Abstract:
1. A driving method of an electro-optic device comprising: initializing a gate voltage of a driving transistor; performing a data write operation where, when a data signal having a voltage level corresponding to a gradation is provided to the driving transistor, a threshold voltage of the driving transistor is compensated by turning on a first transistor and a second transistor connected in series between a drain and a gate of the driving transistor and a voltage is provided to a capacity element connected to the gate of the driving transistor to hold a voltage of the compensated data signal as a gate voltage, the first transistor being placed at a drain side of the driving transistor and the second transistor being placed at a gate side of the driving transistor; and performing a light-emitting operation by providing a drain current according to the held gate voltage of the driving transistor to a light-emitting element connected to the drain of the driving transistor, wherein, when the data write operation is ended, the second transistor of the first and second transistors being at a turn-on state is first turned off and, then, the first transistor is turned off; and wherein the second transistor is again turned on after the first transistor is turned off.
