Claim 10:
11. The device according to claim 10, wherein the defect detecting unit comprises a signal comparison unit and a processing unit;
the signal comparison unit is configured to obtain the detection signal from the signal receiving unit, obtain a first auxiliary signal and a second auxiliary signal from the two auxiliary receiving units, and determine an abnormal wave band based on a change of a waveform of the detection signal; and, respectively determine a first auxiliary wave band and a second auxiliary wave band in waveforms of the first auxiliary signal and the second auxiliary signal based on a detection time corresponding to the abnormal wave band;
the processing unit is configured to determine a touch unit which has a defect in the metal meshes based on a detection position of the signal transceiving component at a time corresponding to the abnormal wave band, and determine whether an amplitude of the abnormal wave band is greater than an average amplitude of multiple adjacent wave bands;
if it is determined that the amplitude of the abnormal wave band is greater than the average amplitude of the multiple adjacent wave bands, then it is determined whether an amplitude of the first auxiliary wave band or an amplitude of the second auxiliary wave band is greater than 0; if yes, it is determined that a defect type is that a touch unit corresponding to the detection position has a short-circuit defect with an adjacent channel; if not, it is determined that the defect type is that the touch unit corresponding to the detection position has a residual defect; and
if it is determined that the amplitude of the abnormal wave band is less than the average amplitude of the multiple adjacent wave bands, then it is determined whether the amplitude of the abnormal wave band is 0; if it is determined that the amplitude of the abnormal wave band is 0, then it is determined that the defect type is that there is a main path disconnection defect in the touch unit corresponding to the detection position; if it is determined that the amplitude of the abnormal wave band is not 0, then it is determined that the defect type is that there is a branch path disconnection defect in the touch unit corresponding to the detection position.
