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.
