Abstract: A cover element for a foldable electronic device that includes a foldable glass element, first and second primary surfaces, and a compressive stress region extending from the first primary surface to a first depth that is defined by a stress σI of at least about 100 MPa in compression at the first primary surface. The device also includes a polymeric layer disposed over the first primary surface. The glass element has a stress profile such that when the glass element is bent to a target bend radius of from 1 mm to 20 mm, to induce a bending stress σB at the first primary surface in tension, σI+σB

Abstract: A strengthened glass article has a chemically-etched edge and a compressive stress layer formed in a surface region thereof. The compressive stress layer has a compressive stress and a depth of layer. A product of the compressive stress and depth of layer is greater than 21,000 μm-MPa. A method of making the strengthened glass article includes creating the compressive stress layer in a glass sheet, separating the glass article from the glass sheet, and chemically etching at least one edge of the glass article.
