Abstract

본 발명은 모니터가 절전모드로 동작하는 경우에 내부회로로 공급되는 전압을 차단해 줌으로써, 불필요한 회로동작으로 인해 소모되는 전력을 감소시키기 위하여, 각 모드에서 비디오 보드 구동전압단에 발생하는 전위를 전압 분배기로 전압강하시켜 마이크로 프로세서에 인가하여 모니터에 모드변환이 생길 경우, 이를 검출한 신호로 수평, 수직 편향부의 동작을 제어할 수 있도록 구현한 자동 절전회로에 관한 기술이다.The present invention cuts off the voltage supplied to the internal circuit when the monitor is operating in the power saving mode, so as to reduce the power consumed due to unnecessary circuit operation. The present invention relates to an automatic power saving circuit implemented to control the horizontal and vertical deflection units using a signal detected when a mode change occurs in a monitor by applying a voltage drop to a microprocessor.
