Claim 27:
28. 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 second micro LED to the second pixel region comprises:
transferring a plurality of second micro LEDs to the second pixel region,

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