20 Claims

1. An integrated touchscreen comprising:

a plurality of regions, each of the plurality of regions including a plurality of touch node electrodes; and

touch chiplets coupled to the plurality of touch node electrodes, wherein each of the plurality of touch node electrodes is coupled to a corresponding one of the touch chiplets;

wherein the touch chiplets are configured to simultaneously sense the plurality of touch nodes electrodes of the plurality of regions in a spectral analysis mode while the touch chiplets do not stimulate the plurality of touch node electrodes, such that noise at multiple frequencies are simultaneously sensed for each of the plurality of regions.
