Abstract: In an LCD pixel, the pixel voltage is usually reduced after a gate line signal has passed. To compensate for this voltage reduction, the voltage applied to the charge storage capacitor in the pixel is increased from Vcom to Vcom1 after the gate line signal has passed. Voltage adjustment can be achieved by using two switching elements connected to the second end of the charge storage capacitor. One is activated by the gate line signal so that the applied voltage is equal to Vcom, and the other is activated by the next gate line signal so that the applied is increased to Vcom1. In a transflective LCD panel or a color LCD panel, each pixel is divided into two or three sub-pixels, each sub-pixel having a separate charge storage capacitor, a similar Vcom change is applied to each of the charge storage capacitors in the pixel.

Abstract: In a multi-domain vertical alignment liquid crystal display wherein a pixel that has two sub-pixels, an additional switching element is used to achieve a voltage differential between the electrode voltage potential in one sub-pixel and the other during and after the charge-sharing period. The electrodes in the sub-pixels are connected to each other through a charge-sharing capacitor and a controlling switching element, such as another transistor. Before the charge-sharing period, the controlling switching element is operated in a non-conducting state and the voltage potentials of the sub-pixel electrodes are substantially equal. During the charge-sharing period, the controlling switching element is operated in a conducting state to facilitate charge-sharing. The additional switching element is used to achieve the voltage differential more effectively and without additional capacitors.

The data signal is in a second state during a time interval after the pre-charged period is over and before the first scan signal enters a turn-on period. Voltage polarities of the first state and the second state are opposite. The pixel design can improve color shift and frame flicker.
