Contoured capacitive touch control panel
First Claim
1. A method of manufacturing a contoured capacitive touch screen control panel comprising:
- printing control indicia on at least one of a front surface and a back surface of a flexible film;
printing conductive ink pads on a back surface of the film with each pad being aligned with respective printed control indicia;
disposing the printed film in an injection mold with the conductive pads printed on the back surface of the flexible film being in contact with a back surface of the mold so that a space remains between the front surface of the flexible film and a front surface of the mold; and
flowing a molten plastic into the space in engagement with the front surface of the film to form a control panel with the printed indicia being visible through the control panel from a face of the control panel opposite from the film molded in situ.

Abstract
A method of manufacturing a contoured capacitive touch screen control panel includes printing control indicia on at least one of a front surface and a back surface of a flexible film. The method also includes printing conductive ink pads on a back surface of the film with each pad being aligned with respective printed control indicia. The method also includes disposing the printed film in an injection mold with the conductive pads printed on the back surface of the flexible film being in contact with a back surface of the mold so that a space remains between the front surface of the flexible film and a front surface of the mold. The method then includes flowing a molten plastic into the space in engagement with the front surface of the film to form a control panel with the printed indicia being visible through the control panel from a face of the control panel opposite from the film molded in situ.
