Abstract
An NVIS-compatible backlight assembly for an LCD display comprising a short-wavelength (blue) light source positioned in a first layer and a photoluminescent layer positioned adjacent the first layer for transforming blue monochrome emission from the blue light source into tri-color light for use as a full-color light source, while minimizing radiance in NVIS-sensitive regions.
