Abstract: A method of making a reflective tray that is useful in backlight modules for electronic devices comprises (a) providing a reflective tray template comprising a polymeric dielectric multilayer reflector on a compliant pad, the reflective tray template having a first major surface, an opposing major surface, and a reflective tray bottom area having corners; and (b) pressing a blade into the first major surface of the polymeric dielectric multilayer reflector along the perimeter of at least one side of the reflective tray bottom area to form a reflective tray side extending perpendicular to the reflective tray bottom area.

Abstract: The present disclosure relates to reflective trays (101) comprising a polymeric dielectric multilayer reflector material, backlight modules incorporating said reflective trays, articles using said backlight modules, and methods of making said reflective trays useful for backlight modules. In particular, the backlight modules have a reduced tendency to leak light into unwanted areas, and also form a compact unit having a narrow bezel, that at least partially surrounds the components of the backlight and/or the display.

Abstract: In a liquid crystal display (LCD), for example an LCD monitor or an LCD-TV, a number of light management films, including a diffuser layer, lie between the light source and the LCD panel to provide bright, uniform illumination. In some embodiments, the diffuser layer is attached to the lower side of the LCD panel. Some, or all, of the light management layers may be attached together as a laminated stack of films. In some embodiments, the diffuser layer is formed with a recessed region on one side and another optical film positioned within the recessed region.

Abstract: In a directly-illuminated liquid crystal display (LCD), for example an LCD monitor or an LCD-TV, a number of light management films, including a diffuser layer, lie between the light source and the LCD panel to provide bright, uniform illumination. The diffuser layer is attached to a substrate which is separate from the light source and the LCD panel, or may be attached to either the LCD panel or, when using a two dimensional light source, to the light source. The other light management layers may also be attached to the separate substrate or to the LCD panel or two-dimensional light source. High levels of illumination uniformity at the LCD may be achieved with a uniform (non-patterned) diffuser, even with relatively low levels of diffusion, when the diffuser is used with a brightness enhancing layer.

Abstract: A backlight subsystem includes first and second lightguides separated by an interfacial layer. The first lightguide has an output surface oriented toward an associated first illumination field, a back surface, and at least one light input edge. The second lightguide has output surface oriented toward an associated second illumination field, a back surface, and at least one light input edge. An interfacial layer is arranged between the back surfaces of the first lightguide and the second lightguide. The interfacial layer is substantially optically non-absorbing and may be predominately optically transmissive or predominately optically reflective.

Abstract: In a directly-illuminated liquid crystal display (LCD), for example an LCD monitor or an LCD-TV, a number of light management layers lie between the light source and the LCD panel to provide bright, uniform illumination. The light management layers, including, for example, a diffuser, a reflective polarizer and a brightness enhancing layer, are contained in a light management unit that is formed from two subassemblies. The two subassemblies each contain a substrate and are attached together so as to leave a gap between the two subassemblies. The diffuser is located in one of the subassemblies, and the other light management layers may be in either of the subassemblies, or may be disposed in the gap between the subassemblies.

Abstract: A light guide includes an extractor layer and a substrate layer. Each layer has a first major surface and a second major surface. The second major surface of the extractor layer is in contact with the first major surface of the substrate layer, and the first major surface of the extractor layer has a plurality of discrete light extractors capable of extracting light propagating in the light guide such that light is extracted in a predetermined pattern over the first major surface of the extractor layer. In some embodiments, at least one of the extractor layer or substrate layer is flexible.

Abstract: A coated optical fiber, preferably a GGP optical fiber includes an optical fiber core, and a silica cladding over the optical fiber core, to provide a silica clad core. A permanent polymeric coating forms on the silica cladding during ultraviolet radiation of a photocurable composition containing a non-hydrolyzable photoinitiator. The coated optical fiber has a diameter from about 120 microns to about 160 microns and a relative frequency distribution of at least about 85% for dynamic fatigue measurements between about 49.2×103 kg/cm2 (700 kpsi) and about 63.3×103 kg/cm2 (900 kpsi).

The protective coating has a Shore D hardnees value of 65 or more and remains on the optical fiber during connectorization so that the fiber is neither damaged by the blades of a stripping tool nor subjected to chemical or physical attack.
