More Information
Summary:Techniques for improving strength of a thin glass cover for an electronic device are disclosed. The glass member can have improved strength by chemical strengthening in a series of stages. The stages can, for example, have a first ion exchange stage where larger ions are exchanged into the glass cover, and a second ion exchange stage where some of the larger ions are exchanged out from the glass cover. The glass cover can improve its strength by forming its edges with a predetermined geometry. Advantageously, the glass cover can be not only thin but also adequately strong to limit susceptibility to damage. The glass member pertains to a glass cover for a housing for an electronic device. The glass cover can be provided over or integrated with a display, such as a Liquid Crystal Display (LCD) display.
