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.

Abstract: The present disclosure provides a micro light emitting diode display panel, a method for fabricating the same, and a display device comprising the same. The micro light emitting diode display panel includes an active layer, a gate insulating layer, a gate electrode, a source electrode, a drain electrode, a pixel electrode, a micro light emitting diode, and a gate insulating layer covering the active layer, the gate insulating layer, the gate electrode, the source electrode, and the drain electrode. The light shielding layer blocks light emitted by the micro light emitting diode from being incident on the thin film transistor, thereby reducing influence of the light emitted by the micro light emitting diode light on the thin film transistor.
