Detailed Description

The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application. The terminology used in the following examples is for the purpose of describing particular embodiments only and is not intended to be limiting of the application. As used in the specification of the application and the appended claims, the singular forms "a," "an," "the," and "the" are intended to include, for example, "one or more" such forms of expression, unless the context clearly indicates to the contrary. It should also be understood that in embodiments of the present application, "one or more" means one, two, or more than two; "and/or", describes an association relationship of the association object, indicating that three relationships may exist; for example, a and/or B may represent: a alone, a and B together, and B alone, wherein A, B may be singular or plural. The character "/" generally indicates that the context-dependent object is an "or" relationship.

Reference in the specification to "one embodiment" or "some embodiments" or the like means that a particular feature, structure, or characteristic described in connection with the embodiment is included in one or more embodiments of the application. Thus, appearances of the phrases "in one embodiment," "in some embodiments," "in other embodiments," and the like in the specification are not necessarily all referring to the same embodiment, but mean "one or more but not all embodiments" unless expressly specified otherwise. The terms "comprising," "including," "having," and variations thereof mean "including but not limited to," unless expressly specified otherwise.

The plurality of the embodiments of the present application is greater than or equal to two. It should be noted that, in the description of the embodiments of the present application, the terms "first," "second," and the like are used for distinguishing between the descriptions and not necessarily for indicating or implying a relative importance, or alternatively, for indicating or implying a sequential order.

With the continuous development of flexible display technology, the form of the display screen of the electronic device has changed greatly, and the folded screen becomes an emerging form of display screen and is applied to a plurality of electronic devices such as mobile phones. Currently, in order to provide a more convenient viewing experience for users, dual-folding-screen electronic devices having an inner screen and an outer screen at the same time are gradually becoming a development direction of future electronic devices. For a folding screen terminal, the terminal has two forms of a folded state and an unfolded state.

Specifically, the folded state refers to a state when the opening and closing angle of the electronic device is 0 degrees or close to 0 degrees. In the folded state, the inner screen (i.e., the second display screen) of the electronic device is closed inward and cannot be directly seen by a user, and the electronic device provides a display function for the user through the outer screen (i.e., the first display screen). When a user does not need to use the electronic equipment, the folding screen electronic equipment can be in a folded state, so that the volume of the electronic equipment is reduced, and the electronic equipment is convenient for the user to carry.

The unfolded state refers to a state in which the opening and closing angle of the electronic device is 180 degrees or close to 180 degrees. In this unfolded state, the inner screen (i.e. the second display screen) of the electronic device is flattened, presented to the user as one appearance of the electronic device, through which the electronic device provides display functionality to the user, while the outer screen (i.e. the first display screen) of the electronic device typically displays a black screen. When a user needs to use the screen of the electronic equipment to perform operations such as reading and entertainment, the folding screen can be in an unfolded state, so that the area of a display interface is increased, and more comfortable use experience is provided for the user.

It should be noted that, between the folded state and the unfolded state, a semi-folded state may also be included. The half-folded state refers to a state in which the opening and closing angle of the electronic device tends to be between 0 degrees and 180 degrees. When the electronic device is in a semi-folded state, the display screen of the electronic device for providing the display function for the user can be an external screen or an internal screen.

In some examples, the electronic device may provide a display function to a user through the external screen with a fold angle less than 45 degrees. In other examples, where the fold angle is greater than 90 degrees, the electronic device may provide display functionality, etc., to the user through the inner screen.

That is, the process of switching the folding-screen electronic device from the unfolded state to the folded state is the process of switching from using the inner screen to using the outer screen. Similarly, the process of switching the folding-screen electronic device from the folded state to the unfolded state is the process of switching from using the outer screen to using the inner screen.

However, when switching from using the external screen to using the internal screen, or from using the internal screen to using the external screen, the content displayed by the external screen cannot be linked with the content displayed by the internal screen, resulting in lower interest for the user.

In view of the above, the present application provides a method, an apparatus, and a medium for displaying a screen-locked image in a first display frame of a first display screen when the first display screen of an electronic device is in a screen-locked state and the electronic device is in a folded state; and responding to the unfolding operation of the user on the electronic equipment, displaying the screen locking image in a second display frame of the second display screen, and enabling the second display frame to move towards the center of the second display screen, wherein the position of the first display frame on the first display screen corresponds to the starting position of the second display frame on the second display screen. Therefore, when the external screen is switched to the internal screen, or the internal screen is switched to the external screen, the content displayed by the external screen and the content displayed by the internal screen are coordinated, so that the interest of the user is enhanced.

It should be noted that the above description of the inner screen and the outer screen is merely an example, and does not constitute a specific limitation on the foldable electronic device according to the embodiment of the present application. For example, the inner screen of the folding screen electronic device may be formed by splicing two or more non-folding screens, and/or the outer screen may be a folding screen or the like.

For ease of understanding, the following will take the inner screen (second display screen) as a folding screen, and the foldable electronic device is further provided with an outer screen (first display screen) as an example.

For example, a set of sensors (one gyro sensor and one acceleration sensor) is provided on the outer screen of the electronic device 100, and a set of sensors is also provided on the inner screen of the electronic device 100. Then, the electronic device 100 combines the data collected by the gyroscope sensors on the inner and outer screens and the data collected by the acceleration sensor to determine the folding angle of the inner screen of the electronic device 100.

Specifically, the electronic device 100 may obtain three-axis (X-axis, Y-axis, Z-axis) data (in m/s2, sampling frequency of 100 Hz) of the electronic device 100 in the camera coordinate system and three-axis data (in rad/d, sampling frequency of 100 Hz) of the gyro sensor after the zero offset correction through the acceleration sensor. Then, the electronic device 100 may extract the value of the acceleration sensor (with the unit of m/s2 and the sampling frequency of 100 Hz) and the system time (or timestamp) corresponding to the data from the triaxial data of the acceleration sensor of the external screen through a filtering algorithm, and then calculate by using these parameters through a further fusion algorithm to obtain the opening and closing angles of the two screens of the internal screen and the external screen.

In some embodiments, the Android system is divided into four layers, from top to bottom, an application layer (APP), a Framework layer (FWK), a An Zhuoyun row (Android running time), and a system library and Kernel layer (Kernel), respectively.

The application layer may include a series of application packages. In some embodiments, the application layer may include cell phone wallpaper, one-touch screen, and the like applications. In some examples, the wallpaper application may implement the display of wallpaper or transition animation in embodiments of the application. For example, a cell phone wallpaper application may provide a user interface to enable a user to change wallpaper or video displayed by a transition animation.

The framework layer provides an Application Programming Interface (API) and programming framework for the application of the application layer, where some predefined functions may be included. The hardware abstraction layer defines a hardware 'driving' interface, so that the coupling degree between the android operating system and the hardware is reduced. Illustratively, the framework layer may include a window manager, a content provider, a view system, and the like.

Specifically, the window manager is used for managing the window program. 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.

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 may be used to build applications. The display interface may be composed of one or more views. For example, a display interface including a text message notification icon may include a view displaying text and a view displaying a picture.

AndroidRuntime includes a core library and virtual machines. Android system is responsible for scheduling and management of android systems. The core library consists of two parts: one part is a function which needs to be called by java language, and the other part is a core library of android. 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. For example: surface manager (surfacemanager), media Libraries (Media Libraries), three-dimensional graphics processing Libraries (e.g., openGLES), 2D graphics engines (e.g., SGL), etc.

In particular, 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 media library may support a variety of audio and video encoding formats, such as MPEG4, h.264, MP3, AAC, AMR, JPG, PNG, etc. 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 display driver, sensor driver, etc. In some examples, the kernel layer may further include an angle matching module coupled to the angle sensor 160D to learn the opening and closing angle of the electronic device.

It is to be appreciated that the components contained in the system framework layer, the system library, and the runtime layer shown in fig. 2 do not constitute a particular limitation of the electronic device 100. In other embodiments of the application, electronic device 100 may include more or fewer components than shown, or certain components may be combined, or certain components may be split, or different arrangements of components.

Although the Android system is described as an example in the embodiment of the present application, the basic principle is equally applicable to the electronic device 100 based on the os, windows, and other operating systems.

Illustratively, the landscape folding screen electronic apparatus 100 includes: the inner screen 11, the outer screen 21, the power key 31, the first body 41, and the second body 51.

Referring to fig. 5, the flowchart of a collaborative display method according to an embodiment of the present application is shown. The method is applied to the electronic equipment, and the electronic equipment can be a mobile phone, a computer or a tablet personal computer and the like, so long as the electronic equipment comprises an inner screen (a second display screen) and an outer screen (a first display screen).

S501: and when the first display screen of the electronic equipment is in a screen locking state and the electronic equipment is in a folding state, displaying a screen locking image in a first display frame of the first display screen.

The screen locking state is a state when the screen of the electronic device is locked. The folded state refers to a state when the opening and closing angle of the electronic device is 0 degrees or close to 0 degrees.

For example, the user may perform operations such as touching or pressing a button on the electronic device in the off-screen state, that is, the electronic device may enter the lock-screen state. After the screen is locked by the screen locking mode of the electronic equipment, the user can enter the desktop mode after unlocking is completed in an unlocking mode such as fingerprint, password, voiceprint and the like.

In some specific implementations, the method for determining whether the electronic device is in a folded state may include the following steps:

the first method is as follows: distance sensors 160A may be respectively disposed at the leftmost end and the rightmost end of the electronic device, and whether the electronic device is in a folded state may be determined based on the distance value obtained by the distance sensor 160A. If the distance value obtained by the distance sensor 160A is 0 or very close to 0, it may be determined that the electronic device is in a folded state.

The second method is as follows: an ambient light sensor 160C may be disposed at an internal screen of the electronic device, and whether the electronic device is in a folded state may be determined based on an ambient light value acquired by the ambient light sensor 160C. If the ambient light value acquired by ambient light sensor 160C is 0 or very close to 0, then the electronic device may be determined to be in a folded state.

The third method is as follows: the angle sensor 160D may be provided at an inner screen and an outer screen of the electronic device, respectively. The angle sensor 160D may include an acceleration sensor, a gyroscope sensor, and the like, and obtains an opening and closing angle of the electronic device by combining values acquired by the gyroscope sensor and the acceleration sensor on the inner screen and the outer screen, so as to determine whether the electronic device is in a folded state. If the opening and closing angle is 0 degree or very close to 0 degree, the electronic equipment can be judged to be in a folded state.

It should be noted that, the method for determining whether the electronic device is in the folded state is not limited in the present application.

When the outer screen of the electronic equipment is in a screen locking state and the electronic equipment is in a folding state, a screen locking image can be displayed in a first display frame of the outer screen. For example, referring to fig. 6A and fig. 7A, fig. 6A is a schematic view of an opening and closing angle of 0 degrees of a transverse folding screen provided by an embodiment of the present application, and fig. 7A is a schematic view of an opening and closing angle of 0 degrees of a longitudinal folding screen provided by an embodiment of the present application. The opening and closing angle is 0 degree, which means that the electronic equipment is in a folded state, at the moment, the outer screen is in a bright screen state, the inner screen is in a screen-off state, and as shown in two figures, a screen locking image of a square block is displayed in a first display frame of the outer screen.

The first display frame may be a display portion of the entire external screen, or may be a display frame of any size in the external screen, and the size and position of the first display frame are not limited in the present application.

It is understood that the lock screen image may be a still image or a moving image. If the screen locking image is a dynamic image, when the external screen of the electronic device is in a screen locking state and the electronic device is in a folding state, displaying an initial image frame of the dynamic image in a first display frame of the external screen.

S502: and responding to the unfolding operation of the user on the electronic equipment, and displaying the screen locking image in a second display frame of the second display screen.

After the user performs the unfolding operation on the electronic device, the electronic device can acquire the unfolding angle (namely the opening and closing angle) of the user on the electronic device, and judge whether to display the screen locking image in the second display frame of the inner screen or continuously keep the inner screen in the screen-off state according to the opening and closing angle.

In some specific implementations, an angle sensor 160D may be connected to a wallpaper apk (Android application package) of the electronic device, and an opening and closing angle of the internal screen may be obtained through the angle sensor 160D. After the mobile phone wallpaper apk is connected with the angle sensor 160D, once the opening and closing angle of the electronic device is changed, the opening and closing angle uploaded by the angle sensor 160D can be read by the mobile phone wallpaper apk, that is, the mobile phone wallpaper apk can monitor the electronic device at any time so as to obtain the opening and closing angle of the electronic device.

Specifically, the electronic device may collect three-axis (X-axis, Y-axis, Z-axis) data (in m/s) of the electronic device in the camera coordinate system through the acceleration sensor of the angle sensor 160D ² ) Triaxial data (in rad/d) of the gyro sensor after zero offset correction. The electronic device can then calculate the triaxial number of the acceleration sensor of the external screen through a filtering algorithmAnd extracting the value (unit is m/s 2) of the acceleration sensor and the system time (or time stamp) corresponding to the data from the data, and then calculating by using the parameters through a further fusion algorithm to obtain the opening and closing angle of the electronic equipment. It is understood that the sampling frequency may be 100Hz, or may be 50Hz, 200Hz, etc., and the present application is not limited to the specific sampling frequency.

When the electronic device receives the unfolding operation of the user on the electronic device, it is required to first judge whether the opening and closing angle is greater than an angle threshold. Only after the opening and closing angle reaches the angle threshold, the electronic equipment can display a screen locking image in a second display frame of the inner screen, and the outer screen of the electronic equipment is in a screen-off state at the moment; when the opening and closing angle does not reach the angle threshold value, the inner screen of the electronic equipment cannot display the screen locking image, and is in a screen extinguishing state, and still is an outer screen for displaying the screen locking image.

In some specific implementations, the angle threshold may be 45 degrees, that is, the opening angle is greater than or equal to 45 degrees, and the lock screen image may be displayed in the second display frame of the inner screen. It should be noted that, the angle threshold may be set by a person skilled in the art when developing the electronic device, or may be set by a user according to personal habits in actual use, and the angle threshold may also be 40 degrees, 50 degrees, or the like, and the present application is not limited to the specific size and setting manner of the angle threshold.

In some examples, reference may be made to fig. 6B and fig. 7B, where fig. 6B is a schematic view of an opening angle of a transverse folding screen being smaller than 45 degrees, and fig. 7B is a schematic view of an opening angle of a longitudinal folding screen being smaller than 45 degrees, provided in an embodiment of the present application. At this time, the opening and closing angle of the electronic device does not reach the angle threshold value of 45 degrees, so the electronic device still displays the display function to the user through the external screen.

Referring to fig. 6C and fig. 7C, fig. 6C is a schematic diagram of an opening and closing angle of a transverse folding screen greater than 45 degrees according to an embodiment of the present application, and fig. 7C is a schematic diagram of an opening and closing angle of a longitudinal folding screen greater than 45 degrees according to an embodiment of the present application. At this time, since the opening and closing angle of the electronic device has reached the angle threshold value of 45 degrees, the electronic device changes to display the display function to the user through the inner screen, and at this time, the screen locking image of the square starts to be displayed in the second display frame of the inner screen.

It will be appreciated that the position of the second display frame on the inner screen corresponds to the position of the first display frame on the outer screen. For example, if the first display frame is located at the middle of the outer screen, the second display frame is located at the middle of the inner screen on the first body. The positions of the specific first display frame and the specific second display frame are not limited by the present application.

It can be understood that if the lock screen image is a dynamic image, when the internal screen of the electronic device is in a bright screen state, that is, when the opening and closing angle of the electronic device reaches the angle threshold, the initial image frame of the dynamic image is displayed in the second display frame of the internal screen, that is, the initial image frame is the same as the image frame displayed in the first display frame of the external screen.

S503: and moving the second display frame to the center of the second display screen based on the unfolding angle of the electronic equipment.

According to the increase of the opening and closing angle obtained by the electronic equipment, the second display frame gradually moves towards the center direction of the inner screen.

In some examples, referring to fig. 6D, fig. 6E, and fig. 6F, fig. 6D is a schematic view of an opening angle of 45 degrees to 90 degrees of a transverse folding screen according to an embodiment of the present application; fig. 6E is a schematic diagram of an opening/closing angle of 90 degrees of a transverse folding screen according to an embodiment of the present application; fig. 6F is a schematic diagram of an opening/closing angle of 180 degrees of a transverse folding screen according to an embodiment of the present application.

When the opening and closing angle of the electronic equipment reaches an angle threshold value, after the screen locking image is displayed in the second display frame of the inner screen, the second display frame gradually moves rightwards along with the increase of the opening and closing angle of the electronic equipment until the opening and closing angle reaches 180 degrees or is very close to 180 degrees, namely, when the electronic equipment presents an unfolding state, the second display frame moves to the center position of the inner screen.

In other examples, reference may be made to fig. 7D, fig. 7E, and fig. 7F, where fig. 7D is a schematic view of an opening angle of 45 degrees to 90 degrees of a longitudinal folding screen according to an embodiment of the present disclosure; fig. 7E is a schematic diagram of an opening/closing angle of 90 degrees of a longitudinal folding screen according to an embodiment of the present application; fig. 7F is a schematic diagram of an opening and closing angle of 180 degrees of a longitudinal folding screen according to an embodiment of the present application.

When the opening and closing angle of the electronic equipment reaches an angle threshold value, after the screen locking image is displayed in the second display frame of the inner screen, the second display frame gradually moves downwards along with the increase of the opening and closing angle of the electronic equipment until the opening and closing angle reaches 180 degrees or is very close to 180 degrees, namely, when the electronic equipment presents an unfolding state, the second display frame moves to the center position of the inner screen.

In some specific implementations, the speed at which the second display frame moves toward the center of the inner screen may be directly related to the speed at which the user expands the electronic device, and the present application is not limited to the specific speed of movement.

It can be understood that if the lock screen image is a dynamic image, when the opening and closing angle of the electronic device exceeds the angle threshold, the second display frame of the inner screen displays other image frames except the initial image frame of the dynamic image, that is, the electronic device will display and play the dynamic image as the lock screen image.

In some specific implementations, the lock screen image is a final effect rendered using software of OpenGL, engine rendering, and the like. In particular, openGL (opengraphics library) is a cross-language, cross-platform Application Programming Interface (API) for rendering 2D, 3D vector graphics. The present application is not limited to specific rendering software.

S504: when the second display frame reaches the center of the second display screen, the screen locking image in the second display frame is the screen locking wallpaper of the electronic equipment.

Referring to fig. 6F and fig. 7F, when the second display frame reaches the center of the inner screen, the screen locking image in the second display frame is the screen locking image of the electronic device, and at this time, the electronic device is still in the screen locking state, and the user can enter the desktop mode only after unlocking is completed in an unlocking mode such as fingerprint, password, voiceprint and the like.

Specifically, the desktop mode is a mode after the electronic device is unlocked. For example, a user may operate the electronic device in a desktop mode to use the corresponding functionality provided by the electronic device. For example, the user may use a chat application, a video application, or the like.

It can be understood that if the lock screen image is a dynamic image, when the electronic device is in the unfolded state, the second display frame of the inner screen displays the last image frame of the dynamic image. That is, the electronic device displays and plays the moving image as a lock screen wall paper in the process from the opening and closing angle reaching the angle threshold value until the opening and closing angle reaches 180 degrees or very close to 180 degrees.

It should be noted that, the collaborative display method provided by the embodiment of the present application may be applied not only to a process of switching the electronic device with a folding screen from a folded state to an unfolded state, that is, a process of switching the electronic device with an outer screen to an inner screen, but also to a process of switching the electronic device with a folding screen from an unfolded state to a folded state, that is, a process of switching the electronic device with an inner screen to an outer screen, as described above. The present application is not limited to the unfolding or folding of the folding screen.

The application provides a collaborative display method, which comprises the steps that when a first display screen of electronic equipment is in a screen locking state and the electronic equipment is in a folding state, screen locking images are displayed in a first display frame of the first display screen; and responding to the unfolding operation of the user on the electronic equipment, displaying the screen locking image in a second display frame of the second display screen, enabling the second display frame to move towards the center of the second display screen, and when the second display frame reaches the center of the second display screen, obtaining the screen locking image in the second display frame as the screen locking wallpaper of the electronic equipment. The position of the first display frame on the first display screen corresponds to the starting position of the second display frame on the second display screen. Therefore, when the external screen is switched to the internal screen, or the internal screen is switched to the external screen, the content displayed by the external screen and the content displayed by the internal screen are coordinated, so that the interest of the user is enhanced.

Referring to fig. 8, a flowchart of another collaborative display method according to an embodiment of the present application is shown. It should be noted that the steps of S801 to S803 are the same as the steps of S501 to S503, and will not be described here again. The method comprises the following steps:

s801: and when the first display screen of the electronic equipment is in a screen locking state and the electronic equipment is in a folding state, displaying a screen locking image in a first display frame of the first display screen.

S802: and responding to the unfolding operation of the user on the electronic equipment, and displaying the screen locking image in a second display frame of the second display screen.

S803: and moving the second display frame to the center of the second display screen based on the unfolding angle of the electronic equipment.

S804: when the second display frame reaches the center of the second display screen, the screen locking image in the second display frame is the desktop wallpaper of the electronic equipment.

Referring to fig. 9, a schematic diagram of an electronic device with an unfolded and folded screen according to an embodiment of the present application is shown. When the electronic device is unfolded to 180 degrees or very close to 180 degrees, i.e. the electronic device is in an unfolded state, the second display frame reaches the center of the inner screen. And when the second display frame reaches the center of the inner screen, the screen locking image in the second display frame is the wallpaper image of the electronic equipment. That is, at this point the electronic device has been unlocked into desktop mode. Specifically, the desktop mode is a mode after the electronic device is unlocked. For example, a user may operate the electronic device in a desktop mode to use the corresponding functionality provided by the electronic device. For example, the user may use a chat application, a video application, or the like.

It can be understood that if the lock screen image is a dynamic image, when the electronic device is in the unfolded state, the second display frame of the inner screen displays an end image frame of the dynamic image, that is, the wallpaper image of the electronic device is the end image frame of the dynamic image.

It can be understood that dynamic processing such as size, blurring, deformation and the like can be performed on the screen locking image, and the processed image can be used as desktop wallpaper of the electronic equipment.

The application provides a collaborative display method, which comprises the steps that when a first display screen of electronic equipment is in a screen locking state and the electronic equipment is in a folding state, screen locking images are displayed in a first display frame of the first display screen; and responding to the unfolding operation of the user on the electronic equipment, displaying a screen locking image in a second display frame of the second display screen, enabling the second display frame to move towards the center of the second display screen, and when the second display frame reaches the center of the second display screen, obtaining the screen locking image in the second display frame as desktop wallpaper of the electronic equipment, wherein the position of the first display frame on the first display screen corresponds to the initial position of the second display frame on the second display screen. Therefore, when the external screen is switched to the internal screen, or the internal screen is switched to the external screen, the content displayed by the external screen and the content displayed by the internal screen are coordinated, so that the interest of the user is enhanced.
