1. A touch control method applied to a touch device, the touch device comprising a plurality of touch electrodes and being pre-stored with a first touch mode and a second touch mode different from the first touch mode, the touch control method comprising:
step S1, sending a scanning signal to the plurality of touch electrodes if the touch device is in the first touch mode, the scanning signal is a multi-frequency scanning signal;
step S2, acquiring touch data according to the multi-frequency scanning signal if the touch device is in the first touch mode; and
step S3, judging whether it is a finger or water droplets that caused an initial coupling capacitance change by using a characteristic that a conductivity difference of the multi-frequency scanning signal in a finger is smaller than that in water droplets, and calculating a current touch position according to the touch data if the initial coupling capacitance change is caused by the finger if the touch device is in the first touch mode.
