Abstract

본 발명은 접촉 감지 패널 및 접촉 감지 장치에 관한 것이다. 본 발명에 따른 접촉 감지 패널은, 기판, 및 상기 기판상에 마련되는 하나 이상의 감지 영역을 포함하고, 상기 감지 영역은 제1축 방향으로 연장되는 하나 이상의 제1전극과, 상기 제1축과 교차하는 제2축 방향으로 연장되는 하나 이상의 제2전극을 포함하며, 상기 제2전극 중 적어도 일부는, 서로 다른 감지 영역에 포함되고 제1축 상의 동일한 위치에 배치되는 다른 제2전극과 전기적으로 연결된다. 본 발명에 따르면, 구동 신호가 인가되는 제1전극의 내측으로 마련된 공간에 제2전극을 배치하거나, 전극의 형태를 따라 그 주변을 제1전극이 둘러싸도록 제2전극을 배치함으로써 단층 구조로 하나 이상의 접촉 입력을 정확히 판단할 수 있는 접촉 감지 패널 및 접촉 감지 장치를 제공할 수 있다.
