Bendable glass stack assemblies, articles and methods of making the same

摘要

A glass element having a thickness from 25 μm to 125 μm, a first primary surface, a second primary surface, and a compressive stress region extending from the first primary surface to a first depth, the region defined by a compressive stress σI of at least about 100 MPa at the first primary surface. Further, the glass element has a stress profile such that it does not fail when it is held at a bend radius from about 1 mm to about 20 mm for at least 60 minutes at about 25° C. and about 50% relative humidity. Still further, the glass element has a puncture resistance of greater than about 1.5 kgf when the first primary surface of the glass element is loaded with a tungsten carbide ball having a diameter of 1.5 mm.

1. A glass article, comprising:
a glass element having a thickness from about 50 μm to about 125 μm, the glass element further comprising: (a) a first primary surface; (b) a second primary surface; and (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 compressive stress of at least about 700 MPa at the first primary surface of the glass element, wherein the glass element is characterized by: (a) an absence of failure when the glass element is held at a bend radius from about 3 mm to about 10 mm for at least 60 minutes at about 25° C. and about 50% relative humidity; (b) a puncture resistance of greater than about 1.5 kgf when the first primary surface of the glass element is loaded with a tungsten carbide ball having a diameter of 0.5 mm.
