Abstract

본 발명은 터치 스크린 모니터링 장치에 관한 것으로, 일반적인 적외선 광 방식에 의한 터치 스크린에서는 터치판넬의 한 곳 이상을 차단하게 되면 2이상의 터치 셀 좌표가 만들어지게 되며, 이러한 경우 씨피유에서는 터치 셀 좌표중 어느 것이 유효한 터치 셀인지를 잘못 판단하여 원하지 않는 명령을 수행하게 되는 경우가 있다.The present invention relates to a touch screen monitoring apparatus, and when a touch screen by a general infrared light method blocks at least one place of a touch panel, two or more touch cell coordinates are created. There is a case where an incorrect command is determined by incorrectly determining whether a valid touch cell is used.

이에 따라 본 발명은 상기와 같은 종래의 터치 스크린 시스템에 따르는 결함을 해결하기 위하여, 터치된 영역의 좌표를 터치 키 좌표 테이블의 값과 비교하여 일정 값 이상이 되거나 유효한 값이 2이상일 때에는 부적절한 입력으로 판단함으로써 오동작을 방지하게 하는 터치 스크린 모니터링 회로를 제공하는데 그 목적이 있다.Accordingly, in order to solve the deficiency according to the conventional touch screen system, the present invention compares the coordinates of the touched area with a value of the touch key coordinate table, and when the value is more than a predetermined value or the valid value is 2 or more, an inappropriate input is generated. It is an object of the present invention to provide a touch screen monitoring circuit which makes it possible to prevent malfunction by judging.
