Abstract:
A driving method of an electro-optic device includes initializing a gate voltage of a driving transistor; and performing a data write operation where 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 is at a drain side of the driving transistor and the second transistor is between the first transistor and a gate side of the driving transistor. When the data write operation ends, the second transistor is first turned off and, subsequently, the first transistor is turned off. The second transistor is again turned on after the first transistor is turned off.
