Claims (1)

스크린 터치 유무를 적외선 발광다이오드와 수광다이오드로서 감지하는 스크린 터치 방법에 있어서, 스크린이 터치되는 대향면에 적외선 발광 다이오드와 수광 다이오드를 교호로 연설시키어 적외선 발광다이오드의 확산을 방지하며 스크린터치시에 수광다이오드의 인가전압과 스크린의 각 모서리에 장설시킨 적외선 잡음 감지 수광 가이오드들에서 인가되는 적외선 잡음전압을 비교하도록한 스크린 터치키의 오동작 방지방법.A screen touch method for detecting the presence or absence of a screen touch as an infrared light emitting diode and a light emitting diode, wherein an infrared light emitting diode and a light receiving diode are alternately addressed to the opposite surface where the screen is touched to prevent diffusion of the infrared light emitting diode and is received by the screen touch. A method of preventing malfunction of a screen touch key by comparing an applied voltage of a diode with an infrared noise voltage applied from infrared light-sensing light receiving diodes installed at each corner of the screen. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
