Touch and hover sensing with conductive polarizer

A method of manufacturing a touch sensitive display device, the method comprising:

• positioning an anisotropic conductive film material between a contact region of a flexible printed circuit board and a portion of a conductive polarizer, the contact region of the printed circuit board comprising a plurality of electrical contacts;
• applying one or more of pressure and heat to activate the anisotropic conductive film material between the electrical contacts on the flexible printed circuit board and corresponding regions of the conductive polarizer to electrically connect the electrical contacts to the corresponding regions of the conductive polarizer, thereby defining electrode regions on the conductive polarizer based upon geometries of the electrical contacts;
• and
• incorporating the conductive polarizer into the touch sensitive display device at a location closer to a touch surface than a display of the touch sensitive display device.

A touch sensitive display device, comprising:

• a touch surface;
• a display comprising
• a thin film transistor layer and
• a color filter structure comprising a color filter layer and a color filter support layer;
• a wire grid polarizer coupled to the color filter support structure, the wire grid polarizer comprising a plurality of conductive polarizing elements;
• a touch sensing driver circuit electrically connected to one of the thin film transistor layer and the conductive polarizer;
• and
• a touch sensing receiver circuit electrically connected to another of the thin film transistor layer and the conductive polarizer.
