Abstract:
1. An optical panel system for displaying a projected light image, comprising: a plurality of planar optical waveguides in a stacked state, each waveguide having a first end thereby defining a plurality of first ends, and a second end thereby defining a plurality of second ends, wherein an inlet face is defined by the plurality of first ends; and a support system that aligns and supports the waveguides in the stacked state such that the waveguides are in a predetermined configuration; wherein the support system comprises at least two opposing edge structures having the waveguides positioned therebetween, and wherein the at least two opposing edge structures engage opposite edges of each waveguide to thereby provide the waveguides in the predetermined configuration; and wherein each waveguide is held in position relative to an adjacent waveguide using the support system while the waveguides are in the predetermined configuration, wherein at least one of the at least two opposing edge structures contains a mating surface, wherein at least one of the opposite edges of each waveguide contains a mating surface which is complementary to the mating surface of the at least one opposing edge structure, wherein each mating surface of the at least one opposing edge structure engages a corresponding complementary mating surface of the at least one of the opposite edges of each waveguide to thereby provide the waveguides in the predetermined configuration, and wherein at least one mating surface of the at least one opposing edge structure is substantially dovetail-shaped.
