    摘要： Optical constructions use a low index of refraction layer (120) disposed between a low absorption layer (101) and a high absorption layer (103) to increase confinement of light to the low absorption region of the optical constructions. Low index layers can be used in optical constructions that have multi-tiered light confinement. In these constructions, a first tier of reflection is provided when light is reflected at the surface of a low index optical film which is disposed directly or indirectly on a light guide (110). A second tier of reflection occurs at the surface of a light redirecting film having appropriately oriented refractive structures.

    摘要： Collimating light engines, methods of making collimating light engines, and articles incorporating collimating light engines are disclosed. In one aspect, a light source and circuitry can be disposed between a reflector and a reflective baffle to form a collimating light engine. The light source is at least partially obscured from view by the reflective baffle. Light emitted from the light source is partially collimated upon leaving the light engine. Light uniformity of the output surface of a backlight can be proved by disposing an array of the collimating light engines in the backlight

    摘要： Suspended optical film assemblies including a frame, an optical film, and an elastomeric film are disclosed. The elastomeric films include a first attachment region, a second attachment region, and a free region between the first and second attachment regions. The first attachment region is affixed to the frame; the second attachment region is affixed to the optical film, so that the free region is in tension and supports the optical film within the frame. The tension in the elastomeric film free region can help maintain flatness and reduce distortion in the optical film during environmental changes that influence dimensional changes in the frame, optical film, and elastomeric film.

    摘要： A stretcher for substantially uniaxially orienting a film includes a plurality of gripping members to hold opposing edge portions of the film, paths along which the gripping members travel to stretch the film in a stretching region, and a drive mechanism to convey the film and gripping members along a machine direction. At least a portion of the paths in the stretching region define diverging, curvilinear courses disposed in-plane. The paths are configured such that during the stretching an extent of uniaxial character, U, is between zero and unity and a minimum value of an extent of uniaxial character, U, is at least 0.70 over a final portion of the stretching after achieving a TDDR of 2.5. U is defined as U=(1/MDDR−1)/(TDDR1/2−1), wherein TDDR is greater than 4 at an end of the stretching region.

    摘要： An edge-lit backlight having a light recycling cavity with concave transflector is disclosed. The edge-lit backlight has an output area and includes a back reflector facing the output area of the backlight. The backlight further includes a transflector that partially transmits and partially reflects incident light, the transflector being shaped to form a concave structure facing the back reflector to provide one or more recycling cavities therebetween, where the one or more recycling cavities substantially fill the output area of the backlight. The backlight further includes at least one light source positioned adjacent a first edge of the backlight. The at least one light source is operable to inject light into the one or more recycling cavities through an input surface of the one or more recycling cavities, where the input surface is substantially orthogonal to the output area, and where the at least one concave structure converges with the back reflector in a direction distal from the input surface.
