Abstract: Foldable apparatus comprise a foldable substrate comprising a substrate thickness. The second major surface of the foldable substrate faces an end portion of a first inner surface area of a first housing member extending along a first plane. The second surface faces an end portion of a second inner surface area of a second housing member extending along a second plane. A support is attached to at least the second housing member. The support contacts the second major surface when an angle between the first plane and the second plane ranges from about 80° to about 135°. The support is spaced from the second major surface when an angle between the first plane and the second plane ranges from about 0° to about 30°. In some embodiments, the foldable substrate comprises a neutral stress configuration at a parallel plate distance ranging from about 20 millimeters to about 200 millimeters.

Abstract: Glasses with compressive stress profiles that allow higher surface compression and deeper depth of layer (DOL) than is allowable in glasses with stress profiles that follow the complementary error function at a given level of stored tension. In some instances, a buried layer or local maximum of increased compression, which can alter the direction of cracking systems, is present within the depth of layer. Theses compressive stress profiles are achieved by a three step process that includes a first ion exchange step to create compressive stress and depth of layer that follows the complimentary error function, a heat treatment at a temperature below the strain point of the glass to partially relax the stresses in the glass and diffuse larger alkali ions to a greater depth, and a re-ion-exchange at short times to re-establish high compressive stress at the surface.
