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.
