Abstract: An edge surface includes a first peripheral surface extending between a first major surface and an outer peripheral surface of a substrate. The first peripheral surface includes a first depth and a first width. In aspects, the first depth is from about 4 micrometers to about 12 micrometers, and the first width is from about 30 micrometers to about 50 micrometers. In aspects, the first depth is from about 14 micrometers to about 24 micrometers, and the first width is from about 40 micrometers to about 60 micrometers. In aspects, a ratio of the first depth to a substrate thickness is from about 0.2 to about 0.4, a ratio of the first width to the substrate thickness is from about 1 to about 1.55, and a ratio of the first width to the first depth is from about 2 to about 8.

Abstract: Methods of forming a foldable substrate comprise providing a glass-based substrate comprising a first compressive stress region extending to an existing first depth of compression from an existing first major surface. Methods comprise contacting the existing first major surface with a solution to remove an outer compressive layer of the first compressive stress region to form a new first major surface. The outer compressive layer ranges from about 0.05 micrometers to about 5 micrometers. The solution can comprise a first temperature in a range from about 60° C. to about 120° C. The solution can comprise an alkaline solution comprising about 10 wt % or more of a hydroxide-containing base. In aspects, the method can comprise one or more of: attaching an adhesive layer to the new first major surface, attaching a display device to the new first major surface, or disposing a coating over the new first major surface.
