Abstract: Embodiments of this application provide a method applied to a signal synchronization system, a system, a stylus, and an electronic device. The system includes a stylus and an electronic device. The electronic device supports a first refresh rate and a second refresh rate. The method includes: after an electronic device is wirelessly connected to a stylus, the electronic device samples a downlink signal from the stylus based on a third refresh rate, where the third refresh rate is equal to a first refresh rate or a second refresh rate; and the stylus sends the downlink signal to the electronic device based on the third refresh rate, and samples an uplink signal from the electronic device at a fourth refresh rate, where the fourth refresh rate is the least common multiple of the first refresh rate and the second refresh rate. In the embodiments of this application, after the stylus is connected to the electronic device, the uplink signal from the electronic device may be monitored by using the least common multiple of all refresh rates supported by the electronic device, so that the switching of the refresh rate of the electronic device can be detected in a timely manner, thereby achieving a small time delay and high efficiency.

Abstract: A pixel drive circuit and a drive method thereof, a display panel, and a terminal device, which are applied to the field of terminal technologies. The pixel drive circuit includes a first reset module, a light-emitting control module, and a drive module, and both the first reset module and the light-emitting control module are connected to a light-emitting control signal terminal, where one of the first reset module and the light-emitting control module is turned on when the light-emitting control signal is at a high level, and the other of the first reset module and the light-emitting control module is turned on when the light-emitting control signal is at a low level. Therefore, by increasing the frequency of the light-emitting control signal to greater than 120 Hz, a problem of a phenomenon of frequent flickering on an image during low-brightness display may be improved.

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.
