1. A detection structure, configured to detect a display backplane and comprising:
a detection circuit board comprising:
one or more first detection lines and one or more second detection lines, disposed at intervals on one side of the detection circuit board, wherein the one side faces the display backplane; and
one or more first detection electrodes and one or more second detection electrodes, disposed at intervals on another side of the detection circuit board, wherein the another side is away from the display backplane, and wherein the first detection electrode is electrically connected with the first detection line and the second detection electrode is electrically connected with the second detection line; and
one or more detection light-emitting diode (LED) chips each comprising:
a first electrode and a second electrode, wherein the first electrode is electrically connected with the first detection electrode and the second electrode is electrically connected with the second detection electrode,
wherein the first detection line is configured to be electrically connected with a first contact electrode of a contact electrode pair on the display backplane having one or more contact electrode pairs arranged in a matrix, and the second detection line is configured to be electrically connected with a second contact electrode of the contact electrode pair on the display backplane.
