Embodiment Construction

[0030] The present invention generally relates to increasing the strength of glass. Glass with increased strength can be thinned and still be strong enough to be suitable for use in electronic devices, such as portable electronic devices.

[0031] The following detailed description is illustrative only and is not intended to be limiting in any way. Other implementations will readily occur to those skilled in the art having the benefit of this disclosure. Reference is now made in detail to the implementations as illustrated in the accompanying drawings.

[0032] In the interest of clarity, not all of the routine features of the implementations described herein are shown and described. Of course, it will be recognized that in the development of any such actual implementation, a variety of implementation-specific decisions must be made in order to achieve the developer's specific goals, such as compatibility with application and enterprise-related constraints, and that these sp...

Abstract

An 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.

Description

[0001] CROSS REFERENCE TO OTHER APPLICATIONS [0002] This application claims priority to: (i) U.S. Provisional Patent Application No. 61 / 300,793, filed February 2, 2010, and entitled "TECHNIQUES FOR STRENGTHENING GLASS COVERS FOR PORTABLE ELECTRONIC DEVICES," which is hereby incorporated as and (ii) US Provisional Patent Application No. 61 / 300,792, filed February 2, 2010, and entitled "TECHNIQUES FOR STRENGTHENING GLASS COVERS FOR PORTABLE ELECTRONIC DEVICES," which application is hereby incorporated by reference. Background technique [0003] Traditionally, small form factor devices, such as handheld electronic devices, have display arrangements comprising various layers. These various layers typically include at least a display technology layer and may additionally include a sensing arrangement and / or a cover window located above said display technology layer. As an example, a display technology layer may include or relate to a liquid crystal display (LCD) including a liqu...
