Company News >> Hundreds of billions of dollars to pound flexible AMOLED China panel makers must be back in the water 28th,Nov,2017
                                              In the past five years, mainland China showed that the industry has undergone tremendous changes. As the LCD industry continues to grow, the OLED industry in mainland China has set off a new round of investment wave. This at least two or three trillion yuan of production line are aimed at the flexible AMOLED. Visteon's representative Dr. Zhang Deqiang believes that the Chinese OLED industry is facing better opportunities for development. In terms of R & D, mainland China is in sync with the rest of the world. In the process of industrialization, mainland China is following Japan and rushing ahead of Japan .

However, AMOLED flexible without previous experience, Chinese panel makers need to explore their own, facing enormous challenges. Liang Xinqing, vice chairman and secretary general of China Optics and Optoelectronics Industry Association LCD Branch, pointed out that panel companies in mainland China have invested so many flexible AMOLED production lines now that they have not retreated and must fight back.
Flexible AMOLED have the opportunity to achieve overtaking overtaking
In the past ten years, the LCD panel industry in mainland China started from scratch and will soon surpass its production capacity by introducing, digesting, absorbing and re-inventing. Compared with the LCD, the technology foundation of OLED in mainland China is better. In the short 30-year history of OLED, China already has a 21-year-old OLED enterprise such as Vicenzo. In OLED technology research and development, Chinese mainland enterprises and South Korea started almost simultaneously. Precisely because of this, WISINO dominate the formulation of international flexible display standards, in the international community has a certain technical discourse.
In the OLED industry, although the panel makers in mainland China lag behind those in South Korea, mainland Chinese companies are following the pace of Korean businesses through the heavy investment over the past two or three years. Viginol, BOE, Pegasus, and Hui Optoelectronics, China Star Optoelectronics, Shun Lee, soft-woofing are in full swing investment in the construction of new production lines, hoping to be the first to share a flexible AMOLED market share. Flexible Vinyto panels like Visionosyn have been mass-produced and implemented in terminal manufacturers.
Dr. Xiu-Hsuan Huang, Head of Visionocenocon Technology believes that OLED technology has not yet been finalized yet. The chance of OLED in mainland China is greater than that of LCD. When the introduction of liquid crystal production line in mainland China, LCD technology is more mature, it is difficult to compete with competitors. But now OLED technology is not very mature, different technology routes are still in sync with the development and competition, out of them, the Chinese mainland enterprises have the opportunity to OLED technology to a more mature stage. At the same time, just because the OLED technology is immature and needs to be improved, the leader will form a certain technical barrier, but it takes more time to explore, and the developer may have a greater advantage because the late partner has more Support, faster in research and development and production speed faster than the leader. Xie Qinyi, general manager of IHS Display Research, also pointed out that the domestic manufacturers have followed the example of Samsung, the learning curve will be shorter.
For flexible display technology, is still in the early stages of development. Zhang Deqiang believes that the development of flexible display technology can be divided into three stages, the first stage is to achieve curved screen, a full screen; the second stage is to achieve folding display; to the third stage is to achieve free curly display Screen. Huang Xiuli pointed out that precisely because the flexible AMOLED is not stagnant, but also constantly updated changes among Chinese panel companies as long as the opportunity to take the opportunity to achieve the changeover overtaking.
Flexible AMOLED faces ecological challenges
China AMOLED flexible flexible opportunities, the same huge challenge. HUANG Xiu-yan By combing upstream, midstream and downstream of flexible AMOLED, it is found that the challenge of flexible AMOLED is not only from the single-factor challenge of panel makers. Flexible AMOLED is likely to reshape the terminal supply chain. So the bigger challenge of flexible AMOLED is from ecological chain challenge.
From the midstream manufacturers point of view, if AMOLED from rigid into the flexible stage, panel makers will face the problem of stress management and control. Stress control will involve the design of the panel stack structure, and the difficulty of the stack structure design is to simultaneously meet the electrical performance, optical performance and mechanical properties, but also to achieve the balance of the three. If the flexible AMOLED enters the curl screen stage, it may be necessary for other types of manufacturers in the midstream to follow the breakthrough, for example, flexible circuits, flexible batteries, flexible structures and flexible materials.
From upstream manufacturers, AMOLED may require new materials, components, equipment, such as substrate PI, packaging materials, OCA and other materials, flexible cover plate, ultra-thin polarizer, support film, flexible touch Control and other components, PI coating curing equipment, ALD and TFE equipment, laser stripping equipment, COP equipment, flexible laminating equipment. Huang further pointed out that the rigid LCD module to the rigid AMOLED module is not difficult when the transfer, but after the soft stage has become less easy, to the foldable stage and even the material at all. Polarizer in the past is very thick, but flexible AMOLED need thinner polarizer, the original polarizer may need to change the material.
From the downstream manufacturers point of view, to the folding screen stage, the terminal manufacturers need to consider the bending part of the hinge design, software, operating system level should also be optimized. Huang Xiuxiu stressed that the terminal manufacturers have not yet determined the final shape of the folding screen phone, which has a great impact on the upstream and midstream manufacturers, for example, if you are not sure the folding screen phone is folded or out of the fold, the upstream manufacturers have to do both options, This is equivalent to twice the time, money, energy to research and development, terminal manufacturers decided to take the lead. AMOLED into the flexible phase, the upstream, midstream and downstream interaction, mutual restraint.
Liang Xinqing also pointed out that domestic AMOLED industrial atmosphere and the actual level of a certain gap, the LCD industry is relatively mature, equipment, materials and processes stable, easier, but too many places for OLED uncertainty, South Korean manufacturers shadow mask shape and pixel arrangement Has been adjusted, which also shows that OLED technology and material instability, equipment is also being improved OLED is still in the process of research and development and mass production of mutual promotion. From the evaporation, the number of OLED evaporation, repetition rate, precision control requirements, exposure times from 5 to 11 times, the difficulty is very large, it is not yet completely resolved.
