Abstract: A glass article comprising an alkali aluminosilicate glass that is formable by down-draw processes for example slot- and fusion-draw to thicknesses of 125 μm or less and is capable of being chemically strengthened by ion-exchange to achieve a compressive stress at its surface of at least 950 MPa, in some embodiments at least about 1000 MPa, and in other embodiments at least about 1100 MPa. The high surface compressive stress allows the glass to retain net compression and thus contain surface flaws when the glass is subjected to bending around a tight radius. The glass may be used in foldable display applications.

Abstract: Foldable apparatus can comprise a first portion comprising a first edge surface defined between a first surface area and a second surface area opposite the first surface area. Foldable apparatus can comprise a second portion comprising a second edge surface defined between a third surface area and a fourth surface area opposite the third surface area. A polymer-based portion can be positioned between the first blunted edge surface and the second blunted edge surface. In some embodiments, the polymer-based portion can comprise a polymer thickness of about 50 micrometers or less measured from the second surface area and/or the first surface area. In some embodiments, the first edge surface and/or the second edge surface can comprise a blunted edge surface. In some embodiments, a coating can be disposed over the first portion, the second portion and the polymer-based portion.
