Abstract

본 발명은 적외선 스캔 방식의 터치스크린 장치에 관한 것으로, 보다 상세하게는 송신 측에 적외선 레이저 스캐너를 구비하고 수신 측에 도광바(Light Guide Bar) 및 적외선 수신 포토트랜지스터를 구비하며, X/Y 좌표를 검출하기 위한 디코더를 구비한 터치스크린 장치에 대한 것이다. 본 발명에 따른 적외선 스캔 방식의 터치스크린 장치는 사용자가 터치하고 이미지를 스크린상에서 또는 스크린을 통하여 뷰잉할 수 있는 스크린과; 상기 스크린의 2 개 이상의 에지에 설치되어, 상기 스크린의 전 영역을 일정한 주기로 적외선 스캔하는 2개 이상의 적외선 레이저 스캐너와; 상기 스크린의 테두리부에 설치되는 도광바와; 상기 도광바의 말단에 설치되는 적외선 수신 포토트랜지스터 및; X/Y 좌표를 검출하기 위한 X/Y 디코더로 구성되며; 상기 X/Y 디코더는 상기 적외선 수신 포토트랜지스터에서 읽어 들인 광량에 대한 정보와 상기 적외선 레이저 스캐너에서 읽어 들인 레이저 빔의 각도 정보를 이용하여 스크린 상에 접촉된 물체의 X/Y 위치 정보와 크기 정보를 계산하는 것을 특징으로 한다. 본 발명에 따른 적외선 스캔 방식의 터치스크린 장치는 기존의 적외선 LED 및 적외선 수신 포토트랜지스터를 매트릭스 형태로 배치한 방법에 비하여 구조가 지극히 간단하며 스크린의 크기가 커지더라도 비용의 증가 없이 유연하게 대응할 수 있고, 동시에 여러 터치 점을 검출할 수 있는 멀티 터치 기능을 구현할 수 있다.
