Abstract

본 발명은 터치스크린 컨트롤 장치에 관한 것으로, 화소 양단에 인가되는 전압을 반전시켜 구동하는 구동부를 포함하는 LCD 디스플레이 장치와 상기 디스플레이 장치 전면에 설치되어 터치 좌표를 인식하여 그에 따른 터치출력값을 출력하는 정전용량측정부를 포함하는 터치스크린을 포함하는 디스플레이 장치의 터치스크린 제어장치에 있어서, 상기 터치스크린의 감지 전극과 전기적으로 연결되며, 상기 LCD 디스플레이 장치의 반전 신호를 받아 반전 노이즈로 인해 입력전압의 변화로 반전 신호의 전압과 이에 따른 비교기의 동작으로 출력되는 제 1출력전압 또는 제 2출력전압을 터치출력값으로 출력하도록 제어하는 노이즈처리부와, 상기 노이즈처리부에서 출력된 터치출력값을 상기 정전용량측정부에 반영하고, 이를 통해 상기 터치스크린으로부터 입력받은 사용자의 터치 조작에 따라 상기 디스플레이를 제어하는 제어부를 포함하여 구성되는 것을 특징으로 한다.
