An optical panel system including stackable waveguides is provided. The
optical panel system displays a projected light image and comprises a
plurality of planar optical waveguides in a stacked state. The optical
panel system further comprises a support system that aligns and supports
the waveguides in the stacked state. In one embodiment, the support
system comprises at least one rod, wherein each waveguide contains at
least one hole, and wherein each rod is positioned through a
corresponding hole in each waveguide. In another embodiment, the support
system comprises at least two opposing edge structures having the
waveguides positioned therebetween, wherein each opposing edge structure
contains a mating surface, wherein opposite edges of each waveguide
contain mating surfaces which are complementary to the mating surfaces of
the opposing edge structures, and wherein each mating surface of the
opposing edge structures engages a corresponding complementary mating
surface of the opposite edges of each waveguide.
