The utility model discloses a display module and an LED display screen, and belongs to the technical field of LED display screens. The display module comprises a PCB, a plurality of driving ICs, a BTsubstrate with a circuit and a plurality of LED chips. Wherein the PCB comprises a bottom surface and a top surface which are opposite to each other, the plurality of driving ICs are fixed on the bottom surface, the BT substrate comprises an upper surface and a lower surface which are opposite to each other, the lower surface of the BT substrate and the top surface are fixed together, and the plurality of LED chips are assembled on the upper surface of the BT substrate. The BT substrate is higher in line precision; smaller line width and line distance can be realized; more precise circuits canbe formed on the upper surface and the lower surface; compared with the prior art, smaller and more precise LED chips can be carried, the surface line width, the line distance, the pattern precision,the green oil windowing pr
