LEDs are all solid-state cold light sources, smaller, lighter, and more sturdy, with a working voltage of only two volts, and a service life of more than ten years. According to the usual definition of light efficiency, the luminous efficiency of LEDs is not high, but because the spectrum of LEDs is almost entirely concentrated in the visible light frequency band, the efficiency can reach 80-90. It has been more than 20 years since LED display devices came out, and it was difficult to popularize before due to the use of raw materials and technological limitations. After entering the 1990s, with the continuous improvement of technology, continuous improvement of technology and development of raw materials, LED display devices have developed by leaps and bounds in terms of life and brightness indicators, and their costs have been greatly reduced. They are suitable for various places and various applications. The number of LED displays has gradually increased. Full-color LED display is one of the more widely used displays in outdoor.
