Abstract

The present application provides a method, device and electronic device for controlling the display frequency of a display screen. The method includes, in a command mode, determining whether the display screen is in self-refresh state if the application processor is not currently transmitting image data to the display screen. If the display screen is in the self-refresh state, wait for the display screen to self-refresh and send notification information to the application processor. The notification information is used to notify the application processor to transmit image data to the display screen; receive the image transmitted by the application processor. data, and the display frequency is updated at the first frequency at which the application processor transmits the image data. The present application can effectively avoid the delay of frequency switching of the application processor AP, so that the display frequency of the display screen can be updated in time, and the display control effect can be improved.

Description

technical field [0001] The present application relates to the technical field of electronic equipment, in particular to a method, device and electronic equipment for controlling the display frequency of a display screen. Background technique [0002] With the development of electronic equipment, the signal transmission logic between the display screen and the application processor AP usually transmits image data to the display screen by the application processor AP at a certain frequency, so that the display screen can display the image data, and then In some application scenarios, the display screen and the application processor AP will also transmit corresponding command signals to each other. For example, the application processor AP can control the display screen by transmitting command signals to the display screen, and the display screen can also send the The AP transmits a corresponding instruction signal, thereby notifying the application processor of the current sta...
