Abstract

본 발명은 주사선(7)에 스위칭소자(14)를 연결하여 주사선에 주사전압이 인가되면 주사선에 전압이 인가되고 주사전압이 인가되지 않는 비선택시에는 주사선이 전기적으로 플로트되는 액정표시소자 구동방법에 대한 것이다.The present invention relates to a method of driving a liquid crystal display device in which a switching element 14 is connected to the scan line 7 so that a scan voltage is applied to the scan line and the scan line is electrically floated when the scan line is not selected. It is about.

그러나 이 방법을 액정표시소자에 적용할 경우 신호선(6)의 데이타 전압에 의하여 발생된 신호선의 전하가 비선택 주사선의 반대극 전하를 유도하여 비선택 주사선에도 액정층(5)에도 전장이 인가되는 현상이 발생되므로 화질이 떨어진다.However, when this method is applied to the liquid crystal display device, the electric charge of the signal line generated by the data voltage of the signal line 6 induces the opposite charge of the non-selected scan line, so that the electric field is applied to the non-selected scan line and the liquid crystal layer 5. As the phenomenon occurs, the image quality is reduced.

본 발명은 이러한 문제점을 해결하고자 인접 신호선간에 신호전압의 극성을 반대로 인가하여 비선택 주사선에서의 인가되는 전압을 줄여 고화질의 화면을 얻을 수 있었다.In order to solve this problem, the polarity of the signal voltage is applied to the adjacent signal lines in opposite directions, thereby reducing the voltage applied to the non-selected scan lines, thereby obtaining a high quality screen.

본 발명의 액정표시소자는 제조공정이 간단하고 또한 단순메트릭스 방식에서도 최대한 크로스토크 줄임으로써 고화질을 얻을 수 있어 휴대용 TV나 노트북컴퓨터의 정보표시소자로 이용할 수 있다.The liquid crystal display device of the present invention can be used as an information display device of a portable TV or a notebook computer because the manufacturing process is simple and a high quality can be obtained by reducing crosstalk as much as possible even in a simple matrix method.
