LED advertising screen as an important carrier of communication

LED full-color display is developed from the 90s of last century, with the rapid development of semiconductor technology and electronic technology to gradually mature. In the early stage of LED, there are some problems, such as small visual angle, low brightness, low uniformity, low resolution and unstable quality. Modern LED display technology is developing towards high performance, such as wide viewing angle, high brightness, high definition, high quality, high reliability and so on.

Sports venues are one of the first places to start the application of LED advertising screen, and now the modern stadium color LED display and scoreboard has become an essential equipment. In the 2008 Beijing Olympic Games, the application of LED display can be fully reflected. In addition to each of the venues are equipped with a large LED display and the scoreboard, the opening ceremony of the innovative application of magic is also huge scrolls LED display. In recent years, indoor and outdoor LED advertising display World Plaza, the A new force suddenly rises., big city, traffic routes are important station in the establishment of advertising information to the big screen, color LED advertising display brings a broader market. The LED display is also widely used in the transportation hub, stock exchange, large-scale theatrical performances, exhibitions and other large public places; in addition to building decorative lighting and LED display mutual penetration technology, make the city become more and more bright and colorful night.

Modern color LED display is a photoelectric technology, computer technology, digital processing technology and other technologies as one of the high-tech products. It adopts high quality red, green and blue three colors of the semiconductor light emitting device (LED) composed of color light emitting pixel tube, by special large-scale and ultra large scale integrated circuit display circuit, the color television signals and computer signals by digital processing in the first few square meters to achieve large-scale display system of color image and text information display equipment thousand square meters of large screen. It is not only a huge color TV, but also a large color computer terminal, coupled with the configuration of the sound to make it a powerful multimedia information dissemination tool. Huge color screen can make thousands of people watch at the same time, with great rendering power. These characteristics make LED advertising display in the television, newspapers, magazines, radio and the Internet, such as the main media of the list, in today's new moon in the era of information technology development, is playing a more and more significant role.
