Micro light-emitting diode detection system and detection method

A micro light-emitting diode detection system, comprising:

• a carrier module movable between a first position and a second position, a plurality of micro light-emitting diodes to be detected being placed on the carrier module;
• a first light generating module configured to send, when the carrier module is at the first position, a first light signal to the 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;
• a charge-coupled device camera configured to acquire the second light signals, and obtain, based on the second light signals, an image data frame;
• a second light generating module configured to send, when the carrier module is at the second position, a third light signal to the plurality of micro light-emitting diodes to be detected, such that the plurality of micro light-emitting diodes to be detected generate fourth light signals;
• a hyperspectral camera configured to acquire the fourth light signals, and obtain, based on the fourth light signals, a spectral imaging frame including spectral data of each of the plurality of micro light-emitting diodes to be detected, wherein a spatial resolution of the hyperspectral camera is less than or close to a size of the micro light-emitting diode to be detected;
• and
• a control module connected to both the charge-coupled device camera and the hyperspectral camera, and configured to:
• send, after receiving the image data frame, a control instruction to the carrier module, such that the carrier module moves from the first position to the second position;
• and
• determine, based on the image data frame and the spectral imaging frame, a defective micro light-emitting diode from the plurality of micro light-emitting diodes to be detected and the position information of the defective micro light-emitting diode.
