Abstract: 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.

Abstract: Apparatus, systems and methods for improving strength of a thin glass member for an electronic device are disclosed. In one embodiment, the glass member can have improved strength characteristics in accordance with a predetermined stress profile. The predetermined stress profile can be formed through multiple stages of chemical strengthening. The stages can, for example, have a first ion exchange stage where larger ions are exchanged into the glass member, and a second ion exchange stage where some of the larger ions are exchanged out from the glass member. 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.

Abstract: Apparatus, systems and methods for improving chemical strengthening of glass are disclosed. In one embodiment, a mechanical stress can be induced on a glass article while undergoing chemical strengthening. In another embodiment, vibrations, such as ultrasonic vibrations, can be induced during chemical strengthening of a glass article. The use of mechanical stress and/or vibrations during chemically strengthening of a glass article can enhance the effectiveness of the chemical strengthening process. Accordingly, glass articles that have undergone chemical strengthening processing are able to be not only thin but also sufficiently strong and resistant to damage. The strengthened glass articles are well suited for use in consumer products, such as consumer electronic devices (e.g., portable electronic devices).

Abstract: Apparatus, systems and methods for improving chemical strengthening behavior in glass members are disclosed. According to one aspect, a method for processing a glass part formed using a fusion process or a float process includes annealing the glass part and then chemically strengthening the glass part. Annealing the glass part includes at least heating the glass part at a first temperature, maintaining the first temperature, and cooling the glass part to a second temperature using a controlled cooling process. Chemically strengthening the glass part includes facilitating an ion exchange between ions included in the glass part and ions included in a chemical strengthening bath.
