APPARATUS FOR DETERMINING TOUCH POSITION AND METHOD FOR THE SAME

摘要

PURPOSE: A touch area checking apparatus and a method thereof are provided to freely set up a position of a touch screen panel regardless of a position of a display panel and easily adjust a quantity of noise reducing by adjusting a length of a band spreading code. CONSTITUTION: A TSP(Touch Screen Panel)(310) is equipped with a first electrode layer of a first pattern aligned to a first direction and a second electrode layer of a second pattern aligned to a second direction. A signal generating unit(320) generates a band spreading signal and supplies the band spreading signal to the first electrode layer. A signal restoration unit(330) processes band restoration to the signal inputted from the second electrode layer. A touch area coordinate confirmation unit(340) confirms coordinates of a touch area from the signal outputted from the signal restoration unit.
