Abstract
Embodiments of the present invention enable near field communication (NFC) through a touch display. Some embodiments include specialized touch displays with lower electromagnetic dissipation factors than standard touch displays. Some embodiments include methods and devices for detecting the activation or deactivation of NFC communication using the touch display and adapting the touch display to that activation or deactivation. Disclosed techniques for adapting the touch display include optimizing the behavior of the touch display for operation in the face of electromagnetic interference when NFC is activated and conducting a partial recalibration of the touch display when NFC is deactivated.
