LED display is a large-scale display system integrating microelectronic technology, optoelectronic technology, computer technology and information processing technology. In the stadium, it is an information management center that integrates the scoring display, graphics, video, audio and other multimedia playback of various professional sports competitions, as well as the management of background data of athletes and sports teams. Due to the bright environment of the stadium, the visual distance and the visual angle are relatively large; therefore, the display system of the stadium is required to be able to display the information of the game in an all-round, clear, timely and accurate manner. And create a tense, warm atmosphere of the game. As the main means of game information display and game live broadcast, LED display has replaced traditional lighting and CRT display, and has become an essential game facility in modern stadiums. At the same time, in this process, all major countries attach great importance to the detection method of LED. LED display has the characteristics of strong environmental adaptability, high reliability and high cost performance. In just ten years, it has been widely used in the field of information display.
Incandescent lamps were first used for display in stadiums, and then LED displays were gradually introduced as light sources, and the display content gradually changed from the previous numbers to text, pictures and videos. Beijing's successful bid for the Olympic Games has become an opportunity for the development of the LED display industry. In LED display technology, display color, brightness and viewing angle, grayscale control technology, drive circuit and system application and detection control technology of LED display in stadiums have been continuously improved in practice and have received widespread attention. Therefore, LED displays appeared on the field of play, and now LED displays have spread all over the stadiums.
The characteristics of stadium display screens are low frequency of use and slow replacement, which will gradually saturate the demand in this market. In order to improve the level of the venue and be able to undertake more large and medium-sized competitions, it is imperative to build an LED display.
For the development of LED in China, through continuous technological innovation, technological research, and the introduction of foreign advanced equipment and key technologies, the production of LED technology has been taking a big step forward.
LED display is one of the fastest growing industries in the world today. For flat panel display products, the viewing angle is a very important indicator in the detection of the display screen. Viewing within the viewing angle range can enable all viewers to enjoy the best viewing effect. Beyond this range, the brightness will be reduced, which will affect the picture quality. Quality, the larger the viewing angle of the LED display, the more its audience, the wider the coverage area, and the smaller it is.
