1. An electronic device, comprising:
a housing;
display circuitry having pixels formed using an anode layer and a cathode layer;
touch sensor circuitry formed above and overlapping the display circuitry within the housing;
a shielding layer interposed between the display circuitry and the touch sensor circuitry; and
noise cancellation circuitry having an input connected to the display circuitry for receiving a noise signal from the display circuitry, wherein the noise cancellation circuitry is configured to invert the noise signal and to drive the inverted noise signal onto the shielding layer to prevent noise associated with the display circuitry from interfering with the touch sensor circuitry.
