Abstract: A foldable electronic device module includes: a glass-containing cover element having a thickness from about (25) μm to about (200) μm, an elastic modulus from about (20) to (140) GPa, and first and second primary surfaces; a stack comprising: (a) an interlayer having an elastic modulus from about (0.01) to (10) GPa and a thickness from about 50 to (200) μm, and (b) a flexible substrate having a thickness from about (100) to (200) μm; and a first adhesive joining the stack to the cover element, and comprising an elastic modulus from about (0.001) to (10) GPa and a thickness from about (5) to (25) μm. Further, the module comprises an impact resistance characterized by tensile stresses of less than about (4100) MPa and less than about (8300) MPa at the first and second primary surfaces of the cover element, respectively, upon an impact in a Pen Drop Test.

Abstract: A laminated glass article includes a glass core layer having a core modulus Ecore and a glass cladding layer adjacent to the core layer and having a cladding modulus Eclad. Eclad can be at least 5 GPa less than Ecore. A modulus ratio Ecore/Eclad can be at least 1.08. The cladding layer can have a compressive stress resulting from a coefficient of thermal expansion (CTE) contrast between the core layer and the cladding layer and/or subjecting the laminated glass article to an ion exchange treatment to form an ion exchanged region at an outer surface of the cladding layer.

Abstract: A glass sleeve assembly for a portable electronic device may comprise a glass sleeve extending longitudinally from a first opening defined by a first rim to a second opening defined by a second rim. The glass sleeve may have an internal surface. A first end cap may be positioned adjacent to the first opening and may have at least a portion extending longitudinally beyond the first rim. A second end cap may be positioned adjacent to the second opening and may have at least a portion extending longitudinally beyond the second rim. A frame may comprise first and second ends and a central portion between the first and second ends. The central portion may be located within the glass sleeve. The ends of the frame may be connected to the end caps. Shock absorbing interlayers may be mounted to the end caps and the glass sleeve.

Abstract: A substrate having inner and outer major surfaces, a plurality of edge surfaces, and a plurality of corner surfaces; and at least one of: (i) a coating applied over a limited area of the outer major surface of the substrate to produce a composite structure, (ii) an intermediate layer applied to the inner major surface of the substrate, and (iii) an elongate discontinuity disposed at one or more corners of the substrate, each of which operates to reduce catastrophic failures in the substrate resulting from a dynamic sharp impact to the outer major surface of the substrate.
