Abstract: An LED display device array includes a substrate, at least two display units disposed on the upper surface of the substrate, and pin assemblies disposed on the lower surface of the substrate and in one-to-one correspondence with the at least two display units, a cutting line is disposed on the substrate between any two adjacent pin assemblies. Each of the pin assemblies includes at least two pins, and the at least two pins are a first pin and a second pin separately. A first pin in a pin assembly is misaligned with a second pin in an adjacent pin assembly, and the first pin and the second pin are connected to each other by a connecting wire. The connecting wire has a linear connecting segment, and the connecting segment of the connecting wire intersects with the cutting line and is perpendicular to the cutting line.

Abstract: A display module includes a substrate, m rows and n columns of pad sets, m*n sets of light emitting chip sets and multiple pins. The substrate includes a first surface and a second surface disposed opposite to each other. Each set of pad sets among the m rows and n columns of pad sets includes three pairs of pads, and first pads in the each set of pad sets are electrically connected. In a same set of light emitting chips, each of first electrodes of the light emitting chips is connected to a respective one of first pads of one set of pad sets among the m rows and n columns of pad sets, and each of second electrodes of the light emitting chips is connected to a respective one of second pads of a same set of pad sets.
