US Patent 11195483 Global light compensation in a variety of displays

A non-uniform illumination pattern is determined with a display panel of a display device. The non-uniform illumination pattern comprises different values of the one or more illumination properties in first and second spatial regions of the display panel. An illumination compensation pattern is generated based at least in part on the non-uniform illumination pattern. The illumination compensation pattern is configured to homogenize values of the illumination properties in a plurality of spatial regions of the display panel that include the first and second spatial regions, and implemented in the display device.
