Abstract: A cover element for an electronic device that includes a glass element having a thickness from 20 ?m to 125 ?m, 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.

Abstract: A cover element for an electronic device that includes a redrawn glass element, first and second primary surfaces, and a polymeric layer disposed over the first primary surface. The redrawn glass element has a reduced thickness and an average surface roughness of 1 nanometer or less. Further, the cover element can withstand a pen drop height of greater than 6 centimeters or 2.5 times or more than that of a control pen drop height of the cover element having a non-redrawn glass element the layer according to Drop Test 1.

Abstract: Methods of manufacturing a glass-based article comprise: exposing an alkali-aluminosilicate glass-based substrate comprising opposing first and second surfaces defining a substrate thickness (t) to an ion exchange treatment to produce an ion exchanged glass-based substrate; and thereafter cooling the ion exchanged glass-based substrate in an environment having a starting temperature that is less than or equal to 200° C. and then reducing the temperature at a rate of greater than or equal to 3.3° C./minute to form the glass-based article.

Abstract: A glass ribbon includes a first major surface extending along a first plane. The glass ribbon includes a second major surface extending along a second plane substantially parallel to the first plane. A first thickness is defined between the first major surface and the second major surface along a thickness direction perpendicular to the first major surface. The first thickness is within a range from about 25 ?m to about 125 ?m. An edge surface extends between the first plane and the second plane. The edge surface comprises a height in the thickness direction that is less than the first thickness. Methods of manufacturing a glass ribbon are also provided.
