Patent ID: 8159431

Claim:
An electrooptic device comprising: a plurality of scanning lines; a plurality of m image signal lines; m connecting signal lines provided in a one-to-one correspondence with the m image signal lines, each connecting signal line being connected to the corresponding image signal line to feed a data signal; a plurality of data lines blocked by m lines, m data lines in one block being provided in a one-to-one correspondence with the m image signal lines; a scanning-line driving circuit that selects the plurality of scanning lines in a predetermined order; a block selecting circuit that outputs sampling signals indicative of the selection of the blocks in a predetermined order during a period selected for one scanning line; a sampling switch provided for each of the plurality of data lines, each sampling switch being turned on between the corresponding image signal line and data line when the sampling signal selects a block; and pixels provided at the intersections of the plurality of scanning lines and the plurality of data lines, each pixel becoming a gray level corresponding to the data signal sampled to the data line when the scanning line is selected; wherein: the block selecting circuit has a plurality of unit circuits whose output terminals are each connected to the input terminal of the following stage, the unit circuits each outputting a pulse provided to the input terminal from the output terminal with a predetermined delay and outputting a sampling signal according to the pulse provided to the input terminal and the output terminal; and the connecting signal lines intersect an interconnect signal line connecting the output terminal of one unit circuit and the input terminal of the unit circuit in the following stage.
