Electro-optical device, method of driving electro-optical device, driving circuit, and electronic apparatus
A method of driving 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 is provided. The method includes: selecting the plurality of scan lines in a predetermined order; dividing a period of time, when one of the scan lines is selected, into a first period and a second period; selecting m (where m is an integer greater than or equal to 2) lines from one of an odd group and an even group consisting of odd-numbered and even-numbered data lines, respectively, in the first period; selecting m data lines from the other of the odd group and the even group of data lines in the second period; and sampling data signals supplied to m image signal lines and supplying the sampled data signals to the selected m data lines.
