Abstract

본 발명은 DPMS(Display Power Management System)에 의거하여 모니터의 전력을 관리하는 모니터의 전력관리장치에 관한 것으로, 사용자가 컴퓨터의 사용을 중단하는 경우 모니터의 전력 사용을 절감시키도록 관리하는 모니터의 전력 관리 장치에 관한 것이다.The present invention relates to a power management apparatus for a monitor which manages power of a monitor based on a DPMS (Display Power Management System). More particularly, the present invention relates to a monitor power management apparatus for monitoring power consumption of a monitor Management device.

종래의 전력 관리 장치에서는 모니터를 오프모드로 운용하기 위해서 레귤레이터 구동전원 공급회로(16)와 마이콤 전원공급회로(17)를 사용하고 있기 때문에 회로제작 비용이 증가되고, DPMS 구동시에 트랜스포머(12)와 연동되도록 되어 있기 때문에 회로 구성이 어렵고 동작 신뢰성이 저하되는 문제점이 있다.In the conventional power management apparatus, since the regulator driving power supply circuit 16 and the micom power supply circuit 17 are used for operating the monitor in the off mode, the circuit manufacturing cost is increased and the power consumption of the transformer 12 There is a problem that the circuit configuration is difficult and the operation reliability is deteriorated.

본 발명은 모니터를 오프모드로 운용하는 경우에 레귤레이터(11)와 마이컴(18)에 동작 전원을 공급하기 위한 별도의 전원공급회로를 사용하지 않아도 되고, DPMS 구동시에 트랜스포머(12)와 연동하지 않더라도 DPMS의 기능을 수행하므로, 회로 제작 비용을 감소시킴과 동시에 동작 신뢰성을 향상시키게 된다.The present invention does not require the use of a separate power supply circuit for supplying operating power to the regulator 11 and the microcomputer 18 when the monitor is operated in the off mode, The function of the DPMS is performed, so that the circuit manufacturing cost is reduced and the operation reliability is improved.
