Embodiment Construction
[0015] Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.
[0016] In an exemplary embodiment of the present invention, a liquid crystal display device adopts a vertical alignment mode of liquid crystals and can improve side visibility. In the vertical alignment mode, liquid crystal molecules are vertically distributed when no electric field is applied to the liquid crystal layer. When a voltage is applied to the liquid crystal layer, the liquid crystal molecules are vertically aligned with respect to the electric field. For example, a super-pattemed vertical alignment (S-PVA) mode divides one pixel into two sub-pixels, wherein the charging rate of the first liquid crystal capacitor for the first sub-pixel is the same as that for the second sub-pixel. The charging rates of the second liquid crystal capacitors of the pixels are different. According to an exemplary embodiment of the present inven...

The present invention discloses a liquid crystal display device comprising a time sequence controller, a data driver, a grid driver and a liquid crystal panel. The time sequence controller receives image data signal to output fist control signal, the second control signal, and data signal corresponding to the image data signal. The data driver responding to the first control signal and the data signal, outputs a first gray signal and second gray signal having different gray scale. The grid driver responding to the second control signal, outputs grid signal. The liquid crystal panel comprises a plurality of pixels aligned by matrix, and displays image responding to the first gray scale signal and the second gray scale signal and grid signal. The liquid crystal panel comprises a first sub pixel, a first gray scale signal and a second gray scale are alternatively applied on the first pixel; a second pixel, the first gray scale signal is applied on the second sub pixel.
Description
[0001] This application claims priority from Korean Patent Application No. 2006-31940 filed on Apr. 7, 2006, the contents of which are hereby incorporated by reference in their entirety. technical field [0002] The present invention relates to a display device, more specifically, to a liquid crystal display device capable of improving its display quality and a method for driving the liquid crystal display device. Background technique [0003] A liquid crystal display device includes two substrates bonded to each other while forming a predetermined space therebetween, and a liquid crystal layer interposed between the two substrates. The liquid crystal display device applies an electric field to align liquid crystal molecules of the liquid crystal layer to control polarization of incident light, thereby displaying an image. [0004] In a liquid crystal display device using a large-sized liquid crystal panel, an image exhibits ...
