It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0024] It should be noted that, if there is no conflict, the various features in the embodiments of the present invention can be combined with each other, and all are within the scope of protection of the present invention. In addition, although the functional modules are divided in the device schematic diagram and the logical order is shown in the flow chart, in some cases, the steps shown or described can be performed in a different order from the module division in the device or the flow chart. Furthermore, the words "first", "second", "third", etc. used in the present invention do not limit the data and execution order, but only distinguish the same items or similar items with basically the same functions and effects.

[0025] To describe the present application in more detail, a wallpaper display system involved in the present application is first introduced. The wallpaper display system is a multi-screen display system, which is a system that expands the display area by connecting multiple display screens. The system allows users to combine multiple display screens into a unified display space, increase the available work area, improve work efficiency, and provide a richer multimedia experience.

[0026] See also Figure 2 , is a schematic diagram of the architecture of a wallpaper display system provided in an embodiment of the present application, Figure 2 The wallpaper display system 10 shown may include a computer device 101 and at least one external display screen 102. The computer device 101 may be a device that supports an external display device, such as a laptop, a tablet computer, or a desktop computer. The computer device 101 may be configured with a preset operating system, which may be an Android system. The external display screen 102 may be an independent display device, or may be a display configured on a computer, a display screen of a television, or the like.

[0027] In one embodiment, the screen mode of the external display screen 102 may include an extended screen and a duplicate screen. The extended display refers to a configuration mode that uses multiple display screens to expand the display area. It allows the display space of the computer device to be expanded to multiple external display screens to improve work efficiency and multi-tasking capabilities. Through the extended screen, the user can perform tasks on one screen and display related information, documents, charts, media content, etc. on another screen, which is particularly suitable for tasks such as viewing multiple applications at the same time, editing large documents, processing graphics or video editing, etc. The duplicate screen (Duplicate Display) can also be called a mirror screen or a clone screen. In this duplicate screen mode, all connected display screens will display the same content as the main screen, just like a screen is mirrored to other screens. The duplicate screen mode can be generally used for demonstrations, displays, training, or sharing content in a conference room. As a feasible implementation method, the user can configure the external display screen to a duplicate screen mode through the display settings of the operating system of the computer device 101 or the graphics card driver.

[0028] In a feasible implementation, the graphics card interface (such as HDMI, DisplayPort, DVI, etc.) of the computer device 101 can be used to connect the external display screen 102, and the user can arrange the external display screen 102 in a desired direction to form a continuous display space. Alternatively, a dedicated hardware device, such as a video splitter or a video wall controller, can be used, which can combine multiple displays into a large display screen.

[0029] Through the wallpaper display system 10, the wallpaper display method provided in the present application can be implemented to achieve the tiling effect of the same wallpaper on multiple screens to achieve visual continuity. For example, the display effect can be as follows: Figure 3 As shown, Figure 3 The wallpaper A shown is the same wallpaper, and each screen displays part of the wallpaper A, so that the wallpaper A is tiled on multiple screens, so that the user can determine that the multiple screens are currently connected to the same computer device, thereby enhancing the user experience.

[0030] based on Figure 2 The wallpaper display system shown in the figure, the wallpaper display method involved in this application is described in detail below. Figure 4 , is a flowchart of a wallpaper display method provided in an embodiment of the present application. The wallpaper display method shown in the present application is applied to a computer device, and the computer device is connected to at least one external display screen. The method may include the following steps;

[0031] S401: Acquire a wallpaper resource of a main screen of a computer device, and determine a wallpaper type according to the wallpaper resource.

[0032] In one embodiment, before obtaining the wallpaper resource of the main screen of the computer device and determining the wallpaper type according to the wallpaper resource, it also includes: monitoring whether the wallpaper of the main screen of the computer device and / or the external display screen changes; if so, obtaining the wallpaper resource of the main screen of the computer device and determining the wallpaper type according to the wallpaper resource.

[0033] It should be noted that the computer device can monitor in real time whether the wallpaper of its main screen and / or the external display screen has changed. If there is a change, the above step S401 can be executed. If there is no change, the above monitoring mode can be maintained continuously.

[0034] In one embodiment, monitoring whether the wallpaper of the main screen of the computer device and / or the external display screen changes includes: monitoring whether an instruction to change the wallpaper is received, and / or whether the external display screen is increased or decreased.

[0035] For example, a user can manually change the wallpaper through the user interaction interface of the computer device. The wallpaper may include the lock screen wallpaper, the main screen wallpaper, etc. Once the user performs the change operation, the computer device may receive the instruction to change the wallpaper and execute the step S401. Alternatively, the user can also set a wallpaper combination and set a preset change time interval. The computer device can automatically change the wallpaper in the wallpaper combination according to the preset change time interval. Each time it is changed, the computer device can be considered to have received the instruction to change the wallpaper and execute the step S401.

[0036] For another example, the user can increase or decrease the number of external display screens according to their needs. For example, the current number of connected display screens is 2, and the user adds an external display screen to the computer device. The computer device detects the user's operation of adding the external display screen and executes step S401.

[0037] In one embodiment, the wallpaper type includes a dynamic wallpaper type and a static wallpaper type. The dynamic wallpaper type refers to a wallpaper that is in the form of animation, and some dynamic wallpapers can respond to user operations; the static wallpaper type refers to a wallpaper that is a picture, and a static wallpaper can be regarded as a special dynamic wallpaper.

[0038] As a feasible implementation, in the Android system, both dynamic wallpaper and static wallpaper can run in the system background as a Service and draw content on a window of type TYPE_WALLPAPER. Static wallpaper can be processed by an ImageWallpaerService, and dynamic wallpaper is an open application that can be customized by each developer.

[0039] In a feasible implementation, an OSImageWallpaerService can be defined to implement the interface provided by Android for the wallpaper service requirements, and a wallpaper change and external display change monitor is added to the OSImageWallpaerService. When the external display or wallpaper changes, the Android system will notify the OSImageWallpaerService service. After receiving the notification, the OSImageWallpaerService service executes the following S402 step.

[0040] S402: Acquire target screen resources of the external display screen according to the wallpaper type.

[0041] It should be noted that the target screen resource varies according to the wallpaper type. The computer device can obtain different screen resources for different wallpaper types and perform corresponding cropping processing.

[0042] In one embodiment, when the wallpaper type is the static wallpaper type, the target screen resources of the external display screen include at least the screen number, screen direction and screen size of the external display screen; when the wallpaper type is the dynamic wallpaper type, the target screen resources of the external display screen include at least the screen identification, screen mode, screen number, screen direction and screen size of the external display screen.

[0043] This article stipulates that the screen direction may refer to the position of the external display screen relative to the main screen. For example, if the external display screen is located on the right side of the main screen, the screen direction may be right. Since the screen direction may affect the layout of the wallpaper after cropping, the computer device may obtain the screen direction in advance to perform corresponding processing according to the screen direction in the wallpaper cropping part. The screen mode refers to whether the external display screen is in extended screen mode or duplicate screen mode.

[0044] As a feasible implementation method, when the wallpaper type is a static wallpaper type, the screen mode is an extended screen mode and a copy screen mode, both of which can realize cropping and split-screen display of the wallpaper; when the wallpaper type is a dynamic wallpaper type, the screen mode is an extended screen mode, which can realize cropping and split-screen display of the wallpaper.

[0045] S403: Crop the wallpaper according to the target screen resources.

[0046] In one embodiment, the step of cutting the wallpaper according to the target screen resource includes:

[0047] The wallpaper is adaptively adjusted according to the number of screens and screen sizes in the target screen resources, wherein the adaptive adjustment includes any one or more of stretching, enlarging, and reducing the wallpaper; and the wallpaper after the adaptive adjustment is cropped.

[0048] As a feasible implementation, the computer device may provide options for the user, such as providing buttons for stretching, enlarging, reducing, etc. of the wallpaper, and the computer device may perform adaptive adjustments according to the specific effect selected by the user. Alternatively, the computer device may also automatically adjust according to the resolution of the main screen and the external display, the size of the external display, etc., to ensure that the wallpaper can cover every area of ​​each display after being cropped.

[0049] It should be noted that the above adaptive adjustment process is applicable when the wallpaper is a dynamic wallpaper or a static wallpaper.

[0050] In one embodiment, before the wallpaper is cropped according to the target screen resources, it also includes: when the wallpaper type is the dynamic wallpaper type, judging whether the external display supports wallpaper cropping display according to the screen size and screen mode of the external display; if so, cropping the wallpaper according to the target screen resources.

[0051] It should be noted that since dynamic wallpapers are displayed in the form of animation, when they are cropped, the original animation effects of the dynamic wallpapers may be destroyed. Therefore, the dynamic wallpaper can be set to crop and display the wallpaper only on external display screens that meet the preset display conditions, which can guarantee the display effect of the dynamic wallpaper to a certain extent.

[0052] For example, the preset display condition can be met when the screen mode of the external display is the extended screen mode and the screen size of the external display meets the cropping size requirement of the dynamic wallpaper. When the computer device determines that the external display meets the preset display condition, the wallpaper can be cropped according to the acquired target screen resources.

[0053] For another example, the way to crop the wallpaper can be: suppose the computer device is connected to an external display screen, which is located to the right of the main screen. The resolution of the main screen and the external display screen are both 3840*2160, and the length and width of the wallpaper are also 3840*2160. The computer device can first obtain the wallpaper resource through WallpaperManager.getBitmap provided by the Android system, and then divide the wallpaper bitmap into two parts (0, 0, 1920, 2160) and (1920, 0, 3840, 2160), and then crop two pictures.

[0054] S404: Distribute the cropped wallpaper to the main screen and the external display screen for display.

[0055] As a feasible implementation, when the wallpaper type is a static wallpaper type, the computer device can apply the cropped wallpaper to the screen that needs to display the cropped wallpaper content, and set it as the new wallpaper of the screen to display the wallpaper.

[0056] As another feasible implementation, when the wallpaper type is a dynamic wallpaper type, the computer device can use the LiveWallpaper service of the Android system to divide the screen into multiple areas according to the screen size and number of external display screens, and provide an independent Canvas object for each area to draw content (the Canvas object can correspond to the acquired screen identifier) ​​to display different content on each screen area, adapt to different screen sizes and aspect ratios, and realize the distribution of the cropped wallpaper to the main screen and the external display for display.

[0057] It can be seen that through the wallpaper display method provided in the embodiment of the present application, the computer device obtains the wallpaper resource of its own main screen, and determines the wallpaper type according to the wallpaper resource, obtains the target screen resource of the external display screen according to the wallpaper type, and crops the wallpaper based on the target screen resource, and distributes the cropped wallpaper to the main screen and the external display screen for display, which can realize partial display of the same wallpaper on multiple screens, forming visual coherence and improving the user's viewing experience.

[0058] The method of the present application is introduced above, and the device of the present application is introduced below.

[0062] The processing module 503 is used to crop the wallpaper according to the target screen resources.

[0063] The display module 504 is used to distribute the cropped wallpaper to the main screen and the external display screen for display.

[0064] In a possible design, the wallpaper type includes a dynamic wallpaper type and a static wallpaper type. When the wallpaper type is the static wallpaper type, the target screen resources of the external display screen include at least the number of screens, screen direction, and screen size of the external display screen; when the wallpaper type is the dynamic wallpaper type, the target screen resources of the external display screen include at least the screen identifier, screen mode, number of screens, screen direction, and screen size of the external display screen.

[0065] In a possible design, the processing module 503 is used to crop the wallpaper according to the target screen resources, specifically to: adaptively adjust the wallpaper according to the number of screens and screen sizes in the target screen resources, the adaptive adjustment including any one or more of stretching, enlarging, and reducing the wallpaper; and crop the adaptively adjusted wallpaper.

[0066] In a possible design, the device also includes: a judgment module, which is used to judge whether the external display screen supports wallpaper cropping display according to the screen size and screen mode of the external display screen when the wallpaper type is the dynamic wallpaper type; if so, the processing module 503 crops the wallpaper according to the target screen resources.

[0067] In one possible design, the device also includes: a monitoring module, used to monitor whether the wallpaper of the main screen of the computer device and / or the external display screen changes; if so, the determination module 501 obtains the wallpaper resource of the main screen of the computer device, and determines the wallpaper type based on the wallpaper resource.
