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.

Abstract: Provided is a light-emitting diode (LED) display assembly. The LED display assembly includes a plurality of chips, a first carrier and a second carrier. Two opposite side surfaces of the first carrier are respectively a first mounting surface and a second mounting surface. The first mounting surface is provided with first pads, and the first pads are connected to the chips. The second mounting surface is provided with first pins, and wires in the first carrier connect the first pads to the first pins. An area of each of the first pins is larger than an area of each of the first pads. The second carrier is provided with a third mounting surface, the third mounting surface is provided with second pads whose number is the same as a number of the first pins, and the second pads are welded to the first pins in one-to-one correspondence.
