1. A refresh rate switching method, applied to an electronic device, wherein the method comprises:
running, by the electronic device, a first application;
displaying, by a display screen integrated circuit IC of the electronic device, image data corresponding to the first application on the display screen based on a first refresh rate, and transmitting, by a system on chip (SOC) of the electronic device, the image data corresponding to the first application to the display screen IC based on first transmission duration corresponding to the first refresh rate;
when the electronic device determines that a refresh rate of the display screen is to be switched, determining, by the electronic device, a second refresh rate;
when the second refresh rate is lower than the first refresh rate, sending, by the SOC of the electronic device, a first switching instruction to the display screen IC;
switching, by the display screen IC, the refresh rate of the display screen from the first refresh rate to the second refresh rate based on the first switching instruction;
when the SOC of the electronic device determines that the switching of the refresh rate of the display screen is completed, switching, by the SOC of the electronic device, transmission duration of the image data corresponding to the first application from the first transmission duration to second transmission duration corresponding to the second refresh rate; and
transmitting, by the SOC of the electronic device, the image data corresponding to the first application to the display screen IC based on the second transmission duration, and displaying, by the display screen IC, the image data corresponding to the first application on the display screen based on the second refresh rate.
