Abstract

2 이상의 접촉 입력들을 감지하기 위한 방법에 있어서, 복수의 감지 전극에 의해 감지 신호를 수신하는 단계와, 상기 수신된 감지 신호로부터 상기 접촉 입력들간의 거리에 의존하는 값을 획득하는 단계와, 상기 획득된 값이 문턱값 이상인 경우에 2 이상의 상기 접촉 입력들이 존재하는 것으로 결정하는 단계를 포함하는 접촉 입력 감지 방법이 제공된다. 복수의 감지 전극은 동일한 제 1 축 좌표에 대응되는 감지 전극쌍을 포함하고, 상기 감지 신호를 수신하는 단계는 상기 제 1 축을 따라 상기 감지 전극쌍으로부터 감지 신호를 수신한다.
