Abstract
A method for operating an electronic device includes: having a touch sensitive display configured to be rolled into or unrolled out of a first retainment structure along a first direction. The first retainment structure includes a conductive material disposed within the first retainment structure. The method includes unrolling or rolling the touch sensitive display to an unrolled position along the first direction; determining that the touch sensitive display is detecting contact at a plurality of mutual sensing locations using a mutual sensing process; determining that the touch sensitive display is detecting contact at a plurality self-sensing locations using a self-sensing process; determining a plurality of multi-mutual sensing locations based on multi-mutual sensing values obtained from a multi-mutual sensing process; and determining the unrolled position along the first direction based on the plurality of mutual sensing locations, the plurality self-sensing locations, and the plurality of multi-mutual sensing locations.
