Abstract
A method and system for driving a pixel circuit in an active matrix display is provided. The system implements a feedback driving scheme to enhance programming speed of the pixel circuit. The system includes a column driver for driving the pixel circuit with feedback. A controller controls a signal on a programming signal line during a programming cycle. For example, the driver may include a model for reducing the settling time of a pixel current. During the programming mode, an accelerating pulse may be provided to accelerate the programming of the pixel circuit.
