Abstract

감지 전극을 포함하는 접촉 입력 감지 장치에서 접촉 입력을 감지하는 방법이 개시된다. 접촉 입력 감지 방법은 제1시간 동안 상기 감지 전극의 입력단에서 구동 신호를 공급하고 감지 신호를 산출하는 제1단계와, 제2시간 동안 상기 감지 전극의 상기 입력단에서 구동 신호를 공급하고 감지 신호를 산출하는 제2단계와, 상기 제1단계에서 산출된 감지 신호와 상기 제2단계에서 산출된 감지 신호의 차이에 기초하여 접촉 입력의 위치를 결정하는 제3단계를 포함하되, 상기 제1시간과 상기 제2시간은 서로 다른, 접촉 입력 감지 방법이 제공된다. 이로써, 2 이상의 접촉 입력이 인가된 경우에도 접촉 입력의 좌표를 정확하게 결정할 수 있다.
