Abstract
A method, device and non-transitory computer-readable medium for control of a refresh frequency of a display unit are disclosed. The display unit is in communication with a processor and configured to display image frames processed by the processor on a screen of the display unit. The method includes: acquiring a real-time frame composition frequency corresponding to an amount of time required for the processor to complete composition of an image frame to be displayed; determining a refresh frequency of the display unit based on the real-time frame composition frequency, when the real-time-frame composition frequency satisfies a preset condition; and refreshing the screen of the display unit at the determined refresh frequency.
