Abstract
In one unit period of a display period, each pair of two scanning lines is selected and a gray scale potential corresponding to an image signal of pixels of one scanning line of each pair of scanning lines is supplied to each signal line. In another unit period, the other scanning line of each pair of scanning lines is selected and a gray scale potential corresponding to an image signal of the pixels of the other scanning line is supplied to each signal line.
Claims7
An electro-optic device alternately displaying right-eye and left-eye images, comprising:
- scanning lines;
- signal lines that intersect the scanning lines;
- pixels that are arranged to correspond to the intersections between the scanning lines and the signal lines and includes switching elements respectively, the switching elements turning on in response to the scanning signal which is supplied from the scanning lines;
- a scanning line driving circuit that simultaneously selects the scanning lines in accordance with each first combination formed by two scanning lines adjacent to each other in a first unit period, selects only one of the scanning lines of each first combination in a second unit period, simultaneously selects the scanning lines in accordance with each second combination formed by two scanning lines and shifted by one scanning line from the first combination in a third unit period, and simultaneously selects the scanning lines of each first combination in a fourth unit period, the first, second, third, and fourth unit periods being included in a display period in which the right-eye image and the left-eye image are displayed;
- and
- a signal line driving circuit that supplies the signal lines with a gray scale potential corresponding to an image signal of the pixels of the other scanning line of the first combination in the first unit period, supplies the signal lines with a gray scale potential corresponding to an image signal of the pixels of the one scanning line of each first combination in the second unit period, supplies the signal lines with a gray scale potential corresponding to an image signal of the pixels of the one scanning line of each second combination in the third unit period, and supplies the signal lines with the gray scale potential corresponding to the image signal of the pixels of the other scanning line of each first combination in the fourth unit period.
