Abstract

The invention provides a method and device for controlling the display frequency of a display screen and electronic equipment, and the method comprises the steps: judging whether the display screen isin a self-refreshing state or not in a command mode if an application processor does not transmit image data to the display screen at present; if the display screen is in the self-refreshing state, sending notification information to the application processor after self-refreshing of the display screen is completed, wherein the notification information is used for notifying the application processor to transmit image data to the display screen; and receiving the image data transmitted by the application processor, and updating the display frequency at a first frequency at which the application processor transmits the image data. According to the application, the delay of the frequency switching of the application processor AP can be effectively avoided, so that the display frequency of the display screen can be updated in time, and the display control effect is 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...
