Abstract

본 발명은 쉬프트 클릭(SC)과, 좌/우 제어단자 및 양방향 데이타 전달 제어단자(DL,DR)를 구비하여 액정판넬의 각 도트셀을 구동시키는 액정판넬 드라이버에 제어신호를 보내는 LCD 콘트롤러에 있어서, 상하, 좌우 반전 입력신호에 따라서, 상기 드라이버의 SC에 보내는 제1,제2제어신호와DL,DR에 보내는 또다른 제1,제2제어신호를 2입력 1출력 멀티플렉서에 의해 선택적으로 제어신호가 구분 출력되도록 LCD 콘트롤러 출력단에 멀티플렉서가 설치된 것을 특징으로 하는 LCD 콘트롤러에 관한 것이며, 또한 쉬프트 클릭(SC)과 좌/우 제어단자(R/L) 및 양방향 데이타 전달 제어단자(DL,PR)를 구비하여 액정판넬의 각 도트셀을 구동시키는 LCD 드라이버와, 이에 연결된 액정판넬과, 상가한 구성의 LCD 콘트롤러를 구비하고, 이 LCD 콘트롤러는 상기 드라이버에 바로 연결시킨 것을 특징으로 하는 액정 프로젝터에 관한 것이다.The present invention is directed to an LCD controller having a shift click (SC), a left / right control terminal, and a bidirectional data transfer control terminal (DL, DR) for transmitting a control signal to a liquid crystal panel driver for driving each dot cell of the liquid crystal panel. And a second input one output multiplexer selectively outputs first and second control signals to the driver SC and another first and second control signals to DL and DR according to the up, down, left and right inverted input signals. The LCD controller is characterized in that the multiplexer is installed at the output of the LCD controller so that the output is separated, and the shift click (SC), the left and right control terminals (R / L) and the bidirectional data transfer control terminals (DL, PR) And an LCD driver for driving each dot cell of the liquid crystal panel, a liquid crystal panel connected thereto, and an LCD controller having a different configuration. The LCD controller is directly connected to the driver. It relates to a liquid crystal projector according to claim.
