Abstract:
1. A driving method for driving an electro-optical device in which a plurality of subpixels are arranged corresponding to intersections of a plurality of scanning lines and a plurality of data lines, the method comprising: a first mode, and a second mode, supplying a first scanning signal to first subpixels among the plurality of subpixels at a time in the first mode, the first scanning signal controlling a switch included in each of the first subpixels to turn each of the first subpixels on or off in response to gray scale data indicating the gray scale of a pixel, supplying a second scanning signal to second subpixels among the plurality of subpixels at a time in the second mode, the second scanning signal controlling a switch included in each of the second subpixels to supply a substantially identical voltage to each of the second subpixels in response to gray scale data indicating the gray scale of the pixel, the number of the first subpixels being different from the number of the second subpixels, turning a first switch of a subpixel on or off in response to a signal supplied to a corresponding scanning line, storing in a storage element of the subpixel the storage content corresponding to the signal level at a corresponding data line when the first switch is turned on, selecting with a second switch of the subpixel between a first signal line and a second signal line in response to the storage content of the storage element in the first mode, while sampling, in the second mode, the voltage applied to the first signal line at the timing of the gray scale data of the one pixel of the subpixels during the on period of the first switch, and receiving at a subpixel electrode the voltage selected or sampled by the second switch.
