Abstract

이 발명은, 수직편향코일(V1, V2)에 직렬 연결된 코마프리코일(CF1, CF2)과, 상기 코마프리코일(CF1, CF2)에 병렬 연결된가변저항(VR1)으로 구성된 미스컨버젼스 보정회로에 있어서; 상기 코마프리코일(CF1, CF2)과 가변저항(VR1) 사이에 분할보정용 가변저항(VR2, VR3)을 병렬로 접속한 후, 상기 가변저항(VR2, VR3)에 복수개의 다이오드(D1~D4)를 직렬로 연결하여 상기 가변저항(VR1, VR2, VR3)을 선택적으로 조정하여 코마프리코일(CF1, CF2)에 흐르는 전류량을 제어함으로써 수직편향자계 상하 언발란스(YH)를 보정하도록 한 미스컨버젼스 보정회로에 관한 것이다.The present invention relates to a misconvergence correction circuit comprising coma precoils CF 1 and CF 2 connected in series to vertical deflection coils V 1 and V 2, and a variable resistor VR 1 connected in parallel to the coma pre coils CF 1 and CF 2. ; After the split compensation variable resistors VR2 and VR3 are connected in parallel between the coma precoil CF1 and CF2 and the variable resistor VR1, a plurality of diodes D1 to D4 are connected to the variable resistors VR2 and VR3. Is connected in series to selectively adjust the variable resistors VR1, VR2, and VR3 to control the amount of current flowing through the coma pricoil CF1 and CF2 to correct the vertical unbalanced up and down unbalance (Y H ) It is about a circuit.
