Abstract: An apparatus and method for bending and/or tempering glass substrate(s) are provided. The amount of near-IR radiation which reaches the glass to be bent and/or tempered is limited (e.g., via filtering or any other suitable technique). Thus, the IR radiation (used for heating the glass) which reaches the glass to be bent and/or tempered includes mostly mid-IR and/or far-IR radiation, and not much near-IR. In such a manner, coating(s) provided on the glass can be protected and kept at lower temperatures so as to be less likely to be damaged during the bending and/or tempering process. Heating efficiency can be improved.

Abstract: An apparatus and method for bending glass substrate(s) are provided. Microwave radiation is used to heat glass substrate(s) for bending. As a result, a coating supported by the substrate(s) is not heated as much during the bending process compared to if only conventional IR radiation was used. Thus, more extreme degrees of glass bending may be achieved, and/or the likelihood of coating damage reduced.

Abstract: The present invention provides a method of forming a glass article having a transparent hydrophobic surface during a glass-forming operation. In accordance with the method, a plurality of solid particles of inorganic material having an average diameter of less than about 400 nm are applied to a surface of the glass article when the glass article is at a temperature within the range of from about 700° C. to about 1200° C. The inorganic particles fuse to the surface of the glass article to form the transparent hydrophobic surface. Optionally, a fluorosilane agent can be applied to the transparent hydrophobic surface to further increase its hydrophobicity. The transparent hydrophobic surface has a nano-structured texture, which makes the surface of the glass article very hydrophobic and easy to clean.

Abstract: An index-matching coating is applied directly to a low-emissivity (“lowE”) thin-film coating. Nodules growing from a site in the lowE coating are removed to avoid propagation of defects through the layers of the index-matching coating. A tempering step in an oxygen-containing atmosphere produces compressive stress in the lowE coating and hardens the coating. The compressive stress facilitates removal of the nodules and the hardening allows mechanical cleaning of the lowE coating prior to the index-matching coating, further removing nodules. Magnesium-fluoride is used as the final layer of the index-matching coating in one embodiment to improve abrasion resistance. The resulting glass panel may be used as a display panel in a plasma display or an organic light-emitting diode display, for example.

Abstract: A soda inclusive glass substrate is coated with a highly tetrahedral amorphous carbon inclusive layer that is a form of diamond-like carbon (DLC). In certain embodiments, the amorphous carbon layer includes at least about 35% sp3 carbon-carbon bonds, more preferably at least about 70%, and most preferably at least about 80% of the sp3 carbon-carbon bonds. The high density (e.g. greater than or equal to about 2.4 gm/cm3) of the amorphous carbon layer prevents soda from exiting the glass and reacting with water at surface(s) of the glass, thereby minimizing visible stains (or corrosion) on the glass. The high density amorphous carbon layer also may repel water. In some embodiments, the highly tetrahedral amorphous carbon layer is part of a larger DLC coating, while in other embodiments the highly tetrahedral layer forms the entirety of a DLC coating on the substrate.

The substrate includes glass substrates, including glass sheet and continuous float glass ribbon.
