Claim:
A night vision imaging system (NVIS) compatible display comprising: an array of light-emitting diodes (LEDs) of different colors configured to backlight the display; including an orange LED, a green LED, and a blue LED; the array including a means for blending the light from the different colors of LED so as to provide the perception of a single color output from the array; a controller configured to operate in a first operational mode to jointly illuminate multiple colors of LEDs including the orange LED at a first illumination intensity, the green LED at a second illumination intensity, and the blue LED at a third illumination intensity so as to provide light output from the array having a color perceived substantially as a continuous white spectrum; a liquid crystal display (LCD) providing a color display when illuminated by white light, the LCD positioned in front of the array to receive the light in there from; and wherein the first, second and third illumination intensities of the array when operated by the controller in the first operational mode do not exceed a maximum level designated for a NVIS standard compliant system and provide for a substantially white spectrum permitting the LCD to produce the color display.
