Abstract

본 발명에 따른 터치 스크린의 리드아웃 회로부는, 복수의 터치 센서가 터치 스크린 패널(TSP) 내부 또는 외부에 행과 열의 매트릭스 형태로 배열된 터치 센서부; 상기 터치 센서 각각의 전기적 변화를 감지한 후 이를 전압값으로 변환하여 저장하는 센싱 블록; 일정 간격을 두고 선택된 2개의 상기 센싱 블록에 각각 저장된 2개의 센싱 전압값의 차이를 인가 받아 델타(△) 전압을 만들어 내는 델타 회로부; 상기 델타회로부에서 출력된 아날로그 신호를 N(자연수) 비트의 디지털 신호로 변환하는 아날로그-디지털 변환기(ADC)를 제공함에 기술적 특징이 있다.
