  • Publication number: 20150077873
    Abstract: Provided are adhesive articles and display components that include a film substrate and an adhesive. The film substrate includes a reflecting layer and an opaque layer. The adhesive may be disposed on at least one major surface of the reflecting layer and opaque layer. The inclusion of the film substrate in the adhesive articles enables the adhesive article to inhibit the transmission of visible light through the film substrate. The film substrate includes at least one cavity extending from the first major surface of the reflecting layer to the first major surface of the opaque layer, wherein the cavity volume is at least partially filled by the adhesive. The display component includes at least one display element adhered to an adhesive article via the adhesive. Methods of making adhesive articles and display components are also provided.

  • Patent number: 7261418
    Abstract: A projection engine uses a first polarizing beam splitter (PBS) that substantially reflects light incident along a first input direction in a first polarization state and substantially transmits light incident in the first input direction in a second polarization state orthogonal to the first polarization state. The first PBS demonstrates an angularly dependent reflectivity for light in the second polarization state that is asymmetric about the first input direction. At least two imager devices are positioned to receive light reflected and transmitted by the first PBS respectively. The imager devices modulate the incident light with an image. The image light from the imagers is combined and projected.

  • Patent number: 6894105
    Abstract: Dyed fluoropolymers that are useful, for example, as conformal coatings comprise the reaction product of one or more fluorochemical (meth)acrylate monomers and one or more (meth)acrylate functional dyes. Coating compositions comprise the dyed fluoropolymer and articles are coated with the coating composition.

  • Patent number: 5674592
    Abstract: Low energy surfaces based on nanostructured films exhibit advancing and receding contact angles for liquids such that (1) the difference between the advancing and receding contact angles approaches zero and (2) the advancing and receding contact angles approach 180.degree.. The low energy surface of the present invention comprises a nanostructured film coated with an organized molecular assembly (OMA). Advantageously, the chemical and wetting characteristics of the surface can be altered by changing the functionality of the OMA end groups exposed to the environment in contact with the surface of the nanostructured film.
