INJECTION MOLDING OF TOUCH SURFACE
First Claim
1. A method comprising:
- positioning a touch sensor inside a mold;
injecting a moldable material into the mold around the positioned touch sensor; and
molding the injected material to encapsulate the touch sensor at a substantially uniform distance from a touchable surface of the molded material.

Abstract
Injection molding for a touch surface of a touch sensitive device is disclosed. A single-shot injection molding method can include molding an injected material to encapsulate a touch sensor at a substantially uniform distance from a touch surface of the molded material. A double-shot injection molding method can include molding a first shot of an injected material to contact a portion of a touch sensor and molding a second shot of an injected material to encapsulate at least the remaining portions of the touch sensor to form a touch surface at a substantially uniform distance from the touch sensor. Another molding method can include molding a coating on a touch sensor to having a substantially uniform thickness. The injection molded material can provide a substantially uniform capacitive dielectric for the device. The injection molded touch surface can be incorporated into an electronic mouse, a mobile telephone, a digital media player, or a computer.
