  • Publication number: 20070236939
    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.

  • Publication number: 20070141739
    Abstract: Disclosed herein is a method of making a light emitting device comprising an LED and a molded silicon-containing encapsulant. The method includes contacting the LED with a photopolymerizable composition containing a silicon-containing resin having silicon-bonded hydrogen and aliphatic unsaturation and two metal-containing catalysts. One catalyst may be activated by actinic radiation, and the second by heat but not the actinic radiation. Polymerization of the photopolymerizable composition to form the encapsulant may be carried out by selectively activating the different catalysts. At some point before polymerization is complete, a mold is used to impart a predetermined shape to the encapsulant.
