Abstract

본 발명은 액정표시장치를 이용한 와이드비젼 구현방법에 관한 것으로, 16 : 9 액정판넬을 구동하기 위한 소스 구동부에 1 수평주사기간 중 일정위치에서 주파수를 다른 값으로 바꾸어 1수평주사기간동안 2개 이상의 주파수값을 갖는 샘플링 클럭신호가 인가되도록 하며, 상술한 바와 같은 방법으로 화면을 복수개로 분할하여 화면 중앙측의 샘플링 클럭 주파수를 좌,우측 보다 높게함으로써 주요화면부분의 데이타 손실을 거의 방지하고 전체적으로도 다량의 데이타의 손실을 방지함으로써 양질의 와이드 비전 화면을 제공할 수 있는 효과가 있다.The present invention relates to a method for implementing a wide vision using a liquid crystal display device, wherein the source driver for driving a 16: 9 liquid crystal panel is changed to a different value at a predetermined position during one horizontal scanning period, and thus two or more during one horizontal scanning period. A sampling clock signal having a frequency value is applied, and the screen is divided into a plurality of screens as described above, and the sampling clock frequency at the center of the screen is made higher than the left and right sides to almost prevent data loss of the main screen part and also as a whole. By preventing the loss of large amounts of data, it is possible to provide a good quality wide vision screen.
