Abstract
A method is provided for controlling display of an image on a display panel of a display device, the method comprising determining a commanded brightness level for the display panel, generating an index look-up table (LUT) and a mura LUT based on the brightness level and a relationship between pixel output and pixel value for each pixel of the display panel for each of a plurality of brightness levels, the relationship determined during a calibration phase and stored in memory of the display device, determining an index value for each pixel of the display panel based on the index LUT, determining a corrected pixel value for each pixel based on the mura LUT and the index value, and sending the corrected pixel value to that pixel within the display device.
