Tsinghua University Qiu Yong R & D team to fill the gaps in China's OLED industry

As a new generation of light-emitting display technology, OLED (organic light-emitting diode) with its ultra-thin, energy saving, high resolution, vivid color and other advantages, known as the "dream display".

In 1980s, the early appearance of the OLED technology, for China's electronic information industry to bid farewell to the lack of core less screen, out of the introduction - elimination - the introduction of quagmire has brought a historic opportunity. Tsinghua University, Dr. Qiu Yong led the research team has made a number of major breakthroughs, so that the dream show in the real application shine. "Organic light-emitting display materials, devices and process integration technology and application" project, won the 2011 national technology invention award.

Professor Qiu Yong is the vice president of Tsinghua University with a deep imprint in Tsinghua, 1983 was admitted to Tsinghua University Department of chemistry learning, from undergraduate has been read to, after graduation he became a teacher.

In 1996, Qiu Yong came into contact with OLED and immediately became interested in the technology. In Qiu Yong's view, OLED provides a huge space for academic research and industrial development opportunities. Soon, Tsinghua University set up a OLED project team.

"I hope to develop Chinese core technology with independent intellectual property rights and realize the industrialization, change the Chinese display industry from CRT (cathode ray tube) to LCD (liquid crystal display) era has been the status of heteronomy. According to Qiu Yong introduction, the research team has introduced a variety of professionals in the field of expertise, a breakthrough in the study of the project in the presence of interdisciplinary dilemma, to solve the basic problems of OLED materials and devices. In 2001, Qiu Yong founded the weixinnuo company, product technology integration and production technology development through the enterprise research and development platform.

Under the leadership of Qiu Yong, Tsinghua established a laboratory research team composed of teachers, postdoctoral and graduate students of Tsinghua University. In weixinnuo company, by researchers and engineers set up R & D center team. Two R & D team has a division of labor, close interaction, so that the basic research and development and application of technology to achieve a seamless connection, and gradually formed a business as the main innovation, school and enterprise closely integrated innovation mechanism.

After more than and 10 years of continuous research, the OLED project has achieved a major breakthrough: the invention of multiple active metal precursor electron injection materials, reduce the injection barrier; the development of long life, high temperature resistance, anti interference device structure, and high purity materials, high precision fabrication technology, to solve the long-standing OLED, low efficiency life is short, manufacturing difficult key technical bottleneck. OLED monitor successfully applied to the "God seven" extravehicular spacesuit, becoming the world's first OLED technology will be applied to the field of space cases.

At the same time, Qiu Yong led the team has published more than 200 papers, the application of domestic and foreign patents 370, and is responsible for the development of an international standard, the national standard of two, a national military standard.

From basic research to technological innovation, and then to achieve industrialization, recalling the wind and rain over the past ten years, Qiu Yong said that the courage and confidence of independent innovation is the foundation of their success. He said, "courage comes from the ideal industry serve the country, confidence is the correct understanding of the development trend of the industry based on. "

In 2006, the global OLED industry experienced trough, major companies have died down, and Qiu Yong in calm analysis, in-depth thinking, chose contrarian. In 2008, they designed and built the first large-scale production line of OLED in Kunshan, and realized the OLED industry in china.

"Now our overall technology has reached the international advanced level. According to Qiu Yong introduction, they have successfully developed a series of more than and 30, the balance of the 300 OLED display products. Products are widely used in aerospace defense, consumer electronics, medical equipment and other fields. In 2011, our market share ranked second in the world. "

OLED is a world without end innovation, innovation of broad space in two aspects of basic and applied research, large size OLED display, OLED lighting, OLED display, OLED transparent flexible display and lighting, is a new hotspot of OLED technology development and industry development in the future. "We have been in the forefront of the field of pre technical layout. Qiu Yong said that the next step will focus on these hot spots, from the basic research and application of two angles to study more in-depth research.

As a scholar and teacher, I am most concerned about is innovation, the biggest wish is to cultivate talents. Qiu Yong said.
