Abstract
A display device may include a display having a pixels and a processor. The processor may receive image data, determine a digital offset value for a pixel based on a location of the pixel, such that the digital offset value compensates for one or more non-uniformity properties of the pixel. The processor may determine a scale factor associated with the pixel based on at least two of a luminance setting for the display, a driving mode of the display, and a gray level value for the pixel. The processor may then generate correction image data by applying the scale factor to the digital offset value, generate compensated image data based on the correction image data and the image data, and provide the compensated image data to the display.
