Abstract
A scanning line driving circuit sequentially selects each of a plurality of scanning lines for each unit period. A signal supply circuit supplies, to a signal line, a gradation potential in accordance with a designated gradation of a pixel in a write period within the unit period. The signal supply circuit supplies a pre-charge potential to the signal line in a pre-charge period before the start of the write period in a first unit period of the plurality of unit periods, and the supply of the pre-charge potential to the signal line stops in a second unit period.
Claims9
An electrooptical device, comprising:
- a plurality of pixels that is arranged so as to correspond to each intersection of a plurality of scanning lines and a plurality of signal lines, and displays a gradation corresponding to a potential of the signal line at the time of selection of the scanning line;
- a scanning line driving circuit that sequentially selects the plurality of scanning lines for each of a plurality of unit periods;
- and
- a signal supply circuit that supplies, to each of the plurality of signal lines, a gradation potential corresponding to a designated gradation of each of the plurality of pixels in a write period of the unit period, supplies a pre-charge potential to each of the plurality of signal lines before the start of the write period in a first unit period of the plurality of unit periods, and stops the supply of the pre-charge potential corresponding to each of the plurality of signal lines in a second unit period which is different from the first unit period.
