Problems solved by technology
[0003] The traditional solution is to switch the display interface of the display screen, but this solution is not suitable for the current system installed with the system-on-chip. In the system installed with the system-on-chip, when it is necessary to realize different If the switching between the display content of the application is not handled, a black screen will appear during the switching process, and the seamless switching between the display content of different applications cannot be realized.

The embodiment of the present application relates to the field of display control technology, and provides a display switching method and device. The method includes: receiving and processing the first display content of the first running application through the first processing unit, and obtaining the first display content of the first display content. The image frame and the first frame end signal of the first image frame; the second processing unit receives and processes the second display content of the second running application to obtain the second image frame of the second display content and the second image frame of the second image frame. End of frame signal; when it is determined that the display unit is to be switched from displaying the first display content to displaying the second display content, close the data connection between the first processing unit and the display unit according to the first frame end signal; open the second processing unit and the display unit The data connection is used to display the second image frame of the second display content through the display unit. The embodiment of the present application can realize seamless switching between display contents of different applications.
Description
technical field [0001] The embodiments of the present application relate to the technical field of display control, and in particular, to a display switching method and device. Background technique [0002] In a system installed with a system-on-a-chip, multiple operating systems are usually used to implement different applications. Applications can be divided according to domains, such as Linux-based or real-time operating system (Real Time Operating System, RTOS) or Android-based Domains, different domains are based on different operating systems, and different operating systems are completely isolated without virtualization. When the display content of applications from different operating systems needs to be displayed on the same display screen, switching between different hardware display processing units (Display Processor Uint, DPU) will be involved. [0003] The traditional solution is to switch the display interface of the display screen, but this solution is not s...
