Abstract
Differentially strengthened cover members for electronic devices are disclosed. The differentially strengthened cover members include at least one chemically strengthened zone that improves the resistance of the cover member to cracking. In some examples, one or more of the chemically strengthened zones covers or at least partially surrounds a portion of the cover member to be protected from damage.
