Abstract

본 발명은 픽셀전극의 전압강하를 보상하는 TFT-LCD 구동방법에 관한 것이다. 상기와 같은 목적을 달성하기 위해 본 발명에 따른 액정표시장치의 구동방법은 공통전극의 전압에 의해 액정표시장치를 구동하는데 있어서, 게이트 구동 펄스에 의해 액정의 픽셀전압이 상승할 때 상기 공통전극의 전압을 소정변위로 상승시키고, 상기 액정의 픽셀전압이 최대로 충전될 때 공통전극의 전압을 상승된 소정변위로 하강시킴을 특징으로 한다. 따라서, 액정에서 빠져나간 전압을 보상하여 30Hz의 플리커현상을 방지하므로서 액정 디스플레이의 회절을 향상시킬 수 있는 효과가 있다.The present invention relates to a TFT-LCD driving method for compensating a voltage drop of a pixel electrode. According to another aspect of the present invention, there is provided a method of driving a liquid crystal display (LCD) device including driving a liquid crystal display device with a voltage of a common electrode, The voltage is raised to a predetermined displacement and the voltage of the common electrode is lowered to the raised predetermined displacement when the pixel voltage of the liquid crystal is fully charged. Therefore, it is possible to improve the diffraction of the liquid crystal display by preventing the flicker phenomenon of 30 Hz by compensating the voltage exiting from the liquid crystal.
