LED panel: LED is light emitting diode. It uses the principle of semiconductor P-N junction electroluminescence to produce red, green and blue colors. It is a semiconductor display device that was not developed in the 1960s; In the 1970s, with the development of semiconductor material synthesis technology, single crystal manufacturing technology and P-N junction formation technology, the performance of light emitting diodes in color, brightness and other aspects was improved and rapidly entered into batch and practical use; In the 1980s, LED has greatly improved its light emission wavelength range and performance, and began to form a flat panel display product, namely LED display screen. In the late 1980s, a new information display media that was rapidly developed in the world made use of dot matrix modules or pixel units composed of light emitting diodes to form an area display screen, featuring high reliability, long service life, strong environmental adaptability, high price performance ratio, low use cost, etc, In just ten years, it has rapidly grown into the mainstream product of flat panel display, and has been widely used in the field of information display.

LED display screen is divided into graphic display screen and video display screen, both of which are composed of LED matrix blocks. The graphic display screen can synchronously display Chinese characters, English text and graphics with the computer; The video display screen is controlled by a microcomputer, with pictures, texts and images. It can broadcast various information in a real-time, synchronous and clear way of information transmission. It can also display two-dimensional and three-dimensional animation, video, television, VCD programs and live scene. The LED display screen has bright colors and strong stereoscopic sense, which is as static as oil painting and as dynamic as film. It is widely used in stations, docks, airports, shopping malls, hospitals, hotels, banks, securities markets, construction markets, auction houses, industrial enterprise management and other public places.
