  • Patent number: 12254828
    Abstract: A method for controlling dynamic change of a screen refresh rate and an electronic device are provided. In a scenario of dynamic change of the refresh rate, a refresh rate switching instruction may be sent immediately through an added refresh rate setting interface (displaySetFps) within a current ith frame period before a current Vsync periodicity ends. After receiving the refresh rate switching instruction, a DDIC drives a display screen to switch a screen refresh rate, and then the DDIC returns a new TE signal. After receiving the new TE signal, SurfaceFlinger starts a new Vsync periodicity corresponding to a switched screen refresh rate. In an embodiment of this application, a switching speed at which the screen refresh rate is switched may be increased by adding a new path. For example, it may be ensured that each switching of the screen refresh rate is completed within one frame.
