  • Publication number: 20150052949
    Abstract: Impact-damage-resistant glass sheet comprising at least one chemically etched surface in combination with a tempering surface compression layer, the glass sheet exhibiting a high standardized ball drop failure height and a high flexural modulus of rupture strength, useful to provide damage-resistant glass cover sheets for consumer electronic video display devices, is provided by subjecting thin glass sheet to a combination of a surface tempering treatment and a surface etching treatment that improves strength while maintaining the optical glass sheet properties required for video display applications.
    Type: Application

  • Patent number: 8771532
    Abstract: A glass article having an anti-glare surface. The anti-glare surface has a distinctness-of-reflected image of less than 95, and a haze of less than or equal to 50%. In one embodiment, the glass article further includes a smudge-resistant surface disposed on the anti-glare surface. Methods of making the glass article and anti-glare surface are also described.

  • Publication number: 20120052302
    Abstract: A method of strengthening an edge of a glass article while maintaining the optical clarity of the major surfaces or protecting layers or structures deposited on the surfaces of the article. A protective coating or film of a polymer or polymer resin is applied to at least one surface of the glass article. The surface may either be melt-derived or polished, and/or chemically or thermally strengthened. The edge is etched with an etchant to reduce the size and number of flaws on the edge, thereby strengthening the edge. A glass article having an edge strengthened by the method is also provided.
