Abstract
A touch device is disposed on a substrate having a plurality of scan lines. The touch device comprises a plurality of readout lines and a plurality of sensors. The readout lines and the scan lines are intersected with each other, and the sensors are electrically coupled to the corresponding scan lines and the corresponding readout lines respectively. A scan signal is introduced into the scan lines in sequence to control whether turning on the sensors, and the scan signal comprises at least one first turn-on pulse and a second turn-on pulse to simultaneously turn on at least two sensors which are electrically coupled to different scan lines.
