Abstract:
1. A driving method for a liquid crystal display device, the method comprising: selecting simultaneously a plurality of lines of row electrodes in a liquid crystal display device comprising a plurality of row electrodes and a plurality of column electrodes; and applying predetermined voltages to the selected lines of the row electrodes during a selection period, wherein the selection period of at least a display frame is divided into divided selection periods such that any two divided selection periods of the selection period have a first predetermined ratio, which is different than 1, the predetermined voltages are applied to the lines of row electrodes during the divided selection periods, and column electrodes are driven with a voltage pattern by reducing a number of changes of voltage levels in each of the divided selection periods, and two selection periods corresponding to two continuous display frames have a second predetermined ratio, which is different than 1.
