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.
