>> Twenty-five OLED panel lines account for 25 display technologies in the next ten to twenty years. 28th,May,2018
According to industry statistics, there are about 27 OLED panel lines in operation and already under construction worldwide, including 10 in South Korea, 1 in Taiwan, 14 in China, and a total of 25 in China and South Korea. There are only two other countries in Japan.
OLED is currently the main display technology for high-end TVs and future small-to-medium-size high-end consumer electronics products. Until there is a new type of flat panel display technology that can break through CRT displays and plasma displays in display effects, OLED display technologies will be the focus of current efforts in the industry. direction.
However, in the OLED TV technology, due to the limitations of the technology itself, only one LG is currently promoting the market. LG's OLED TV panel uses a white OLED light-emitting layer and a color filter film for color modulation. Therefore, the LCD camp has also developed a quantum dot backlight enhancement technology and a mini-LED local dimming backlight technology for its characteristics. In order to reduce the gap between LCD TVs and OLED TVs at a low cost, the market has also witnessed high prices for high-end LCD TVs and lower prices for OLED TVs.
However, with the emergence of new driver IC algorithms, coupled with the motherboard GPU also joined some of the primary neural network artificial intelligence software, effective compensation of the driver IC algorithm, LG OLED panel yield has been greatly improved, and The cost of OLED TVs has also begun to improve. In the future, as TV motherboard technology breaks through again, the price of OLED TVs will also decrease.
Different from the OLED TV panel, the OLED panel mainly for small and medium-sized displays adopts the technique of direct RGB color mixing of the RGB three-primary-color luminescent substances in display colors, so that a richer color and higher brightness than the OLED TV panel can be obtained. This feature is more appealing to consumers for smart phones, tablets, and computer monitors that watch at close quarters over a long period of time.
The patents for OLED TV panel production technology are subject to severe differences from LG. The patents for the production technology of small and medium sized OLED panels are mostly in the hands of equipment manufacturers and material suppliers. Therefore, as long as their products are purchased, they will not be used in production technology. There is a large barrier to patent restrictions. Therefore, capital investment and industrial support efforts have become the largest competition in the small and medium sized OLED panel market.
In recent years, due to the Chinese market's baptism of the rules of the global market after China’s accession to the WTO, it has become a relatively mature and regulated market economy entity. Therefore, global consumer electronics manufacturing centers are all concentrated in China. As the most important bulk purchase commodity for consumer electronics products, it is also increasingly influenced by the Chinese market environment.
However, after all, China is lagging behind the advanced countries in the new photoelectric industry based on semiconductor technology, and can only adopt the following strategies for new display technologies. Therefore, as previously mentioned, before China itself had the ability to develop new flat panel display technology products that could break through CRT monitors and plasma displays in China, China, like South Korea, focused its resources on breaking through OLED display technology. The main direction of the current industry.
With South Korea's main R & D efforts are all concentrated in the Samsung and LG companies are different, China in the breakthrough OLED display technology adopted almost all the industry enterprises to pounce on the strategy, in addition to the upstart Huike has not announced the construction of OLED panel Outside the production line, BOE, Huaxing Optoelectronics, Shen Tianma, Hehui Optoelectronics, Visionox, Truly, Rouyu, and even Yifengtai in Jiangxi Province are actively promoting their own OLED production capacity.
The positive layout of OLED production capacity in China and South Korea, in addition to its display effect can be further improved on the basis of LCD display technology, the new packaging material technology breakthroughs, but also to OLED environmental reliability, especially the temperature environment can be more Win LCD, so as to broaden the application of OLED display technology.
In addition, the most important point is that OLED is easier to implement than the LCD, light and flexible, which has a very important significance to reduce the weight and thickness of the display, while the simple realization of the flexible display, but also for the OLED display technology opened a whole new The application scenario can obtain a greater market space and promote the creative innovation and development of consumer electronic products, and serve the industry consumption upgrade.
At present, it is possible to display OLEDs with a higher display effect. However, new display technologies that are more advantageous in terms of service life can achieve only mass production of Micro-LED displays, but in ultra-thin displays, Micro-LEDs are also OLED display has a certain gap. In addition, the internal structure of the Micro-LED is more complex than the OLED, and it is difficult to achieve the same level of energy efficiency and reliability as the OLED in a short time.
Coupled with the limitations of production costs, the Micro-LED display will take a long time to optimize the technology, thus giving the OLED display an important development window.
OLED technology core, compared to the breakthrough of the process technology, more than a breakthrough in material technology, how to improve the luminous efficiency of OLED luminescent materials, limit the speed of low brightness decay, and enhance its environmental stability, is the future of the industry In the middle.
As industry resources and government policies in China and South Korea are developing display technologies and tilting toward the OLED display industry, it will surely attract global scientific research organizations and material companies to actively follow up and develop more new types of OLED display materials. come out. Once the ultra-stable OLED luminescent material or material processing process achieves a breakthrough, the new mass production technology will also quickly follow up on this basis. The OLED display technology will also replicate the brilliance of LCD display technology and serve the world for 10 to 20 years.
