Since the 1980s, with the public more information, the establishment of high-performance, low-cost large-scale information media has been of concern to engineers and technicians. According to the application of the different requirements of the show, as well as the performance of the display system cost requirements of different people can choose to display different media. Hu Neiwai to take into account the large-screen display for the media shows that the color, brightness, video effects, reliability, performance requirements, such as life expectancy compared with harsh.

It requires System show to show close to true color images of natural color and high brightness of the display, either during the day or at night, sunny or cloudy, so that the audience will be able to clearly see their content, and can According to the external natural light intensity changes are automatically displayed on their broadcast video programming, high reliability and cost-effective, easy to maintain. Many of the above factors, engineers and technicians through the magnetic replica of pixels vacuum tubes, TV wall, LED screen comparison and found that as the LED display pixel can be very good to meet these requirements, is a good display Hu Neiwai Media.

At the same time, along with the development of science and technology, today's semiconductor light-emitting diode performance reached a new level of the photoelectric conversion efficiency 10cd / w above, in particular, ultra-bright blue LED devices, LED devices made of the spectrum of coverage Natural light.

As a result, large-scale use of LED device manufacturing flat-panel display system LED devices become an important field of application, which promoted the development of large-scale display system and the formation of an industry. Using LED display device composed of the most prominent feature of its manufacturing area is not restricted to the order of tens to hundreds of square meters, used in a variety of indoor and outdoor public display text, graphics, video, animation, video, etc. A variety of information, hundreds of people stood watching at the same time, a strong advertising and rendering power, the city's social activities with strong play up the atmosphere, landscape and rich people's living environment.
