China's LED semiconductor lighting industry started in the early 1990s and has always maintained rapid development. In 2008, the number of members of the China Light Association LED Display Application Branch was 204. There are more than 300-400 professional production units in the country, and more than 1000 manufacturers of LED display applications are engaged in LED display applications including sales. The production, supporting services and other enterprises are estimated to be no less than 3,000.
The number of employees in the display application industry with LED display as the leading product is around 30,000. In 2008, the national output value was nearly 10 billion yuan. According to industry associations, manufacturers account for 6% of the Northeast, 17% of Southwest China and Northwest China, 16% of North China, 41% of East China, and 20% of South China. From the industrial layout, the LED display industry is mainly concentrated in East China and South China. The total size of products in these two regions accounts for more than 60% of the country. Due to the rapid development of China's economy and the hosting of the Olympic Games, the LED display industry has achieved good development opportunities. The industry as a whole has experienced significant growth compared to previous years.
LED technology and computer technology and electronic technology have advanced by leaps and bounds, and LED display technology has also shown rapid development. The color of the display screen is popular from single and double color to full color. The display content is converted from text picture to video real-time display. The display control technology develops from single screen to network, and the display shape develops from plane to face. The domestic advanced level of display and the quality of the international brand level are similar, and most of the technical indicators of domestic mainstream products are close to international brand products. However, the display MTBF, refresh rate, brightness uniformity, shell protection level, safety requirements, EMC, product quality certification, especially the product process and international brand products have a certain gap.
In 2009, domestic LED application manufacturers are in a critical period. On the one hand, with the global energy crisis and the worsening of the environment, governments have greatly supported the LED technology as the fourth-generation light source, coupled with the rapid development of LED technology and the efforts of LED manufacturers. The trend of LED lighting replacing traditional CFFL and energy-saving lamps has become a consensus. LED manufacturers will face a very large market. On the other hand, many testing standards in the domestic LED industry have not been established, and the entire market is highly competitive and disorderly. LED giants, such as Cree, Philips, Osram, etc., are targeting the Chinese LED market and actively marketing. There are signs that in the next 3-5 years, the era of LED lighting will truly replace traditional lighting is coming. At that time, the market conditions for LEDs entering thousands of households will be basically improved, such as macro policies, industry testing standards, business models, Industry chain maturity, performance indicators, production scale, etc. At that time, the LED industry will certainly undergo a massive reshuffle and market restructuring campaign. For domestic LED application manufacturers, the primary issue that should be considered at present is that after 3-5 years, when the LED industry is completely market-oriented and facing reshuffle, how to compete fiercely with domestic manufacturers and the suppression of foreign giants inside and outside Survival under double pressure, if it survives, what role will continue to fight in the market.
At present, LED industry investment is a very hot key project, and countries around the world pay more attention to LED R&D and production. The LED industry has developed so far and has experienced many ups and downs. Looking at the development trend of the LED industry, it has been unquestionable that it has achieved remarkable results. China has great advantages in developing the LED industry, especially LED display manufacturers. First of all, China has a large market demand. Second, from a resource perspective, China has abundant non-ferrous metal resources. Then there is the semiconductor lighting industry is a technology-intensive and labor-intensive industry, which is more suitable for China's national conditions. If China can adhere to independent innovation in epitaxy, chip preparation and independent packaging technology, it is entirely possible to realize the leap-forward development of China's semiconductor lighting industry. It is estimated that the output value of China's entire LED industry will exceed 100 billion yuan in 2010. China is the world's largest producer of lighting sources and lamps, but mainly low-end products, accounting for only 18% of the world market, big but not strong. It is of great significance to develop semiconductor lighting and enhance the international competitiveness of the industry. At present, China's LED product technology innovation and application development capabilities are gradually improving, device reliability research position is more prominent, test methods and standards are gradually getting closer, all of which marks that China's LED industry has entered a new stage of development. . After more than 30 years of development, China's LED industry has initially formed a relatively complete industrial chain including the production of epitaxial wafers, the preparation and packaging of chips, and the application of LED products.
