Patent ID: 7262758

Claim:
A display apparatus for producing colored pixelated light, comprising: a) a backlight unit for providing a pump-beam light; b) a microcavity light-producing array responsive to pump-beam light and having pixels wherein each pixel includes: i) a transparent substrate; ii) a bottom dielectric stack reflective to light over a predetermined range of wavelengths; iii) an active region responsive to pump-beam light for producing display light; and iv) a top dielectric stack spaced from the bottom dielectric stack and reflective to light over a predetermined range of wavelengths; c) a light shutter for permitting selected display light from the microcavity light-producing array to pass therethrough; d) a polarizing layer disposed between the microcavity light-producing array and the light shutter; and e) a beam expander disposed over the light shutter for increasing the angular cone of view of the display light.
