Patent ID: 7969389

Claim:
An electronic device comprising: a plurality of scanning lines; a plurality of data lines; a plurality of electronic circuits disposed at intersections of the plurality of scanning lines and the plurality of data lines, each of the plurality of electronic circuits including a light emission element, a driving transistor that controls a driving current level of a driving current that is supplied to the light emission element, and a capacitor coupled to a gate of the driving transistor, the driving current level of the driving current passing through the driving transistor and the light emission element being determined by a charge stored in the capacitor; a current generating circuit that generates a current signal supplied to the plurality of electronic circuits; a voltage generating circuit that generates a voltage signal, the voltage signal being not supplied to the current generating circuit but supplied to the plurality of data lines; and the plurality of data lines being precharged by the voltage signal having a plurality of voltage signal levels, each of the plurality of voltage signal levels corresponding to a light emission level of the light emission element.
