A cover element for an electronic device that includes a glass element having a thickness from 20 μm to 125 μm, a first primary surface, a second primary surface, a compressive stress region extending from the first primary surface to a first depth, and a polymeric layer disposed over the first primary surface. Further, the glass element has a stress profile such that it has a bend strength of about 1850 MPa or more at a 10% failure probability, wherein the cover element is made by a multi-step method that employs a redraw thinning step and at least two chemical etching steps.

Enhanced strength of glass by combining redraw and chemical thinning processes

A glass article including an ultra-thin glass layer and an optically transparent polymeric hard-coat layer having a pencil hardness of 8H or more bonded to the ultra-thin glass layer. The optically transparent polymer hard-coat layer may include an organic polymer material or an aliphatic or aromatic hexafunctional urethane acrylate. In some embodiments, the glass article may have an impact resistance defined by the capability of the glass article to avoid failure at a pen drop height that is 2 times or more than that of a control pen drop height of the ultra-thin glass layer without the optically transparent polymeric hard-coat layer, where the pen drop height and the control pen drop height are measured according to the Pen Drop Test. In some embodiments, the glass article may survive a bend radius of 5 mm or less.

Foldable glass article including an optically transparent polymeric hard-coat and methods of making the same

An article including a laminate having a substrate and an ultra-thin cover glass layer bonded to atop surface of the substrate. The ultra-thin cover glass layer has a thickness in the range of 1 micron to 49 microns. The ultra-thin cover glass layer is bonded to the top surface of the substrate with an optically transparent adhesive layer having a thickness in the range of 5 microns to 50 microns.

Optically transparent fiber glass cover substrates for electronic displays. The cover substrates include an optically transparent fiberglass composite layer including a fiberglass layer embedded in a matrix material and an optically transparent hard-coat layer bonded to a top surface of the optically transparent fiberglass composite layer. A bottom surface of the optically transparent fiberglass composite layer may define a bottommost exterior surface of a cover substrate. The bottommost exterior surface of a cover substrate may be disposed over a display surface of an electronic display to protect the display surface from damage.

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 &#x3c3;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 &#x3c3;at the first primary surface in tension, &#x3c3;+&#x3c3;&#x3c;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.

A flexible glass laminate structure includes a flexible glass substrate having a thickness of no more than 0.3 mm. The flexible glass laminate structure includes a flexible glass layer including the flexible glass substrate. A property control layer is laminated to the flexible glass layer. A neutral axis of the flexible glass laminate is located outside the flexible glass layer when the flexible glass layer is in a compressive bend configuration.
