Description

색온도 자동 조정 회로
본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음
제1도는 본 발명의 일실시예를 도시하는 색온도 자동 조정회로내의 피드백계의 블록도.
제2도는 제어 전압 E0과 이득 Ga의 타이밍 파형도.
제3도는 음극 전류의 입상 특성의 그래프.

Claims (1)

  1. 칼러 수상관을 드라이브하는 각 색채널의 증폭기의 특성을, 상기 칼러 수상관의 음극 전류치에 의해서 제어하고, 상기 컬러 수상관이 적정한 발색온도로 되도록 제어할 수가 있는 색온도 자동 조정회로에 있어서, 상기 각 색채널의 증폭기의 특성을 제어하는 피드백 제어계의 회로에, 전원이 온으로 되었을 때에 상기 증폭기의 이득을 저하시키고, 소정의 시정수로 이득을 회복시키는 제어 전압 발생회로가 설치되어 있는 것을 특징으로 하는 색온도 자동 조정 회로.
    ※참고사항: 최초출원 내용에 의하여 공개하는 것임.
