OLED display technology matures Changhong competing discourse right

As one of the most promising representatives of a new generation of display technology, OLED (organic light-emitting diode) has been much attention. Recently, Samsung Electronics announced its high-profile development strategy for the next three years OLED, and said that in 2009 the OLED TV production will be the first to market a 11 inch OLED TV SONY is also trying to reduce costs.

Domestic aspects, Changhong involved in the field of OLED, breaking the previous only college and edge companies involved in OLED research, without the embarrassment of traditional household electrical appliance enterprises involved. But it is undeniable that, due to the lack of prospects for the development of OLED technology can not be more than the deployment of a lot of research and development of the funds of the enterprise, so the country has not yet formed a whole atmosphere to enter the OLED.

Japan and South Korea is a leading enterprise

Before Changhong officially invested in OLED project, OLED is recognized as the most ideal and most promising new generation of display technology after the LCD and plasma, has been very hot.

Internationally, in the past two years, CES (International Consumer Electronics Show), Samsung, SONY, EPSON and other companies have demonstrated a OLED based television, which is launched Samsung 31 inch OLED tv. SONY at the end of last year also launched the world's first 11 inch OLED TV, XEL-1".

Since then, SONY, Samsung as the representative of the manufacturers have been studied OLED. The latest information is: Samsung SDI display business unit vice president, said Woo-JongLee, Samsung is expected in 2009 around the use of OLED panels on TV, laptop. And after the launch of the SONY XEL-1, it has been involved in research to reduce costs.

At home, before Changhong, OLED research can be divided into several groups: first, college, such as Tsinghua University, South China University of Technology, etc.. Two is engaged in liquid crystal and photoelectric research of some enterprises, the scale of these enterprises is relatively small. The three is the acquisition of the school, such as BOE in the acquisition of the introduction of Korean technology, including the OLED. In addition, some of the original electronic companies do not engage in, see OLED have prospects for development, but also to participate in.

But at that time, including Hisense, SKYWORTH, Changhong, TCL, etc., including the strength of the well-known domestic appliance companies, there is no clear that they want to participate in the OLED project research. The government departments in the past few years have repeatedly organized OLED technology to explore, hoping to attract the attention of domestic enterprises, but in the end little effect.

"Changhong active investment OLED industry, representing the major strategic transformation of the China color TV industry, has been out of the first generation CRT (CRT) and second generation LCD and plasma heteronomy embarrassment. "PRC, market research, marketing director Peng Yu told the" China Electronics News "interview with reporters.

Core technology doctrine"

Because OLED technology has high brightness, contrast, color performance and many other advantages, so the international market to invest heavily in R & D of the technology companies continue to increase.

"According to incomplete statistics related events Chinese electronic newspaper" reporter relates to the field of OLED, 2007, in addition to Samsung, SONY, and the following enterprises to OLED research: MITSUBISHI heavy industries announced in 2007 will begin production of OLED panels in 2009; in August 2007, LG Electronics announced, the turtle E plant has started mass production of AM (active type) OLED panel, also revealed that LG will launch a 2-3 mobile phone model using AM OLED panel; then, to get rid of SED (the surface conduction electron emission display technology) business of Toshiba also said it will invest more in R & D strength OLED. In addition, EPSON, DuPont has long coveted OLED technology.

Domestically, weixinnuo completed the OLED market entry through its own research and development way. Vice president of Beijing weixinnuo Technology Co. Ltd Huambo spring "China electronic newspaper" in an interview with reporters, at present in some areas of OLED have reached the international advanced level, a total of 171 patents. Among them, weixinnuo in OLED has completed 120 patent applications, authorized 32 items, including the core patent three field device structure, process and material, CIGNA Kunshan factory will be officially put into operation in the second half of this year.

With the weixinnuo "independent innovation" in different ways, the Changhong OLED investment project is hundred-percent "ism".

Reporters learned that the Changhong OLED project and Chengdu hi tech Investment Group Co. Ltd. jointly set up a joint venture company, the name for the Sichuan rainbow display technology Co. ltd..

Changhong planning minister Lang Fengwei said, the technology and equipment of the joint venture company wholly owned acquisition of Korea ORIONOLED company and the production line, the first phase of the project in ORION company 12 million / year (equivalent to 1 inch screen) passive OLED production line, the latter active OLED the whole process of the production line, products with 1 inch -3.5 inch active the OLED display module and the main target production capacity of 24 million pieces per year (equivalent to 1 inch screen). At the same time, the development of the production and production base of portable TV (500 thousand / year) and mobile TV (production capacity of 1 million 500 thousand units / year). "The 'ism' of the domestic color TV enterprises more feasible, independent research and development of technology has a great voice, but time and development costs are high, the risk is also great, so it's reasonable to 'take' the most realistic. "Peng Yu thinks.

Opportunities for Chinese enterprises?

Comparison on the international market, some companies in the OLED process, domestic enterprises have this understanding and research there are still significant gaps, not only because they are so simple that, such as Samsung, SONY and other companies have come up with the development of OLED
