Patent ID: 8659518

Claim:
A method of driving a pixel circuit, the pixel circuit comprising a light emitting device having a first electrode and a second electrode; a driving transistor having a gate terminal, a first terminal and a second terminal, the first terminal of the driving transistor being connected to the first electrode of the light emitting device; a first capacitor having first and second terminals, the first terminal of the first capacitor being connected to the gate terminal of the driving transistor, the second terminal of the first capacitor being connected to the first terminal of the driving transistor and the first electrode of the light emitting device; a first switch transistor having a gate terminal, a first terminal and a second terminal, the first terminal of the first switch transistor being connected the gate terminal of the driving transistor and the first terminal of the first capacitor; and a programming circuit having a programming transistor, the programming transistor being connected to the first electrode of the light emitting device and having a gate terminal directly connected to a data line; the method comprising the steps of: at a programming cycle of the pixel circuit, turning the programming transistor on; after the programming cycle, turning the programming transistor off for the remainder of a frame time comprising the programming cycle followed by a driving cycle during the frame time.
