Abstract: Optical films having structured surfaces are used, inter alia, for managing the propagation of light within a display. As displays become larger, it becomes more important that the film be reinforced so as to maintain rigidity. An optical film of the invention has a first layer comprising inorganic fibers embedded within a polymer matrix. The first layer has a structured surface to provide an optical function to light passing therethrough. The film may have various beneficial optical properties, for example, light that propagates substantially perpendicularly through the first layer may be subject to no more than a certain level of haze or light incident on the film may be subject to a minimum value of brightness gain. Various methods of manufacturing the films are described.
Abstract translation: 具有结构化表面的光学膜特别用于管理显示器内的光传播。 随着显示器变得越来越大，膜被加固以保持刚性变得更重要。 本发明的光学膜具有包含嵌入聚合物基质内的无机纤维的第一层。 第一层具有结构化表面，以对通过其中的光提供光学功能。 该膜可以具有各种有益的光学性质，例如，基本垂直地传播通过第一层的光可以经受不超过一定水平的雾度，或者入射在该膜上的光可以经受亮度增益的最小值。 描述了制造这些薄膜的各种方法。

Abstract: A backlight (120) that includes a front reflector (130) and a back reflector (160) that form a hollow light recycling cavity (162) having an output surface (164) is disclosed. The front reflector includes at least four directional recycling films (132). The backlight also includes a semi-specular diffuser disposed between the front reflector and the back reflector, and one or more light sources (166) disposed to emit light into the light recycling cavity.

Abstract: A polarizing film is made of multilayer polarizing fibers embedded within a matrix. The fibers are formed with layers of at least a first and a second polymer material. Layers of the first polymer material are disposed between layers of the second polymer material. At least one of the first and second polymer materials is birefringent. Where the fibers are non-circular in cross-section, the cross-section can be oriented within the polarizer.
