After years of development, China's LED industry chain has become increasingly perfect. However, Wang Ying, an analyst at CCID Consulting's Semiconductor Industry Research Center, told reporters recently that looking at the LED industry chain, due to the high demand for technology and capital from the upstream industry, domestic enterprises are rarely involved, so there are few companies in the upstream industry. Small size features. In contrast, downstream packaging and applications have relatively low capital and technical requirements for enterprises, which coincides with the characteristics of domestic enterprises with less capital and weak technology. Therefore, there are more enterprises engaged in packaging and application in China. This situation has led to the domestic LED industry mostly dominated by low-end products, and enterprises have faced severe price pressures for a long time.
According to the reporter's understanding, at present, with the launch of the national semiconductor lighting project, the development of the LED industry is changing. The LED upstream industry has developed rapidly, and the development of the chip industry is the most eye-catching. However, from the perspective of industry scale, packaging is still the largest industry chain in the LED industry. In 2006, the total output value of China's LED industry reached 10.55 billion yuan, of which the packaging industry output value reached 8.75 billion yuan. Wang Ying believes that the expanding market demand and the strong support of the government are favorable factors to ensure the development of the LED industry. In recent years, LED application markets such as display screens, landscape lighting, traffic lights, automotive applications, and backlights have sprung up. The increasing demand for LED luminous efficiency in the emerging application market has created a demand for medium and high-end products. As the market demand increases, the pace of LED chip industry product upgrades will gradually accelerate, and LED chip products will move toward high-end as a whole. On the other hand, the rapid development of the LED packaging industry has also provided a broad market demand for LED chips, which in turn provides a good external environment for the development of the LED industry.
The state has also given strong support to the development of the LED industry. In 2006, according to the development status of China's semiconductor lighting industry, the relevant departments formulated the semiconductor lighting industry development plan and the 2006 technology development roadmap, the investment in LED chips will account for 20% of the LED industry investment, and the research focus will be on GaN chips. Production and development of power chips.
Although it has great market demand and strong support from relevant departments, it is undeniable that at this stage, the LED chip industry still has development difficulties such as lack of core technology, shortage of professional talents, low product quality, and weak independent production capacity of equipment. How to solve the above problems is the key to the sustainable and healthy development of China's LED industry.
Wang Ying believes that the rapid development of the LED chip industry will boost the overall upgrade of the LED industry. In the development process of the LED chip industry, the early products mainly used ordinary brightness chips, and the manufacturers only had a few such as Nanchang Xinlei. After 2003, chip manufacturers represented by Xiamen Sanan and Dalian Lumei focused on the demand of the chip market, and concentrated their products on high-brightness chips, which directly led to the rapid growth of high-brightness chip production. For a time, China has set off a boom in the development of the LED chip industry, and high-brightness chips have become the main driving force for the development of the LED chip industry. In 2006, China's LED chip production reached 30.93 billion, with an output value of 1.19 billion yuan.
With the increasing number of LED chip manufacturers, the growth rate of LED chip production value has been higher than the packaging link, resulting in the proportion of chip output value in China's LED industry output value has increased, from 5.4% in 2002 to 2006. 11.3%. It can be seen that China's LED industry is moving from low-end to high-end, and is moving toward a chip with higher added value and more core value.
According to Wang Ying, in 2008, the output of high-brightness chips will exceed that of ordinary brightness chips, and the LED chip industry will enter the era of high brightness. For a long time, companies will focus their investments on the production of high-brightness chips.
