Claim One:
1. 3D (three-dimensional) stereoscopic image rendering system comprising: an image projecting layer disposed in an X-Y plane, said image projecting layer comprising a black matrix-framed geometrical array of subpixels capable of emitting light; a lenticular lens sheet formed over said image projecting layer, wherein said lenticular lens sheet comprises a multiplicity of parallel, contiguous and substantially identically shaped lenticular lenses having bases that are flat and co-planar, wherein said lenticular lenses are capable of projecting images generated by light emitted from said subpixels into left and right directions to create a visually perceivable 3D stereoscopic image at an optical vertical distance, OVD, above said lens sheet; wherein each said lenticular lens is formed of a lens material having an index of refraction n L and wherein each said lenticular lens is shaped as a uniform semi-cylinder of length G having a flat base and convex cap, whose longitudinal axis extends for said length G along a Y-direction and, in a transverse X-Z plane, has a convex cross-section of diameter F, or wherein each said lenticular lens is shaped as a similarly aligned segmented semi-cylinder of flat base, each of whose segments may differ in shape or optical properties and may be separated from an adjacent segment by a spacer layer; and a carrier layer of thickness C formed on said co-planar flat base of said lenticular lens sheet; and wherein a multi-layered structure is, formed on said carrier layer and interposed between said carrier layer and said image projecting layer, wherein said multilayered structure includes either a multi-component adhesive layer of thickness T comprising a matrix of adhesive material having an index of refraction n A capable of fastening said multilayered structure to said image projecting layer; or wherein said multi-layered structure includes a plate formed of a light diffusing material that contacts said image projecting layer but is not fastened to it; whereby, as a result of a choice of the values of n L and n A , when subpixels of said image projecting layer are emitting light, the intensity of multiple, diffuse, internally-reflected light rays in said lenticular lenses, propagating along the lengthwise Y direction within each of said lenticular lenses or in the transverse X direction between said lenticular lenses, is eliminated or reduced; and as a result of said elimination or reduction in intensity, there is a corresponding elimination or reduction in variations in intensity of leakage radiation produced at regions of varying reflectivity longitudinally distributed along said lenticular lens base together with the moiré patterns that are produced by said variations in intensity; and as a result of said reduction or elimination of said diffuse internally-reflected light propagating transversely between said lenticular lens elements, leakage of said transversely propagating light that is perceived as crosstalk between left and right projected images is reduced or eliminated.
