摘要： 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 σI 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 σB at the first primary surface in tension, σI+σB

摘要： A co-shaped laminate is provided. The laminate includes a first curved glass substrate having a first major surface, a second major surface opposing the first major surface, a first thickness (h1), and a first viscosity (η1) of 1×1011 poises at a first temperature (T1); a second curved glass substrate having a third major surface, a fourth major surface opposing the third major surface, a second thickness (h2), the second thickness being less than the first thickness, and a second viscosity (η2) at the first temperature (T1); and an interlayer disposed between the first curved glass substrate and the second curved glass substrate, wherein the ratio of the first thickness to the second thickness (h1/h2) is greater than about 2.1, and wherein the ratio of the second viscosity to the first viscosity (η2/η1) is between about (h1/h2)2.55 and about (h1/h2)3.45.

摘要： A system and process for forming a curved glass laminate article is provided. The process and system utilizes a separation material, such as solid lubricating material and/or a spray applied separation material that Applicant has determined reduces bending dot formation during co-sagging shaping of glass sheets. The bending dot reduction provided by the separation materials discussed herein is particularly seen when the pair of glass sheets have significantly different thicknesses and/or viscosities from each other.
