Electro-optical device, electronic apparatus, and method of driving electro-optical device with variable subfield driving for temperature compensation

An electro-optical device comprising:

• pixels that are disposed in correspondence with intersections of scanning lines and signal lines and are driven in response to an ON voltage or an OFF voltage supplied to the signal lines at a time when each of the scanning lines is selected;
• a scanning line driving circuit that sequentially selects the scanning lines in each of a plurality of subfields within a field;
• a signal line driving circuit that outputs the ON voltage to the signal lines at the time when each of the scanning lines is selected in at least one temperature compensation subfield among the plurality of subfields and outputs either the ON voltage or the OFF voltage to each of the signal lines in accordance with a designated gray scale of a pixel corresponding to the corresponding scanning line and the corresponding signal line at a time when each of the scanning lines selected in each of a plurality of gray scale control subfields, which is different from the temperature compensation subfield, out of the plurality of subfields;
• a temperature detecting unit that detects a temperature;
• and
• a control unit that sets a time length of the temperature compensation subfield to be changed in accordance with the temperature detected by the temperature detecting unit,
• wherein the scanning line driving circuit includes:
• a transmission circuit that generates a plurality of transmission signals in which transmission pulses acquired by sequentially shifting a start pulse are disposed;
• and
• a pulse generating circuit that generates a first selection pulse corresponding to a leading edge of each of the transmission pulses and a second selection pulse corresponding to a trailing edge of each of the transmission pulses and outputs the selection pulses to each of the scanning lines,
• wherein the first selection pulse directs to select each of the scanning lines in one of the temperature compensation subfield and the gray scale control subfield, and the second selection pulse directs to select each of the scanning lines in the other of the temperature compensation subfield and the gray scale control subfield, and
• wherein the control unit controls a pulse width of the start pulse in accordance with the temperature detected by the temperature detecting unit.
