Abstract

텔레비젼수상기의 고압 안정화 출력 방법에 있어서, 화면밝기(휘도) 변화량에 따라 ABL 전압 증감을 이용하고, 고압 안정화의 ABL 검출, ABL 설정과 정전압에 의해 기준전압으로 바이어스를 걸어 ABL 전압 이상 출력과 접속후 수평편향 출력을 제어하여 거압 출력을 안정화되도록 구성됨.In the high-voltage stabilized output method of a television receiver, the ABL voltage is increased or decreased according to the change in brightness of the screen, and the ABL is detected by the high-pressure stabilization, biased to the reference voltage by the ABL setting and the constant voltage, and then connected to the abnormal output of the ABL voltage. It is configured to stabilize the high pressure output by controlling the horizontal deflection output.
