    摘要: A pixel circuit includes a first sub-pixel and a second sub-pixel. The first sub-pixel is coupled to a scan line and a data line, so as to determine whether to be enabled according to a first scan signal transmitted on the scan line, and whether to be driven according to a data signal transmitted on the data line. The second sub-pixel is coupled to the scan line, so as to determine whether to be enabled according to the first scan signal. The data signal is in a first state when the first scan signal is in a pre-charged period. 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.

    摘要: 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.
