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: The disclosure provides a light-emitting device and a displayer. Herein, the light-emitting device includes a substrate, a light-emitting chip, a first light-transmitting layer, a second light-transmitting layer and a nano coating. The light transmittance of the second light-transmitting layer is greater than the light transmittance of the first light-transmitting layer. A reference surface corresponding to the light-emitting chip is arranged above the substrate, and the reference surface is higher than the bottom surface of the light-emitting chip and not higher than the top surface of the light-emitting chip. The first light-transmitting layer covers the surface of the light-emitting chip below the reference surface, and the second light-transmitting layer covers the surface of the light-emitting chip above the reference surface. The nano coating covers the outer surface of the first light-transmitting layer, the outer surface of the second light-transmitting layer and the side surface of the substrate.
