Abstract:
A pixel in a liquid crystal display panel comprises a first sub-pixel area having a first sub-pixel electrode and a second sub-pixel area having a second sub-pixel electrode. Each sub-pixel electrode is associated with a capacitor. When a gate-line signal and a data voltage is provided to the pixel, the voltage level on the first sub-pixel electrode is substantially equal to or slightly higher than the voltage level on the second sub-pixel electrode and the capacitor associated with each sub-pixel electrode is charged. When the gate-line signal has entirely passed on partially passed, a circuit element causes the capacitor associated with the second sub-pixel electrode to transfer its charge to another capacitor, resulting in a reduction of the voltage level on the second sub-pixel electrode.
