Summary: | A rear projection screen includes an array of pin-hole apertures to pass display light incident from a first side of the rear projection screen through to a viewing side of the rear projection screen opposite the first side. An array of concentrator structures surrounds the pin-hole apertures and defines concentrating optical pathways. The concentrating optical pathways each have an input aperture for collecting the display light and an output defined by a corresponding one of the pin-hole apertures to emit the display light. The input apertures are larger than the pin-hole apertures. |
