Claim 0:
1. A touch panel system comprising:
a capacitive touch panel; and
a controller configured to control the capacitive touch panel,
wherein the capacitive touch panel includes a first substrate, a second substrate, a dielectric layer located between the first substrate and the second substrate, a plurality of drive electrodes located on the first substrate, a plurality of floating island electrodes located on the first substrate, a plurality of position detection electrodes located on the second substrate, a plurality of pressure detection electrodes located on the second substrate, and a plurality of heat detection electrodes located on the second substrate, wherein:
each of the plurality of heat detection electrodes is adjacent to one of the plurality of pressure detection electrodes,
each of the plurality of drive electrodes overlaps at least part of a corresponding one of the plurality of heat detection electrodes and at least part of a corresponding one of the plurality of pressure detection electrodes,
each of the plurality of floating island electrodes overlaps at least part of a corresponding one of the plurality of position detection electrodes in a plan view, and
the controller provides a drive signal to the plurality of drive electrodes and the plurality of heat detection electrodes and corrects a pressure detection signal obtained from each of the plurality of pressure detection electrodes by using a heat detection signal obtained from a change in a coupling capacitance between a heat detection electrode adjacent to a pressure detection electrode and the pressure detection electrode.
