Forming a shield around a display for improved receiver radiated sensitivity

A portable radio, comprising:

• a housing having a display module, the display module generating radio frequency (RF) noise greater than a receiver noise floor within a very high frequency (VHF) radio band;
• a controller and a VHF narrowband transceiver operating within the housing;
• an external VHF antenna operatively coupled to the VHF narrowband transceiver, the VHF antenna being susceptible to interference from the RF noise that is greater than the receiver noise floor;
• the display module comprising:
• a liquid crystal display (LCD) having a front glass surface, wherein at least a portion of the front glass surface is viewable on the housing;
• an indium tin oxide (ITO) layer disposed on the front glass surface;
• a top polarizer layer disposed on the ITO layer, the top polarizer being retracted to form an exposed perimeter portion of the ITO layer;
• a display driver coupled to a rear glass surface of the LCD;
• a metal bezel tray within which the LCD is seated, the metal bezel tray including a top opening and being formed of four metal sidewalls, and a bottom metal surface, the metal bezel tray having a side opening in one of the sidewalls;
• a flex circuit coupled to the display driver, the flex circuit having a flex ground point, the flex ground point being coupled to a radio chassis ground of the portable radio;
• and
• a conductive adhesive tape adhered to the exposed perimeter portion of the ITO layer, the conductive adhesive tape covering all sides of the display driver, the conductive adhesive tape having a conductive tab extending therefrom, the conductive tab wrapping across the side opening of the metal bezel and adhering to the bottom metal surface of the metal bezel, the conductive tab providing a first gap and a second gap, the flex circuit protruding through the first gap to mate with the bottom metal surface of the metal bezel, the ITO layer being grounded through the conductive adhesive tape;
• wherein the conductive adhesive tape forms a ground (GND) shield around the ITO layer, the display driver, and the flex circuit.
