Abstract

본 발명은 초기동작 부호부를 포함하는 전원 안정화 회로를 모니터의 메인 보드 상에 구현함으로써, 전력소모를 감소시키기 위해 모니터가 정상상태에서 절전모드로 또는 절전모드에서 정상상태로 전환된다 하더라도 모든 내부회로의 동작을 제어하는 마이크로 프로세서에 항상 안정된 전원을 공급할 수 있게 되어, 모니터 내부회로의 동작을 안정화시킨 것에 관한 기술이다.The present invention implements a power stabilization circuit including an initial operation code on the main board of the monitor, so that all internal circuits of the internal circuit are reduced even if the monitor is switched from the normal state to the power saving mode or from the power saving mode to reduce the power consumption. It is a technique related to stabilizing the operation of the monitor internal circuit by providing a stable power supply to the microprocessor that controls the operation at all times.
