The heart of the LED is a semiconductor chip. One end of the chip is attached to a bracket, one end is the negative electrode, and the other end is connected to the positive pole of the power supply, so that the entire chip is encapsulated by the epoxy resin.

The English -emitting diode is referred to as LED. In your life, you can see a variety of color glowing diodes, some of which are green, some are red, some are blue light, dazzling, and some invisible infrared and ultraviolet light. So, what determines the color of the light -emitting diodes? When a electrons jump from the guide zone to the price zone, it will radiate a photon. ), So the semiconductor forbidden bandwidth basically determines the color of the diodes.

The LED full -color display is about the light -emitting diode of many RGB three colors. Each pixel combination has an RGB diode, which shows the full color picture of different colors by the lighting of each group of pixel lamps. At present, outdoor malls are still the main market for LED display. According to industry data, LED outdoor display occupies 60%of the market, and it will inevitably develop in the future.
