Embodiments of the present application provide a display switching method, device, electronic equipment, and storage medium, wherein the method includes: obtaining a display switching instruction, the display switching instruction includes a target display signal of a target hardware display processing unit, and obtaining the current hardware display signal according to the display switching instruction. Display the state of the first frame synchronization signal of the processing unit and the state of the second frame synchronization signal of the target hardware display processing unit, and display the current output of the switching module according to the state of the first frame synchronization signal and the state of the second frame synchronization signal The first display signal from the current hardware display processing unit is switched to the target display signal, wherein the state of the first frame synchronization signal and the state of the second frame synchronization signal are acquired at different times. In this embodiment of the present application, switching of display content of applications of different operating systems / different domains / different CPU cores is triggered only by the state of the frame synchronization signal, thereby achieving low complexity and improving display switching efficiency.
Description
technical field [0001] The present application relates to the field of display technology, and in particular to a display switching method, device, electronic equipment and storage medium. Background technique [0002] In a system installed with a system-on-a-chip, different applications are usually implemented by multiple operating systems, such as applications based on the Linux operating system or real-time operating system (Real Time Operating System, RTOS) applications or applications based on the Android system. Different operating systems are isolated. Alternatively, multiple different domains / CPU cores are involved in the operating system, different domains / CPU cores are used to implement different applications, and different domains / CPU cores are isolated. When the display content of applications from different operating systems or different domains or different CPU cores needs to be displayed on the same display screen, video switching will be involved.
