DAMAGE RESISTANT GLASS ARTICLE FOR USE AS A COVER PLATE IN ELECTRONIC DEVICES

摘要

An alkali aluminosilicate glass article, said alkali aluminosilicate glass having a surface compressive stress of at least about 200 MPa, a surface compressive layer having a depth of at least about 30 µm, a thickness of at least about 0.3 mm and an amphiphobic fluorine-based surface layer chemically bonded to the surface of the glass. In one embodiment the glass has an anti reflective coating applied to one surface of the glass between the chemically strengthened surface of the glass and the amphiphobic coating. In another embodiment the surface of the chemically strengthened glass is acid treated using a selected acid (e.g., HCL, H2SO4, HClO4, acetic acid and other acids as described) prior to placement of the amphiphobic coating or the anti reflective coating.
