Abstract
A method of manufacturing a micro light emitting diode (LED) display module. The method of manufacturing a micro LED display module may include: pressing a plurality of micro LEDs disposed on a substrate to which an adhesive layer is applied, to electrically connect the plurality of micro LEDs to electrode pads of the substrate; performing testing to detect whether at least one of the plurality of micro LEDs is defective in a state in which the plurality of micro LEDs are pressurized and the adhesive layer is uncured; and based on detecting that at least one of the plurality of micro LEDs is defective, performing control to harden the adhesive layer.
