Abstract

본 발명은 액정표시판넬 구동용 분할전압을 발생하는 분할저항의 소비전류 감소 회로에 관한 것으로, 액정표시판넬 컨트롤러에 분할전압 발생회로와 분할전압 발생회로의 전류패스를 연결/차단하는 스위치 회로를 내장하거나, 액정표시판넬 컨트롤러에 분할전압 발생회로는 내장하고 분할전압 발생회로의 전류패스를 연결/차단하는 스위치 회로는 외부에 구성하여, 파워다운모드 시에 분할전압 발생회로의 전류패스를 차단하도록 하므로 액정표시판넬 구동회로의 불필요한 소비전류의 발생을 완전히 차단 하는 효과가 있다.The present invention relates to a circuit for reducing a current consumption of a divided resistor for generating a divided voltage for driving a liquid crystal display panel, and includes a switch circuit for connecting / blocking current paths of the divided voltage generating circuit and the divided voltage generating circuit to a liquid crystal display panel controller. Alternatively, the switch circuit for integrating the split voltage generator circuit in the liquid crystal display panel controller and connecting / blocking the current path of the split voltage generator circuit can be configured externally to cut off the current path of the split voltage generator circuit in the power down mode. There is an effect to completely block the generation of unnecessary current consumption of the liquid crystal display panel drive circuit.
