LED, once synonymous with neon lights, has set off a technological revolution in the field of color TV. Entering 2010, LED LCD TV is the first choice for buyers. However, when LED LCD TVs have just been popularized in the market, OLEDs (Organic Light Emitting Diodes) have been identified as the next-generation flat panel display mainstream technology to replace LEDs. I believe that "At present, OLED technology is still in its infancy, and Chinese and foreign companies who have mastered the technology of OLED large-scale and high-yield, who will seize the OLED TV first."
OLED development status and application fields
Currently engaged in the commercial development of OLEDs, more than 100 manufacturers around the world, OLED can be divided into two categories according to the direction of technology development, one is Japan, South Korea and Taiwan as the representative of Kodak's low molecular OLED technology, and the other is based on European manufacturers. PLED is the main. In addition to the KODAK alliance, another polymer company based in the two groups now also cooperates with EPSON, DuPont, Toshiba and other companies to develop their own products.
Since its first commercialization in 1999, OLED has been successfully applied in many fields. In the commercial field, OLED displays can be applied to POS machines and ATM machines, copiers, game consoles, etc.; in the field of communication, they can be applied to mobile phones, mobile network terminals, etc.; in the field of computers, they can be widely used in PDAs, commercial PCs and homes. On PCs and laptops; in the field of consumer electronics, it can be applied to audio equipment, digital cameras, portable DVDs; in industrial applications, it is suitable for instrumentation; in the field of transportation, it is used in GPS and aircraft instruments.
The wide range of applications has undoubtedly promoted the development of the OLED industry. However, the updating of display technology is also inevitable. The OLED display technology is different from the traditional LCD display method. It does not require a backlight. It uses a very thin organic material coating and a glass substrate. When there is current, these organic materials will Glowing. Moreover, the OLED display screen can be made lighter and thinner, without the limitation of the viewing angle, and can significantly save power, but the organic light-emitting display technology also has shortcomings such as short service life and large screen size. Although OLEDs with better technology will replace LCDs in the future, how to overcome technical problems will become the top priority for Chinese and foreign companies. At the same time, it also determines the process of OLED application on flat-panel TVs.
China's OLED industry development process
From the perspective of the development of the TV industry, every upgrade of the industry is inseparable from technological innovation. In every industry upgrade, China's color TV industry is in a state of chasing after the wind and tired of imitating. The reason is that the lack of technology is still a key factor. In June this year, the Ministry of Industry and Information Technology announced the results of the bidding for the AM-OLED (Active Active Drive Organic Light Emitting Diode) project by the Electronic Information Industry Development Fund. The Ministry of Industry and Information Technology gave Visionox, BOE, and Hongshi 3 respectively. The corresponding financial support of the home business. The government's strong support for new flat-panel projects will become a new opportunity for China to develop large-size OLED technology. In the third generation of display technology, China's OLED industry is almost at the same starting line with foreign countries. At present, the opportunities for developing OLED industry are rare. With the joint efforts of the government, enterprises and scientific research units, the development of China's OLED industry will be able to achieve the curve beyond. It is precisely to see the prospects of the OLED industry, many places in China have begun to get involved in the research of OLED technology, and try to industrialize. According to the Consumer Electronics Research Office of the China Electronics Chamber of Commerce, there are currently OLED R&D or production bases in Jilin, Beijing, Jiangsu, Shanghai, Guangdong, Sichuan, etc., and three places are concentrated in Sichuan, Jiangsu and Guangdong. There are five OLED production line projects that have been built, under construction and prepared in Guangdong Province, namely, Shanwei Xinli small-size OLED production line, Foshan Zhongxian Technology's low-temperature polysilicon TFT (thin-film field effect transistor) AMOLED production line project, Dongguan Hong Wei's OLED display screen demonstration production line project, Huizhou Maoqin Optoelectronics AM (active) OLED optoelectronics project, Rainbow's OLED production line project in Foshan. The emphasis on OLEDs may increase the voice of Chinese companies in the industry chain, but for China's color TV industry, which has been following Japan and South Korea in product research and development, innovation and breakthrough are not easy. The "screen" defect also makes Chinese color TV companies in crisis on the road of high-cost investment in OLED layout.
Focus on Japan and South Korea, China's OLED development determines the future role
Japanese companies use Sony as an example. In 2004, Sony first mass-produced small-size, full-color OLED panels for successful use in mobile devices. In October 2007, Sony was the first to launch the 11-inch OLED TV XEL-1 worldwide. Because the price is too expensive, causing slow sales, failed to achieve the expected results, and Sony has not found a solution to reduce costs. Affected by this, Sony announced at the end of March this year to stop the production and sales of OLED TV in the Japanese market. Compared with Sony's low-key exit, South Korea's Samsung's high-profile debut is more eye-catching. Looking at the layout of OLEDs by Korean companies, they disapprove of Sony's experience in OLEDs. In their view, experience seems to be enough for them to cope with the arrival of OLEDs. Recently, Samsung made it clear that it will invest 1.3 billion US dollars to build the 5.5th generation OLED panel factory, and said that the panel factory will be put into operation in January 2011, which will launch an impact on OLED TV.
When Japanese companies opt out and Korean companies make high-profile appearances, Chinese TV companies are eager to pursue OLED TVs. In the CRT era and the LCD era, Chinese companies are catching up with Japan and South Korea. The weakness in liquid crystal display technology has led Chinese companies to rely excessively on upstream panel companies in Japan and South Korea, which has led to the embarrassing situation that Chinese companies have no goods to sell in recent years. I think that it will take time for OLED display technology to become popular on TV sets. However, in terms of OLED TVs, if technical reserves are advanced in advance, it is a proactive and long-term approach. Research on OLED technology, perhaps in the future when OLED TV is popular, Chinese color TV companies will change the role of former followers.
