Abstract
A method and system for compensation for luminance degradation in electro-luminance devices is provided. The system includes a pixel circuit having a light emitting device, a storage capacitor, a plurality of transistors, and control signal lines to operate the pixel circuit. The storage capacitor is connected or disconnected to the transistor and a signal line(s) when programming and driving the pixel circuit.

1-30. (canceled)
A pixel circuit comprising:
- a light emitting device;
- a storage capacitor for charging to a voltage that is a function of a programming voltage and the voltage of said light emitting device during a programming cycle;
- and
- a driving transistor for supplying, via a source terminal, a driving current to the light emitting device during a driving cycle, the driving transistor having a gate terminal connected to a first terminal of the storage capacitor, the driving transistor having a threshold voltage less than said initial voltage.
