A method for strengthening a glass cover for an electronic device is disclosed, where the method comprises chemical strengthening in a series of stages. The stages can have a first ion exchange stage using heated solutions (melts) 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 region of peak compressive strength 1028 occurs at a distance below the treated surface. Optionally, the glass cover can have its strength increased by forming its edges with a predetermined curved or chamfered geometry. In one embodiment, the glass member can pertain 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 Liquid Crystal Display (LCD) display. |
