Patent ID: 8310416

Claim:
A method of driving a pixel circuit including a light-emitting device, a driving transistor serially connected to the light-emitting device, and a storage capacitance interposed between a path between the light-emitting device and the driving transistor and a gate of the driving transistor, comprising: turning on the driving transistor by resetting a voltage across the storage capacitance in a resetting period; performing a compensating operation of asymptotically causing the voltage across the storage capacitance to converge with a voltage corresponding to a threshold voltage of the driving transistor by applying a first reference voltage to the gate of the driving transistor, over a time duration variably set according to a gradation value designated to the pixel circuit, in a compensating period after the elapse of the resetting period; changing the voltage across the storage capacitance from a voltage set by the compensating operation to a voltage corresponding to the gradation value by applying a gradation voltage corresponding to the gradation value from a signal line to the gate of the driving transistor, in a writing period after the elapse of the compensating period; and supplying a driving current corresponding to the voltage across the storage capacitance to the light-emitting device by stopping applying a voltage to the gate of the driving transistor, in a driving period after the elapse of the writing period, wherein in the compensating period, the compensating operation performed by applying the first reference voltage from the signal line to the gate of the driving transistor, and the compensating operation is stopped by changing the first reference voltage of the signal line into a second reference voltage to transition the driving transistor into an OFF state.
