Touch module

A force touch judgement method is applied to a force touch pad with two force sensors. Firstly, a force touch operation corresponding to a real force value is performed on a force touch position. Then, a first sensing signal value and a second sensing signal value corresponding to the force touch operation are respectively generated by the two force sensors. Then, the first sensing signal value and the second sensing signal value are added as a total sensing signal value. A calibration force value corresponding to the force touch position is obtained. A first calibration signal value and a second calibration signal value corresponding to the force touch position are added as a total calibration signal value. A ratio of the total sensing signal value to the total calibration signal value is equal to a ratio of the real force value to the calibration force value.
