Mobile phone applications in China OLED industry prospects

Institute of science and technology industry China CCID Consulting (CCID) latest report Chinese OLED industry pointed out that although the shipments and sales amount, LCD is still in the market dominant position, but the prospects for the development of OLED technology has the advantages of low power consumption is still considerable.

OLED has the advantages of simple structure, self luminous, ultra light, fast response, wide viewing angle, low power consumption and can realize the flexible display characteristics, known as the "dream display", plus the production equipment investment is far less than TFT-LCD, the major display manufacturers, has become a new generation of display the main force in the field of technology.

A mobile phone screen and MP3/MP4 panel is still the main OLED application market, the two main application areas are used for the AMOLED PMOLED panel, the market is still the main driving force from the larger size and higher order mobile phone application market. For future growth is more optimistic about the AMPOLED, the market is advancing with the promotion of technology and application of products and constantly grow and grow.

According to CCID data show that with the promotion of MP3/MP4 mobile phone and the application demand for products, OLED display screen market began to grow rapidly, from 2005 to 2008, Chinese OLED shipments reached 642 thousand, representing an annual growth of 60.5%, increased shipments on the one hand from the market demand growth, increase on the other hand from in the production capacity of manufacturers.

China's OLED industry has begun to take shape

At present, OLED panel manufacturers are mainly concentrated in Japan, South Korea, Taiwan, the three regions. With the Samsung SDI launched the world's first active matrix OLED (AMOLED) Sony panel, and launched 11 inch AMOLED TV, Japan, South Korea, Taiwan and other manufacturers in the OLED market competition more and more strong, but also has a better competitive position in AMOLED. In addition, including LG Display, odd crystal, TMD and Samsung electronics manufacturers, have accelerated the pace of AMOLED technology development.

OLED industry has been highly concerned by the Chinese government, supported by the Ministry of industry and information technology, mainland China's OLED research and development has made breakthrough progress. In October 2008, Tsinghua University was established by the successful completion of the first Chinese weixinnuo mainland OLED mass production line in Kunshan, the small size of the OLED display screen.

By the end of 2008, the mainland China mainly in Kunshan, O Nobutoshi, Sichuan etc. irisopsia weixinnuo enterprises engaged in small size OLED production. China's first AMOLED industrialization plan was officially launched in November 7, 2008 in the South China Sea, Guangdong, Foshan. The first phase of the project invested 500 million Hong Kong dollars, the construction of a number of AMOLED display screen production line, plans to produce an annual output of 50 million inches full color OLED display screen 2.

The two or three phase of the scheme will gradually increase, the construction of the fifth generation production line, in the production of 26 inches below the size of full-color AMOLED display screen; the future will be the construction of the eighth generation TFT-AMOLED production line AMOLED display screen, television can be large and medium size manufacturing. The plan is to allow the first production line of 15 inch OLED screen to be put into production in September 2009.

Industry chain needs to be further improved

Because the OLED technology is a capital intensive industry, the information industry is the front-end technology, the relevant departments of the state need to stand in the height of strategy for the overall planning of the OLED industry, the pooling of resources, strengthen independent innovation, guide and encourage enterprises to join the OLED industry chain and to give financial support, the ability to form sustainable development.

But for now, although China has a certain OLED industry base, but the industry chain is not yet available. China does not have a complete set of OLED production equipment manufacturers, key equipment and complete sets of equipment, such as the system of technology are in Japan, South Korea and European companies in the hands of. ITO glass, lithographic glue, and getter for encapsulation of UV curing adhesive and other raw materials, there are different degrees of similar problems.

Due to the development of China's TFT technology is relatively backward, the panel process technology is weak, production management experience is not enough, so in the production process of AMOLED development is more difficult. In addition, China's capital market is not mature enough, the narrow financing channels. The role of the state in basic research, industry standards, industrial resources integration has yet to be strengthened, while the lack of OLED industry production, development and management personnel, these are the weaknesses of China's OLED industry.

At present, the world has a number of companies engaged in the design and production of OLED driver IC. OLED active drive panel is subject to high price, silicon materials and organic materials, such as poor matching restrictions, become the bottleneck of the development of the global OLED industry. China can only be imported from abroad to drive IC; in large size and color screen technology due to the relatively backward equipment conditions, the relative lack of capital investment, there is a big gap with foreign development.

These problems have restricted the development of China's OLED technology to a certain extent. In the aspect of patent, patent basic small molecule OLED material and structure is mainly in the hands of the U.S. and Japanese companies such as Kodak Idemitsu basic patent; PLED polymer material and structure is mainly in the hands of the British and American companies such as CDT DuPont; in the drive, Japan's SANYO, Sharp, SEL, Eldis, South Korea's core patent Samsung, LG and Taiwan all have a certain amount of.

Overall, the domestic OLED is still in the initial stage, all materials and accessories such as IC drive, almost upstream of conductive glass, glass packaging, organic materials, precision MASK, need to buy from Japan, Korea and other places; and
