Patent ID: 7847776

Claim:
A drive circuit for driving an electro-optical device that includes a plurality of data lines and a plurality of scanning lines extending to intersect each other and a plurality of pixel portions which are connected to the data lines and the scanning lines and which constitute a display surface, the drive circuit comprising: a scanning-line driving unit that supplies scanning signals to the plurality of scanning lines; and a data-line driving unit that supplies image signals to the plurality of data lines, wherein the scanning-line driving unit and the data-line driving unit drive, in a surface inversion manner, 2M (where M is a natural number greater than or equal to 2) partial surfaces that result from dividing the display surface by an imaginary division line that extends in a direction in which the scanning lines extend, each partial surface including n (where n is a natural number greater than or equal to 2) scanning lines and each partial surface having a designation as either an odd partial surface or an even partial surface, wherein the scanning-line driving unit and the data-line driving unit drive, in a first cycle, the pixel portions in the odd partial surfaces of the 2M partial surfaces with respect to a direction in which the data lines extend, and drive, in a second cycle that is complementary to the first cycle, the pixel portions in the even partial surfaces of the 2M partial surfaces, wherein the scanning-line driving unit includes: an output control section having logical circuits, each logical circuit having an output connected to one of the scanning lines, an input for receiving a pulse signal, and an input for receiving an enable signal, and a shift register that outputs pulse signals to the logical circuits to simultaneously select one scanning line from each of the odd and the even partial surfaces during each of a plurality of output periods, wherein within each of the plurality of output periods, 2M enable signals (where M is a natural number greater than or equal to 2) are sequentially supplied to enable, one at a time, each of the simultaneously selected scanning lines, wherein a sequence of the 2M enable signals during each of the plurality of output periods is different from both a sequence of the 2M enable signals of the output period immediately preceding and the output period immediately following the each of the plurality of output periods, and wherein the sequences of the 2M enable signals change in a cyclical manner.
