    摘要： A film construction (320) includes a broad band reflective polarizing film (312) that may be immersed in an ultra low refractive index medium (322, 324). The reflecting polarizing film is characterized by a pass axis and a block axis, and its reflectivity for white light of the pass state polarization increases with increasing incidence angle to provide a compressed or narrowed viewing cone in one or two planes.

    摘要： An optical stack (400) having a plurality of alternating polymeric layers (401, 402) is described. The alternating layers may be alternating birefringent (syndiotactic polystyrene, sPS) and isotropic (CoPENa) layers, or alternating positively and negatively birefringent layers. Birefringent layers are made using polymers which form optically symmetrical crystallites upon stretching of the polymer. The optical stack has a large refractive index difference in the x-direction (the stretching direction) and small refractive index differences in the y- and z-directions (the non-stretching directions). The optical stack can be made using standard film tentering methods and may be a multilayer reflective polarizer.

    摘要： A film construction (610) includes a group of microlayers that reflect normally incident light polarized along a first axis more than normally incident light polarized along a second axis. The microlayers are arranged into optical repeat units (ORUs) that have a layer thickness distribution along a thickness axis perpendicular to the first and second axes that provides the group of microlayers with an intermediate reflectivity over an extended reflection band for a given incidence condition. The ORUs include thinner ORUs whose thicknesses are less than an average thickness, and thicker ORUs whose thicknesses are greater than the average thickness. The group of microlayers is optically immersed in a medium having a refractive index greater than air, such that “supercritical light” can propagate through the microlayers. The microlayers are oriented such that, on average, the thinner ORUs are closer than the thicker ORUs to an output surface of the construction. By “supercritical light” is meant that travels through the film at an angle that is more oblique than can be achieved by illumination from air using a flat, smooth air/film interface.

    摘要翻译： 膜结构（610）包括一组微层，其反射正常入射的光沿着第一轴偏振，而不是沿着第二轴偏振的正常入射光。 微层布置成光学重复单元（ORU），其具有沿着垂直于第一和第二轴线的厚度轴线的层厚度分布，其为给定的入射条件在延伸的反射带上提供中间反射率的微层。 ORU包括厚度小于平均厚度的更薄的ORU，以及厚度大于平均厚度的较厚ORU。 微组织光学地浸入折射率大于空气的介质中，使得“超临界光”可以传播通过微层。 微层的取向使得平均来说，更薄的ORU比较厚的ORU更接近于结构的输出表面。 “超临界光”是指以比通过使用平坦，平滑的空气/膜界面的空气照明可以实现的倾斜更倾斜的角度穿过膜。

    摘要： A reflector laminate, and backlights and displays incorporating such reflector laminates are disclosed. The reflector laminate includes a substrate and a reflector that are adhered together by a plurality of adhesive protrusions. The adhesive protrusions provide for a plurality of voids between the reflector and the substrate, so that a free reflector surface is adjacent to an air gap between the reflector and substrate. The reflector can include a multilayer interference reflector, and the presence of the air gap ensures high reflectivity for the laminate. The reflector can be adhered to a solid lightguide, a frame enclosing a portion of a backlight, a frame enclosing a hollow lightguide cavity, or an optical sheet positioned at the output surface of a backlight.
