摘要
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.
