Assignee: PLAYNITRIDE DISPLAY CO., LTD.
Field: Semiconductors (Electrical engineering)
Classification: CPC G  H | IPC G  H

Claim 0:
1. A micro light emitting diode inspection and repairing method, comprising:
providing micro light emitting diode inspection and repairing equipment, comprising a carrying stage, an optical inspection module and an injection device, wherein the optical inspection module is arranged corresponding to the carrying stage to capture image information and obtain a position coordinate from the image information, the injection device comprises a tube and a nozzle connected to the tube, the tube comprises a first portion and a second portion connected to first portion, and an extending direction of the first portion is different from an extending direction of the second portion;
placing an object under test on the carrying stage of the micro light emitting diode inspection and repairing equipment, the object under test comprising a plurality of micro light emitting diodes;
performing an optical inspection on the micro light emitting diodes on the object under test with the optical inspection module to verify whether the object under test has at least one defect;
acquiring the position coordinate of the defect by using the optical inspection module after the defect is verified; and
removing the defect, wherein the injection device moves to the target position of the carrying stage corresponding to the position coordinate of the defect, and an extension axis of the second portion passes through the target position so that a fluid flows to the defect after passing through the tube and the nozzle to remove the defect from the object under test.
