LED display is divided into graphic display and video display, which are composed of LED matrix block. The graphic display screen can display Chinese characters, English text and graphics synchronously with the computer. The video display screen is controlled by a microcomputer, with pictures and pictures and images in high quality. It can broadcast all kinds of information in a real-time, synchronous and clear way. It can also display 2d and 3d animation, video, TV, VCD programs and live scene. LED display screen displays bright colors, strong three-dimensional sense, static as oil painting, moving as film, widely used in stations, docks, airports, shopping malls, hospitals, hotels, Banks, securities markets, construction markets, auction houses, industrial enterprise management and other public places.
