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.

Display panel compensation methods

Systems and methods for correcting non-uniformity and for compensating for display OLED degradation utilize a correction factors k for each pixel, which is modelled and tracked based on grey level and a pixel parameter, such as temperature and time. The correction factor k is used to correct image data provided to an OLED display. To improve display uniformity for active matrix organic light emitting diode devices (AMOLED) and other emissive displays the panel luminance is a based on operating temperature, whereby the aging effect on a compensation parameter is independent of temperature.
