摘要： This application describes a back-lit transmissive display including a transmissive display (620) and a variable index light extraction layer (640) optically coupled to a lightguide (630). The variable index light extraction layer has first regions (140) of nanovoided polymeric material and second regions (130) of the nanovoided polymeric material and an additional material. The first and second regions are disposed such that for light being transported at a supercritical angle in the lightguide, the variable index light extraction layer selectively extracts the light in a predetermined way based on the geometric arrangement of the first and second regions. The transmissive display may be a transmissive display panel or a polymeric film such as a graphic.

摘要： Optical stack is disclosed. The optical stack includes a first optical stack that includes, a first optical adhesive layer, and a reflective polarizer layer that is disposed on the first optical adhesive layer.

Each unitary discrete structure defines a penetration depth and a penetration base at the interface between the penetrating and non-penetrating portions of the unitary discrete structure. The penetration base has a minimum penetration base dimension. The plurality of unitary discrete structures has an average penetration depth and an average minimum penetration base dimension. The ratio of the average penetration depth to the average minimum penetration base dimension is at least 1.5. The peel strength between the first and second optical stacks is greater than about 30 grams/inch.

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.
