A display apparatus for producing colored pixelated light includes a
backlight unit for providing a pump-beam light. The apparatus also
includes a microcavity light-producing array responsive to pump-beam
light and having pixels wherein each pixel including a transparent
substrate, a bottom dielectric stack reflective to light over a
predetermined range of wavelengths, an active region responsive to
pump-beam light for producing display light, and a top dielectric stack
spaced from the bottom dielectric stack and reflective to light over a
predetermined range of wavelengths. The apparatus further includes a
light shutter for permitting selected display light from the microcavity
light-producing array to pass therethrough, a polarizing layer disposed
between the microcavity light-producing array and the light shutter, and
a beam expander disposed over the light shutter for increasing the
angular cone of view of the display light.
