Publicize commodities and attract customers.2. Decorate the storefront and improve the level of enterprises.3. Lighting, innovative.4. Popularize knowledge.5. Bulletin board (announce some information).6. Fostering atmosphere.Through the display screen, we can broadcast the welcoming speech of the superior leaders and all kinds of VIPs to visit and guide, the celebration speech of all kinds of major festivals and so on.LED electronic display screen is a display mode by controlling semiconductor light-emitting diodes. It consists of tens of thousands to hundreds of thousands of pixels of semiconductor light-emitting diodes arranged evenly. It uses different materials to produce different color LED pixels to display various information such as text, graphics, images, animation, market, video, video signal and so on. At present, the most widely used are red, green and yellow. The development of blue and pure green LED has reached a practical stage.The History of LED Electronic Display ScreenIn the 1960s, a semiconductor display device was developed.In the 1970s, with the development of semiconductor material synthesis technology, single crystal manufacturing technology and P-N junction formation technology, the luminous color and brightness of light-emitting diodes (LED) have been improved and rapidly entered batch production and practicality.In the 1980s, the range and performance of LED light-emitting wavelength were greatly improved, and flat panel display products, namely LED display screen, began to be formed.In the late 1980s, a new type of information display media developed rapidly all over the world, which is composed of dot matrix module or pixel unit made up of light-emitting diodes. With the characteristics of high reliability, long service life, strong environmental adaptability, high price performance ratio and low cost, it has rapidly grown into the mainstream product of flat panel display in the past ten years. The field of information display has been widely used.
