Abstract: A LED display structure and its display module thereof are provided. The LED display module includes a LED array, a substrate disposed below the LED array, and at least one trace configuration layer, which is disposed below the LED array and adjacent to the substrate. The at least one trace configuration layer includes a plurality of wires, and a distribution density of the wires varies according to a distance between the wires and the LED array. When the distance increases, the distribution density of the wires is denser. Otherwise, the distribution density is sparse when the wires are closer to the LED array. In view of the simulation experimental analyses of the present invention, it is believed that at least 30% of the stray light ratio can be reduced so as to enhance the LED display structure with better transparency and image quality.
