Abstract
Embodiments of the present disclosure provide a touch panel wet state detection method and a capacitive touch apparatus. The method includes: acquiring reference feature data obtained by statistical counting of sample feature data output by a coupling capacitor when a medium between electrodes of each coupling capacitor in a capacitor array network is air; and acquiring real-time feature data output by the coupling capacitor in the capacitor array network, and determining, according to the real-time feature data output by the coupling capacitor and the reference feature data, whether the coupling capacitor is in a wet state. According to embodiments of the present disclosure, when a touch panel of a terminal is in a wet state, the touch functions can be selectively adjusted, or a part of power supplies in the circuit may be closed.
