The LED is so beautiful, attracting countless heroes to compete. Recently, Tsinghua Tongfang announced that it will invest 3 billion yuan to build a comprehensive industrial base for high-brightness LED applications in Nantong, Jiangsu. This is another key step in the LED industry chain after Tsinghua Tongfang has established LED chip and LCD TV LED backlight industry bases in Beijing and Shenyang.
"The goal of Tsinghua Tongfang is that in 2011, the production scale of LED chips reached the first place in China." Lu Zhicheng, president of Tongfang Co., Ltd. said that Tsinghua Tongfang will strive to become the largest and top three chip supplier in the country in the next three years.
Seeking breakthroughs in core links
China's LED lighting industry is in a blowout period, and LED lighting industry is one of the pillars of developing strategic emerging industries in many places (such as Guangdong, Jiangsu, Hubei, etc.). However, the strength of China's LED lighting industry is downstream packaging. In the upstream key areas of epitaxial wafers and chips, the power is weak.
Li Xinghua, director of the Science and Technology Department of Guangdong Province, who is highly concerned about the development of the LED lighting industry, has repeatedly stressed that China's LED industry has formed a strong technical and industrial base in packaging and application, but in the upstream of the industrial chain, especially the epitaxial chip, it is still relatively Weak, we must increase our independent innovation and make breakthroughs in key and core technologies. Otherwise, it is very likely that it will fall into the two major drawbacks of price war and heavy dependence on key components. The upstream resources are controlled and the initiative of pricing is lost.
Wang Lianghai, vice president of Tongfang Co., told reporters that Tongfang shares rely on the relevant technical strength of Tsinghua University's LED industry. At the same time, the well-known LED research institutes outside the United Nations have mastered the high-level development, research and introduction through the digestion and absorption of international advanced technologies. The core key technologies of brightness blue-green LED epitaxial wafer growth and chip preparation engineering quickly have the technical strength to be in line with international standards.
It is understood that after the completion of the Tsinghua Tongfang investment of nearly 3 billion yuan in the Nantong LED project, it will form an annual output of 1.92 million high-brightness blue-green LED epitaxial wafers, 2 million LED backlight modules, and 2 million LED LCD TVs. 1 million LCD TVs and 500,000 Blu-ray DVDs, 16 million LED lamps and 9.6 million sets of wire and power board processing capacity.
"With the completion of Tsinghua Tongfang Nantong LED semiconductor base, it will change China's weak position in the field of high-brightness, high-power LED epitaxial wafers and chip production, which is conducive to China's independent development of the LED industry, while driving raw materials, midstream LE D devices and Packaging, and the development of downstream LED applications." Wang Lianghai said.
Layout LED industry chain
China is almost at the same starting line with the developed countries in the LED industry, which also gives Chinese companies the opportunity to participate in global competition. According to the national "Semiconductor Lighting Energy-Saving Industry Development Opinions" clearly stated that by 2015, key raw materials and more than 70% of the chips will be localized, and 3-5 upstream chip manufacturers will be produced.
China's LED companies, such as Sanan Optoelectronics, Silan Micro and other listed companies, the development model is basically in the industry chain to focus on one link to become bigger and stronger, and Tsinghua Tongfang chooses the whole industry chain development model. According to Wang Lianghai, at present, Tsinghua Tongfang has formed LED epitaxial wafer, chip manufacturing and packaging, production and application of terminal products, complete industrial chain and large-scale production of urban landscape lighting, and has patents for LED epitaxy and chip manufacturing nearly 30. item.
Due to many patent problems in the technical aspects of epitaxial wafers, chips, packages, etc., multinational giants such as Sem iLED sCorporation in the United States and Lem nis in the Netherlands are building huge patent pools, which threatens the long-term development of China's LED industry. In terms of patents, Tsinghua Tongfang and the Dutch Lem nis company cooperated to solve the patent problems in the European and American markets through cross-licensing. This also paved the way for Tsinghua Tongfang to go overseas.
Lu Zhicheng emphasized that with the construction of Nantong LED industry base, the layout of Tsinghua Tongfang LED industry has been basically completed. In China, the realization of high-brightness, high-power LED epitaxial wafers and chip-scale production is conducive to changing the monopoly of high-end products to foreign countries, reducing production costs and improving the international competitiveness of China's LED industry.
