Method of driving pixel circuit, light-emitting apparatus, and electronic apparatus
摘要:
There is provided a method of driving a pixel circuit. The method includes: 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.
