Abstract

본 고안은 파우어 온시나 주파수 변환시 또는 파우어 운용 시스템에서의 수평 동기 신호나 수직 동기 신호가 없을 경우 화면에 나타나는 노이즈를 제거할 수 있는 모니터의 비디오 뮤트 회로에 관한 것으로 마이컴(10)의 뮤트 단자(P1)에 접속되어 파우어 온시나 주파수 변환시 스위칭되는 제1스위칭수단(20)과, 상기 마이컴(10)의 파우어 운영 단자(P2)에 접속되고 파우어 운영 시스템에서의 수평, 수직 동기가 없을때 스위칭되어 상기 제1스위칭수단(20)의 출력을 제어하는 제2스위칭수단(30)을 포함하여 이루어지며 상기 제1, 2스위칭수단(20)(30)으로 트랜지스터(Q1)(Q2)를 사용하여 이루어진 것이다.The present invention relates to a video mute circuit of a monitor that can remove noise on a screen when there is no horizontal sync signal or vertical sync signal in power on, frequency conversion, or power operation system. 1 ) is connected to the first switching means (20) to be switched on during power-on or frequency conversion, and the power operating terminal (P 2 ) of the microcomputer 10 and switching when there is no horizontal and vertical synchronization in the power operating system And second switching means 30 for controlling the output of the first switching means 20 and using transistors Q1 and Q2 as the first and second switching means 20 and 30. It is done.
