Abstract: A display apparatus includes a transparent substrate having first and second sides, an array of LED micro-display panels, and an array of collimating reflectors. The LED micro-display panels are disposed within the transparent substrate between the first and second sides and oriented to emit sub-image portions of a display image towards the first side. The collimating reflectors are disposed within the transparent substrate between the first side and the array of LED micro-display panels. The collimating reflectors are aligned with the LED micro-display panels to reflect the sub-image portions back out the second side of the transparent substrate. The LED micro-display panels are offset from the collimating reflectors to expand the sub-image portions prior to reflection by the collimating reflectors.

Abstract: An apparatus includes a holographic film having one or more reflective holograms recorded therein. One or more light sources positioned to direct light toward a corresponding one of the one or more holograms, and a dynamic mask positioned between the one or more light sources and the holographic film to spatially modulate light traveling between the one or more light sources and the one or more reflective holograms but not spatially modulate ambient light traveling through the hologram.
