Abstract
A display device includes an array of LEDs, an array of LCD pixels, and a display controller that compensates for one or more sources of color variation in light produced by the LEDs having multiple color components that change differently as a function of distance. The display controller can determine a variation of a received color value from a color of light emitted by a given LED at a given LCD pixel based on the distance between the given LCD pixel and the given LED, and determine an accumulated color value that includes the variation and multiple other corresponding variations of other received color values of light emitted by multiple other emitters determined based on respective distances from the given LCD pixel. The display controller configures the given LCD pixel to filter light that is received from the LEDs in a manner that reduces or eliminates the color variation.
