Patent ID: 8144081

Claim:
An electronic device comprising: a signal line; a unit circuit coupled to the signal line; a voltage supply line; and a voltage control circuit that sets a voltage of the voltage supply lines at any of a plurality of voltage values, the unit circuit having: a driving transistor that has a control terminal, a first terminal, and a second terminal coupled to the voltage supply line, a conductive state between the first terminal and the second terminal being set according to a voltage of the control terminal, a driven element, a first switching element that controls an electrical connection between the control terminal of the driving transistor and one of the first terminal and the second terminal, a capacitor element that has a dielectric provided between a first electrode and a second electrode, the first electrode being coupled to the control terminal of the driving transistor, the second electrode being directly connected to the signal line, a level of at least one of a driving current and a driving voltage that are supplied to the driven element being set according to the conductive state between the first terminal and the second terminal, the control terminal of the driving transistor and one of the first terminal and the second terminal being electrically connected to each other through the first switching element in a first period, a data signal being supplied to the second electrode through the signal line in the first period, a control signal that temporally varies in a second period being supplied to the second electrode in the second period, the voltage control circuit setting the voltage of the voltage supply line to a first voltage having a potential lower than the first terminal in at least a portion of the first period, and the voltage control circuit setting the voltage of the voltage supply line to a second voltage having a potential higher than the first terminal in at least a portion of the second period.
