Patent ID: 7348942

Claim:
An electro-optical device, comprising: a plurality of scanning lines; a plurality of data lines; a plurality of pixels corresponding to intersections of the scanning lines and the data lines, each of the pixels having a storage device to store data, a driving element to set a driving current flowing from a first power supply line to a second power supply line, and an electro-optical element to emit light with a brightness in accordance with the set driving current; a scanning line driving circuit to select the scanning line corresponding to a pixel in which data is to be written by outputting scanning signals to the scanning lines; a data line driving circuit to output data to the data line corresponding to the pixel in which data is to be written in cooperation with the scanning line driving circuit; and a power supply line control circuit to perform impulse driving of the electro-optical element more than once by setting the electric potential of at least one of the first power supply line and the second power supply line to be variable and alternately and repeatedly applying a forward bias and a reverse bias to the electro-optical element during a period of time from the moment in which the scanning line corresponding to the pixel in which the data is to be written is selected, to the moment in which the same scanning line is selected again.
