ABSTRACT:
An electro-optic device comprising, a plurality of pixels corresponding to a plurality of scanning lines and a plurality of data lines a scanning-line drive circuit that selects the scanning lines in a predetermined order a block selection circuit that sequentially selects a block including m columns of data lines (m is an integer equal to or larger than 2 and smaller than the total number of the data lines); m image signal lines to which data signals are supplied and to which precharge signals of a predetermined voltage are supplied before the block is selected, the data signals each having a voltage corresponding to the gray-scale level of a pixel corresponding to a selected scanning line and a data line in a selected block; a sampling switch provided for each data line, wherein when the data signals are supplied to the m image signal lines, m sampling switches corresponding to the data lines in the block selected by the block selection circuit become conducting to sample the data signals; when the precharge signals are supplied to the m image signal lines, the sampling switches become conducting according to a predetermined control signal to sample the precharge signal on the data lines before the sampling switches sample the data signals; and short-circuiting switches that become conducting according to a predetermined second control signal and short-circuit at least m data lines in the block, after the percentage signals are sampled to the data lines by the precharge switch before the data signals are sampled to the data lines.
