This application relates to an active pen and an active pen configuration method, belonging to the field of electronic device technology. The active pen includes: a pen body; at least two pen tail modules detachably connected to the pen body; and a controller configured in the pen body. The controller is used to: determine the pen tail type of the target pen tail module when a successful connection between the target pen tail module and the pen body is detected; wherein the target pen tail module is any one of the at least two pen tail modules; obtain configuration parameters of the target pen tail module according to the pen tail type; and send the configuration parameters to the target pen tail module. The active pen in this application includes multiple pen tail modules. Since each pen tail module is detachably connected to the pen body, users can flexibly replace different pen tail modules according to their own needs. This satisfies users' flexible selection of various functions of the active pen, reduces the user's cost of using various functions of the active pen, and also reduces the manufacturer's development cost.

This invention proposes a touch display device for use with an active pen. During touch sensing, the touch position is detected. During active pen sensing, an uplink signal is transmitted and a downlink signal is detected. When a downlink signal is detected, it is determined whether the distance between the active pen position and the touch position is less than or equal to a first preset distance; if so, the device does not enter active pen mode.
