LED display industry analysis and the prospects for the future

led the rise, lighting reform wave arrival
the Chinese led initial rapid growth is was officially launched in 2003, the national semiconductor lighting project of large-scale urban traffic signal lamp replacement began. In recent years, the government's preferential policies to promote the rise of the LED industry, Shenzhen City, just a few years time from more than 700 led rapid development to more than 2000 manufacturers. In the & ldquo; National Semiconductor Lighting Project & rdquo; push, China's LED industry has initially formed a including LED chip preparation, LED epitaxial wafer production, LED chip encapsulation and LED application products, complete industrial chain. Shenzhen, Nanjing and other major cities have also responded to the call, the construction of the LED Industrial Park and led industrial base, and issued the relevant development planning. 2005 car LED lighting and LED decorative lamps with the growth of LED second development in this year, the domestic semiconductor lighting LED market sales reached more than 1 billion, an increase of 49% over 2004. In the 2008 financial crisis, the international demand for a substantial reduction in the LED industry to look at the domestic market. Favorable policies followed by the Ministry of science and technology in December 2008 proposed to carry out “ Ten City million ” project. In March 16th this year, the Ministry of science and Technology Department of the original 10 cities changed to 21. These cities will receive central subsidies in the future, in the public space, such as roads, tunnels, parking and gas stations and other places, the installation of LED lighting.
second, LED industry pattern and led the advantages and the disadvantages of the
1996 years I country begins to carry out the & ldquo; green lighting engineering & rdquo;, Xiamen, Shanghai, Nanchang, Shenzhen and so on have formed semiconductor lighting industrial base. The Yangtze River Delta, the Pearl River Delta, the Yangtze River Delta and the northern region has become the gathering place for the development of China's LED industry. Now I have a led to form a complete industrial chain, and gathered to form a large area of 7, 4 bases of the industrial structure. Now engaged in the number of LED industry to more than 20, more than 50 thousand research institutions, more than 4000 enterprises; and the emergence of a number of innovative, advanced technology companies. Under the pull of huge domestic demand, LED industry outlook is bright.
three, LED display industry is facing the risk of LED in technology
belong to the high-tech industry, production technology and product is not mature. Whether the industry can continue to improve the production of LED technology for the industry is important. Once the technology behind the international level is too much, it will lose a lot of market share and even a vicious circle of loss. Domestic have yet to develop LED lighting standards, only to follow the traditional sodium lamp detection method to detect LED lamp, but the two are the essential difference. In addition, the country's application standards vary, resulting in cross regional development of enterprises encountered a lot of resistance. Risk of industrial transfer. Taiwan has about 80% of the package transferred to the mainland, the new single upstream and epitaxial films are very few. To improve the industrial structure, and Taiwan enterprises competition is inevitable, at present, enterprises are still at a disadvantage. The size of domestic LED enterprises is small, scattered throughout the industrial resources, there is no scale, resulting in a single firm from abroad, the high price of imported chips, low bargaining power of the situation, so that the high cost. The current industry core patent lack, especially the heat balance problem of the key of white light, high power LED lamp, lasting efficient phosphor patent has been monopoly of Europe, America, Japan, suppress the development of industry of our country. Affected by the global financial crisis, the world's support for the LED is likely to weaken, the popularity of LED in western countries and we may be below the expected level. There is still a large gap in the LED epitaxial wafer and chip production, with the international advanced level compared domestic chip luminance, luminous efficiency, antistatic ability, the ability of anti leakage and quality control standards, now China's core chip need imported from the United States, prices high, cost pressure is too big.
