Claims (3)
- (2회 정정) 고압용B+발생회로(10), 고압발생회로부(20), 밝기조절부(30) 스포트킬러부(40) 및 CRT(50)등을 포함하는 통상의 스포트킬러회로에 있어서, 전원 오프 또는 전원관리(DPMS) 동작중 서스팬드모드에서 오프모드로의 전환시에 상기 스포트킬러부(40)를 통해 제1그리드(G1) 전압이 방전되는 시간보다 상기 고압발생회로부(20)의 동작정지시간이 빠르도록 상기 고압발생회로부(20)로 입력되는 수평드라이브펄스(Drive pulse)를 차단하는 드라이브펄스 억제회로(100)를 더 구비하여 된 것을 특징으로 하는 스포트킬러회로.
- (2회 정정) 제1항에 있어서, 상기 드라이브펄스 억제회로(100)는 상기 고압발생회로부(20)의 고압 발생용 트랜지스터(Q2)의 베이스 구동 펄스를 생성시키도록 수평드라이브펄스(Drive pulse)에 의해 스위칭되는 펄스 스위칭 트랜지스터(Q1)의 베이스단과, 수평드라이브펄스(Drive pulse)가 입력되는 입력단 사이에 개재하여 된 것을 특징으로 하는 스포트 킬러 회로.
- (2회 정정) 제1항에 있어서, 상기 드라이브펄스 억제회로(100)는 수평드라이브펄스(Drive pulse)를 검출하는 저항(R19)과, 분압용 저항(R17)(R18)과, 짧은 방전 시간을 갖는 충·방전용 캐패시터(C8, C9)와, 전원 오프 시 또는 전원 관리(DPMS) 동작 중의 오프 모드시에 상기 고압발생회로부(20)에 수평드라이브펄스(Drive pulse)가 유입되지 않도록 차단하는 펄스 차단용 트랜지스터(Q8)를 포함하여 된 것을 특징으로 하는 스포트 킬러 회로.
