Abstract

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.

Claims

1. A device housing comprising:

a transparent lens comprising;

a front surface;

a rear surface; and

a stepped flange along at least a portion of the lens perimeter;

the device housing being made by a process comprising;

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;

wherein;

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.

2. The device housing of claim 1, the process for making the housing further comprising:

applying optically clear light curable resin on the transparent lens rear surface on both sides of the transition line;

placing a display module on the resin; and

optically curing all of the resin using only a front optical source and a rear optical source.
