OLED R & D production heat should be concerned about the development of standards

The development of OLED industry needs to solve three problems: first, reduce costs. Second, improve life expectancy, which is an important step in the OLED TV and other consumer durable market. Third, to strengthen the application development, especially in the field of mobile phones and mobile display, strengthen cooperation with upstream and downstream industries, give full play to the technical advantages of OLED.

At the beginning of this year, the U.S. consumer electronics show, we saw a lot of OLED (organic light-emitting diode) products from 15 inches to 32 inches, in 2009, OLED seems to be entering a period of rapid development. Data show that OLED large scale research and industrialization are constantly warming, although the impact of the international financial crisis, but the pace of research has not stopped and changed. At present, life and cost is still a relatively large problem in the development process of OLED. Experts said that the current urgent need to solve the problem of OLED is to reduce costs, improve life, enhance application development.

Technology development and Application

From the past 5 years, the development process of OLED, OLED technology continues to advance, but the industry is indeed spiraling. Zhejiang tricolor Instrument Co., Ltd. chairman Mou Tongsheng believes that the factors related to the development of OLED industry and has three aspects: one is the development of OLED technology, the two is the development of terminal application industry, and the three is LCD (liquid crystal display) industry competition.

South China University of Technology Research Institute of Polymer Optoelectronic Materials and devices, Xu Wei in an "China electronic newspaper" interview with reporters said that the current domestic OLED technology development is very hot, whether it is the development of enterprises and research institutions are very concerned about OLED technology. The rise of Chinese OLED boom, larger events are weixinnuo OLED large-scale production line. In 2008, OLED weixinnuo production line put into operation in the fourth quarter, quickly enter the market at home and abroad, the products involved in the field of application of portable consumer products, instrumentation, medical equipment etc..

Senior Consultant of Huambo springs in an "Chinese weixinnuo electronic newspaper" interview with reporters, the last two years, OLED technology has been greatly developed, especially the large size OLED (AM OLED) active driving technology has achieved industrialization, which is to promote the further development of OLED has a decisive role. From the beginning of the second half of 2007, technical results began to show, using OLED technology, especially AMOLED products began to appear in the market.

OLED is a new technology, the development of time is relatively short, there are many immature technology, in addition to the scale of the industry did not rise, resulting in high cost. In 2005 -2006 OLED into the bottom, the price is the direct cause of the liquid crystal display, the application OLED in trouble, many in the OLED technology development and application of business failures, but after all is the cause of the technology. In the second half of 2007, OLED applications have been raised, mainly due to technical reasons, in recent years, more mature OLED technology. But we should see that, after all, OLED is still a new technology, the future development should also belong to the technology driven rather than market driven.

2007 SONY launched 11 inches OLED TV, the industry is an exciting news, therefore, it can be said that in the second half of 2007 began to enter the spiral OLED. The DisplaySearch2008 report in December, is expected in the next 7 years, OLED monitor shipments compound annual growth rate will reach 20%, is expected in the next 7 years OLED TV shipments CAGR will be as high as 126%. AMOLED is very suitable for the performance of the TV, in 2008 only SONY OLED TV sales in the market, in 2009, SONY, Samsung, LG, etc. have launched OLED TV, the size is greater than 11 inches. Electrical Limited by Share Ltd chief engineer Liu Weidong in an interview with Hisense "Chinese electronic newspaper" interview with reporters, due to flat-panel TV from 2007 began to thin the trend, SHARP, Hitachi, SONY, Samsung, Matsushita have launched ultra-thin display or LCD or plasma TV, and in the thin, OLED is a the technology on the natural advantage, and OLED represents flat display of the latest technological achievements, this is the year of CES (Consumer Electronics Show) on SONY, Samsung and LG have presented a variety of reasons 15 inches -32 inch OLED tv. Due to the current stage of OLED in 7 inches or more of the product and LCD cost or price gap can reach several times, low yield problems are not completely resolved, so the real market is also facing great difficulties. "Liu Weidong thinks.

Improve the yield is the key to reduce costs

As we know, cost and life are the main problems of OLED. The cost can be reduced, the yield is a very critical factor, Xu Wei said that at present, the yield of OLED was also significantly lower than LCD.

Wan Boquan believes that the cost of the problem can not simply from the volume, the cost and yield as well as market demand has a great relationship. Big problems in the process of the development of life is OLED, Xu Wei said, the life and the material, have a great relationship with the organic light emitting material itself, the data show that the SONY OLED display life can reach 30 thousand hours, but this is only laboratory data.

Bai Fenglian, a researcher at the Institute of chemistry, Chinese Academy of Sciences, said, OLED technology in progress, both in terms of material or technology, there is a certain breakthrough, the development of OLED now still have a bright future. Tsinghua University Professor Yu Yu stressed that at present, China's large number of R & D and industrialization projects are basically passive OLED (PMOLED), passive applications are very limited
