Abstract: Solar light redirecting glazing units include light redirecting and light diffusing constructions. The solar light redirecting glazing units may include a glazing substrate, a visible light diffusing layer, and a light redirecting layer oriented such that incoming solar light contacts the visible light diffusing layer before contacting the light redirecting layer. The solar light redirecting glazing units may include a glazing substrate, a patterned visible light diffusing layer, and a light redirecting layer. The solar light redirecting glazing units may include two glazing substrates separated by an intervening space with a solar light redirecting layer disposed on one glazing substrate, and a visible light diffusing layer disposed on the other glazing substrate.

Abstract: The present disclosure provides lamination transfer films and use of the lamination transfer films, particular in the fabrication of architectural glass elements, such as those used in Insulated Glass Units (IGUs). The lamination transfer films may be used to transfer functional layers and structures. The lamination transfer films may include a support film that can be removed during the transfer process, and the transferred materials are primarily inorganic. The resulting transferred structures on glass generally have high photo- and thermal-stability, and therefore can successfully be applied to the glass surfaces that are interior to the cavity within an IGU. The lamination transfer films can also be patterned such that macroscopic patterns of microoptical elements can be applied on a glass surface.

Abstract: Light management film constructions contain a first optical film having a first major surface and a second major surface opposite the first major surface. The first major surface is a microstructured surface with asymmetrical structures. The asymmetrical structures form an ordered arrangement of a plurality of multi-sided refractive prisms, with the multi-sided refractive prisms having a cross section of 3 or greater sides. A second optical film contacts and is bonded to substantially all of the structures of the first major structured surface of the first optical film. The light management constructions can be incorporated into optical articles such as windows.

Abstract: Dual-sided daylight redirecting films include an optical substrate with two solar light redirecting layers disposed on the major surfaces of the optical substrate. The light redirecting layers are microstructured surfaces forming a plurality of prism structures. At least one of the microstructured surfaces is an ordered arrangement of a plurality of asymmetric refractive prisms, and the two solar light redirecting layers are not identical or mirror images. Articles may be prepared that include the dual-sided daylight redirecting film and one or more glazing substrates.

Abstract: A virtual image (VI) device displays an image that appears to lie above or below the plane of the device. A method of manufacturing a VI display device includes calculating an initial VI flux pattern based on an object and then fabricating a substrate having a VI array pattern based on the initial VI flux pattern. A plurality of lenses may then be applied over the VI array pattern. The VI substrate may be static or dynamic, and may show grey scale information. A photomask may be used as an intermediate element in the manufacture of the VI substrate, or may act as the VI substrate itself. A method of producing the initial VI flux pattern includes virtually tracing rays generated by different points of the object to an image plane and ii) summing the rays from the different points. The rays may be traced through a lens array.

Abstract: Integral imaging 3D films for use with a display panel. The films include a flexible transmissive substrate having a first surface on a viewer side and a second surface for placement on the display panel. Convex lenses are located on the first surface. The second surface is planar for a plano-convex design or has concave lenses registered with the convex lenses for a convex-concave compound lens design. In the plano-convex design, the lens focus is in front of or behind the pixels. In the convex-concave design, the convex and concave lenses combined focus is in front of, at, or behind the pixels. In use the 3D films produce 3D images with motion parallax.

Other solar light redirecting glazing constructions include two glazing substrates, each glazing substrate having a light redirecting layer present on one of the major surfaces of the glazing substrate. The light redirecting layers are microstructured surfaces forming a plurality of prism structures. At least one of the microstructured surfaces is an ordered arrangement of a plurality of asymmetric refractive prisms, and the two solar light redirecting layers are not identical or mirror images.

Abstract: A virtual image display device has a lens array and a virtual image substrate disposed behind the lens array. The virtual image substrate is provided with a virtual image pattern registered to lenses of the lens array. In some embodiments the virtual image pattern can include grey scale information, where the grey scale information includes information in at least one of color and shape. In a static virtual image substrate, the virtual image information can include pixels of at least two different colors. An optical mask can have a virtual image pattern arranged so that a virtual image of an object appears to a viewer when a lens array is applied to the mask. In other embodiments, an optical mask can include an intermediate virtual image pattern containing information for manufacturing a virtual image substrate.
