Because the magnetic field intensity change curve generated by the electromagnetic plate is known, on the basis, the motion characteristic of the display module can be calculated by combining the acquired intensity information of the electromagnetic signal received by the receiving module.

After obtaining the strength information of the electromagnetic signal received by the receiving module, step 530 is executed: and determining the motion characteristics of the display module according to the strength information of the electromagnetic signals received by the receiving module.
