Waiting for the new era OLED acceleration for LCD

First page Preface

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.

In January 15th, 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 considered to be widely used in the industry as a substitute for liquid crystal displays. The latest research report from the survey agency Displaysearch shows that in the field of flat-panel TVs, with the OLED technology and life problems 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.

In the CRT era, the domestic color TV enterprises with low-cost manufacturing advantage in the global market to obtain a certain market share. 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.

Technology research and development prospects of foreign flat-panel enterprises in the era of LCD TV to gain a competitive advantage. In the LCD TV alternative - OLED - field, foreign-funded enterprises are also in front of.

In the technique of OLED caused the attention of the enterprise China before us 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.

Data in the first three quarters of 2007, Taiwan's re Po, Samsung and Japan, South Korea, respectively, the pioneer OLED panel shipments of the top three, the 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's 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 companies have more than 6000 OLED patents, the number of domestic enterprises only more than 100 patents.

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

According to reports, Tsinghua University from 1996 began to engage in OLED based technology research. 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.

Second page SONY OLED positioning

Organic light emitting diode (OLED) is a kind of advanced display technology based on organic light emitting material and organic structure. This technology uses an unprecedented lightweight design to achieve high quality display. At the same time, organic light emitting diode (OLED) can also provide a higher contrast, brightness, full color reproduction range and fast response time, in order to achieve superior quality. In addition, due to the application of OLED is less affected by the objective situation and the environment, it attracts more and more attention and becomes the typical representative of the next generation of display technology.

SONY research organic materials in 1994, and has been committed to organic light-emitting diode (OLED) technology for practical application. In 2004, SONY's first production of small, full-color organic light-emitting diode (OLED) panels, its successful application to mobile devices. Subsequently, SONY will be positioned as the next generation of OLED display key technologies, and continue to accelerate the development of OLED technology. After more than and 10 years of research and development of OLED technology, SONY has accumulated a large number of core technologies, such as SONY's unique "Super Top Emission" panel technology, can significantly improve the OLED panel brightness and color reproduction; in addition, the scale of production of the manufacturing process to obtain experience from SONY OLED panel before mass production of small number of. In September 2007, SONY embarked on large-scale production of its independent research and development of the "XEL-1" "Panel" (Organic).

At the same time, in the process of design and manufacture of "XEL-1" in SONY, the use of a number of accumulation in its products in the development of technology, including from the "Trinitron" (Trinitron) imaging technology era formed and obtained from mobile products in the development of high density packaging technology. The application of the technology, so that "XEL-1" TV became the world's first fusion of revolutionary design and unprecedented high-quality screen OLED tv.

The introduction of "XEL-1" marks
