Abstract
What is disclosed are methods of non-uniformity compensation for active matrix light emitting diode device (AMOLED) and other emissive displays. For each pixel, greyscale level offsets for a number of predetermined greyscale drive levels which produce a uniform flat field are determined and used to generate a correction function for the pixel.
