Patent attributes
An electro-optical device includes: a plurality of scanning lines; a plurality of data lines which are divided into blocks each composed of m data lines (m is an integer equal to or larger than 2); pixels which are provided at intersections of the plurality of scanning lines and the plurality of data lines and each of which emits light at a gray-scale level designated by a data signal sampled to the data line when the scanning line is selected; a scanning line driving circuit which selects at least one of the scanning lines in a horizontal scanning period; a sampling signal output circuit which outputs sampling signals for sequentially selecting the blocks in the horizontal scanning period; a rotation circuit which inputs the data signals to m pixels corresponding to the selected scanning line and the data lines belonging to the selected block and distributes the input data signals corresponding to the m pixels to m image signal lines according to a correspondence prescribed by one or more predetermined control signals; and sampling switches each of which is provided to the data line and samples the data signals distributed to the m image signal lines to the m data lines belonging to one block on the basis of the sampling signal.
