Patent ID: 7956840

Claim:
An electro-optical device comprising: a plurality of scanning lines, a plurality of data lines blocked for every “m” (m is an integer of 2 or greater) columns, pixels provided corresponding to the scanning lines and the data lines and showing grayscale specified by data signals sampled to data lines when a scanning line is selected, image signal lines, a scanning line driving circuit which selects the scanning line in a predetermined order, a sampling signal output circuit which sequentially outputs a plurality of sampling signals, and a sampling circuit which has a sampling switches for each data lines and the sampling switches being connected to the corresponding data lines, the sampling circuit turning on the sampling switches to sample data signals supplied to “n” (n is an integer of 2 or greater) of the image signal lines, to the data lines, the blocks being grouped into “n” blocks, individual blocks in the same group corresponding to different image signal lines, and the sampling switches in the individual blocks being connected to corresponding image signal lines, a scanning control circuit which sequentially outputs a plurality of scanning control signals to the sampling circuit where one half of the plurality of scanning control signals are applied to odd numbered groups and another half of the plurality of scanning control signals are applied to even numbered groups, one sampling signal being supplied to two adjacent groups, when any one sampling signal is supplied, sampling switches in the same columns in “n” blocks belonging to one group of two groups corresponding to the sampling signal are simultaneously turned on, the scanning control circuit sequentially outputs 2m or more scanning control signals, and a first half of the 2m or more scanning control signals are provided to control the sampling switches in the odd numbered groups, and a second half of the 2m or more scanning control signals are provided to control the sampling switches of the even numbered groups.
