  • Patent number: 8871298
    Abstract: A method for preparing a flexible film substrate with a low glass transition temperature can be used in the production of an article that retains dimensions and improves the surface smoothness after high temperature processing. The invention, for example, would enable low temperature films such as PET and PEN to be dimensionally stable and ultra flat at conditions commonly used in electronic processing which can typically exceed 200° C. More specifically, the methods enable the use of e.g. barrier films based on PET or PEN in OLED/PLED manufacturing.

  • Patent number: 8869740
    Abstract: Disclosed is a method of applying particles to a coated backing. A first layer of particles is created over a second layer of particles on a support surface and the first layer of particles is different in at least one property from the second layer of particles. A coated backing is positioned above the first and second layer of particles. An electrostatic field is applied simultaneously to the first and second layer of particles such that the first layer of particles closer to the coated backing are preferentially attracted to the coated backing first before the second layer of particles.

  • Publication number: 20140313572
    Abstract: A broadband mirror, polarizer, or other reflector includes at least one stack of microlayers. Microlayers in the stack are arranged into optical repeat units. At a design angle of incidence such as normal incidence, the stack provides a 1st order reflection band, a 2nd order reflection band, and optionally a 3rd order reflection band. The 2nd order reflection band overlaps, or substantially overlaps, the 1st and/or 3rd order reflection bands to form a single wide reflection band. The wide reflection band may include the 2nd and 1st but not a 3rd order reflection band, or the 2nd and 3rd but not the 1st order reflection band, or it may include the 1st, 2nd, and 3rd order reflection bands, as well as still higher order reflection bands. The wide reflection band may cover at least a portion of visible and infrared wavelengths.
