Abstract
A light emitting device display, its pixel circuit and its driving technique is provided. The pixel includes a light emitting device and a plurality of transistors. A bias current and programming voltage data are provided to the pixel circuit in accordance with a driving scheme so that the current through the driving transistor to the light emitting device is adjusted.
Claims5
A pixel circuit comprising:
- a light emitting device;
- a storage capacitor;
- a driving transistor for providing a pixel current to the light emitting device, the driving transistor having a gate terminal, a first terminal connected to the storage capacitor, and
- a second terminal connected to the light emitting device;
- a first switch transistor electrically connected between a bias line and the first terminal of the driving transistor;
- and
- a second switch transistor electrically connected between a reference voltage line and the gate terminal of the driving transistor;
- and
- an emission control transistor having a gate terminal connected to an emission control line, a first terminal connected to a voltage supply line different from the reference voltage line, and a second terminal connected to the first terminal of the driving transistor.
