Abstract
Official abstract text for this publication.
A method and system for programming, calibrating and driving a light emitting device display is provided. The system may include extracting a time dependent parameter of a pixel for calibration.
First claim
Opening claim text (preview).
What is claimed is: 1. A method of controlling light emission from a pixel circuit including a light emitting device (LED), a drive transistor to provide a programmable drive current to the light emitting device, a programming input, and a storage device to store a programming value from said programming input, the method comprising: determining at least one time-dependent parameter of the pixel circuit, detecting a change in said determined time-dependent parameter, determini…
