TFT-LCD and AM-OLED have great industrial commonality and inheritance. In the field of TFT-LCD, China already has a certain industrial base. At present, it is necessary to carry out the forward-looking technical layout of AM-OLED, and actively use the existing foundation to find a breakthrough in technological breakthroughs. The main technologies of AM-OLED (Active Active Drive Organic Light Emitting Diode) include TFT (Thin Film Transistor) technology and OLED (Organic Light Emitting Diode) technology. As a leader in the display field of China's core technology for TFT-LCD (Thin Film Transistor Liquid Crystal Display), BOE takes advantage of BOE's technology accumulation and industrialization advantages in TFT, integrates resources, and adopts Group Technology R&D Center and National Engineering in technology research and development. The laboratory's 2.5-generation LTPS (low-temperature polysilicon) experimental line has set up relevant project teams, and has carried out research and development of key AM-OLED technologies. In terms of mass production, through the transformation of the 4.5th generation TFT-LCD production line of BOE Chengdu, the related planning and preparation work began. The accumulation of TFT technology laid the foundation for the development of AM-OLED TFT-LCD and AM-OLED have great industrial commonality and acceptability. The key driver backplane part of AM-OLED and the existing TFT array process can be shared in most of the equipment and technology. A small number of TFT production lines and equipment additions can meet the development and production of future AM-OLEDs. It can be seen as a continuation of TFT technology, and BOE has long accumulated in TFT, which is the further development and quantity of AM-OLED technology. Production laid a solid foundation. First of all, BOE has a very rich platform for technical accumulation and industrialization verification, and fully masters the product technology, process technology and production technology of TFT. At present, it has mastered more than 5,000 patentable technologies, and has applied for more than 500 patents each year. At the same time, BOE also has rich experience in production line construction and operation, successfully operating the 5th and 4.5th generation TFT-LCD production lines, and has always maintained the industry's first-class yield. In addition, BOE Hefei's 6th generation production line will also be mass-produced in October this year, and Beijing's 8.5th generation TFT-LCD production line plant will soon be capped. Secondly, with a professional technical team, BOE has established a complete technology research and development system, with hundreds of professional technology research and development teams, hundreds of product development teams and more than 2,000 engineers, most of which have 5 core personnel. More than a year of actual industry experience. In addition, BOE has a very complete R&D experiment and test platform. In April last year, the National Development and Reform Commission (NDRC) independently built China's only TFT-LCD process technology national engineering laboratory based on BOE. A G2.5a-Si and LTPS R&D line currently under construction will be put into use in the second half of this year. In addition, the technical center has built a number of laboratories such as layout design, optics, electricity, machinery, performance testing, etc. The R&D and testing platform has been basically improved, which provides a solid guarantee for the development of AM-OLED display technology. Actively reserve AM-OLED technology and introduce it into production at the right time The development of large-size AM-OLEDs requires high mobility and good stability of TFT technology. At present, major manufacturers and research institutes are looking for better technical solutions to solve the problem that existing TFT technology is applied to AM-OLED mass production. The high cost issue. In response to this industry-wide problem, BOE is actively researching new TFT materials and process technologies that can produce large-size AM-OLED backplanes at lower cost, and is actively planning and implementing the development and research of cutting-edge technologies including compound semiconductors. BOE has been deeply involved in the display field for many years. Our vision is to become the world's leading company in the display field. Through innovative technology and management, we will provide customers with satisfactory display products and services and create maximum value for stakeholders. As a future mainstream display technology in a specific field, AM-OLED is also one of the focuses of BOE's active attention and research and development. BOE has carried out related technology development and reserves in AM-OLED, and has planned to introduce production at the right time. As mentioned above, AM-OLED and TFT-LCD have great technical continuity, and BOE has mastered core technology in the field of TFT, has a complete technical system and team, and successfully operates the 4.5th and 5th generation TFTs. LCD production lines, these will be our core competitiveness in the development of AM-OLED. BOE will continue to unswervingly promote the further development of the TFT-LCD business. While strengthening the capacity building of its own R&D system, it will increase its key and forward-looking product technologies, process technologies, key materials and equipment technologies for TFT-LCD. Independent innovation research and development in the field, to create a global industry-leading independent technological innovation capability, to the goal of the world's leading companies in the display field. Technology and industrial development have continuity and inheritance OLED is divided into PM-OLED and AM-OLED. Among them, PM-OLED (Passive Passive Drive Organic Light-Emitting Diode) has very limited development space in the display field. Although AM-OLED has been mass-produced, it has low output and high cost. It takes a certain amount of time to expand the market for small-sized applications, and there are still many technical problems to be solved in large-size applications, and it is impossible to achieve mass production in large-size applications such as notebook computers, monitors, and televisions. . Some Chinese companies have done a lot of work on the technical accumulation of luminescent layer deposition in the back of OLEDs, and have a certain foundation, but the large-scale research and development of TFT backplane technology for AM-OLED has just begun, and there is still a long way to go. go. On the one hand, the AM-OLED industry should 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, it should pay attention to the continuity and inheritance of technology and industrial development, and actively use the existing foundation to unite the industrial chain. Upstream and downstream resources, looking for breakthroughs in technological breakthroughs. Industry experts say AM-OLED industrialization OLED display technology is recognized as the most ideal and most promising third-generation display technology after LCD and PDP. As a new display market, the OLED industry is in the mid-stage of large-scale industrialization, which is recognized by the industry. The Ministry of Industry and Information Technology, the National Development and Reform Commission, the Ministry of Science and Technology, and local governments have given great attention and support to the development of the OLED industry. The government's strong support for new flat-panel projects has become a new opportunity for China to develop large-size AM-OLED technology. Seizing this opportunity requires the concerted efforts of the industry. Only with the concerted efforts of the industry can China's AM-OLED industrialization be rapidly advanced. Academician of the Chinese Academy of Sciences Ouyang Zhongcan LCD is a relatively mature technology in Japan and South Korea. We have been playing a catching role. How to develop our own flat panel display technology, AM-OLED is worth a try. From the perspective of China's development of the flat panel display industry, OLED is at the same starting line with the international level. From the perspective of strategic development, we can only strive for initiative in the future only if we develop OLED. Peng Hongbing, Director, Electronic Foundation Division, Electronic Information Division, Ministry of Industry and Information Technology Overall, OLED technology research in various countries is constantly advancing. Japan and South Korea are at the forefront in developing OLEDs and each has its own characteristics. South Korea is characterized by policy support and corporate follow-up. Japan is characterized by corporate alliances and government support. In China, the government's support is limited, and the desire for corporate alliance is not urgent. This is the difference between us and Japan and South Korea. Enterprises are not strong, the government's 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 the OLED industry. Wang Dazhao, Director of Technology Management Center, BOE Technology Group Co., Ltd. TFT-LCD and AM-OLED have great industrial commonality and acceptance. 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 trend of technological development, 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 the present Have a foundation, joint upstream and downstream resources of the industrial chain, and find breakthroughs in technological breakthroughs. Zhang Deqiang, Vice President of Visionox China has carried out research and development of OLED materials and devices since the 1990s, and has done a lot of work in mechanism research, material development, device structure design, production process technology, etc., and has obtained a series of valuable research results, Tsinghua University and CIGNA achieved industrialization of PM-OLED through independent research and development. AM-OLED technology is a hotspot and mainstream of global development. Tsinghua University and Visionox also attach great importance to the development in this field. Hu Jun, President Assistant, Truly Semiconductor Co., Ltd. At present, the biggest problem in OLED technology in the world is that, except for Samsung, there is no second company in South Korea that can stabilize, mature and supply a large number of products. If the second and third companies can reach the supply level of Samsung, then OLED is currently The amount of applications in the market will certainly increase, and will expand by an order of magnitude. Xu Wei, Institute of Polymer Optoelectronic Materials and Devices, South China University of Technology In recent years, liquid crystal technology has developed very fast. Relatively speaking, the advantages of OLED in application are not so obvious. 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.
