Abstract:
1. An electro-optical device, comprising: a plurality of scan lines; a plurality of data lines provided so as to cross the plurality of scan lines; a unit circuit that is provided so as to correspond to each of the intersections of the plurality of scan lines and the plurality of data lines and that transmits a drive current according to a data voltage transmitted via a respective data line of the plurality of data lines to an electro-optical element; and a control device that generates and outputs either a two-level-data voltage for applying digital-gray-scale modulation to the electro-optical element or a multilevel-data voltage for applying analog-gray-scale modulation to the electro-optical element, based on image data, the control device including: the control device generating the two-level-data voltage for applying the digital-gray-scale modulation to the electro-optical element in low-electrical-power-consumption mode and the multilevel-data voltage for applying the analog-gray-scale modulation to the electro-optical element in non-low-electrical-power-consumption mode that drives the electro-optical element.
