Patent ID: 7518590

Claim:
A driving circuit for an electro-optical device that drives an electro-optical device having, on an image display region on a substrate, a plurality of data lines and a plurality of scanning lines, and a plurality of pixel units electrically connected to the scanning lines and the data lines, the driving circuit for an electro-optical device comprising: a scanning line driving circuit that, with respect to a plurality of partial regions, which are obtained by dividing the image display region by division lines along the scanning lines, supplies scanning signals alternately to the scanning lines in the different partial regions, such that supplying a scanning signal to a first partial region is immediately followed by supplying another scanning signal to a second partial region before sending any scanning signal to the first partial region again, the first and second partial regions being different partial regions; and an image signal supply circuit that generates image signals based on display data and supplies the image signals to the plurality of data lines, wherein each field period, which is defined by a vertical synchronizing signal according to display data, has a vertical retrace period and each of the plurality of the partial regions is subjected to horizontal scanning in a 1/n horizontal scanning period obtained by dividing one horizontal scanning period, which is defined by a horizontal synchronizing signal according to display data, by the total number n, where n is a natural number of two or more, of the plurality of partial regions, and the scanning line driving circuit supplies the scanning signals such that a supply sequence of the scanning signals to one scanning line, which is disposed at an edge of one side along the scanning lines in the image display region, among the plurality of scanning lines becomes last for each field period.
