A method for manufacturing a display module includes the steps of: transferring LEDs of a substrate to a first relay substrate; transferring the LEDs of the first relay substrate to a second relay substrate in a primary stretch array such that a gap between adjacent LEDs on the second relay substrate is greater than a gap between adjacent LEDs on the first relay substrate in one direction from among a row direction and a column direction; and transferring the LEDs of the second relay substrate to a target substrate in a secondary stretch array such that a gap between adjacent LEDs on the target substrate is greater than a gap between adjacent LEDs on the second relay substrate in a remaining direction from among the row direction and the column direction.

Display module and method for manufacturing display module

A light emitting diode (LED) transfer system includes an alignment apparatus configured to align a plurality of target substrates; a handling robot configured to transport the plurality of target substrates; a transfer stage configured to hold the plurality of target substrates and move the plurality of target substrates; a substrate stage configured to move a relay substrate having a plurality of LEDs with respect to the transfer stage while the plurality of LEDs are facing the transfer stage; a laser configured to emit a laser beam toward the plurality of LEDs of the relay substrate so that the plurality of LEDs are transferred from the relay substrate to the plurality of target substrates; and a processor configured to control the alignment apparatus, the handling robot, the transfer stage, the substrate stage, and the laser to transfer the plurality of LEDs of the relay substrate to the plurality of target substrates.
