Claim 0:
1. A touch sensing method for a touch panel having a plurality of sensing electrodes, the touch sensing method comprising:
(A) entering a first touch sensing process, wherein the first touch sensing processing comprises:
(a1) performing a non-water mode; and
(a2) determining whether there is water on the touch panel, comprising:
(i) combining the plurality of sensing electrodes in a first direction to form a plurality of first sensing regions, wherein the plurality of sensing electrodes are driven by a first driving signal;
(ii) sensing, by a plurality of sensing circuits, the plurality of first sensing regions to output a plurality of first combined sensing signals representing sensing results of the plurality of first sensing regions, respectively; and
(iii) determining that water is on the touch panel when the plurality of first combined sensing signals does not change; and

(B) entering a second touch sensing process when determining that the water is on the touch panel in the first touch sensing process, wherein the second touch sensing process comprises:
(b1) performing a water mode, wherein at least part of the plurality of sensing electrodes are driven synchronously in the water mode; and
(b2) entering the first touch sensing process to perform the non-water mode when determining that the water has been removed from the touch panel.
