Touch control sensing system, electronic touch control device and touch control sensing method

The invention provides a touch control sensing system which comprises a touch control interface, at least one sensing unit and a switching unit. The sensing unit is coupled to the touch control interface. The switching unit is used for switching the touch control sensing system into a first sensing mode or a second sensing mode according to a control signal. When the touch control sensing system is in the first sensing mode, the sensing unit senses a first sensing signal and a second sensing signal of the touch control interface. On the other hand, when the touch control sensing system is in the second sensing mode, the sensing unit senses the first sensing signal according to a drive signal. The invention further provides an electronic touch control device and a touch control sensing method.
