Abstract
A display includes a first housing portion having graphic openings therein, a second housing portion spaced apart from the first housing portion and a first circuit board having a plurality of light emitting diodes. The first circuit board is disposed between the first housing portion and the second housing. The first housing portion and the second housing portion form a first photon recycling cavity having the plurality of light emitting diodes disposed therein so that light from the plurality of light emitting diodes is indirectly communicated through the graphic opening after reflecting within the photon cavity.
