query Window 1 in Window state of Window 1 for whether Window 1 is in full screen state, and if not, the Window manager may query Window 1 in Window state of Window 1 for parameters such as aspect ratio (e.g., 16:9 or 4:3).

The application layer and the application framework layer run in a virtual machine. The virtual machine executes java files of the application program layer and the application program framework layer as binary files. The virtual machine is used for executing the functions of object life cycle management, stack management, thread management, security and exception management, garbage collection and the like.

The system library may include a plurality of functional modules. Such as a device state management system (Device State Manager Service), an angle calculation module, a surface manager (surface manager), a Media library (Media Libraries), a three-dimensional graphics processing library (e.g., openGL ES), a two-dimensional graphics engine (e.g., SGL), etc.

The device state management system may be configured to receive bottom sensor data (e.g., hinge angle data, distance sensor data, etc.) and determine a current device state (e.g., a folded state, a semi-folded state, an unfolded state, etc.) of the electronic device, and may determine whether to use the first screen display or the second screen display according to the device state of the electronic device. The device state management system can determine whether the electronic device has an inward folding screen or not based on the device information of the electronic device, and can also be used for determining the current system display state of the electronic device and switching the system display state of the electronic device. The angle calculation module is used for determining the form of the display screen. The angle calculation module may obtain angle data from a sensor driver of the kernel layer when the electronic device is an electronic device having a folding screen, calculate an opening angle of the folding screen, and determine a form of the folding screen, such as a folded state, a semi-folded state, or an unfolded state, according to the opening angle. The device state management system can inquire the form of the folding screen from the angle calculation module, and can determine the physical folding and unfolding change of the folding screen of the electronic device based on the data transmitted by the angle calculation module. The surface manager is used to manage the display subsystem and provides a fusion of 2D and 3D layers for multiple applications. Media libraries support a variety of commonly used audio, video format playback and recording, still image files, and the like. The three-dimensional graphic processing library is used for realizing three-dimensional graphic drawing, image rendering, synthesis, layer processing and the like. The 2D graphics engine is a drawing engine for 2D drawing.

The kernel layer is a layer between hardware and software. The kernel layer contains at least a display driver, a camera driver, an audio driver, and a sensor driver. A display driver for receiving a notification of the device state management system, the display on the electronic device may be controlled based on the notification of the device state management system, the display including a desktop display, an application interface display, and the like. The sensor drive is used to drive the sensor to detect data. When the acceleration sensor 180E and the gyro sensor 180E detect angle data, a corresponding hardware interrupt is issued to the kernel layer. The sensor driver of the kernel layer sends the angle data to an angle calculation module in the system library, and the angle calculation module is used for calculating the physical form change of the electronic equipment and can be used for determining the physical form change of the inward folding screen of the electronic equipment. The angle calculation module can send the determined physical form change of the inward folding screen of the electronic device to the device state management system, and the device state management system can inform the window manager to change the resolution of the current display screen according to the physical form change of the inward folding screen. For example, when the physical form change of the invaginated folding screen is changed from the semi-folded state to the unfolded state, the device state management system notifies the window manager that the resolution of the current display screen is changed from 1920×1080 to 3840×2160, that is, the effective display area size of the current display screen is changed to 3840×2160. Subsequently, when an application in the application layer calls the window manager to create a corresponding application window, the window manager can set window parameters such as the size, the position and the like of the application window according to the updated screen size, so that the opened application can adapt to the folded screens with different physical forms.

It will be appreciated that the layers and components contained in the layers in the software structure shown in fig. 5 do not constitute a specific limitation on the electronic device. In other embodiments of the present application, the electronic device may include more or fewer layers than shown, and more or fewer components may be included in each layer, as the present application is not limited.

The application layer sends 602 a device type query instruction to the device state management system.

And responding to a first operation of a user on a three-party application in the application layer, and sending a device type query instruction to a device state management system by the three-party application. The equipment state management system is provided with an interface for three-party application to query. Through the interface, the data interaction between the three-party application and the equipment state management system can be realized. If the state management system does not have the interface, the three-party application cannot directly communicate with the state management system. The three-party application can acquire the related information of the electronic equipment through the interface. For example, the three-party application sends a device type query instruction through a query interface preset on the device state management system, and obtains the device type information fed back by the device state management system through the query interface. It can be appreciated that the interaction between the three-party application and the device state management system can be through a query interface preset on the device state management system.

The display information is used for indicating the system display state of the current electronic equipment. The system display state is used to indicate which display screen the electronic device is currently using so that the first screen display indicates that the display is using the first screen and the second screen display indicates that the display is using the second screen.

And 607, the application layer determines whether the system display state of the electronic device is the first screen display according to the second feedback information.

The physical state query instruction is configured to query the physical state of the first screen, where the physical state may include an unfolded state, a semi-folded state, and a folded state, and the relevant description of the physical state of the folded screen may be referred to above, and is not repeated herein. In the embodiments of the present application, the semi-folded state and the folded state may be collectively referred to as a non-unfolded state. The physical state of the first screen may be used as a physical state of the electronic device, for example, when the physical state of the first screen is an expanded state, it is determined that the electronic device is in the expanded state; the electronic device is determined to be in a non-expanded state when the physical state of the first screen is in the non-expanded state.

609, the device state management system sends the third feedback information to the application layer.

It will be appreciated that the positions at which the same elements appear on the first screen and the second screen may differ due to the different display sizes of the first screen and the second screen.

The elements presented by the interface of the second application interface may also differ from the elements presented by the interface of the first application interface.
