  • LIQUID CRYSTAL DISPLAY PANEL AND DRIVING METHOD THEREOF
    Publication number: 20090295703
    Abstract: A liquid crystal display panel includes a plurality of pixels and each of the pixels includes a first sub-pixel and a second sub-pixel. The first sub-pixel and the second sub-pixel individually load a source voltage according to a first gate pulse and a second gate pulse, respectively. The second sub-pixel includes a first storage capacitor and a first compensation capacitor. The first compensation capacitor charges or discharges to a predetermined voltage before performing charge neutralization with the first storage capacitor according to a second gate pulse.
