A new display industry represented by OLED technology, China is moving to the highest peak in the world

OLED is the abbreviation of organic light-emitting diode, which can be widely used in mobile phones, digital video cameras, DVD players, notebook computers, car audio and television products.

AMOLED is a next-generation display technology based on OLED. Its screen is not only very thin, but also flexible and curled, which is less susceptible to damage than the LCD screen of a glass substrate.

“Pan-in-screen” is a widely recognized concept in the display industry. It refers to the breakthrough mass production of flexible display technology in the context of the Internet of Everything, making “display everywhere” a reality.

Recently, China's first full-scale independent intellectual property rights of the 6th generation full-flex AMOLED production line in Hebei Gu'an Industrial New City officially caused widespread concern. Liang Xinqing, executive vice president of China Optical Optoelectronics Industry Association LCD Branch, said that the production line The operation is a milestone for the development of China's information industry, which will effectively enhance the overall strength of China's OLED industry to participate in international competition and enhance China's position in the global electronic information industry.

With the wide application of smart internet technology, an interconnected ecological matrix with display-centric, intelligent terminals, smart home, Internet car, artificial intelligence and other scenarios is being formed. Huang Xiuzhen, vice president of Visionox and president of Visionox Innovation Institute, said that the connection of all things is inseparable from the port, indicating that it will become an important port for human-computer interaction. Liu Xiaodong, vice president of BOE Technology Group, believes that the current number of ports is growing rapidly. The number of new ports continues to grow at a rate of 5,000 per minute. It is expected that by 2025, there will be more than 70 billion ports worldwide.

In Liu Xiaodong's view, from the past information display to the current human-computer interaction, and then to the future of artificial intelligence, the evolving Internet port will eventually become the port of universal connection, which provides a huge space for the display industry to flourish. . "If the user's point of view, the integrated interactive function of the screen will become more and more extensive, such as the combination of the screen fingerprint and the chip, the display screen can be more than a simple visual interface, but become a human-computer interaction. Center.” Huang Xiuzhen emphasized that the display will be everywhere, and a “pan-screen” era that profoundly changes the development of people and society has arrived.

"In the 50 years since the invention of liquid crystal display, China has been the latecomer in the display field. The new display industry represented by OLED technology is reaching the highest peak in the world." At the 6th China OLED Industry Development Forum held recently, the Chinese Academy of Sciences Ouyang Zhongcan introduced that in May 1968, the US RCA company's "use of liquid crystal can manufacture ultra-thin displays" opened the curtain for the global development of LCD panels, experienced nearly 20 years of industrial transformation, Japan as the LCD era The status of the founder was replaced by South Korea, which showed that the industry began to show its strength after decades of hard work and gradually became the focus of the global display industry.

The data shows that in 2017, mainland China's display industry revenue reached 200 billion, a year-on-year increase of 37%, and its business shipments have surpassed that of South Korea, ranking first in the world. Among them, the scale, technology level and competitiveness of the new display industry continue to increase, especially in the field of new AMOLED panels, Chinese companies are catching up.

According to statistics, in terms of OLED production capacity, Korea has 10 production lines, 2 in Japan, 1 in Taiwan, and 14 in mainland China. With the active layout of BOE, Visionox, Huaxing Optoelectronics and other manufacturers, it is expected that AMOLED production capacity will be fully released by 2020. By then, China will jointly lead the development of the OLED industry with South Korea. In Huang Xiu's view, flexible AMOLED is one of the best solutions in the "pan-screen" era so far. It is expected that the AMOLED market will reach 71.7 billion US dollars in 2020, of which flexible AMOLED will reach 47.7 billion US dollars.

As a basic, leading and strategic industry, the new display industry is rapidly inseparable from the guidance of national macro-policies and the active participation and assistance of local governments. It was learned from the 2018 National Electronic Information Industry Work Symposium held recently that the "Three-Year Action Plan for New Display Industry Beyond Development" jointly prepared by the Ministry of Industry and Information Technology and the National Development and Reform Commission will be released soon. The plan will further clarify the new display industry. Development timeline and road map. Experts said that China's display industry development can not only stay in production capacity, we must seize the key window of OLED industry development, make forward the technical layout, improve supporting and enriching applications, and achieve development beyond the good industrial ecology.

In the "pan-screen" era, a large number of high-definition visual effects, virtual display, enhanced display and other technologies, flexible display technology as one of the most disruptive innovations, will carry consumers' high-level demands for scientific and technological progress. From the perspective of showing the development of the industry, its own development is inseparable from market demand. "In the past, all terminals were limited by the form of the display, but flexible OLEDs have enough ability to release people's imagination of the future." Huang Xiuzhen emphasized that in the "pan-screen" era, the industry chain will be based on user needs. The panel manufacturers, upstream and downstream manufacturers are connected to form a complete set of OLED ecological network; outside the industrial chain, an industrial ecological matrix with OLED as the core element and connected with the Internet of Everything is formed.

Liu Xiaodong admits that the industry chain needs cooperation and cooperation. For example, only the flexible screen is far from enough. It also needs the cooperation of display circuits and the cooperation of batteries. These need to be solved by the whole industry. "Technical innovation will ultimately be implemented. In addition to improving product performance, we must also reduce costs through technological innovation." Huang Xiuyan said.
