OLED accelerated domestic production to replace liquid crystal industry gap

In the domestic color TV industry in the transition from CRT to LCD constantly on the run, alternative technologies and started a new strides industrialization process.

January 15th, reporter learned from relevant sources, provided by Tsinghua University Kunshan weixinnuo technology company OLED production line will be mass production in the second half of 2008. In the international arena, SONY has produced 11 inches OLED TV in the end of January; in this year's CES exhibition held in Las Vegas, the United States, Samsung and SONY were launched in the 31 inches and 27 inches OLED tv.

OLED (organic light emitting display) is the industry that is currently widely used in liquid crystal display replacement. The latest research report from the survey agency Display search shows that in the field of flat-panel TVs, along with the OLED technology and the life of the puzzle to crack, OLED TV in 2014 will exceed the LCD TV sales.

According to the reporter, currently in Kunshan weixinnuo, and the color of God International, Sichuan Changhong two companies are planning to build OLED panel production line.

China's technology gap

In the CRT era, the domestic color TV enterprises gained market share in the global market with the advantage of low manufacturing cost. However, in the process of the color TV industry from CRT to LCD TV, the local enterprises have not been able to keep up with the pace of industrial change because of the accumulation of technology and R & D investment. Especially since the heteronomy in the upstream LCD panel supply, local enterprises in the LCD TV market share shrinking.

Prospective on technology development makes the foreign enterprises to obtain the competitive advantage in the flat-panel LCD TV era. In the LCD TV alternative - OLED - field, foreign-funded enterprises are also in front of.

According to the reporter, in Chinese caused by OLED technology enterprises, the United States Kodak, Japan's SONY, pioneer, and South Korea's Samsung, LG and other 21 companies in 2004 to achieve a production of small and medium size OLED panel, and began to be widely used in mobile phone, MP4 automotive electronics and other fields.

Before 2007 three quarter data show that RiTdisplay and Taiwan of South Korea and Japan were among the pioneer OLED panel shipments before three, annual shipments exceeded 80 million. In the field of mobile phone screen, OLED panel shipments accounted for up to 60%. Of course, due to the shortcomings of OLED technology in terms of service life, its shipments often occur between the ups and downs.

"Although China OLED technology research and development in the early 90s began, Japanese and Korean enterprises had little difference, but in the industrialization of our country lags behind at least 5 years, by the end of 2007 there has not been a production line. Changhong deputy general manager Wu Yingjian said, Chinese enterprises also playing catch-up position in the field of OLED technology.

Data show that, compared with foreign enterprises have more than 6000 OLED patents, patent number only 100 number of domestic enterprises.

In order to avoid repeating the mistakes in the LCD era, domestic enterprises have begun to layout in OLED industry. Tsinghua University and visionox company is the domestic institutions early entry into the field of the.

According to the introduction, Tsinghua University began to study the basic technology in OLED from 1996. By the end of 2001, established by the Tsinghua University to participate in the investment of CIGNA corporation. In 2002, the company in Chinese weixinnuo built the first pilot production line in OLED, and in the second half of 2003 to achieve the OLED screen and the module of small batch production and sales, to complete the technology breakthrough.

As of now, Tsinghua University and visionox company applied for a total of 120 domestic and foreign patents, the key technology of OLED cathode technology breakthrough, also on behalf of Chinese participated in the formulation of international standard OLED.

Tsinghua University and visionox company OLED project then began to lead in the national development and Reform Commission, Ministry of information industry to industrialization. According to the latest news, at present, CIGNA Corporation factory in Kunshan basically completed the construction of production line equipment began purchasing and have been moved, the design capacity of small and medium size OLED screen 10 million, the second half of 2008 officially put into operation.

CIGNA Corporation OLED project based on independent research and development based on the technology of Tsinghua University, the industry is considered to be China's first time in the display industries rely on independent technology to achieve mass production breakthrough, marking China's new flat panel display technology in the field of independent innovation through years, from the implementation of the technology to industry transformation.

In addition, except visionox company, the color of God International and Sichuan Changhong also moves in the OLED panel production. April 2007, announced the investment of 1 billion 200 million yuan in Nansha, the annual production capacity of more than 20 million pieces of AM-OLED plant in Guangzhou, allegedly the project will be put into operation in 2008. Sichuan Changhong announced at the end of last year will invest more than 1 billion yuan in Chengdu high tech Zone to build small and medium size OLED panel production line, the project will be put into operation in the second half of 2008.

And weixinnuo rely on independent research and development of technology is different, more than the color of God and the Sichuan international technology Changhong OLED project from abroad, including Zhang Hongyong spirit international project leaders worked in Japan's SHARP and Fujitsu, it brings is the more advanced AM-OLED technology. Sichuan Changhong deputy general manager Wu Yingjian said, "Sichuan Changhong intends to invest OLED project technology, from the part of
