Abstract
A device for transferring micro light-emitting diodes includes a collection tube and an elastic port. The collection tube has a first end and a second end arranged oppositely, and a caliber of the collection tube is greater than a diameter of the micro light-emitting diodes. The elastic port is disposed at the first end, and a caliber of the elastic port is less than the diameter of the micro light-emitting diodes. The micro light-emitting diodes are pressed into the collection tube from the elastic port. The collection tube can store the micro light-emitting diodes. The device can effectively improve transfer speed.
