Driving method for organic electroluminescence light emitting section

Abstract

A driving method for an organic EL light emitting section achieves optimization of mobility correction for a transistor of a driving circuit in response to luminance. In a driving circuit formed from a driving transistor, an image signal writing transistor and a capacitor section having a pair of electrodes, a driving method carries out a pre-process, a threshold voltage cancellation process and a writing process. A variable correction voltage which relies upon the image signal voltage is applied to a first node of the capacitor and a voltage which is higher than a potential of the second node of the capacitor in the threshold voltage cancellation process is applied to the drain electrode of the driving transistor, between the threshold voltage cancellation process and the writing process, to raise the potential of the second node in response to a characteristic of the driving transistor.
