AI Technical Summary
In existing technologies, the screen projection methods for foldable full-screen terminal devices cannot adapt to the desktop and window partitioning after the screen is folded, resulting in poor projection display effects.
Each display screen is configured with a corresponding display. By responding to the screen casting command, the display of the first and second displays screens is created, and a screen casting prompt is displayed on the terminal device. The target projection device and display screen are determined, and the interface is projected to the target device based on the display of the target display screen, thus realizing personalized screen casting.
It enables projection to be directed to either the first or second display screen based on user needs, enhancing the personalized experience and display effect of screen projection while reducing the load on terminal devices.

Abstract
Claims
1. A screen projection method, characterized in that, Applied to a terminal device, the terminal device including: a first display screen and a second display screen, the method including: In response to the screen mirroring command, a first display function corresponding to the first display screen is created, and a second display function corresponding to the second display screen is created; A screen mirroring prompt is displayed on the terminal device; Based on the screen projection prompts, the target projection device and target display screen are determined; The interface of the target display screen is projected onto the target projection device based on the display corresponding to the target display screen.
2. The method according to claim 1, characterized in that, Creating the first display corresponding to the first display screen includes: Determine the first screen width of the first display screen; The height coordinate parameters in the initial display of the terminal device are adjusted according to the first screen height to obtain the first display.
3. The method according to claim 1, characterized in that, Creating the second display corresponding to the second display screen includes: Determine the second screen height and the second screen width of the second display screen; A first coordinate parameter is generated based on the height of the second screen, and a second coordinate parameter is generated based on the width of the second screen; The second display is determined based on the first coordinate parameter and the second coordinate parameter.
4. The method according to claim 1, characterized in that, The method further includes: Obtain the overall load of the terminal device; Based on the overall load, it is determined that the frame rate of the non-target display needs to be adjusted, and the frame rate percentage of the non-target display is determined; wherein, if the target display is the first display, then the non-target display is the second display, and if the target display is the second display, then the non-target display is the first display. The target frame rate is determined based on the frame rate percentage. Adjust the frame rate of the non-target display to the target frame rate.
5. The method according to claim 4, characterized in that, Determining the frame rate percentage of the non-target display screen includes: Determine the focal distance between the first focal point of the target display screen and the second focal point of the non-target display screen; The physical distance between the first focal point and the second focal point is obtained based on the focal distance and pixel density; The frame rate calculation function is determined based on the physical distance and the preset distance threshold. The frame rate percentage is obtained based on the frame rate calculation function and the physical distance.
6. The method according to claim 1, characterized in that, After the display corresponding to the target display screen is projected onto the target projection device, the method further includes: Based on the first frame data, it is determined that there is a refresh area in the target display screen, and the display data corresponding to the refresh area is sent to the target projection device; the first frame data is the next frame data of the current frame data being displayed in the target display screen.
7. The method according to claim 1, characterized in that, Before creating the first display corresponding to the first display screen and creating the second display corresponding to the second display screen, the method further includes: Determine the folding angle between the first display screen and the second display screen; The terminal device is determined to be in a folded state based on the folding angle.
8. A screen projection device, characterized in that, Applied to a terminal device, the terminal device including: a first display screen and a second display screen, the device including: The response module is used to respond to the screen projection command, create a first display corresponding to the first display screen, and create a second display corresponding to the second display screen; The prompt module is used to display a screen projection prompt on the terminal device; The determination module is used to determine the target projection device and the target display screen based on the projection prompt; The screen projection module is used to project the interface of the target display screen to the target projection device based on the display value corresponding to the target display screen.
9. An electronic device, characterized in that, It includes a memory for storing computer program instructions and a processor for executing the program instructions, wherein when the computer program instructions are executed by the processor, the electronic device is triggered to perform the method of any one of claims 1-7.
10. A computer-readable storage medium, characterized in that, The computer-readable storage medium includes a stored program, wherein, when the program is executed, it controls the device on which the computer-readable storage medium is located to perform the method according to any one of claims 1-7.
11. A computer program product, characterized in that, The computer program product includes: computer program code, which, when run on a computer, causes the computer to perform the method described in any one of claims 1-7.
