发明名称 Drive method for liquid crystal display device
摘要 A driving method is described for a liquid crystal display device of the active matrix type which includes a pair of substrates and a liquid crystal disposed between the substrates so as to form a matrix of pixels provided with a plurality of pixel electrodes arranged in rows and columns, a plurality of row electrodes and a plurality of column electrodes, respectively, for applying a voltage to the pixels via the pixel electrodes, and a plurality of active elements each provided to a pixel and connected to a pixel electrode, a row electrode and a column electrode, respectively. The driving method includes a field-inversion drive scheme wherein the liquid crystal display device is driven while inverting a polarity of voltage applied to each pixel every picture scanning field. The voltage applied to each pixel is corrected based on a voltage to be applied to a column electrode connected to the pixel for a period from a time of selecting an active element at the pixel in a field period to a time of selecting the active element in a subsequent field period.
