Abstract: A display module includes a substrate; light emitting diodes, first connection pads, second connection pads, and side wirings. The light emitting diodes are arranged on one surface of the substrate. The first connection pads are formed on the one surface of the substrate. The second connection pads are formed on an opposite surface of the one surface. The side wirings are formed on each of a first edge of the substrate and a second edge of the substrate that is adjacent to the first edge. The side wirings electrically couple the first connection pads on the one surface of the substrate with respective ones of the second connection pads on the opposite surface.

Abstract: A display module is provided. The display module includes: a substrate; a thin film transistor (TFT) layer formed on one surface of the substrate; and a plurality of micro LEDs disposed on the TFT layer. The plurality of micro LEDs are transferred from a transfer substrate to the TFT layer by a laser beam radiated to the transfer substrate through openings of a mask. The openings correspond to regions in which the respective micro LEDs of the transfer substrate are arranged and the openings correspond to a width, a length, or a unit area of each of the micro LEDs.
