Abstract
본 발명은 모니터의 전원오프시 안정화회로에 관한 것으로서, 특히 모니터의 구동 전원을 오프시킬 경우 잔상화면을 제거하여 음극선관을 보호하고 화면의 밝음현상을 방지할 수 있도록 하는 모니터의 전원오프시 안정화회로에 관한 것이다.The present invention relates to a stabilization circuit when the monitor is powered off, and in particular, when the driving power of the monitor is turned off, the stabilization circuit when the monitor is turned off to protect the cathode ray tube by preventing the afterimage screen, and to prevent the brightness of the screen It is about.
이를 위하여 플라이백 트랜스포머로 부터 출력되는 고압에 의해 음극선관를 동작시키는 모니터 구동회로에 있어서, 모니터에 전원 인가시 소정전압을 출력시키는 전원부, 상기 전원부의 출력전압에 따라 구동되어 스위치 기능을 갖고 소정의 제어신호를 발생하는 드라이브회로, 상기 드라이브회로의 출력신호에 의해 음극선관에 B+ 전원을 인가하는 B+ 공급부를 구비하여 전원 오프시 화면의 잔상을 제거하도록 한 것이다.To this end, in the monitor driving circuit for operating the cathode ray tube by the high voltage output from the flyback transformer, the power supply unit for outputting a predetermined voltage when the power is applied to the monitor, driven according to the output voltage of the power supply unit has a switch function and predetermined control A drive circuit for generating a signal and a B + supply unit for applying B + power to the cathode ray tube by an output signal of the drive circuit are provided to remove an afterimage on the screen when the power is turned off.
