Abstract: A micro light-emitting diode detection system includes: a first light generating module configured to send a first light signal to a plurality of micro light-emitting diodes to be detected, such that the plurality of micro light-emitting diodes to be detected generate second light signals, the first light signal including a laser signal; a hyperspectral camera configured to acquire the second light signals, to obtain a spectral imaging frame including spectral data of each of the plurality of micro light-emitting diodes to be detected; and a control module connected to the hyperspectral camera, and configured to determine, based on the spectral imaging frame, a defective micro light-emitting diode from the plurality of micro light-emitting diodes to be detected.
