ABSTRACT:
A driving method for an organic electroluminescence light emitting section using a driving circuit, the driving circuit includes a driving transistor, an image signal writing transistor, a light emission control transistor, and a capacitor section. The driving method includes the steps of: carrying out a preprocess of applying a first node initialization voltage and applying a second node initialization voltage; carrying out a threshold voltage cancellation process; placing the light emission control transistor into an on state, a writing process of applying an image signal; and placing the image signal writing transistor into an off state so that current is supplied to the organic electroluminescence light emitting section to drive the organic electroluminescence light emitting section.
