Abstract

본 발명은 적외선 광방식에 의한 터치스크린 모니터링 방법에 관한 것으로, 출력할 터치키가 있는 경우에만 적외선 LED를 스캔하도록 하여 적외선 LED의 무조건 스캔에 따른 통전열화를 최소로 줄이기 위한 것이다.The present invention relates to a touch screen monitoring method using an infrared light method, and to reduce the current degradation due to unconditional scanning of the infrared LED by scanning the infrared LED only when there is a touch key to output.

Description

터치스크린 모니터링방법How to monitor touch screen

본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음Since this is an open matter, no full text was included.

제3도는 본 발명이 적용되는 터치스크린 모니터링 장치의 구성도.3 is a block diagram of a touch screen monitoring apparatus to which the present invention is applied.

제4a,b도는 제3도의 키번호 버퍼의 동작 상태를 나타낸 모니터링 장치로 출력된 터치키의 구성도.4A and 4B are diagrams illustrating the configuration of a touch key output to a monitoring device showing an operating state of the key number buffer of FIG.

제5도는 본 발명에 의한 터치스크린 모니터링 방법의 흐름도.5 is a flowchart of a touch screen monitoring method according to the present invention.

Claims (1)

출력할 터치키의 갯수가 저장된 키번호 버퍼의 값이 "0"인지 검색하는 단계(10), "0"이면 적외선 LED를 스캔하지 않고 종료하는 단계(11), "0"이 아니면 터치셀 영역이 있을때까지 적외선 LED를 스캔하는 단계(12,13), 상기 키번호 버퍼의 값이 될때까지 포인터를 증가시키면서 상기 터치셀 영역이 있는 좌표 테이블의 좌표를 찾는 단계(14,17,18), 상기 터치셀 영역이 있는 좌표테이블의 좌표를 찾으면 해당하는 명령을 수행하는 단계(15,16), 및 상기 포인터 키번호 버퍼의 값이 될때까지 터치셀 영역이 있는 좌표 테이블의 좌표를 찾지 못하면 현 상태를 출력하는 단계(19)를 포함하여 이루어지는 것을 특징으로 하는 터치스크린 모니터링방법.Searching whether the value of the stored key number buffer is "0" (10); if "0", ending without scanning the infrared LED (11); otherwise, the touch cell area Scanning (12,13) the infrared LED until it is present, finding (14, 17, 18) the coordinates of the coordinate table where the touch cell area is located while increasing the pointer until the value of the key number buffer is reached. If the coordinates of the coordinate table with the touch cell area are found, performing the corresponding command (15, 16), and if the coordinates of the coordinate table with the touch cell area are not found until the value of the pointer key number buffer is reached, the current state is displayed. Touch screen monitoring method comprising the step of outputting (19). ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
