A light emissive display having a specular waveguide that propagates short
wavelength light and photoluminescent features adjacent to the waveguide
that fluoresce, for example, in visible red, green, blue, and mixed
colors when selectively coupled with the short wavelength light. The
photoluminescent layers emit light primarily and, therefore, efficiently
in the direction of an observer only. This light emissive display may be
utilized as a planar light source, as patterned information signage, or
as a re-configurable information display containing intensity modulated
pixels. The light emissive display may be enhanced optically such that
only a small portion of ambient light is reflected from the display while
preserving the majority of emitted display luminance.
