First Claim
Patent Images
1. A portable electronic device, comprising:
- a device body having contained in a cavity therein a plurality of device structures, one of the device structures being a display module;
a cover glass disposed at an opening of the device body such that at least one of the plurality of device structures underlies the cover glass; and
an energy absorbing interlayer disposed between the cover glass and at least one underlying device structure, the energy absorbing interlayer having a stiffness that is lower than a stiffness of the cover glass.

Abstract
A portable electronic device includes a device body containing a plurality of device structures, one of which is a display module. A cover glass is disposed at an opening of the device body such that at least one of the plurality of device structures underlies the cover glass. An energy absorbing interlayer is disposed between the cover glass and the at least one underlying device structure, where the energy absorbing interlayer has a stiffness that is lower than that of the cover glass.

15. A cover glass article for a portable electronic device, comprising:
-
a cover glass shaped to at least partially cover an opening of a device body of the portable electronic device, the cover glass being made of a glass or glass-ceramic material having at least one surface under a compressive stress of at least 200 MPa and a compressively stressed layer with a depth of layer of at least 1% of a thickness of the material; and an energy absorbing layer formed on a surface of the cover glass, the energy absorbing layer having a stiffness lower than a stiffness of the cover glass. - View Dependent Claims (16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26)
