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： 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： Direct-lit backlights and associated methods and components are disclosed in which a transflector that partially transmits and partially reflects incident light is shaped to form at least one concave structure facing a back reflector of the backlight. This provides at least one recycling cavity therebetween, the at least one recycling cavity substantially filling the output area of the backlight. At least one light source is disposed behind the output area to inject light into each cavity, and can be positioned in the recycling cavity or behind an aperture in the back reflector. The cavities are preferably shallow and wide, having a width-to-depth ratio of at least 5 or 10, and can provide uniform brightness and color at the output area with sparsely distributed light sources and in a thin profile backlight.
