Abstract: Foldable substrates comprise a substrate thickness from about 80 micrometers to about 2 millimeters. Foldable substrates comprise a first portion, a second portion, and a central portion positioned therebetween. The central portion comprises a central thickness from about 25 micrometers to about 80 micrometers defined between a first central surface area and a second central surface area. A central total thickness variation of the central portion over the first central surface area is less than or equal to 10 micrometers. The central portion comprises a first transition region extending between a first surface area of the first portion and the first central surface area. The first central surface area is recessed from the first major surface by a first distance. A thickness of the first transition region smoothly and monotonically decreases between the substrate thickness of the first portion and the central thickness of the central portion.

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: Methods are provided for measuring the asymmetry of glass-sheet manufacturing processes. The methods include subjecting glass sheets or test samples taken from glass sheets to an ion-exchange process and measuring warp values. Metrics for the asymmetry of the glass-sheet manufacturing process are then obtained from the warp values. In one embodiment, the metric is independent of the geometry of the glass sheets or the test samples (the BM1 metric); in another embodiment, the metric is independent of the geometry of the glass sheets or the test samples and substantially independent of the ion-exchange process used in the testing (the ASYM metric).
