Abstract:
A system and method for reducing interference caused by a near field communication antenna that is in close proximity of a touch sensor that the near field communication antenna will cause electromagnetic interference with operation of the touch sensor when the near field communication antenna is transmitting, wherein specific electrodes of the touch sensor are grounded when the near field communication antenna is actively transmitting a signal, thereby enabling the touch sensor to continue operating at the same time as the near field communication antenna.
