Abstract

Embodiments of the present disclosure provide a method and a device for controlling a refresh rate of a mobile terminal and a mobile terminal. The method includes: determining that each of at least one foreground applications running currently is in a whitelist consisting of preset applications; obtaining a preset refresh rate corresponding to each of the at least one foreground application in the whitelist, and determining a target refresh rate of a display screen of the mobile terminal according to the preset refresh rate corresponding to each of the at least one foreground applications, in which an operation mode of the display screen is a command mode; and controlling the display screen by a display controller to read display frame data to be displayed from a frame buffer unit of the display screen at a frequency same as the target refresh rate and to display the display frame data.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of mobile terminals, and in particular, to a method and device for controlling the refresh rate of a mobile terminal, and a mobile terminal. Background technique [0002] With the development of mobile terminal technology, various mobile terminals have become indispensable tools in people's life and work. In a mobile terminal installed with an operating system, the mobile terminal continuously refreshes the display screen to present various display screens at different times. [0003] The display refresh process in a mobile terminal such as a mobile phone mainly includes a picture drawing operation, a picture composition operation and a display operation. Each application, such as desktop or video, executes the Render operation to draw its own image; after all the applications complete the Render operation, the system executes the Compose operation to combine the images drawn by ea...
