Abstract
A multi-clad black display panel, and a method of making a multi-clad black display panel, are disclosed, wherein a plurality of waveguides, each of which includes a light-transmissive core placed between an opposing pair of transparent cladding layers and a black layer disposed between transparent cladding layers, are stacked together and sawed at an angle to produce a wedge-shaped optical panel having an inlet face and an outlet face.
Claims41
An optical display panel for displaying a projected image, said optical display panel comprising:
- a plurality of stacked planar optical waveguides, wherein each waveguide has a receiving end and an outlet end, which plurality of receiving ends form an inlet face and which plurality of outlet ends form an outlet face, wherein each waveguide receives image light at the inlet face, and outlets the image light at the outlet face, wherein each waveguide is formed of a core between an opposing pair of cladding layers, and wherein each of said cladding layers extends from the inlet face to the outlet face;
- and
- a black layer disposed between adjoining cladding layers, wherein each of said black layers extends from the inlet face to the outlet face.
