[Source: "High-tech LED-technology and application" April issue ] Recently, the Electronic Information Product Management Department of the Ministry of Industry and Information Technology revealed that the government is providing financial support for technology development to support the development of the OLED industry and accelerate the expansion of small and medium-sized OLED panels. Production scale and promote the development of large-size OLED panels.
This OLED trend that has spread to China seems to have long been a symptom at the beginning of this year.
At the beginning of the 2012 International Consumer Electronics Show in Las Vegas, South Korea, Samsung Electronics and LG exhibited their newly developed OLED flat-panel TVs.
Recently, the "Samsung v. 11 former employees leaked OLED technology case", which has been raging, has once again exposed the competitive situation of the OLED industry.
It is understood that Samsung currently accounts for 99% of the global OLED panel supply and is in an absolute monopoly position. At the same time, Samsung is still acquiring a large number of patents. After Kodak’s bankruptcy, Samsung took the opportunity to acquire the OLED core patent owned by Kodak.
An industry insider said in an interview with the media that there are three major obstacles to OLED industrialization: First, it is difficult to find experts with mass production experience, Samsung is very strict; second, equipment, Samsung holds a lot of Korean equipment factories, buys in China There are also restrictions on equipment; the third is that the materials are in the hands of Americans and are exclusively supplied to Samsung.
"OLED industrialization is much more difficult than PDP and LCD. Many equipments need to be customized. The precision of the plant is higher, and the materials and products are closely combined. For example, the MC chip of Samsung AMOLED needs to be used in one-to-one correspondence with the product. Therefore, There are many know-hows in OLED manufacturing."
At the moment, in addition to Korean manufacturers, the joining of Japanese and Chinese Taiwanese companies has made this war without smoke more confusing.
Matsushita Group recently announced plans to invest 30 billion yen to research and develop OLED panel mass production technology. At the same time, it will accelerate the research and development of large-size household and commercial OLED TV products, and strive to be listed after 2013.
The addition of China's Taiwanese panel giant AUO has also made the OLED cost high and difficult to popularize. As the world's second panel manufacturer of mass-produced AMOLEDs, AUO and Sony Japan are very close. The two sides announced that they will have closer technical cooperation and capacity sharing in the future. It is expected that the large-scale OLEDs of 32 inches or more will be put into production on the 6th generation line at the end of the year, and it is expected that the cost competitiveness will not lose LCD panels after two years.
We turned our attention back to China.
At present, many companies and universities in China can make OLEDs. One industry insider revealed that the question is whether high quality and high yield can be achieved, and 100 pieces of success or 99 pieces are successful.
For how to introduce talents, a domestic display company advocates a “detour strategyâ€. "Our experts will not dig directly from Korean companies. Generally, these people are taught in the university for one year, and then they are introduced. Our Korean engineers here, many of them have done both in Samsung and LGD, and the talents flow here. A line is very common."
They previously acquired a Korean company, while supporting the LCD production line, there is also a group dedicated to OLED research and development, and responsible for training, many domestic engineers have been sent to South Korea for training. “We walked on multiple legs, except for Korean engineers, Japanese engineers, Taiwan engineers, and university professors from mainland China.â€
In addition to being used for display panels, the use of OLEDs in illumination sources is also controversial.
In August last year, a new research report from scientists at the University of Utah was published in the journal Nature Materials. The report shows that OLEDs achieve high luminous efficiency is not as easy as imagined. It was previously thought that OLED can convert 63% of its electrical energy into light energy. It seems that the photoelectric conversion rate of OLED is only 25%.
Recently, however, a research team led by a professor at Kyushu University in Japan has developed OLED materials with a luminosity of 86%. The new material not only does not use precious metal ruthenium, but its energy state suitable for organic molecular luminescence is greatly increased from the ordinary 25% to 86.5%.
The advent of this new type of OLED material has also led the industry to look forward to the development of OLEDs for low-power TVs and LED lighting.
