摘要： In an embodiment of the present invention, a signal driver employs a two-stage system in which the potential of a signal line (SL) is switched from a reference potential (Vofs) to an intermediate potential (Vofs2), and then switched to a signal potential (Vsig) of a video signal. A scanner supplies a first control pulse to a scan line (WS) when the signal line (SL) is at the intermediate potential (Vofs2), and then supplies a second control pulse to thereby turn on and off a sampling transistor T1 when the signal line (SL) is at the signal potential (Vsig). Based on this configuration, two times of mobility correction (μ correction) are carried out.

摘要： 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.
