Claim 15:
16. A method of transferring at least one micro LED to a pixel array panel comprising a plurality of pixel regions, the method comprising:
transferring a first micro LED to a first pixel region from among the plurality of pixel regions; and
transferring a second micro LED to a second pixel region from among the plurality of pixel regions,
wherein the first micro LED and the second micro LED are transferred by spraying using an inkjet method,
wherein the transferring of the first micro LED to the first pixel region comprises:
transferring a plurality of first micro LEDs to the first pixel region, and

wherein the transferring of the plurality of first micro LEDs to the first pixel region comprises:
transferring a first group of first micro LEDs from among the plurality of first micro LEDs to a first sub-pixel region of the first pixel region using a first inkjet head;
transferring a second group of first micro LEDs from among the plurality of first micro LEDs to a second sub-pixel region of the first pixel region using a second inkjet head; and
transferring a third group of first micro LEDs from among the plurality of first micro LEDs to a third sub-pixel region of the first pixel region using a third inkjet head.
