Claim 11:
12. The detection method for impedance of the display device according to claim 11, wherein the first detection part comprises a third sub-detection part, and the second detection part comprises a fourth sub-detection part;
the step of detecting the first detection part and the second detection part to detect the impedance comprises:
disposing the third sub-detection part and the fourth sub-detection part on the circuit board, connecting the third sub-detection part to the conducting pins, and connecting the fourth sub-detection part to the second sub-test pin;
correspondingly connecting two detection terminals of the detecting device to the third sub-detection part and the fourth sub-detection part to detect a total impedance of a bonding region of the circuit board and a bonding region of the display panel; and
according to the impedance of the bonding region of the circuit board and the total impedance, obtaining an impedance of the bonding region of the display panel.
