摘要： Optical constructions are disclosed. A disclosed optical construction includes first and second major surfaces (110,120) that face each other and are separated by an air gap (130). The first and second surfaces are susceptible to physically contact each other at a first location (x) in the air gap. The optical construction further includes an optical film (140) that is disposed at the first location to prevent the first and second major surfaces from contacting each other at the first location. The optical film has an effective index of refraction that is not greater than about 1.3.

摘要： A multifunctional optical film for enhancing light extraction includes a flexible substrate, a structured layer, a high index backfill layer, and an optional passivation layer. The structured layer effectively uses microreplicated diffractive or scattering nanostructures located near enough to the light generation region to enable extraction of an evanescent wave from an organic light emitting diode (OLED) device. The backfill layer has a material having an index of refraction different from the index of refraction of the structured layer. The backfill layer also provides a planarizing layer over the structured layer in order to conform the light extraction film to a layer of an OLED display device. The film may have additional layers added to or incorporated within it to an emissive surface in order to effect additional functionalities beyond improvement of light extraction efficiency.

摘要： This application describes a front-lit reflective display assembly including a reflective display and an illumination article for front-lighting the display when the article is optically coupled to a light source. The illumination article includes a variable index light extraction layer optically coupled to a lightguide. The variable index light extraction layer has first and second regions, the first region comprising nanovoided polymeric material, the second region comprising the nanovoided polymeric material and an additional material, the first and second regions being 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. Front-lit reflective display devices including the front-lit reflective display assembly optically coupled to a light source are also described.
