1. A detection method of a three-dimensional touch module, the detection method being applied to a three-dimensional touch module comprising a control module, a two-dimensional inputting assembly comprising a first electrode being a receiving electrode layer, a second electrode being a transmitting electrode layer, and a pressure sensing assembly, the detection method comprising:
step S1: providing an input signal to the transmitting electrode layer disposed between the two-dimensional inputting assembly and the pressure sensing assembly, wherein the two-dimensional inputting assembly and the pressure sensing assembly share the transmitting electrode layer;
step S2: outputting a first output signal and transmitting the first output signal to the control module by the receiving electrode layer of the two-dimensional inputting assembly, outputting a second output signal through a third electrode, the third electrode being a conductive layer of the pressure sensing assembly contacting a pressure layer of the pressure sensing assembly, the second electrode being disposed between the first electrode and third electrode the pressure layer having a first surface and a second surface and the conductive layer being superimposed on the first surface, and transmitting the second output signal to the control module by the pressure sensing assembly, wherein the first surface faces the conductive layer and faces opposite to a cover plate of the three-dimensional touch module; and
step S3: determining a touch position according to the first output signal by the control module, and determining a pressure value according to the second output signal by the control module, wherein when the first output signal and the second output signal are output concurrently, the step S3 comprises:
step Sa: receiving, by the control module, the first output signal output by the receiving electrode layer of the two-dimensional inputting assembly to complete detection of the touch position, and receiving, by the control module, the second output signal generated by the pressure sensing assembly to complete detection of the pressure value.
