Patent ID: 7808467

Claim:
An electro-optical device having a plurality of pixels which are formed to correspond to intersections between a plurality of scan lines and a plurality of data lines and each of which exhibits a grayscale of output light corresponding to a data signal sampled and supplied to the corresponding data line when the corresponding scan line is selected, comprising: a scan line driving circuit that selects the plurality of scan lines in a predetermined order; and a data line driving circuit that: divides the plurality of data lines into blocks to form blocks each consisting of 2m data lines where m is an integer greater than or equal to 2 and less than a total number of odd-numbered data lines or even-numbered data lines, divides a period of time, when a first scan line is selected, into a first period and a second period; sequentially specifies at least two blocks in each of the first and second periods when the first scan line is selected, in the first period when the first scan line is selected, simultaneously selects m data lines from an odd group consisting of odd-numbered data lines belonging to the specified block; in the second period when the first scan line is selected, simultaneously selects m data lines from an even group consisting of even-numbered data lines belonging to the specified block; divides a period of time, when a second scan line next to the first scan line is selected, into a first period and a second period; sequentially specifies at least two blocks in each of the first and second periods when the second scan line is selected, in the first period when the second scan line is selected, simultaneously selects m data lines from the even group consisting of even-numbered data lines belonging to the specified block; in the second period when the second scan line is selected, simultaneously selects m data lines from the odd group consisting of odd-numbered data lines belonging to the specified block; and samples data signals supplied to m image signal lines and supplies the sampled data signals to the selected m data lines.
