Abstract:
Asymmetrically strengthened glass articles, methods for producing the same, and use of the articles in portable electronic device is disclosed. The asymmetrically strengthened glass articles include glass articles having a deeper compressive stress layer in a thicker portion of the glass article. Using a budgeted amount of compressive stress and tensile stress, asymmetric chemical strengthening is optimized for the utility of a glass article. In some aspects, the strengthened glass article can be designed for reduced damage, or damage propagation, when dropped.
