Abstract: A method for cutting a flexible glass substrate is provided. The method includes directing the flexible glass substrate to a flexible glass cutting apparatus including a laser. The flexible glass substrate includes a first broad surface and a second broad surface that extend laterally between a first edge and a second edge of the flexible glass substrate. A laser beam is directed from the laser onto a region of the flexible glass substrate. A crack is formed through the flexible glass substrate using the laser beam. A local mechanical deformation is formed in the flexible glass substrate using a stress-inducing assembly that includes a stress-inducing feature allowing the flexible glass substrate to deform locally. The crack is propagated along the flexible glass substrate using the laser beam and the local mechanical deformation.

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.
