The development of OLED industry in China must penetrate into the core technology field

Following the odd crystal, China's Taiwan and Sichuan, RiTdisplay irisopsia, CIGNA, Xinli electronics investment OLED (organic light-emitting diode) production line, joint investment by the Shanghai Univer and SVA 2.5 generation line will start construction next year, marking China's OLED as the representative of the new display technology into the initial stage of the industry. China lags behind Japan and South Korea in LCD (liquid crystal), PDP (plasma) and other relatively mature display technology. Although China has a large scale manufacturing capacity of the whole machine, but in the face of the panel, modules and other core components rely heavily on imports, greatly weakened the overall competitiveness of enterprises in the global market. The high hopes of OLED this new display technology, although still lags behind Japan and South Korea, but the gap between China and their relatively small, it can be said that OLED is the hope of China's flat panel display industry. The author believes that the development of China's OLED industry must penetrate into the core technology field, especially in the large scale OLED technology breakthrough. Under the guidance of the national industrial policy, we should take the road of joint development of research institutions, universities and enterprises.

First of all, the enterprise should at least grasp some of the core technology of OLED, occupy a favorable position in the OLED industry chain. Most of the LCD technology in the hands of the Japanese and Korean companies, which doomed the Chinese enterprises in a passive position. Most of OLED's patented technology is applied after 2003, Chinese enterprises through the purchase, independent research and development, in the device structure, technology, materials and other fields have the key technology. Statistics show that the current OLED technology related patents about 16 thousand, of which Japan accounted for about 63%, South Korea accounted for about 12.8%, the United States accounted for about 12.2%, China accounted for about 7.7%, Germany accounted for about 2%. At present, the basic OLED technology mainly lies in the Kodak (Kodak), UDC (Universal Display Corp), CDT (Cambridge technology company) the hands of three companies, although SONY, Samsung SDI leading in OLED technology, but also on the basis of these leading technology to digest the three technology on research and development to the. Chinese companies can also be digested and absorbed, to achieve breakthroughs in key technologies.

Secondly, universities, research institutions, enterprises must take the road of joint development, not individual combat. At present, OLED (organic light-emitting diode) technology level is still in pre production scale, Tsinghua University, Shanghai Univer, South China University of Technology, University of Electronic Science and technology, Changchun Institute of Applied Chemistry Research by the universities and research institutions are doing in the field of devices and materials; Changhong, BOE in OLED technology is achieved through the acquisition of reserves the way; CIGNA Corporation technical support is the support of Tsinghua University, SVA is Shanghai Univer. On the whole, the research of OLED technology in our country is taking a diversified development route, which is beneficial to the long-term development of the industry. But I still suggest that, like Changhong, and these enterprises should be more involved in the development of OLED technology, so as to make the development of OLED technology as soon as possible out of school ideas, accelerate the industrialization process.

Japan and South Korea in the enterprise to do better, and they are not individual combat, Samsung Electronics and Samsung SDI, Hitachi and Canon are joint development.

Again, the government to give more support in basic research, research and development and industrial promotion funds should be diversified financing channels. From a global perspective, governments have given a lot of funding and policy support: for example, the Japanese government will invest 350 million yen in the next three years ($32 million 780 thousand) funding; in the South Korean government's support, Samsung also plans to invest $529 million in research and development of large size OLED display. Experts are expected to invest in a OLED panel production line requires only LCD of the 1/3 panel, about 2 billion yuan, large enterprises can afford. I believe that our government can support the OLED technology research and development and promotion through the establishment of industrial development fund, direct investment in research funding, direct funding and so on; enterprises can solve the problem of funds through equity financing, the State Development Bank lending, commercial bank loans etc.. On the whole, the development of China's OLED industry funds should not be a problem.

Finally, China's OLED investment in the future should focus on the development of large-scale active OLED technology and industrial promotion. Although shipments RiTdisplay Corporation in the world, but they are passive (PMOLED) small size products, Sichuan rainbow, also produced only visionox PMOLED, but experts believe that the technical direction of OLED should be AMOLED. At present, almost all of the OLED manufacturers, including SONY, Samsung SDI, LGD, odd crystal, pioneer and other uses AMOLED technology. Market research firm DisplaySearch predicts that AMOLED's sales growth this year will exceed 69%, sales of more than $826 million 500 thousand next year will reach 83%. ISuppli also believes that by 2014 the global AMOLED market will rise from $67 million last year to $4 billion 600 million, especially in the TV market. The world's OLED products are mainly small size PMOLED devices, the real threat to the LCD display technology is now AMOLED technology, but the production of only a few companies. So, in the future, Chinese OLED manufacturers must focus on AMOLED. We are pleased to see that the SVA and Shanghai Univer project using the AMOLED technology, by the end of the rainbow Sichuan is also expected to develop 3 inch AMOLED products.
