Abstract

본 발명은 브라운관으로 입력되는 원색신호에 피크 리플 전압 또는 과도 레벨 전압으로 인하여 발생되는 퓨리티 칼라신호를 억제할 수 있도록 한 자동 색도 조절회로에 관한 것으로, R,G,B 3개의 원색신호를 브라운관의 각 캐도우드에 공급하였던 매트릭스화된 버퍼부에 색신호 조절수단을 병렬로 접속하여서 색신호 증폭부를 거쳐 출력되는 전압의 이장유무에 관계없이 색신호 조절부를 구동하게 하여 항상 일정한 크기의 원색신호를 브라운관으로 출력할 수 있도록 하므로써, 양질의 화면을 제공할 수 있게 하는 유용한 발명이다.The present invention relates to an automatic chromaticity control circuit capable of suppressing a purity color signal generated due to a peak ripple voltage or a transient level voltage to a primary color signal input to a CRT. The color signal adjusting means is connected in parallel to the matrixed buffers supplied to the respective modules so that the color signal adjusting unit is driven regardless of whether or not the voltage is outputted through the color signal amplifier. It is a useful invention to make it possible to provide a high quality screen.
