User interface substrate for handset device

Abstract

A substrate ( 56 ) for a handset device ( 10 ) includes a keypad contact array ( 108 ) on the substrate ( 56 ) and a display electrode pattern ( 604 ) on the substrate ( 56 ). In addition, in one example, the substrate ( 56 ) for a handset device ( 10 ) may include a first surface and a second surface. A keypad contact array ( 108 ) and a display electrode pattern ( 604 ) may be included on the first surface ( 96 ) of the substrate ( 56 ). A display ( 52 ) may be operatively coupled to the display electrode pattern ( 604 ). A portion of the substrate ( 56 ) may define at least a portion of an audio port ( 274 ).

1 . A substrate for a handset device comprising:
 a keypad contact array on the substrate; and   a display electrode pattern on the substrate.   
     
     
         2 . The substrate of  claim 1  further comprising a first surface and an opposing second surface wherein the keypad contact array and the display electrode pattern are both on the first surface. 
     
     
         3 . The substrate of  claim 1  wherein the keypad contact array and the display electrode pattern comprise a conductive material. 
     
     
         4 . The substrate of  claim 1  further comprising a connector operatively coupled to the substrate. 
     
     
         5 . The substrate of  claim 1  further comprising a plurality of interconnect electrical contact pads on the second surface substrate. 
     
     
         6 . The substrate of  claim 1  wherein a portion of the substrate defines at least a portion of an audio port. 
     
     
         7 . A substrate for a handset device comprising:
 a first surface and a second surface;   a keypad contact array on the first surface of the substrate wherein a portion of the substrate defines at least a portion of an audio port;   a display electrode pattern on the first surface of the substrate; and   a display operatively coupled to the display electrode pattern.   
     
     
         8 . The substrate of  claim 7  wherein the display is configured to at least partly surround the audio port portion on the substrate. 
     
     
         9 . The substrate of  claim 8  wherein the display is an electrophoretic display. 
     
     
         10 . The substrate of  claim 8  further comprising a connector operatively coupled to the second surface of the substrate and a plurality of electrical contact pads on the second surface. 
     
     
         11 . The substrate of  claim 8  further comprising at least one integrated circuit operatively coupled to the bottom surface of the substrate.
