Abstract
A method for synchronization between an active stylus and a touch screen, and an active stylus are provided, which can improve the synchronization speed between the touch screen and the active stylus. The method includes: transmitting a pre-synchronization signal to the touch screen, wherein the pre-synchronization signal is used to determine a target region where the active stylus is located on the touch screen, so that the touch screen transmits an uplink signal in the target region; detecting the uplink signal; and performing, in response to the uplink signal being detected, time synchronization with the touch screen based on the uplink signal.
