摘要
A display device includes an array of LEDs, an array of LCD pixels, and a display controller. The display controller is configured to compensate for one or more sources of color variation in light produced by the LEDs. The display controller can determine a first color variation at a given LCD pixel based on the distance between the given LCD pixel and one or more LEDs. The display controller can also determine a second color variation at the given LCD pixel based on a current level supplied to the one or more LEDs. The display controller configures the given LCD pixel to filter light that is received from the one or more LEDs in a manner that reduces or eliminates either or both of the first and second color variations.
