Abstract
Description
Claims (1)
- 비데오/크로마 IC(40)의 휘도신호(-Y)가 트랜지스터(Q2)를 통한후 트랜지스터(Q1)에서 색차신호(R-Y)와 혼합되어 색신호(-R)를 CRT(10)의 캐소드에 인가시키는 CRT 드라이브 회로에 있어서, 트랜지스터(Q1)의 색신호를 CRT(10)의 캐소드에 인가시키는 저항(R2)과 CRT(10)의 캐소드 사이에 연결되고 CRT(10)의 방전 전류를 통과시키는 다이오드(D1)와, 상기 다이오드(D1)의 일측에 연되고 저항(R2)과 병렬 연결되는 저항(R3)과, 상기 저항(R3)의 양단 전압에 의하여 구동되고 IC 보호장치(2 0)와 마이콤 보호부(30) 및 비데오/크로마 IC(40)의 급격 방전에 의한 파괴 방지용 회로에 트리거 신호를 인가시키는 트랜지스터(Q3)로 구성된 CRT 방전에 의한 반도체 파괴 방지 회로.
