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.
Claims21
1-20. (canceled)
A system for a portable electronic device, the system comprising:
- a cover glass configured to be positioned over a display of the portable electronic device, the cover glass comprising:
- a front compressive stress region having a first depth from at least a portion of a front surface of the cover glass;
- a rear compressive stress region having a second depth from at least a portion of a rear surface of the cover glass;
- and
- a peripheral compressive stress region extending between the front compressive stress region and the rear compressive stress region, the peripheral compressive stress region having a third depth, greater than the first depth and the second depth, from an edge surface of the cover glass.
2 more elements
A cover glass defining:
- a front surface;
- a rear surface;
- an edge surface extending between the front surface and the rear surface;
- a front compressive stress region extending from a first portion of the front surface to a first depth;
- a rear compressive stress region extending from a first portion of the rear surface to a second depth;
- and
- a peripheral compressive stress region extending from a second portion of the front surface, from a second portion of the rear surface, and from the edge surface, the peripheral compressive stress region having a third depth from the edge surface that is greater than the first depth and the second depth.
4 more elements
A cover assembly comprising:
- a glass member defining:
- a first compressive stress region extending to a first depth from a first surface of the glass member;
- a second compressive stress region extending to second depth from a second surface of the glass member that is opposite to the first surface;
- and
- a third compressive stress region extending to a third depth, greater than the first depth and the second depth, from a third surface of the glass member, the third surface extending between the first and the second surfaces and defining an edge of the glass member.
