Driving method for organic electroluminescence light emitting section
Abstract:
A driving method for an organic EL light emitting section is provided which achieves optimization of a mobility correction process for a transistor of a driving circuit in response to luminance. The light emitting section may include a driving circuit with a driving transistor, an image signal writing transistor and a capacitor section having a pair of electrodes (corresponding to a first node ND1 and a second node ND2). A variable correction voltage which relies upon an image signal voltage is applied to the first node ND1 and a voltage which is higher than a potential of the second node ND2 in a threshold voltage cancellation process is applied to the drain electrode of the driving transistor, between the threshold voltage cancellation process and a writing process, to raise the potential of the second node ND2 in response to a characteristic of the driving transistor.
