Claim 12:
13. A detection method, applied to the detection structure of claim 1 and comprising:
providing the display backplane, the detection circuit board, and the detection LED chip;
disposing the detection circuit board on the display backplane, to connect the first detection line with the first contact electrode and connect the second detection line with the second contact electrode;
outputting a drive signal via the display backplane to the first detection line and the second detection line, and applying, by a drive circuit on the display backplane, an electrical signal to the first detection line and the second detection line row by row;
determining that the contact electrode pair on the display backplane corresponding to the detection LED chip is abnormal on condition that the detection LED chip is unlighted; and
separating the detection circuit board from the display backplane, and repairing the abnormal contact electrode pair on the display backplane for mass transfer.
