摘要： A method for fabrication of a rear projection article forms an arrangement of refractive elements on one surface of a transparent support and forms an apertured surface on the opposite surface of the support. A photographic positive reversal emulsion is applied to the opposite surface of the substrate to form a light-sensitive layer. Visible light is directed, as exposure radiation, through the refractive elements, exposing the light sensitive layer to form an exposed layer. The exposed layer is developed photographically using a positive reversal process to form the apertured surface thereby.

摘要： A brightness enhancement article (30) provides light from a two-dimensional surface. The brightness enhancement article (30) has a plurality of light collecting structures (32), wherein each light collecting structure (32) is longitudinally extended in a length direction along the surface. Each light collecting structure (32) has an input aperture (33) optically coupled to a light-providing surface and an output aperture (35) distal from the input aperture (33), wherein the output aperture (35) has a surface area that is larger than the surface area of the input aperture (33). A pair of curved side walls (38) extend from the output aperture (35) toward the input aperture (33). In a cross section taken orthogonally with respect to the length direction, the curved side walls (38) approximate a parabolic curvature.
