Electronic device having a display and method for manufacture

摘要

A method of making a device housing involves providing a transparent lens with a front surface and a rear surface, and a stepped flange along at least a portion of the lens perimeter. The method includes injecting plastic onto the transparent lens perimeter, including the stepped flange, the plastic forming a plastic feature that has a front surface that is tangent to the front surface of the transparent lens, a rear surface that is tangent to the rear surface of the transparent lens, and that extends outward from the sides of the transparent lens away from a device width center line. The plastic feature is molded to the rear surface of the transparent lens at at least one of two ends of the device housing, and the plastic encapsulates a stepped middle surface of the transparent lens flange. A device housing that is made by this method is also included.

1. A method of making a device housing, the method comprising:
providing a transparent lens with a front surface and a rear surface, and a stepped flange along at least a portion of the lens perimeter; applying an oleophobic coating to the front surface of the transparent lens; injecting plastic onto the transparent lens perimeter, including the stepped flange, the plastic forming a plastic feature that has a front surface that is tangent to the front surface of the transparent lens, a rear surface that is tangent to the rear surface of the transparent lens, and that extends outward from the sides of the transparent lens away from a device width center line; applying optically clear light curable resin on the rear surface of the transparent lens; placing a display module on the resin; and optically curing the resin with at least one optical source;wherein:
a first boundary between the front surface of the transparent lens and the plastic feature is closer to a center line of the transparent lens than a second boundary between a back surface of the transparent lens and the plastic feature, the plastic feature is molded to the rear surface of the transparent lens at at least one of two ends of the device housing; and the plastic encapsulates a stepped middle surface of the transparent lens flange.
