Abstract: Embodiments of this application provide a frame rate switching method and a related apparatus, and relate to the field of terminal technologies. In a frame rate switching process, a plurality of transition frame rates can be set. A difference value between any two adjacent transition frame rates of the plurality of transition frame rates is less than a preset value, to enable switching of a screen refresh rate of a display screen to be smoother without spanning too much; and in a switching process, a drawing frequency on an application processor AP side of a terminal device is kept synchronously changing with a TE signal obtained from an IC by the AP side, to avoid frame loss during switching.
