Abstract
Embodiments disclosed therein generally pertain to selectively strengthening glass. More particularly, techniques are described for selectively strengthening cover glass, which tends to be thin, for electronic devices, namely, portable electronic devices.
Claims20
A portable electronic device comprising:
- a touch-sensitive layer;
- and
- an enclosure at least partially surrounding the touch-sensitive layer and comprising:
- a housing;
- and
- a glass member coupled to the housing and defining an exterior surface of the enclosure, the glass member comprising:
- an exterior compressive stress region extending from an exterior surface of the glass member to a first depth;
- an interior compressive stress region extending from an interior surface of the glass member to a second depth;
- and
- a peripheral compressive stress region extending between the exterior compressive stress region and the interior compressive stress region and extending from an edge surface of the glass member to a third depth that is greater than the first depth and the second depth.

A portable electronic device comprising:
- an enclosure including a glass member defining a front surface, a rear surface, and an edge surface extending between the front surface and the rear surface, the glass member comprising:
- a front ion-exchanged layer extending from at least a portion of the front surface and defining a front compressive stress region having a first depth from the front surface;
- a rear ion-exchanged layer extending from at least a portion of the rear surface and defining a rear compressive stress region having a second depth from the rear surface;
- and
- a peripheral ion-exchanged layer extending from the edge surface and defining a peripheral compressive stress region having a third depth from the edge surface that is greater than the first depth and the second depth;
- and
- a display positioned within the enclosure and below the glass member.

A portable electronic device comprising:
- a camera;
- and
- an enclosure at least partially surrounding the camera and including a glass member defining:
- a first compressive stress region extending along an exterior surface of the glass member and having a first depth from the exterior surface;
- a second compressive stress region extending along an interior surface of the glass member and having a second depth from the interior surface;
- and
- a third compressive stress region extending along an edge surface of the glass member and having a third depth from the edge surface that is greater than the first depth and the second depth.
