Abstract: A display module is provided. The display module includes a substrate including a thin film transistor (TFT) layer including a plurality of TFTs, a plurality of light emitting diodes (LEDs) arranged on a front surface of the substrate, each LED corresponding to a respective TFT, and an operation driver that is connected to a rear surface of the substrate and controls an operation of the TFTs. The substrate includes a plurality of first via holes extending in a vertical direction from the front surface of the substrate to the rear surface of the substrate. The first via holes are filled with conductive materials and are distributively arranged based on at least one of the columns or rows of the plurality of LEDs. The first via holes connect the TFTs to the operation driver.
