The intensified competition brought about by the expansion of production capacity will force domestic enterprises to upgrade their technological level and objectively stimulate the technological strength of China's LED chip industry. Multi-party data shows that under the impetus of lighting applications, the LED chip industry has ushered in a new round of expansion peaks, and related listed companies are also welcoming. In July this year, Sanan Optoelectronics and Huacan Optoelectronics successively released the results announcement for the first half of 2014. The former net profit increased by 40, and the latter's net profit increased by 185~215. Sanan Optoelectronics announced that with LED lighting Infiltration, demand for LED chips was strong. During the reporting period, the company's production capacity was further improved and its profitability continued to increase. The announcement of Huacan Optoelectronics also pointed out that since the second half of 2013, the growth of LED chip market demand has continued to maintain, the decline in product prices is basically reasonable, and the profitability has rebounded significantly. Relevant experts pointed out recently that, unlike the capacity expansion in previous years, the current round of capacity expansion is relatively rational, and the leading forces are mostly leading enterprises in the industry, and the industry concentration is high. At the same time, the intensified competition brought about by capacity expansion will force domestic enterprises to upgrade their technical level and objectively stimulate the technological strength of China's LED chip industry. Development into a benign track After the downturn caused by overcapacity in the past few years, the LED chip industry began to recover with the rapid growth of downstream LED lighting market demand. Since the first half of this year, the supply of LED chips has been in short supply, which has led many chip companies to start a new round of expansion. On April 3, Aoyang Shunchang issued a notice saying that it will raise 500 million yuan by means of non-public offering of shares, and will invest in LED epitaxial wafers, chip industrialization projects (Phase I) and supplementary liquidity projects. When the project is fully operational, the company's MOCVD (metal organic compound chemical vapor deposition) equipment will increase from the current 10 to 30 units. On April 4, Sanan Optoelectronics also announced that it will invest in the construction of LED blue and green epitaxial wafers and chip industrialization projects in Xiamen. The total investment of the project is 10 billion yuan and the total scale is 200 MOCVD. On the other hand, in 2010~2011, due to the explosive growth of the LCD backlight market and the high confidence of the market for LED lighting, there has been a wave of expansion, but in the next few years, because the LED lighting market has not As expected, there has been a serious overcapacity, and the development of LED chips has also fallen into a downturn. So, will the current round of expansion of LED chips cause similar problems? Yan Faxin, chief analyst of SEMI China Industry Research and Consulting Department, told reporters that although the MOCVD installed capacity will increase this year, the LED chip market has been relatively rational after the reshuffle of the past two or three years. Judging from the new round of expansion, the leading force is the leading enterprise in the industry, and the concentration of the industry is constantly improving. At the same time, LED lighting has reached a new level in terms of cost, performance and consumer perception, and the application prospect is good. Therefore, the new round of LED chip expansion will bring less risk of overcapacity. The expansion of LED chips has also brought down the price. However, in the view of Dou Linping, secretary general of the China Lighting Society, the price decline is a normal market competition. As long as the company has economies of scale, there will be no major problems. In Dou Linping's view, the sharp increase in profits of Sanan Optoelectronics and other companies in the first half of this year just illustrates the importance of scale effect. And those companies with smaller scales may be eliminated by the market because they lose their competitive advantage. The technology gap is shrinking With the development of China's LED industry, the localization rate of LED chips is also rising. It is understood that in 2013, the localization rate of LED chips in China reached 75. Although it is mainly based on imported chips in high-power lighting applications such as street lamps, it has already had a strong competitive advantage in small and medium power applications. At the same time, domestic LED chips are constantly gaining new breakthroughs in terms of technology. Analyst Han Yun said that in the field of display, the product quality and reliability indicators of Silan Mingxin's blue and green light chips have reached the international advanced level. In the LED backlight field with high consistency requirements, domestic LED chip companies also Have been involved. Although the production of flip chip is mainly in Taiwan, domestic PCC Electronics, Huacan Optoelectronics, Sanan Optoelectronics, etc. have also launched their own flip chip products. It is understood that flip chip can solve the heat dissipation problem on the one hand, and can also reduce the product defect rate on the other hand, so it is regarded as an important direction for the future development of LED chips. In the past, China's LED chips were not only relatively backward compared with Japan, Europe and the United States in the first camp, but also had a large gap compared with Taiwan and South Korea in the second camp. Through efforts in recent years, domestic first-line LED chip companies have entered the second camp, and the gap with the first camp is also shrinking. Yan Faxin said. Grasping the opportunity to expand production Today, the new wave of expansion has also brought new opportunities for the development of domestic LED chips. The expansion of production has a positive effect on the development of domestic LED chips. Han Yun pointed out that with the expansion of LED production capacity, the penetration rate of domestic LED chips will be further strengthened in the low-end and mid-range fields. At the same time, the competition brought about by capacity expansion will intensify, and it will force domestic enterprises to improve their own technical level, strive to accelerate the pace of technology research and development, and seek breakthroughs in foreign technical barriers such as high-brightness chips, so it will objectively stimulate China's LED chip industry technology. The improvement of strength. However, domestic companies still face a series of difficulties in order to achieve technological breakthroughs. Han Yun said that at present, LED chip companies in Japan, the United States, Europe and other countries are continuing to increase investment in research and development of new technologies, and strive to improve the luminous efficiency of LED chips and continue to consolidate the high-end position in the industry chain. In terms of patents, a large number of core patents are currently in the hands of international giants such as Japan's Nichia, American Corey, and Germany's Osram. The patent strength of Chinese companies in epitaxial wafers and chips is relatively weak, and most companies are still unable to solve the intellectual property issues involved in exports, so it will have an impact on the future expansion of international business. However, China's LED chip companies also have their own advantages, that is, they have a broad market. For Chinese companies to enter the international front line, they must continue their efforts in technological innovation and application innovation. China's enterprises have grown stronger, and the penetration rate and level of domestic LED chips will naturally increase. Han Yun said.
