LAMINATED DISPLAY WINDOW AND DEVICE INCORPORATING SAME
First Claim
1. A laminated window assembly for a device, said assembly comprising:
- a window layer comprising a first substantially transparent material and having a periphery;
a lip-forming layer larger than said window layer and comprising a second substantially transparent material, said lip-forming layer extending beyond said window layer to form a lip for engaging said device;
a substantially transparent bonding layer between said window layer and said lip-forming layer; and
an adhesive bead bonding said window layer to said lip-forming layer along at least one portion of said periphery.

Abstract
A laminated window assembly for a device, such as a handheld electronic device (e.g., a media player or mobile telephone), includes a window layer that preferably is glass, and a larger, substantially transparent lip-forming layer to which it is laminated, preferably by a substantially clear adhesive. Additional adhesive preferably is placed at at least portions of the edge of the window layer adjacent the lip-forming layer, especially at the corners, to resist delamination. Holes preferably are formed in the lip—e.g., at the corners—to resist the lip-forming layer peeling apart from the window layer forming layer. The holes preferably make up at most about 33% of the periphery of the window layer.

18. A device comprising:
-
a casing, said casing having a face portion, said face portion having a window opening therein; and a laminated window assembly, said laminated window assembly comprising; a window layer comprising a first substantially transparent material and having a periphery, said window layer being substantially identical in size and shape to said opening; a lip-forming layer larger than said window layer and comprising a second substantially transparent material, said lip-forming layer extending beyond said window layer to form a lip for engaging said device; a substantially transparent bonding layer between said window layer and said lip-forming layer; and an adhesive bead bonding said window layer to said lip-forming layer along at least one portion of said periphery. - View Dependent Claims (19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39, 40)

41. A laminated window assembly for a device, said assembly comprising:
-
a window layer comprising a first substantially transparent material and having a periphery; a lip-forming layer larger than said window layer and comprising a second substantially transparent material, said lip-forming layer extending beyond said window layer to form a lip for engaging said device; and a substantially transparent bonding layer between said window layer and said lip-forming layer;
wherein;said lip layer has at least one hole therein adjacent said window layer for strain relief, to reduce peeling forces that reach said substantially transparent bonding layer when said lip is flexed. - View Dependent Claims (42, 43, 44)
