The present and future of OLED Technology

In 2008 the Beijing Olympic Games opening ceremony, a large number of the use of LED (light emitting diode) technology will be decorated magnificent opening ceremony. The bird's nest, the central floor of the LED screen, performers LED decorative lights on the body, the air rises in the LED Olympic rings, bird's Nest stadium stand on the large LED screen, etc., have become the focus of world attention.

Rapid development of science and technology. In the field of solid state lighting and display, although LED or "Lotus just buds, but a new generation of lighting and OLED display technology has developed rapidly.

Fantastic display technology

OLED (organic light emitting display) refers to the technology of organic materials under the electric field. LED is also a kind of electro - optical conversion device, but it is made of inorganic materials. Thus, OLED and LED are both different and related. Similarly, the two can be applied in the field of display and lighting. The difference is that in the field of lighting, limited by the structure, LED is a point source, and OLED is a plane light source; in the display field, LED display screen display device is composed of light-emitting diode array, to display high-resolution images, and the OLED is composed of lithography electrode substrate and the organic light emitting material with display device composed of. Can achieve high resolution image.

OLED has many advantages, such as solid state, active light emitting, high contrast and so on. It is called "fantastic display technology" by the experts of panel display industry at home and abroad". The international community attaches great importance to the new flat panel display technology. In 2005, OLED is the United States CNN (CNN) as one of the 25 major technical innovation in recent 25 years of mankind's most influential; in 2006, OLED was listed for market research company Gartner ten strategic technology third.

1997 car audio display for the first OLED product was born. As of now, the OLED display has been widely used in mobile phone, digital camera, MP3, MP4, audio, instrumentation and other small and medium size display field, will soon expand to the notebook computer display, color TV and other large size display and flexible displays. 2007, the Japanese Sony Corp launched a 11 inch OLED color TV, the first to achieve the application of OLED in the field of television, and its excellent quality features highlight the great application prospects of OLED in the field of large size display.

According to the different driving modes, the OLED display technology can be divided into two types: passive drive OLED (PMOLED) and active drive OLED (AMOLED). Compared with PMOLED, AMOLED has more advantages: AMOLED prepared by TFT (thin film transistor) graphics display substrate so as to obtain the backplane, display capacity, display quality, longer life and better more, it can realize OLED TV display. In terms of energy saving, AMOLED shows remarkable advantages, 29 inch CRT TV's power consumption is about 100 watts, 40 inch TFT-LCD LCD TV power consumption of about 200 watts, 50 inch PDP power consumption of 500 watts or more, and a 40 inch large size AMOLED TV, power consumption of 100 watts or less. But because it is self luminous, the actual power consumption will be lower. Therefore, AMOLED is considered to be one of the most promising next generation flat panel display technologies.

Countries to speed up the layout of the patent

Market research firm Displaysearch expects this year's OLED monitor output will reach $827 million in 2012 will reach $3 billion 100 million.

Now, OLED industry has formed a certain scale, the next 5 to 10 years will be the key period of development. Although the OLED technology originated in Europe and the United States, but because of the cost and the relationship between the industrial chain, the ultimate realization of large-scale industrialization of countries and regions are concentrated in East Asia, mainly Japan, South Korea, mainland China and Taiwan.

I expect that after 2008, the OLED market will have a greater development, there will be a new breakthrough in technology. In the field of small and medium size OLED market will have a big increase in the application, the main screen phone, digital cameras, PMP, portable DVD, car display, especially in the application areas such as OLED TV will have a faster development.

In commercial applications, OLED has experienced the development process from PMOLED to AMOLED. PMOLED technology is relatively simple, mature earlier. Since the 90s of last century, OLED products to PMOLED based. However, with the progress of OLED technology, AMOLED rapid development, ready to take off.

Now, many of the world's large flat-panel display companies are optimistic about the future of AMOLED, have invested heavily in research and development and industrialization, a large number of SONY, Samsung, SDI, AMOLED and other odd photoelectric products listed, to further promote the development of industry and technology AMOLED. Although AMOLED still needs to be greatly improved in terms of production process and yield, these problems will be improved and solved over time. Costs will further decline, and will gradually enhance the ability to compete with LCD.

2008, Japan and South Korea show the two major powers competing layout AMOLED. SONY, Toshiba and other 11 companies to cooperate in tackling the next generation of large-size OLED panel key technologies in order to catch up with South korea. The Japanese government will invest 223 billion 600 million yen in research funding in the next 3 years. Samsung also plans to invest $529 million, invested in the development of large-size AMOLED display.

Companies and research institutions around the world in the development of OLED technology, while speeding up the layout of the patent. In the United States, Europe and Japan Patent Office data show that as of July 2007, the relevant patent OLED technology open about 16 thousand, which accounted for 63% of Japan, South Korea accounted for about 12.8%, the United States accounted for about 12.2%, China accounted for about 7.7%, accounting for about 2% of germany. South Korea, China has strong growth potential
