Recently, the 2017 Japan Touch Panel Exhibition (FINETECH JAPAN 2017) was held in Tokyo. At the show, both upstream materials and equipment manufacturers, as well as downstream panel manufacturers, are exhibiting OLED, 8K and IoT related exhibits. Especially OLED, although LCD is still the mainstream, but more manufacturers turn their attention to OLED, OLED has become particularly dazzling.
Of course, 8K is a topic that has been avoided for two or three years. Not only Japanese panel makers, but also Chinese panel makers, are very active in deploying 8K displays. Japanese TV station NHK has said that it will achieve 8K resolution TV signal coverage by 2020, which means that the demand for 8K market will grow rapidly by 2020.
For the display industry, the larger market comes from the Internet of Things market. The interaction between people, people and things, and things and objects is inseparable from the interactive interface, and the display panel is an indispensable human-computer interaction interface, even It is the future of VR and AR, and the display panel has its indispensable side.
Printed OLED has a bright future
Although two well-known Japanese companies, JOLED and Sharp, have not set up their booths to display their products, countries have shown that industrial chain enterprises, including liquid crystal, target materials, equipment and other industrial chain upstream enterprises, have brought many new products and new technologies. It also brought a lot of surprises to the industry.
And OLED is one of the most noteworthy highlights. Wisechip, a OLED manufacturer that has been exhibiting for many years, exhibited the newly developed transparent and soft PMOLED this year. Although Raystar is exhibiting for the first time in Japan, it has also exhibited various PMOLED products.
One of the most not to be missed is the booth of the Semiconductor Energy Laboratory, which not only displays 8K OLED panels, automotive curved OLED displays, new generation oxide semiconductors (OSFET IGZO), but also exhibits a combination. A composite display of OLED and ECB liquid crystal (which can be switched in three modes of self-luminous OLED, composite display, and reflective liquid crystal according to the illumination of the surface of the display panel). These products fully demonstrate the strength of Japanese OLED technology.
Japan's JOLED company CTO Tianji Mizhi said at the meeting that JOLED was founded in 2015, the main technology is from Panasonic and Sony, and the research and development of the two companies in printing OLEDs began in 2006, and there are already 12-inch, 19-inch, 21.6-inch products are available. Currently Samsung focuses on small-size OLEDs, LG Display focuses on large-size OLEDs, and JOLEDs have the advantage of medium-sized OLEDs. At present, JOLED has successfully developed 21-inch printed OLED products and has achieved mass production.
At the same time, JOLED has accumulated a large number of technical patents on medium-sized OLEDs, and has achieved results in many aspects. JOLED has developed the world's first OLED panel product that uses "printed" technology (using liquid luminescent materials as precisely as a printer on a substrate), and its manufacturing costs have dropped dramatically. Tian Haojizhi hopes that JOLED will cooperate with materials manufacturers and manufacturers in the future to make greater breakthroughs in printing OLED panel technology.
Although Japan has a wealth of technology accumulation in OLED, but currently at the forefront of OLED marketization is the Korean panel maker. In Byeong Kang, Senior Vice President of LG Display in Korea, shared the future application of OLEDs on display and the development trend of OLED TV market. He believes that although the current number of OLED TV products may only account for a small share of the global demand, the market share will reach 50% after 2023. At the same time, he also believes that the continuous breakthrough of printed OLED technology will bring great benefits to the application of large-size OLED.
Since printing OLED is the future direction, many domestic manufacturers are also actively deploying forward-looking technologies, among which Huaxing Optoelectronics is a very active manufacturer. Huaxing Optoelectronics CoO Zhao Yong said that the process and materials of LCD and OLED were analyzed and compared, pointing out that printing OLED is the key technology in TV display in the future. At the same time, Zhao Yong also believes that smart phones will adopt OLEDs from 2018, and will account for 50% of the market share by 2023, while markets such as Pad and NB will be eroded or even disappeared, and will be folded by OLEDs. replace. Of course, these trends and the future depend on the efforts and input of materials and equipment manufacturers.
8K will usher in rapid development
In addition to OLED, 8K is still a topic that cannot be avoided in this exhibition. The 8K heat in recent years was mainly driven by Japan, because the 2020 Tokyo Olympics determined the use of 8K broadcast standards early in the morning. Previously, NHK also stated that it would achieve 8K resolution TV signal coverage by 2020, which would help to quickly open the 8K market.
It is understood that as early as November 2013, BOE has launched 8K ultra-high definition display technology and has been in the leading position in the world. Recently, BOE once again demonstrated 8K LCD monitors at FINETECH JAPAN, hoping to enter the Japanese market to meet business opportunities such as the 2020 Tokyo Olympics. The Japan Semiconductor Energy Research Institute has brought even more surprises to the industry - 8K OLED.
Ouyang Zhongcan, an academician of the Chinese Academy of Sciences, pointed out that it is feasible to broadcast through 8K. We have used local or cable services, broadband services, 5G mobile technology, satellite technology for broadcast and signal transmission, and applications in non-TV fields. 8K technology will have a wide range of applications, including digital signatures, education, cinemas, digital museums, medicine, broadcasts, etc., as well as 8K applications in the home, security and locomotive sectors. 8K technology can also be used in the medical industry. There are already some medical projects in Japan that use 8K technology, such as laparoscopic diagnosis, telepathological diagnosis, or machine-assisted surgery.
Ouyang Zhongcan also said that the 8K ultra-HD industry will usher in rapid growth after 2018. It involves many industries and huge market space, and has become the focus of attention and investment hotspots of all countries in the world. China's 8K ultra-high-definition industry has a global leading position in the display and content transmission links, but the content shooting and content production links are relatively lagging. The imbalance of industrial chain development restricts the development of the industry. The 8K industry top-level design should be carried out as soon as possible to integrate resources and pilot projects. Breakthrough, will make 8K a high-end advantage industry in China.
VR and the Internet of Things are new opportunities
With the advent of the VR boom, higher requirements are placed on the display, especially for OLED displays, because LCDs cannot meet the high refresh rate requirements of VR. If the evaporation process is utilized, the resolution of the OLED display is greatly increased. At present, VR helmets generally have obvious screen window effects due to insufficient resolution.
This is a new challenge for panel makers and a new opportunity. Silicon-based OLEDs have certain advantages in resolution, so silicon-based OLEDs have also attracted the attention of many panel manufacturers. Some manufacturers also specialize in layout of silicon-based OLEDs. In short, VR has opened up a new market for panel makers.
But the VR market is only a small part of the panel market, and the IoT market is the future of panel makers. At the show, many manufacturers exhibited IoT solutions based on the display. In order to adapt to this big trend, BOE exhibited a comprehensive solution for transparent display of Internet of Things, such as transparent refrigerators and IoT windows, in the exhibition area. At the same time, 98-inch 4K super was created for commercial and professional displays such as digital signage and public display. HD vertical screen.
According to reports, the smart refrigerator exhibited by BOE is equipped with the transparent display system of the Internet of Things, which supports personalized customization. Users can customize weather, recipes and other life information on the refrigerator door. Ordering shopping, also has video interconnection, health management and other functions, and can be shared with mobile terminals through BOE cloud storage. In addition, the IoT transparent display is more energy-saving and environmentally friendly, and its power consumption is only one tenth of that of ordinary LCD screens. At the scene, many visitors showed great interest in the product and frequently experienced its interactive functions.
The IoT transparent display overall solution applied to the smart refrigerator uses the BOE cloud service as a platform to integrate the technical foundations of cloud computing, sensing, artificial intelligence and big data. The IoT transparent display overall solution was patented in Japan at the end of August 2016. It has been applied in the field of luxury brand store window display, Ginza high-end restaurant, aquarium, financial industry, medical field and other commercial fields and home services. .
