Abstract
Description
Claims (1)
- 트랜지스터(TR1, TR2), 저항(R1-R4) 및 콘덴서(C1)로 구성되어 영상신호입력단자(YS)의 영상신호를 증폭하는 케이케이드증폭기(1)의 출력측인 상기 트랜지스터(TR1)의 콜렉터가 저항(R51)을 통해 브라운관(2)의 캐소드에 접속 되고 수평 펄스입력단자(HS)가 다이오드(D1), 저항(R8) 및 코일(L1)을 통해 상기 트랜지스터(TR1)의 콜렉터에 접속됨과 아울러 상기 다이오드(D1) 및 저항(R8)의 접속점이 저항(R6), 가변저항(VR1), 저항(R7) 및 다이드(D2)을 통해 그 수평펄스입력단자(HS)에 접속되며, 상기 브라운관(2)의 그리드가 저항(R9)을 통해 상기 가변저항(VR1)의 가변단자에 접속되어 구성된 휘도회로에 있어서, 상기 트랜지스터(TR1)의 베이스를 제너다이오드(ZD1) 및 저항(R10)을 통해 상기 가변저항(VR1)의 가변단자에 접속하여 구성된 것을 특징으로 하는 휘도변화 보상회로.
