Abstract
A touch panel controller includes a signal driver charging a plurality of sensor lines extending in a direction with the same charge, by applying a driving signal to one sensor line of sensor lines and applying a mirrored driving signal mirrored from the driving signal to the remaining sensor lines of the sensor lines, and a sensor sensing a change in capacitance from the sensor lines, respectively.
