Patent ID: 7474302

Claim:
A driving circuit of an electro-optical device, the electro-optical device, comprising: pixels formed corresponding to respective intersections between a plurality of data lines and a plurality of scanning lines to constitute a display unit; switching elements which are turned on by scanning signals supplied to the scanning lines and which are provided in the pixels; and pixel electrodes in the pixels to which image signals supplied to the data lines are applied through the switching elements when the switching elements are turned on, the driving circuit, comprising: a transmission clock generator that generates a transmission clock for sequentially transmitting the scanning signals to the scanning lines in synchronism with a signal having a frequency equal to a horizontal frequency of input image signals and outputting the transmission clock as a timing signal; a vertical reset signal generator that generates a vertical reset signal synchronized with the transmission clock generated in close proximity of a vertical synchronizing signal of the input image signals; a scanning start pulse generator that generates a scanning start pulse defining a start timing of a vertical scanning operation on the basis of the transmission clock and the vertical reset signal and outputting the scanning start pulse as a timing signal; and a writing image generator that generates writing image signals to be supplied to the data lines by delaying the input image signals on the basis of the transmission clock and the vertical reset signal.
