Abstract:
1. A method to drive an electro-optical device including, a plurality of scan lines, a plurality of data lines, a plurality of pixel circuits having a switching transistor, a holding element, a driving transistor, and an electro-optical element, the plurality of pixel circuits being provided at the intersections of the plurality of scan lines and the plurality of data lines, the method comprising: first transmitting a scan-signal to turn the switching transistor on to each of the plurality of pixel circuits via one of the plurality of scan lines—the one corresponding to the pixel circuit—and transmitting a data signal to the holding element via one of the plurality of data lines—the one corresponding to the pixel circuit, and the switching transistor—accumulating an electrical amount corresponding to the data signal in the holding element, and setting the driving transistor to a first conduction state according to the electrical amount corresponding to the data signal, the electrical amount being accumulated in the holding element; and second transmitting a driving voltage or a driving current with a voltage level or a current level corresponding to the first conduction state to the electro-optical element, a plurality of times, and after the first and second transmittings are performed, setting the driving transistor to a second conduction state being performed before the first transmitting is performed next time.
