Abstract

A method and system for light emitting device displays is provided. The system includes one or more pixels, each having a light emitting device, a drive transistor for driving the light emitting device, and a switch transistor for selecting the pixel; and a circuit for monitoring and extracting the change of the pixel to calibrate programming data for the pixel. Programming data is calibrated using the monitoring result.
