This method is a method for producing an optically anisotropic laminated body including a substrate, an oriented film, and an optically anisotropic film, and has steps of: applying, to a surface of the substrate, an oriented-film-forming composition including an oriented-film-forming material and a solvent and having a viscosity of 4 mPa·s or less at 25° C., and drying the resultant to form the oriented film; and then applying, onto the resultant oriented film, an optically-anisotropic-layer-forming composition including a polymerizable liquid crystal compound, and drying the resultant to orient the polymerizable liquid crystal compound vertically to the surface of the substrate to form the optically anisotropic film.Type: ApplicationFiled: August 7, 2014Publication date: February 12, 2015Applicant: SUMITOMO CHEMICAL COMPANY, LIMITEDInventor: Tadahiro KOBAYASHI

Publication number: 20150026951Abstract: Methods of forming polarized panes for variable transmission windows are disclosed. The polarized panes are formed from transparent substrates that are brushed with a brushing pattern that varies continuously in a select direction over each of one or more periods. A layer of polarizable material such as POLARCOAT material can be deposited on and responds to the brushed surface by forming a polarization pattern that substantially matches the brushing pattern and thus also includes one or more periods.Type: ApplicationFiled: July 24, 2013Publication date: January 29, 2015Applicant: CORNING INCORPORATEDInventor: Timothy James Orsley

Patent number: 8927069Abstract: A method and apparatus for modifying low emissivity (low-E) coated glass, so that windows using the processed glass allow uninterrupted use of RF devices within commercial or residential buildings. Glass processed in the manner described herein will not significantly diminish the energy conserving properties of the low-E coated glass. This method and apparatus disrupts the conductivity of the coating in small regions. In an embodiment, the method and apparatus ablates the low-E coating along narrow contiguous paths, such that electrical conductivity can no longer occur across the paths. The paths may take the form of intersecting curves and/or lines, so that the remaining coating consists of electrically isolated areas. The method and apparatus are applicable both to treating glass panels at the factory as well as treating windows in-situ after installation.Type: GrantFiled: October 2, 2013Date of Patent: January 6, 2015Assignee: Eritek, Inc.Inventors: Eugenio Estinto, Robert Winsor

Publication number: 20150002791Abstract: A polarizer includes a base substrate and a dielectric stacked layer. The dielectric stacked layer in includes a first dielectric layer and second dielectric layer. The first dielectric layer has a high refractive index and a second dielectric layer has a low refractive index. A wire grid pattern is disposed on the dielectric stacked layer. The wire grid pattern has a line width, a separation distance and a pitch. The pitch is a sum of the line width and the separation distance. Adjacent grids of the wire grid pattern are spaced apart by the separation distance.Type: ApplicationFiled: December 17, 2013Publication date: January 1, 2015Applicant: SAMSUNG DISPLAY CO., LTD.Inventors: Jung-Gun NAM, Moon-Jung AN, Dae-Young LEE, Dae-Hwan JANG, Gug-Rae JO, Atsushi TAKAKUWA

Patent number: 8906206Abstract: The invention provides a coater, and methods of using the coater, for depositing thin films onto generally-opposed major surfaces of a sheet-like substrate. The coater has a substrate transport system adapted for supporting the substrate in a vertical-offset configuration wherein the substrate is not in a perfectly vertical position but rather is offset from vertical by an acute angle. The transport system defines a path of substrate travel extending through the coater. The transport system is adapted for conveying the substrate along the path of substrate travel. Preferably, the transport system includes a side support for supporting a rear major surface of the substrate. The preferred side support bounds at least one passage through which coating material passes when such coating material is deposited onto the substrate's rear major surface. Preferably, the coater includes at least one coating apparatus (e.g.Type: GrantFiled: February 26, 2010Date of Patent: December 9, 2014Assignee: Cardinal CG CompanyInventor: Klaus Hartig
