Abstract
Embodiments of the disclosure relate to a rollable glass sheet configured to reversibly transition between a flat configuration and a bent configuration. The rollable glass sheet includes a first major surface and a second major surface opposite to the first major surface. The first major surface and the second major surface define a thickness of the glass sheet that is 0.4 mm or less. In the flat configuration, the first major surface includes a first surface compressive stress and a first depth of compression, and in the bent configuration, the first major surface includes a curvature. At a radius of curvature of 50 mm, the first major surface includes a second surface compressive stress less than the first compressive stress and a second depth of compression less than the first depth of compression and greater than 11 μm.
