LAMINATED ALUMINUM OXIDE COVER COMPONENT
First Claim
1. A cover glass for an electronic display, the cover glass comprising:
- a plurality of layers of substantially single-crystal sapphire, each of the layers having a substantially single crystal plane orientation, wherein adjacent layers of the substantially single-crystal sapphire have different substantially single crystal plane orientations;
one or more interface layers defined between the adjacent layers of substantially single-crystal sapphire, wherein the adjacent layers of substantially single-crystal sapphire are bonded together at the one or more interface layers; and
a display window defined in the cover glass, the display window configured for viewing the electronic display through the plurality of layers of substantially single crystal sapphire bonded together at the one or more interface layers.

Abstract
A cover glass for an electronic display comprises a plurality of layers of sapphire material, each of the layers having a substantially single crystal plane orientation, with adjacent layers having different substantially single crystal plane orientations. One or more interface layers are defined between adjacent layers of the sapphire material, with the adjacent layers of sapphire material bonded together at the one or more interface layers. A display window is defined in the cover glass, and configured for viewing a viewable area of the electronic display through the plurality of layers of the sapphire material bonded together at the one or more interface layers.

13. A device comprising:
-
a display; a frame disposed about the display; a back cover coupled to a back of the frame and positioned behind the display; a front glass coupled to a front of the frame and positioned in front of the display, the front glass comprising a plurality of substantially single crystal sapphire layers having substantially single crystal plane orientations, wherein the plurality of sapphire layers are bonded together to form the front glass such that the substantially single crystal plane orientations of adjacent sapphire layers are different; and a substantially transparent display window defined in the front glass, the display window configured for viewing the display through the plurality of sapphire layers. - View Dependent Claims (14, 15, 16, 17, 18, 19)
