Claim 4:
5. The touch sensing method of claim 4, wherein (a2) determining whether there is water on the touch panel further comprises:
(iv) combining the plurality of sensing electrodes in a second direction to form a plurality of second sensing regions, wherein the plurality of sensing electrodes are driven by a second driving signal;
(v) sensing, by the plurality of sensing circuits, the plurality of second sensing regions to output a plurality of second combined sensing signals representing sensing results of the plurality of second sensing regions, respectively, wherein the plurality of second combined sensing signals are associated with the first type capacitance;
(vi) determining the water is on the touch panel when the plurality of second combined sensing signals does not change; and
(vii) determining a touch position when the plurality of second combined sensing signals change.
