Chip development to help upgrade the LED industry

After years of development, China's LED industry chain is becoming more and more perfect. But the CCID semiconductor industry research center analyst Wang Ying recently told reporters that the LED industry chain, due to the high technology and capital requirements in the upstream industry, domestic enterprises rarely involved, so the upstream industry has the characteristics of small number and scale of the enterprise. In contrast, the downstream packaging and application to business of financial and technical requirements are relatively low, coincided with the characteristics of domestic enterprises less capital, technology weak match, therefore, a large number of domestic enterprises engaged in packaging and application. This situation led to the domestic LED industry to low-end products, the company is facing a severe price pressure for a long time.

According to the reporter, at present, with the national semiconductor lighting project started, the development of the LED industry "Shen" is changing, upstream of the LED industry has been developed rapidly, the chip industry is most noticeable. But the scale of industry, the industrial chain is still the largest package in LED industry. 2006 China's LED industry output value reached 10 billion 550 million yuan, of which the output value of packaging industry reached $8 billion 750 million. Wang Ying analysts believe that the continuous expansion of market demand and the government's strong support is to ensure that the development of LED industry favorable factors. In recent years, such as display, landscape lighting, traffic lights, automotive applications, such as the rapid rise of backlight LED application market. Emerging applications market LED luminous efficiency requirements continue to promote the birth of the demand for high-end products. With the increasing market demand, LED chip industry to accelerate the pace of product upgrades, LED chip products will be the overall high-end. On the other hand, the rapid development of LED packaging industry, but also for the LED chip provides a broad market demand, which provides a good external environment for the development of LED industry.

The state has also given strong support to the development of LED industry. In 2006, according to the current development of China's semiconductor lighting industry, the relevant departments to develop the semiconductor lighting industry development plan and the 2006 technology roadmap proposed for LED chip LED industry investment will account for 20% of the investment, the research will focus on GaN chip production and R & D power chips.

Although it has great market demand and the strong support of the relevant departments, but it is undeniable that the current LED chip industry still exist the lack of core technology, the lack of professionals, product quality is not high, the ability of independent production equipment and weak development dilemma. How to solve these problems is the key to the sustained and healthy development of China's LED industry.

Wang Ying believes that the rapid development of the LED chip industry will boost the overall upgrading of the LED industry. In the development process of the LED chip industry, the early products are mainly based on the general brightness chip, the manufacturers are only a few Nanchang Xin lei. After 2003, in Xiamen, Dalian Road, three United States as the representative of the chip production enterprises according to the requirements of the chip market, their products focus to high brightness chip, directly led to the rapid growth of high brightness chip production. For a time, the domestic set off a boom in the development of the LED chip industry, high brightness chips become the main driving force for the development of LED chip industry. 2006, China's LED chip production reached 30 billion 930 million, the output value reached $1 billion 190 million.

With the LED chip production enterprises continue to increase, LED chip output growth rate has been higher than the part of the package, resulting in chip output accounted for in China's LED industry output value in the proportion of the rise, up from 5.4% in 2006 to 11.3% in 2002. Thus, China's LED industry is moving from low-end to high-end, high value-added, more core value of the chip forward.

According to Wang Ying predicted that in 2008 the production of high brightness chips will exceed the ordinary brightness chip, LED chip industry into the era of high brightness. For a long time, companies will focus on the production of high brightness chip.
