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.

Synchronization method, wireless communication chip, synchronization device, electronic device and active pen

A method and an apparatus for pressure detection, an active pen, a touch control chip and an electrode device are provided, configured to detect a pressure of the active pen on a screen. The active pen includes a pressure sensor, a wireless communication module and a tip electrode, and the pressure sensor is configured to detect the pressure generated by the active pen. The method includes: determining a second pressure level corresponding to the pressure, according to a detection signal corresponding to a first driving signal output by the tip electrode, when a pressure signal of a first pressure level corresponding to the pressure sent by the wireless communication module is not received; and displaying handwriting of the active pen, by the screen, according to the second pressure level. The method can reduce time delay of a response of a first writing of the active pen.

Method and apparatus for pressure detection, active pen, touch control chip, and electronic device

The present application provides a synchronization method. The method includes: transmitting, by a first wireless communication chip of the electronic device, a synchronization signal to a second wireless communication chip of the active pen and simultaneously transmitting a first indication signal to a touch control chip of the touch screen; where the first indication signal is used to instruct the touch control chip to detect a driving signal transmitted by the active pen after from reception of the first indication signal, the second wireless communication chip is further configured to transmit a second indication signal to a driving chip of the active pen while receiving the synchronization signal, the second indication signal is used to instruct the driving chip to transmit the driving signal after from reception of the second indication signal, the second preset duration is less than the first preset duration.

Synchronization method, wireless communication chip, touch control chip, and driving chip

The present disclosure relates to touch technology, and provides a method for preventing an edge from being unintentionally touched, a touch control apparatus and a storage medium. The method comprises: acquiring touch data of a touch screen in real time; judging whether there is any edge touch operation according to the touch data; calculating a coordinate point movement track of the edge touch operation according to the touch data if there is an edge touch operation; judging whether the edge touch operation is an edge mis-operation according to the touch data and the coordinate point movement track; and suppressing the edge mis-operation if the edge touch operation is an edge mis-operation. With embodiments of the present disclosure, accuracy of edge mis-operation recognition is improved while ensuring a normal response of an edge region of a screen.
