Publication number: 20070091044Abstract: In a liquid crystal display, a liquid crystal panel includes a plurality of pixels. Each of the pixels has a plurality of subpixels corresponding to a red, a green and a blue and is arranged along data lines. The subpixels are formed in pixel regions, which are defined by the data lines and gate lines. First groups of the subpixels are connected to an adjacent left data line and second groups of the subpixels are connected to an adjacent right data line. The data lines are driven by a column inversion driving method such that image data applied to the adjacent data lines have different polarities. Thus, the screen-defects are reduced when the liquid crystal panel is driven by the dot inversion method.Type: ApplicationFiled: October 18, 2006Publication date: April 26, 2007Inventors: Haeng-Won Park, Seung-Hwan Moon, Nam-Soo Kang, Yong-Soon Lee
