Claim 9:
10. The detection method for impedance of the display device according to claim 9, wherein the first detection part comprises a first sub-detection part, and the second detection part comprises a second sub-detection part;
the step of detecting the first detection part and the second detection part to detect the impedance comprises:
disposing the first sub-detection part and the second sub-detection part on the circuit board, connecting the first sub-detection part to the conducting pins, and connecting the second sub-detection part to the first sub-test pin; and
correspondingly connecting two detection terminals of a detecting device to the first sub-detection part and the second sub-detection part to detect an impedance of a bonding region of the circuit board.
