1. A method for manufacturing a display module, the method comprising:
transporting a plurality of light emitting diodes (LEDs) of a substrate to a first relay substrate such that a first gap is between two immediately adjacent LEDs of the plurality of LEDs on the first relay substrate in one direction from among a row direction and a column direction;
transporting the plurality of LEDs of the first relay substrate to a second relay substrate in a primary stretch array such that a second gap is between two immediately adjacent LEDs of the plurality of LEDs on the second relay substrate in the one direction from among the row direction and the column direction and a third gap is between two immediately adjacent LEDs of the plurality of LEDs on the second relay substrate in the other direction from among the row direction and the column direction, the second gap is greater than the first gap; and
transporting the plurality of LEDs of the second relay substrate to a target substrate in a secondary stretch array such that a fourth gap is between two immediately adjacent LEDs of the plurality of LEDs on the target substrate in the other direction from among the row direction and the column direction, the fourth gap is greater than the third gap.
