Patent ID: 7439967

Claim:
A driving circuit of an electro-optical device for driving pixels provided at intersections of a plurality of scanning lines and a plurality of data lines, the driving circuit comprising: a scanning line driving circuit sequentially selecting the plurality of scanning lines and applying a selected voltage to the selected scanning lines; and a data line driving circuit performing, on the plurality of data lines, one of: leading-edge driving including: applying a turning-on voltage having a polarity reverse to a polarity of the selected voltage in a period from a starting point of a period when the selected voltage is applied to the scanning lines to a point of time after a lapse of time corresponding to the gray scale of the pixels corresponding to the intersections of the data lines and the scanning lines, in a greater period when the selected voltage is applied to the scanning lines; and applying a turning-off voltage having the same polarity as the polarity of the selected voltage in the remainder of the greater period; and trailing-edge driving including: applying the turning-on voltage in a period from the point of time preceding the final point of the period when the selected voltage is applied by the length of time corresponding to the gray scale of the corresponding pixel; and applying the turning-off voltage in the remainder of the greater period, wherein the data line driving circuit drives the respective data lines that belong to a first group among the plurality of data lines by the one of the leading-edge driving and the trailing-edge driving in the period when the selected voltage is applied to the respective scanning lines, drives the respective data lines that belong to a second group different from the first group by a different driving mode than the one of the leading-edge driving and the trailing-edge driving used for the first group, and alternately changes the driving modes between the leading-edge driving and the trailing-edge driving for the respective data lines when the selected voltage is applied to the scanning line corresponding to one pixel.
