Abstract: Methods of making ion-exchanged glass articles including exposing the glass articles to a molten salt including 2 wt % to 10 wt % of an inorganic non-hydroxide salt sufficient to provide a pH from 9 to 12 when 5 grams of the inorganic non-hydroxide salt is dissolved in 100 grams of distilled water. The high-pH molten salts comprising the inorganic non-hydroxide salt can ion-exchange thin glass articles to have desirable mechanical performance without the use of a post-ion-exchange etching step. In some embodiments, the molten salt can include less than 1 wt % sodium nitrate (NaNO3).

Abstract: Foldable substrates comprise a first portion, a second portion, and a central portion positioned therebetween. The central portion comprises a first central surface area recessed from a first major surface by a first distance and a second central surface area. A second major surface comprises the second central surface area. A blunted edge extends around an entire periphery of the foldable substrate. The blunted edge comprising a first blunted surface area where the blunted edge meets the first major surface and a second blunted surface area where the blunted edge meets the second major surface. Methods comprise laminating the foldable substrate with support layers before removing a peripheral portion of an initial edge of the foldable substrate to form an intermediate edge. The intermediate edge is contacted with an etchant to form the blunted edge. Methods further comprise removing the support layers from the foldable substrate.

Abstract: Foldable substrates comprise a first outer layer comprising a first major surface, a second outer layer comprising a second major surface, and a core layer positioned therebetween. The core layer may comprise a first central surface area positioned between a first portion and a second portion of the first outer layer, and the core layer comprising a second central surface area positioned between a third portion and fourth portion of the second outer layer. Some foldable substrates comprise a first portion comprising a first depth of compression, a first depth of layer, and a first average concentration. The central portion may comprise a first central depth of compression, a first central depth of layer, and a central average concentration. Methods comprise chemically strengthening a foldable substrate. Some methods comprise etching the foldable substrate and then further chemically strengthening the foldable substrate.

Abstract: Polymer-based portions comprise an index of refraction ranging from about 1.49 to about 1.55. In some embodiments, the polymer-based portion comprises the product of curing 45-75 wt % of a difunctional urethane-acrylate oligomer with 25-55 wt % of a difunctional cross-linking agent and optionally a reactive diluent. In some embodiments, the polymer-based portion comprises the product of curing 75-100 wt % of a reactive diluent and optionally one or more a difunctional urethane-acrylate oligomer and/or a difunctional cross-linking agent. Adhesives comprise an index of refraction ranging from about 1.49 to about 1.55. In some embodiments, the adhesive comprises the product of heating 10-35 wt % of a silane-hydride-terminated siloxane and 65-90 wt % of a vinyl-terminated siloxane. In some embodiments, the adhesive comprises the product of irradiating a thiol-containing siloxane and a photo-initiator with at least one wavelength of light that the photo-initiator is sensitive to. Foldable apparatus can comprise the polymer-based portion and/or adhesive.

Abstract: Foldable apparatus can comprise a foldable substrate comprising a substrate thickness and a central portion positioned between a first portion and a second portion. The central portion can comprise a central thickness less than the substrate thickness. A first maximum tensile stress of a first tensile stress region in the first portion and a second maximum tensile stress of the second tensile stress region in the second portion can be less than a third maximum tensile stress of a central tensile stress region in the central portion. Ribbons can comprise a ribbon thickness and a central portion positioned between a first portion and a second portion. The central portion can comprise a first central compressive stress region and a second central compressive stress region. In some embodiments, methods of processing a ribbon can comprise masking the first portion, masking the second portion, and chemically strengthening the central portion.
