  • Patent number: 8248338
    Abstract: To enable a common inversion driving even in an LCD having a large size and a high definition. A common capacitance is significantly reduced by making most of scanning lines in a floating state during the common inversion. In addition, the timing for floating the scanning lines is changed depending on the polarity of the common potential. Specifically, if a pixel switching element is an N channel type, the scanning lines are floated when the common potential is high. If the pixel switching element is a P channel type, the scanning lines are floated when the common potential is low.
