Patent ID: 7030848

Claim:
A liquid crystal display comprising: an array substrate having a plurality of gate lines and a plurality of source lines arranged to cross each other, pixel electrodes provided in matrix, and switching devices respectively provided as corresponding to the pixel electrodes, for switching between a conductive state and a non-conductive state between the pixel electrodes and the source lines according to scan signals supplied through the gate lines to allow writing of video signals supplied through the source lines to the pixel electrodes; an opposing substrate disposed opposite to the array substrate; a liquid crystal layer disposed between the array substrate and the opposing substrate and containing filled liquid crystal; a counter electrode provided on one of the opposing substrate and the array substrate, for generating potential difference between the counter electrode and the pixel electrodes, thereby driving the liquid crystal; and an illuminating device including a light source for emitting lights of a plurality of colors, wherein one frame period of the video signals is composed of a plurality of sub-frame periods, the illuminating device is controlled to emit light of one of the plurality of colors to the liquid crystal layer in each sub-frame period, and predetermined signals are written onto the pixel electrodes in the order of first writing and second writing in at least one sub-frame period, for allowing video signals associated with the at least one sub-frame period to be supplied to the pixel electrodes to cause the liquid crystal to be driven to thereby allow image corresponding to the video signals to be displayed, and first non-video signals near voltage for black display and second non-video signals near voltage for white display are written to at least part of the pixel electrodes in this order in the first writing, and the video signals are written to the pixel electrodes in the second writing.
