In June this year, the Ministry of Industry and Information Technology announced the results of the bidding for the AM-OLED (Active Active Drive Organic Light Emitting Diode) project by the Electronic Information Industry Development Fund. The Ministry of Industry and Information Technology gave Visionox, BOE, and Hongshi 3 respectively. The corresponding financial support of the home business. The government's strong support for the new flat panel project will become a new opportunity for China to develop large-size OLED (Organic Light Emitting Diode) technology. In terms of third-generation display technology, China's OLED industry is almost at the same starting line with foreign countries. At present, the opportunities for developing OLED industry are rare. The joint efforts of government, industry, research and research, China's OLED industry development will be able to achieve cornering beyond.
Strive to show the initiative in the field
AM-OLED is more expensive than liquid crystal display, but the gap is not obvious. For special application groups such as high-end mobile phones, the market space of AM-OLED is still relatively large. From an international point of view, in order to truly surpass Japan and South Korea in display technology, China must develop emerging technologies, and OLED is the best opportunity.
Ouyang Zhongcan, an academician of the Chinese Academy of Sciences, said in an interview: "If China only develops LCDs, there is a problem. After all, LCD is a relatively mature technology in Japan and South Korea. We have been chasing the role. Developing our own flat panel display. Technology, AM-OLED is worth a try. From the development of China's flat panel display industry, OLED is at the same starting line with the international level; from the perspective of strategic development, we can only actively pursue OLED in the future.
Xu Wei, from the Institute of Polymer Optoelectronic Materials and Devices of South China University of Technology, said in an interview that in recent years, liquid crystal technology has developed very fast. Relatively speaking, the advantages of OLED in application are not obvious. At present, OLED has just developed, and the international and domestic are basically at the same starting line. The development of liquid crystal technology in foreign countries has been relatively mature, and we are in the catch-up phase in the liquid crystal industry. China's OLED industry must develop upstream and downstream linkages. Upstream materials are the bottleneck for the development of the OLED industry. If there is a breakthrough in upstream materials, it will promote China's OLED industry.
The three companies that have won the Electronic Development Fund can be said to have their own characteristics. BOE has a TFT technology base, and Visionox has experience in the production of PM-OLED, and the development of Hongvision in recent years is obvious to all. If the three companies can jointly develop, the opportunities for China's OLED industry to take the initiative in the future will be even greater.
In this regard, Academician Ouyang suggested that although Visionox has experience in PM-OLED, AM-OLED technology is still immature. In this case, it is possible to conduct research through mastering the pilot test line, master the technology, and form its own core competition. force. BOE has TFT experience, how to apply TFT technology to OLED, to overcome material bottlenecks, especially low-temperature polysilicon technology is worth studying.
AM-OLED is the first breakthrough
From a market perspective, the OLED market is a promising market. AM-OLED has a strong dependence on TFT-LCD. Without the foundation of TFT-LCD, it is very difficult to develop AM-OLED.
Hu Jun, assistant to the president of Truly Semiconductor Co., Ltd., believes that the OLED industry will grow up, but it may not be developed in the way of replacing TFT-LCD as expected, but coexist in various application fields. From the maturity of the industry, the OLED industry has matured considerably compared to two years ago. At present, there is no second company in South Korea, Samsung, which can stabilize, mature and supply a large number of products. At present, terminal manufacturers including Nokia and Apple are still afraid to apply a lot of products on their own products. If the second and third companies can reach the supply level of Samsung, the application of OLED in the current market will certainly expand. And it will expand by an order of magnitude. At present, the demand for OLED market is very large. As far as the domestic market is concerned, the first-line brands of mobile phones have the desire to apply OLED, but they are suffering from insufficient supply. From the perspective of OLED product and industry maturity, the product is mature, but the industry is not mature. A big reason is that OLED supply is highly concentrated. 95% of AM-OLED products are from Samsung. In fact, this is an industry. Very immature performance.
Peng Hongbing said that he hopes that through the support of the Electronic Development Fund, the core technology of OLED can be made a breakthrough, especially in the field of AM-OLED, it is necessary to form a certain pilot test capability, and a production line with a certain capacity can be built in the next few years. He hopes that in the future, there will be products for small and medium size applications. "This is a relatively clear near-term goal," he said.
Wang Dazhao, director of the technical management center of BOE Technology Group Co., Ltd., believes that TFT-LCD and AM-OLED have great industrial commonality and acceptability. In the field of TFT-LCD, China has a certain industrial base. To carry out the forward-looking technical layout of AM-OLED, on the one hand, we must continue to pay attention to the development trend of technology, and have a clear grasp of the development trend of technology; on the other hand, we must pay attention to the continuity and inheritance of technology and industrial development, and actively use existing Foundation, joint upstream and downstream resources of the industrial chain, looking for breakthroughs in technological research.
Japan and South Korea are still developing OLED
A new product comes out, can not promote the price is the most critical. Vinita Jakhanwal, chief analyst of iSuppli's small and medium size display, once said that although Samsung is still promoting AM-OLED products, the technology of LCD (liquid crystal display) is developing rapidly, and the performance of the product is improving rapidly. Currently, the distance between AM-OLED and various indicators is AM-OLED. The gap is getting smaller and smaller, but because the price of AM-OLED products is too high, she is very confused about the prospect of AM-OLED. Perhaps it is the large investment and high cost of OLED that makes it develop twists and turns.
Recently, Japan’s news of promoting the development of the OLED industry is endless. In this interview, Ouyang Zhongcan said in an interview that Japan has always been at the leading position in OLED R&D, but in the industrialization of large-scale products, the yield is too low. The cost is too high, and it can't compete with the liquid crystal display (the current yield of liquid crystal is above 90%). The so-called "exit" in Japan is not to stop the research, but the pace of mass production is slowed down, but it is temporarily "exited." Peng Hongbing, director of the Department of Basic Products Division of the Department of Electronics and Information Technology of the Ministry of Industry and Information Technology, stressed in an interview that Japan has never given up on research on OLED technology, but it has slowed down due to cost and other reasons in terms of industrialization. In general, OLED technology research in various countries is constantly advancing. No one has announced that they will give up. However, the technical routes are slightly different and the promotion strategies are different. This requires special attention.
By analyzing the development of the OLED industry in Japan and South Korea, it is not difficult to find that Japan has no Korean obstinacy in developing large-size AM-OLEDs, or that there is no South Korea to invest. For OLED technology, Japan has not given up. Many core technologies, raw materials and equipment are actually controlled by Japan. Once the market demand is enlarged and the industrialization of its technology is further improved, Japan will definitely enter the field of OLED production. South Korea has begun to make large investments in technology, or at the beginning of technology development. Korean companies may have more experience in the industrialization of technology. In terms of developing OLEDs, Japan and South Korea rely on government support, and Japan relies on corporate alliances. In China, government support is limited and companies are reluctant to unite. In this regard, Peng Hongbing said that enterprises are not strong, government support is not strong, and the two are not forced together. In the future industrial commanding heights, the competitive disadvantage is very obvious, let alone the advantage, so we have hidden dangers in the development of OLED industry. of.
How to eliminate hidden dangers and realize the leap-forward development of China's OLED industry. On the one hand, we must increase government support. This kind of support is not only the support of funds but also the support of policies and other aspects. On the other hand, it is necessary to strengthen the alliance and cooperation of upstream and downstream industries. Only in this way can China achieve the cornering of the third generation of display technology.
