Abstract

본 발명은 드라이빙 커패시터를 통해 인가되는 드라이빙전압에 의해 터치패드에서의 드라이빙 백(Driving Back) 현상을 검출하여 터치신호를 검출하는 새로운 방식의 터치 검출수단, 검출방법 및 터치스크린패널과, 그러한 터치스크린패널을 내장한 표시장치에 관한 것이다. 본 발명의 터치 검출수단은, 표시장치의 상면에 부가되며 신체의 손가락(25) 또는 이와 유사한 도전체와 같은 터치입력수단의 접근에 의해 터치커패시턴스(Ct)가 발생하는 것을 감지하는 터치 검출수단에 있어서, 상기 터치입력수단과의 사이에서 터치커패시턴스(Ct)를 형성하는 터치패드(10); 상기 터치패드(10)에 일측이 연결되고 타측으로는 터치 검출을 위한 드라이빙(Driving) 전압이 인가되는 드라이빙 커패시터(Cdrv); 상기 표시장치에서 발생하는 공통전압을 검출하는 검출부; 상기 공통전압에 동기하여 드라이빙 전압을 생성하는 드라이빙전압 생성부; 및 상기 터치패드(10)에 연결되며, 상기 터치입력수단의 터치 유무에 따라 상기 드라이빙 커패시터(Cdrv)에 상기 터치커패시턴스(Ct)가 부가될 때 드라이빙 백(Driving Back) 현상을 이용하여 터치신호를 검출하는 터치검출부(14);를 포함하여 구성된 것을 특징으로 한다.
