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.

A night vision imaging system (NVIS)-compatible backlight assembly for an LCD display, comprising:
- a short-wavelength light source positioned in a first layer;
- and
- a photoluminescent layer positioned adjacent the first layer for transforming blue monochrome emission from the short wavelength light source into tri-color light for use as a full-color light source, while minimizing radiance in a NVIS range.
A night vision imaging system (NVIS)-compatible backlight assembly for an LCD display comprising a short-wavelength (blue) LED 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 an full-color light source, while minimizing radiance in NVIS-sensitive regions.
A night vision imaging system (NVIS)-compatible backlight assembly comprising a higher or equivalent energy/lower wavelength source positioned in a first layer and a photoluminescent layer positioned adjacent the first to create emissions that achieve full-color and monochrome NVIS compatibility.
