Abstract:
Glass-based articles are disclosed having a thickness in a range of from about 0.2 mm to about 4.0 mm, a first compressive stress layer extending from a first surface of the glass-based article to a first depth of compression that is in a range of from about 5% to about 20% of the thickness, a second compressive stress layer extending from a second surface of the glass-based article to a second depth of compression that is in a range of from about 5% to about 20% of the thickness, wherein the second surface is opposite the first surface, and a central region extending from the first depth of compression to the second depth of compression and having a maximum tensile stress in a range of from about 0.5 MPa to about 20 MPa. Electronic devices comprising the glass-based articles and methods of making glass-based articles are also disclosed.
