Patent ID: 7352348

Claim:
A driving circuit for an electro-optical device, including a display unit having pixels formed at intersections of a plurality of source lines and a plurality of scanning lines arranged to cross each other and an electro-optical material driven by turning on switching elements provided in the pixels by scanning signals supplied via the scanning lines and by supplying image signals supplied to the source lines to pixel electrodes of the respective pixels via the switching elements, the driving circuit comprising: a scanning driver, with respect to the display unit, to select n, where n is an integer of 2 or greater, scanning lines spaced apart from each other in one horizontal period of an input image corresponding to a number of pixels in the display unit to sequentially supply gate pulses to the selected n scanning lines and to shift the selected n scanning lines by one line in the next one horizontal period; an image rearranging unit to convert a blanking signal included in the input image into a blanking signal having a predetermined level, to synthesize an input image including the level-converted blanking signal with a delayed signal thereof, and to arrange the synthesized image having a horizontal frequency n times larger than a horizontal frequency of the input image in a signal arrangement according to scanning of the scanning driver, thereby obtaining a write image; and a data driver to receive an image signal of the write image from the image rearranging unit and to invert the polarity of the image signal for every horizontal write period, the horizontal write period being 1/n times smaller than the horizontal period of the input image, to supply the image signal to the plurality of source lines.
