Abstract
A multiplex driving method and driving apparatus are provided for a liquid crystal display device having a liquid crystal layer disposed between a pair of substrates, a plurality of row electrodes arranged on one of the substrates and a plurality of column electrodes arranged on the other substrate, the plurality of row electrodes being arranged in plural groups. A portion of the row electrodes are simultaneously selected a within a selection period in which the selection period is divided into a plurality of intervals. A weighted voltage is applied in accordance with desired display data in each of the plurality of intervals to achieve a gray scale display.
