Claim 0:
1. A device comprising:
a flexible display configured to display images in at least a first touch area and a second touch area, wherein the first touch area is configured to rotate with respect to the second touch area along a folding axis;
a first plurality of column electrodes integrated into the first touch area of the flexible display;
a first plurality of row electrodes integrated into the first touch area of the flexible display;
a first plurality of drive-sense circuits operable, when enabled, to drive sensor signals on the first plurality of column electrodes and the first plurality of row electrodes;
a second plurality of column electrodes integrated into the second touch area of the flexible display;
a second plurality of row electrodes integrated into the second touch area of the flexible display;
a second plurality of drive-sense circuits operable, when enabled, to drive sensor signals on the second plurality of column electrodes and the second plurality of row electrodes; and
a processing module coupled to the first plurality of drive-sense circuits and the second plurality of drive-sense circuits, the processing module configured to:
sense, based on the sensor signals, an electrical characteristic of at least one row electrode and at least one column electrode of the first touch area or the second touch area; and
determine, based on the electrical characteristic, a proximal touch to at least one of the first touch area or the second touch area.
