A display includes a first housing portion having graphic openings and a second housing portion spaced apart from the first housing portion. A first circuit board has LEDs and is disposed between the first and second housing portions. A first side wall and a second side wall define photon recycling cavities in a sequence wherein adjacent photon recycling cavities have a shared end wall an LED. The first side wall has a first angular surface and the second side wall has a second angular surface. The first angular surface and the second angular surface redirecting light from an associated LED of the plurality of LEDs so that light from the plurality of light emitting diode is indirectly communicated through the graphic openings after reflecting from the first angular surface and the second angular surface.
A display comprising:
The display of 1 wherein the shared end wall comprises angled surfaces so that light from the plurality of light emitting diodes is indirectly communicated through the graphic openings after reflecting from angled surfaces of the end walls.
A display comprising:
