  • Publication number: 20070164957
    Abstract: A multi-domain LCD panel includes data lines, scan lines and pixels. Each pixel includes first and second sub-pixels respectively having first and second storage capacitors. A first data switch is selectively coupled to a first terminal of the first capacitor and one of the data lines. A second data switch is selectively coupled to a first terminal of the second capacitor and one of the data lines. First and second bias lines are respectively coupled to second terminals of the first and second capacitors. When a corresponding scan line is enabled, the first and second data switches turn on such that a signal on the data line is transmitted to the first and second sub-pixels. After the scan line is disabled, levels of the first and second bias lines are changed such that pixel voltages of the first and second sub-pixels differ from each other.

  • Publication number: 20070121048
    Abstract: A multi-domain vertically aligned liquid crystal display includes an active element array substrate, an opposite substrate, and a liquid crystal layer disposed between the two substrates. The active element array substrate has a plurality of pixel units. Each pixel unit has a pixel electrode and the pixel electrode includes a first alignment pattern and a second alignment pattern. The opposite substrate includes a plurality of common electrodes and each common electrode includes a third alignment pattern and a fourth alignment pattern. The liquid crystal layer proximal each pixel unit is divided into a first domain set and a second domain set, wherein the first alignment pattern and the third alignment pattern correspond to the first domain set, and the second alignment pattern and the fourth alignment pattern correspond to the second domain set.

  • Publication number: 20060033727
    Abstract: A pixel signal for a pixel has an initial voltage during a frame period. The pixel signal is driven from the initial voltage to an intermediate voltage larger than the initial voltage during the frame period, and the pixel signal is maintained at the intermediate voltage for a time interval. After the time interval, the pixel signal is driven from the intermediate voltage to a target voltage larger than the intermediate voltage during the frame period.
