发明名称 Electro-optical device and electronic apparatus
摘要 A driving circuit applies a voltage according to an assigned grayscale during each unit period of each display period, in such a manner that the applied voltage to a liquid crystal element during one of the unit periods and the applied voltage to the liquid crystal element during the other of the unit periods are opposite in polarity during each of the display periods, and an overdrive control unit enables the drive circuit to perform overdrive of a compensation grayscale according to a display image during the corresponding display period and to a display image during the immediately preceding display period during each of the first and second unit periods of each of the display periods, during each of the display periods.

主权项 1. An electro-optical device alternately displaying right-eye and left-eye images each of display periods, comprising: a plurality of pixels arranged corresponding to intersections between a plurality of scan lines and a plurality of signal lines; a drive circuit applying a voltage according to an assigned grayscale to each of the pixels during each of first and second unit periods of each of display periods in such a manner that the applied voltages to each of the pixels during the first and second unit periods of each of the display periods, respectively, are opposite in polarity, and the drive circuit sequentially selects each of the scan lines and applies the voltage according to the assigned grayscale to each of the pixels corresponding to the scan line in a selection state; and an overdrive control unit enabling the drive circuit to perform overdrive of a compensation grayscale according to a display image during a corresponding display period and to a display image during the immediately preceding display period during each of the first and second unit periods of each of the display periods, during each of the display periods, and the overdrive control unit controlling the overdrive on each of the pixels by the drive circuit in such a manner that, in a case where the assigned grayscale in the display image during one display period and the assigned grayscale in the display image during the display period immediately preceding the one display period are equal to each other, in the pixels corresponding to the first scan line, and the pixels corresponding to the second scan lines selected after the selection of the first scan line among the plurality of scan lines, an amount of overdrive compensation on the pixel corresponding to the second scan line exceeds the amount of overdrive compensation on the pixel corresponding to the first scan line, during one of the display periods.
