  • Pixel structure for liquid crystal display
    Patent number: 7433007
    Abstract: The present invention builds a metal electrode that is controlled by the common electrode in each pixel cell. During operation, a voltage is first applied to this metal electrode to transform the liquid crystal molecule over this metal electrode from the splay state to the bend state. Next, a voltage is applied to the pixel electrode to transform the liquid crystal molecule in the whole pixel region from the splay state to the bend state.
