Abstract: Disclosed devices (100) include a liquid crystal layer (140), a cover glass (105), a polarizer (115), and at least one anti-static coating disposed on at least one major surface (105A, 105C) of the cover glass, at least one major surface (115A, 115C) of the polarizer, or both. Methods for reducing mura (light leakage) in a touch-display device by means of this anti-static coating are also disclosed.

Abstract: Apparatus and methods for processing a glass sheet can include a coating chamber including a dispensing port to dispense a coating on a major surface of the glass sheet. In some embodiments, an apparatus can include a fog chamber including an enclosure, a fog generator to provide fog to the enclosure, and a passage in the enclosure from which fog can exit the enclosure to contact a major surface of the glass sheet. In some embodiments a method can include providing a glass sheet to a coating chamber, and dispensing a coating on a major surface of the glass sheet. In some embodiments, a method can include providing a glass sheet to a fog chamber, providing fog to an enclosure of the fog chamber, and contacting a major surface of the glass sheet with the fog by passing the fog from the enclosure through a passage in the enclosure.

Abstract: Methods of manufacturing a glass-based article comprise: after mechanical polishing of a glass-based substrate, treating at least one surface of the glass-based substrate for protection of the at least one surface from contamination and/or for removal of contaminants from the at least one surface by a treatment other than ultrasonic cleaning; and exposing the glass-based substrate to an ion exchange treatment after the treating step to form the glass-based article. The treating step includes: exposing the at least one surface to a high pH soaking for removal of contaminants; deionizing the at least one surface for removal of contaminants; and/or applying a temporary coating to the at least one surface for protection of the at least one surface from contamination, and removing the temporary coating prior to the ion exchange treatment step. The ion exchange treatment may comprise a molten salt bath having an increased pH and temperature.

Abstract: A substrate with a textured surface is disclosed. The substrate may be, for example, a light emitter comprising a light guide, for example a backlight element for use in a display device, wherein a surface of the light guide, for example a glass substrate, is configured to have a textured surface with a predetermined RMS roughness and a predetermined correlation length of the texture. A plurality of light scatter suppressing features can be provided on the textured surface. Textured surfaces disclosed herein may be effective to reduce electrostatic charging of the substrate surface. Methods of producing the textured surface are also disclosed.

Abstract: Glass substrates comprising an A-side upon which silicon thin film transistor devices can be fabricated and a B-side having a substantially homogeneous organic film thereon are described. The organic film includes a moiety that reduces voltage generation by contact electrification or triboelectrification. Methods of manufacturing the glass substrates and example devices incorporating the glass substrates are also described.

Abstract: Methods of producing a glass sheet each comprise the step of creating a vacuum to force the entire lateral portion of the glass ribbon to engage an anvil portion of a breaking device in the elastic zone. The vacuum is provided by a plurality of pressure zones that are operated independent from one another, wherein each pressure zone is provided with a set of suction cups. In further examples, glass ribbon breaking devices each include a plurality of pressure zones that are configured to be operated independent from one another with each pressure zone being provided with set of suction cups.
