Abstract

본 발명은 액정표시장치의 구동방법에 관한 것으로서, 특히 데이타전압에 의해 발생하는 수평 크로스토크(Crosstalk)현상을 방지하도록 한 액정표시장치의 구동 방법에 관한 것이다.
상기와 같은 목적을 달성하기 위해 본 발명에 따른 액정표시장치의 구동방법은 게이트신호의 전압펄스에 의해 액정표시장치를 선순차 구동하는데 있어서, 데이타신호의 전압펄스의 인가시간보다도 짧으며, 데이타신호의 최고전압펄스에서 발생하는 공통전극신호의 왜곡시간을 제외한 시간동안 상기 게이트신호의 전압펄스를 인가함을 특징으로 한다.
따라서, 본 발명에 따른 액정표시장치의 구동방법은 공통전극신호의 왜곡에 의해 발생되는 수평 크로스토크를 제거하므로 화질을 향상시키는 효과가 있다.
