    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 are a LED display unit group and a display panel. The LED display unit group includes a circuit board and pixel units. The circuit board includes N metal wiring layers stacked in sequence and an insulating plate disposed between adjacent metal wiring layers, and the N metal wiring layers are electrically connected through conductive vias on the insulating plate. The pixel units are arranged in an array of m rows and n columns and disposed on the circuit board. Each pixel unit includes at least two LED light-emitting chips with different emitted colors, each LED light-emitting chip is fixed on a first metal wiring layer. The first metal wiring layer includes m common A-electrode pads, A-electrode pads, and B-electrode pads. All the A-electrode pads corresponding to each row of pixel units are integrally formed with and electrically connected to one corresponding common A-electrode pad.
