    Abstract: Electronic devices may be provided with displays that have polarizers. A polarizer may have a polymer layer that has a portion covered with a dichroic dye to form a polarized region and a portion that is free of dichroic dye to form an unpolarized region. The unpolarized region may be formed by masking the polymer layer during a dye coating process. Masks may be formed from polymers. The shape of the mask may define the shape of the unpolarized region. The mask may be left in place within the polarizer or may be removed from the polarizer during fabrication. Unpolarized regions may also be formed by light bleaching, chemical bleaching, and material removal techniques. Bleached areas may be chemically stabilized. A moisture barrier layer may be incorporated into the polarizer to help prevent the unpolarized region from reverting to a polarized state.

  • Patent number: 8857372
    Abstract: An isothermal, low pressure-based process of depositing material within a substrate has been developed and results in creating an extremely narrow reaction zone within which a more uniform and efficient deposition will occur. Sets of isothermal plasma operating conditions have been found that create a narrow deposition zone, assuring that the deposited material is clear glass rather than soot particles. The chemical delivery system, in one arrangement, utilizes rods of solid phase source material (which may otherwise be difficult to obtain in gaseous form). The operating conditions are selected such that the hot plasma does not transfer a substantial amount of heat to the substrate tube, where the presence of such heat has been found to result in vaporizing the reactant material (creating soot) and developing hot spots.

  • Patent number: 8852678
    Abstract: Glass surfaces, for example, windshield surfaces, have a durable hydrophobic coating applied thereto. The glass surface is first treated by any suitable method to enhance the ability of a chitosan polymer coating to durably or substantially permanently adhere thereto. Once the chitosan coating has been applied to the glass surface, the normally hydrophilic chitosan coating is rendered hydrophobic by suitable treatment, for example, by a combination of enzymatic and chemical treatments. Alternatively, the chitosan may be rendered hydrophobic prior to coating it on the glass surface, but that is a less preferred technique. The method of the invention provides a glass article having a hydrophobic surface.

  • Publication number: 20140272338
    Abstract: Certain example embodiments relate to a method of making a coated article and/or glazing (e.g., for automobile, window, and/or other applications). An opaque paint that is not technically a frit is used to form a desired opaque pattern. The paint is screen printed on a substrate. Screen printing parameters are selected, e.g., so that the mesh has a high threads per inch count; the paint is pushed through the screen using hydraulic forces that account for a sheer thinning property of the paint by balancing squeegee speed, squeegee angle relative to the screen, and hardness of the squeegee; and/or relative humidity above and/or near the screen is at least about 80%. Preferably, the paint is substantially fully curable at 400 degrees C. or less. The substrate with the pattern thereon may be bent using a high temperature process, optionally with another substrate to which it may be laminated.

  • Publication number: 20140254011
    Abstract: A wire grid polarizer formed as a self-assembled coating on a substrate surface. Metal or other conductive nanowires are coated with a transparent dielectric material having a thickness approximately equal to one-half of the desired WGP wire spacing or pitch. A suspension of coated nanowires in a chromonic liquid crystal is shear-coated onto an aligned substrate and dried. The chromonic liquid crystal, a solution of dye molecules and water, forms an orderly structure and induces the nanowires to align with their longitudinal axes parallel to the shear direction and/or alignment direction. The polarizer has a minimum polarizing wavelength determined by an average lateral spacing of nanowire segments. The polarizer has a transmissivity and a contrast ratio determined by the width of the nanowire segments.

  • Patent number: 8821966
    Abstract: A method for manufacturing an image display device includes the step of forming a cured resin layer by interposing a photo-curable resin composition between a protection member and a display-side panel including an image display unit and a frame member and then photo-curing the photo-curable resin composition, with the photo-curable resin composition being disposed across between the image display unit and the frame member. In the manufacturing method, a high-viscosity resin composition having a viscosity of 3000 mPa·s or more and 12000 mPa·s or less is used as the photo-curable resin composition. Alternatively, after a gap between the image display unit and the frame member is sealed with a sealing film, a photo-curable resin composition is interposed between the display-side panel and the protection member.
