Abstract: A foldable electronic device module includes a glass cover element having a thickness from about 25 μm to about 200 μm, an elastic modulus from about 20 GPa to about 140 GPa and a puncture resistance of at least 1.5 kgf. The module further includes a stack with a thickness between about 100 μm and about 600 μm; and a first adhesive joining the stack to the cover element with a shear modulus between about 1 MPa and about 1 GPa. The stack further includes a panel, an electronic device, and a stack element affixed to the panel with a stack adhesive. Further, the device module is characterized by a tangential stress at a primary surface of the cover element of no greater than about 1000 MPa in tension upon bending the module to a radius from about 20 mm to about 2 mm.

Abstract: Glass articles comprising an outer region extending from an outer surface of the glass article to a depth of layer and methods of making the same are described. The outer region is bounded by at least one edge of the glass article and is under an intrinsic neutral stress or an intrinsic compressive stress. A core region of the glass article is under a tensile stress. A compressive element applies an external compressive stress to the at least one edge and increases the intrinsic stress on the outer region and reduces the tensile stress in the core region of the glass article. The glass article may be a strengthened glass article such that the outer region is under compressive stress, and the external compressive stress applied by the compressive element has a magnitude such that the glass article has an overall internal stress defined by: ∫0tσdt≠0 where t is a thickness of the glass article and σ is the internal stress.
