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 σ I  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 σ B  at the first primary surface in tension, σ I +σ B <400 MPa (in tension). Further, the cover element can withstand a pen drop height of at least 1.5 times that of a control pen drop height of the cover element without the layer according to a Drop Test 1.

Claim (Index 28):
A foldable electronic device assembly, comprising:\n a foldable electronic device substrate; a foldable glass element disposed over the device substrate, the glass element comprising a thickness from about 25 \u03bcm to about 200 \u03bcm and further comprising:\n (a) a first primary surface, \n (b) a second primary surface, and \n (c) a compressive stress region extending from the first primary surface of the glass element to a first depth in the glass element, the region defined by a stress \u03c3 I  of at least about 100 MPa in compression at the first primary surface of the glass element; and \n a polymeric layer comprising a thickness from about 10 \u03bcm to about 100 \u03bcm and disposed over the first primary surface of the glass element, wherein the glass element is characterized by a stress profile such that when the glass element is bent to a target bend radius of from 1 mm to 20 mm, with the center of curvature on the side of the second primary surface so as to induce a bending stress \u03c3 B  at the first primary surface (in tension), \u03c3 I +\u03c3 B <400 MPa (in tension), wherein the foldable electronic device assembly comprises an ability to resist permanent warp such that a permanent warp of the foldable electronic device assembly is at least 10% lower than a permanent warp of a comparable foldable electronic device assembly, wherein the permanent warp of the device assemblies is measured according to a Static Test after a hold time on test of 480 hours at 85\u00b0 C. and 85% relative humidity, and further wherein the comparable foldable electronic device assembly comprises (a) a comparable substrate and comparable polymeric layer comprising the same dimensions and compositions as the respective substrate and polymeric layer of the foldable electronic device assembly, and (b) a comparable foldable polymeric element disposed between the comparable substrate and comparable polymeric layer that comprises a polyimide (PI) comprising the same, or a smaller, thickness as the glass element of the foldable electronic device assembly.
