LED display as a new media show, with the large-scale integrated circuits and the rapid development of computer technology, has been the rapid development, and it shows that the traditional media - colorful neon lights, wall-pixel control TV, four-color magnetic turn Board, compared with its high brightness, dynamic image display, and low failure, low power consumption, long service life, the contents of a variety show, display rich, high cost performance advantages, as a new generation of display media, has been widely Applies to all walks of life. In particular, with its gray-scale display of attitude for the modernization of enterprises and promote the image of the information displayed in public places has become a media show irreplaceable.

Throughout the course of the development of LED displays, and contemporary science and technology is closely related to the first piece of LED screen in 1982 in Nanjing Railway Station is built, LED materials at that time because of restrictions on brightness light-emitting only about 8mcd, together with control and Driving circuit is not mature enough to show very poor results, high failure rate. Since 1992, with the improved performance of electronic components, large-scale integrated circuits and computer technology, LED brightness and reliability of the device's rising costs continue to decline, particularly in the financial market in the securities industry's growth So that domestic LED display into the fast-growing stage, the emergence of the multi-level gray-scale LED video screen, and TV wall, rear-projection screen compared to, LED display its high-brightness, contrast, in that they can run all-weather , And other advantages, is widely used, has become the financial, securities, the station terminals, sports stadiums, the media is essential equipment. In particular, full-color interior (that is, three interior color screen) for its full color hologram, small particles, color fidelity and the merits of a future period of the development of LED screens, such as light-emitting devices become more sophisticated and sharp price cuts , Full-color indoor market is bound to be greatly favored to make up for color projection and other equipment deficiencies.
