Abstract:
1. A method of driving an electro-optical device having image-signal lines and a plurality of pixels arranged to correspond to intersections between a plurality of scanning lines and a plurality of data lines, the plurality of data lines being grouped into a predetermined number of blocks comprising a predetermined number of data lines, the method comprising: precharging one of the data lines of a block to a first voltage during a first period and precharging the one of the data lines to a second voltage during a second period after the first period; precharging another of the data lines of the block to a first voltage during a third period and precharging the other of the data lines to a second voltage during a fourth period after the third period, wherein: the first period and the third period starting simultaneously, the third period being a different duration than the first period, the fourth period being a different duration than the second period, and a timing when the first voltage is switched to the second voltage in the one of the data lines of the block being later from a timing when the first voltage is switched to the second voltage in the other of the data lines of the block, selecting the plurality of scanning lines during a selection period after the precharging; and sampling image signals to the plurality of data lines through the image-signal lines simultaneously; and supplying the image signals to the pixels via the plurality of data lines during the selection period.
