Patent ID: 7804548

Claim:
An electro-optical device comprising: 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 corresponding to intersections of the plurality of scanning lines and the plurality of data lines; 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 receives data signals corresponding to m pixels corresponding to the selected scanning line and the data lines belonging to the selected block and distributes the data signals 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 the selected block on the basis of the sampling signal, wherein the rotation circuit includes: a decoder which detects m combinations of logical levels of the one or more control signals; a multiplexer which distributes the data signals corresponding to the m pixels to the m image signal lines as m different signals according to the result detected by the decoder.
