Abstract
The present application provides a synchronization method and a synchronization device, which may effectively realize synchronization between a touch screen and the active pen. The synchronization method is configured for time synchronization between a first detection chip of a first device and a second detection chip of a second device, and the method includes: a first wireless communication chip connected to the first detection chip, receiving the first synchronization signal sent by the first detection chip at a first moment; the first wireless communication chip sending time information associated with the first moment to a second wireless communication chip connected to the second detection chip; and the time information being configured to determine a second moment for the first detection chip to send the synchronization signal next time, so that the second detection chip is synchronized with the first detection chip at the second moment.
