Abstract
A method of manufacturing a micro light emitting diode (LED) display and a transfer apparatus are provided. The method of manufacturing a micro LED display includes: identifying a repairing micro LED, from among a plurality of second micro LEDs, on a second substrate based on a first position of a defective micro LED, from among a plurality of first micro LEDs, on a first substrate; removing the defective micro LED from the first substrate; matching the first position on the first substrate from which the defective micro LED has been removed to a second position of the repairing micro LED on the second substrate; and transferring the repairing micro LED from the second position on the second substrate to the first position on the first substrate from which the defective micro LED has been removed, by using a laser transfer method.
