A touch sensitive processing method for detecting whether a touch panel is partially submerged in conductive liquid, wherein the touch panel comprises multiple parallel first electrodes and multiple parallel second electrodes, comprising:
- detecting a liquid surface line and a covered area of the touch panel, below the liquid surface line, which is covered by the conductive liquid;
- detecting first touching or approximating event in the covered area;
- when zero or three first touching or approximating events are detected, reporting no first touching or approximating event to a host;
- and
- when one first touching or approximating event is detected, reporting the first touching or approximating event to the host.
