  • Patent number: 8373633
    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.

  • Patent number: 8368685
    Abstract: In an image display apparatus of the invention, a signal input unit outputs a complex image signal, which has been converted to an easily-processed format, to a signal-for-display generator. The signal-for-display generator converts the complex image signal to a signal suitable for displaying at a display unit. An apparatus state-detector detects a state of the display apparatus. Based on apparatus state information input from the apparatus state-detector, an arithmetic unit calculates an amount of non-uniformity to be corrected, and outputs it to a non-uniformity corrector. Based on the non-uniformity correction amount corresponding to a position displayed at the display unit, the non-uniformity corrector corrects the image signal input from the signal-for-display generator, converts it to a signal format that can be used at the display unit, and outputs it.
