Abstract
Embodiments of this application provide a refresh rate switching method, an electronic device, and a system. After being in a communication connection to a stylus, the electronic device may display a picture at a first refresh rate. The user may operate the electronic device, so that a refresh rate of the electronic device is switched from the first refresh rate to a second refresh rate. When the user holds the stylus again to approach a screen, the electronic device switches from the second refresh rate to a third refresh rate, where the first frequency is an integer multiple of the third refresh rate; and then after the electronic device sends a wake-up signal to the stylus, the stylus may intercept the wake-up signal, to send an uplink signal, and then the electronic device may receive the uplink signal from the stylus, and may keep signal synchronization with the stylus.
