Abstract
A system is disclosed for correcting a color of light being generated by an LCD image system having an LED and an LCD glass component that is illuminated by the LED. A plurality of color correction filters are constructed, with each providing a predetermined, differing color shift to light being output by the LCD glass component, based on a measured color of the light being output from the LCD glass component. Each of the color correction filters is constructed based on a known range of color variations that may be present in a color of the light being output from the LCD glass component. Each filter provides a color shift that shifts the color of the light being output from the LCD glass component from outside a predetermined target color area back into the predetermined target color area.
