Abstract: Optical constructions use a low index of refraction layer disposed between a low absorption layer and a high absorption layer 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. A second tier of reflection occurs at the surface of a light redirecting film having appropriately oriented refractive structures.

Abstract: 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.

Abstract: A system for laminating an adhesive to a component includes a liner including a first major surface facing the component and a second major surface opposite to the first major surface. An adhesive is disposed on the first major surface. The adhesive is configured to be laminated to the component. A support pad engages the second major surface of the liner for laminating the adhesive to the component. Each of the support pad and the liner undergoes deformation upon engagement of the support pad with the liner. The support pad includes a body made of an elastic pad material and includes an upper surface facing the component, a lower surface opposite to the upper surface, and a lateral surface disposed between the upper surface and the lower surface. The liner includes a conformable liner material having a liner elastic modulus from about 5 megapascals (MPa) to about 650 MPa.
