The technology of LED display is developing more and more, and it is widely used in securities trading, finance, transportation, sports, advertising and other fields. LED display technology includes semiconductor optoelectronic technology, electronic circuit technology, integrated circuit technology, image information processing technology and information. Transmission technology, computer network technology, and technology related to electronic product manufacturing and electronic product installation engineering.
Since the 1980s, while the scale has developed rapidly, the product technology has also been innovated, and it has maintained a relatively advanced level in this field. As early as the early 1980s, the domestic LED display had mature 5-level grayscale video control technology and wireless remote control level grayscale video control technology. The wireless cluster control and multi-level group control technology are all advanced at home and abroad. The products of technical level appear in the special large-scale integrated circuits for display control, and domestic enterprises have also developed and produced them and have been put into practical application after more than ten years of development.
At present, my country's LED display industry has begun to take shape. "A group of backbone enterprises with a certain scale has been formed. At the beginning of the establishment of the LED display professional committee, there were 55 member units", which basically concentrated the representative and influential display of the country. The leading enterprise in the display industry. In early 2003, the Optoelectronic Devices Branch of the China Optics and Optoelectronics Industry Association. The LED Display Professional Committee was upgraded with the approval of the Ministry of Civil Affairs. .
In addition, with the development of computer network technology, "LED display screen is used more and more in the network environment", in the information display system composed of multimedia and various display devices, "intelligent network control" network control multi-screen technology is also In practice, the overall scale trend of the entire industry is that the overall number of companies in the industry increases year by year, and professional companies or some listed companies at home and abroad have joined in. The structure is characterized by private enterprises as the main body, and emerging companies account for the vast majority of them. The employees are relatively young, and the scale of enterprises in the industry varies. In fact, although there are many manufacturers of domestic LED display products and markets that are developing rapidly, there is still no one company to replace them.
