    Abstract: An active stylus includes a stylus body and a touch sensor. The stylus body includes a first electrode and a pen body. The first electrode is used to send a signal. The pen body extends along a first direction. The touch sensor is provided on or in the pen body and includes a plurality of column electrodes extending along the first direction. There is a first gap between two adjacent column electrodes. Each column electrode has a first sensing electrode and a second sensing electrode. A first end of the first sensing electrode in the first direction has a recess to define a recess area. A second end of the second sensing electrode in the first direction has a projection extending into the recess area. There is a second gap between the projection and the recess. The second gap is smaller than the first gap.
