Patent ID: 7800574

Claim:
A liquid crystal display device for matrix driving to alternately drive pixels arranged in matrix, wherein a plurality of row electrodes extending in a horizontal direction of a display screen are made to be selectively active for each horizontal scanning period of images to be displayed; a plurality of column electrodes extending in a vertical direction of the display screen are supplied with respective pixel data which are correspond to the image and relevant to the horizontal scanning period while the pixel data have polarities alternating for each frame period of the images; and the pixel data have polarities alternating in the vertical direction spatially in a display area within the frame period, the device comprising: a plurality of storing means for storing the pixel data relevant to row electrodes having the same polarities, wherein the plurality of storing means comprises a first storing means and a second storing means; latch means to which the pixel data are transferred; and timing control means for controlling the timing such that the pixel data relevant to row electrodes having the same polarities are written in said plurality of storing means or said latch means, wherein matrix driving is performed in such a way that the device is successively sequencing on a time series a supply timing of pixel data for one row electrode and a supply timing of pixel data for the other row electrode having the same polarities as the pixel data for the one row electrode, and activates the relevant row electrode in response to each of the supply timings of the pixel data for the one and the other row electrodes; and said first storing means stores the pixel data on odd rows and said second storing means stores the pixel data on even rows, then said latch means stores pixel data on one row, after that said first storing means stores the pixel data on even rows and said second storing means stores the pixel data on odd rows.
