TOUCH DETECTING DEVICE REDUCING NOISE INFLUENCE AND TOUCH DETECTING METHOD

摘要

The present invention relates to a touch detecting device reducing a noise influence. It outputs a level shift value based on a difference of a voltage change occurring by operating a touch sensing unit corresponding to a sensor pad, sequentially calculates touch coordinates and touch area by using the level shift value, and efficiently removes a noise to the sensor pad.;COPYRIGHT KIPO 2014;[Reference numerals] (210) Touch detecting part;(220) Touch information processing part;(230) Memory;(240) Control part
