Pixel circuit driving method, light emitting device, and electronic apparatus including a variable driving signal
Abstract:
Provided is a method of driving a pixel circuit including a light emitting element and a driving transistor which are connected in series, and a storage capacitor disposed between the path between the light emitting element and the driving transistor and the gate of the driving transistor, the method including the steps of: supplying a driving signal, of which the time rate of change of the potential varies over time, to a gate of the driving transistor; stopping the supply of the driving signal at a point in time which is set to be variable in accordance with a gradation specified for the pixel circuit; and supplying a driving current corresponding to an open circuit voltage of the storage capacitor to the light emitting element.
