Abstract:
1. A driving method for a liquid crystal device that causes pixels at intersections of scanning electrodes and signal electrodes to perform gray-scale display based on pieces of gray-scale data, each piece being formed of a plurality of bits, comprising: selecting three of the scanning electrodes in accordance with a predetermined scanning pattern having three rows and n columns (n is an integer greater than or equal to 3) n times in a vertical scanning period; at each selection, applying selection voltages in accordance with three column elements of the scanning pattern, the column elements corresponding to the selection, to the three scanning electrodes, respectively; in each selection period in which three of the scanning electrodes are selected, comparing bits of a bit string in accordance with the column elements of the scanning pattern, the column elements corresponding to the selection, with the corresponding bits of each of a plurality of bit strings, each bit string being formed of a bit in each position of the pieces of gray-scale data for the three pixels at the intersections of the signal electrode and the three scanning electrodes, and generating conversion data in accordance with comparison results; and in the selection period, applying a first voltage to the signal electrode for a period of duration in accordance with the conversion data, and applying a second voltage differing from the first voltage to the signal electrode for a remaining period.
