Driving method of liquid crystal display

Claim 1

A method of driving a liquid crystal display, said liquid crystal display including a plurality of scan electrodes extending in parallel along a row direction; a plurality of signal electrodes extending in parallel along a column direction perpendicular to said row direction; a plurality of pixels arranged at intersections of said scan and signal electrodes in a matrix and connected to said scan and signal electrodes to operate in accordance with signals supplied therefrom, said pixels being allotted respectively three primary colors for color display such that each one of said colors repeatedly appears with the other two colors in between in a fixed order along each row, each pixel of one of said colors along one scan electrode being located, with respect to said row direction, between pixels of other colors along an adjacent row; a scan electrode driving circuit connected to said scan electrodes for scanning and activating said scan electrodes in sequence; a signal electrode driving circuit for sequentially supplying data signals to said pixels indicative of image data to be displayed through said signal electrodes, along one of said scan electrodes being activated by said scan electrode driving circuit; said method of driving said liquid crystal display comprising the following steps: scanning said rows of said pixels connected to said scan electrodes by activating one of said scan electrodes in sequence; and supplying data signals indicative of said image data through said signal lines in synchronism with said scanning, wherein the polarity of data signals supplied to said pixels allotted to one of said colors along one row is opposite to the polarity of the other two colors along the same row, and wherein the polarity of said pixels of each color along one row is opposite to that along an adjacent row.

Claim 2

A method of driving a liquid crystal display, said liquid crystal display including a plurality of scan electrodes extending in parallel along a row direction; a plurality of signal electrodes extending in parallel along a column direction perpendicular to said row direction; a plurality of pixels arranged at intersections of said scan and signal electrodes in a matrix and connected to said scan and signal electrodes to operate in accordance with signals supplied therefrom, said pixels being allotted respectively three primary colors for color display such that each one of said colors repeatedly appears with the other two colors in between in a fixed order along each row, each pixel of one of said colors along one scan electrode being located, with respect to said row direction, between pixels of other colors along an adjacent row; a scan electrode driving circuit connected to said scan electrodes for scanning and activating said scan electrodes in sequence; a signal electrode driving circuit for sequentially supplying data signals to said pixels indicative of image data to be displayed through said signal electrodes, along one of said scan electrodes being activated by said scan electrode driving circuit; said method of driving said liquid crystal display comprising the following steps: scanning said rows of said pixels connected to said scan electrodes by activating one of said scan electrodes in sequence; and supplying data signals indicative of said image data through said signal lines in synchronism with said scanning, wherein the polarity of data signals supplied to said pixels allotted to one of said colors along one row is opposite to the polarity of the other two colors along the same row, and wherein the polarity of said pixels of each color along one row is opposite to that along an adjacent row.
