Abstract
Active matrix light emitting device display and its driving technique is provided. The pixel includes a light emitting device and a plurality of transistors. A capacitor may be used to store a voltage applied to a driving transistor so that a current through the light emitting device is independent of any shifts of the transistor and light emitting device characteristics. A bias data and a programming data are provided to the pixel circuit in accordance with a driving scheme.
Claims31
A display system comprising:
- a pixel circuit having a light emitting device and a plurality of transistors, the plurality of transistors including a driving transistor for providing a pixel current to the light emitting device;
- a driver for programming and driving the pixel circuit, the driver providing a controllable bias signal to the pixel circuit to accelerate the programming of the pixel circuit and to compensate for a time dependent parameter of the pixel circuit;
- and
- a controller for controlling the driver to generate a stable pixel current.
