OLED: investment and increase market attention cited

Since last year, the domestic and foreign OLED (organic light emitting display) technology and product innovation, OLED once again caused concern to the industry, the domestic enterprises for production or expand production are actively preparing, all kinds of electronic products is also rising to the demand of OLED display device. With the rapid development of industry and the increasing application demand, OLED attracts more and more enterprises and investors.

Increase investment

In September this year, Guangdong formally launched the Guangdong organic light-emitting display (OLED) industrial technology research institute. It is understood that for this project, Guangdong province will arrange 220 million yuan to support the research institute to carry out key materials, OLED equipment and technology research projects, and plans within 3 years to produce the 370mm * 470mmOLED screen production line and relevant equipment. The reporter learned from the parties concerned, the Institute will set up a management office, equipment research and development center, material technology research and development center, technology support center 4 departments, Dongguan Anwell digital Machinery Co. Ltd., Dongguan Caixian organic luminescence Technology Co Ltd, Zhongshan University and South China University of Technology were responsible for equipment research and development center, material technology, technology R & D center application support center operations. Dongguan, Dongguan Anwell digital Caixian organic light emitting display is mainly responsible for the specific implementation of the project breakthrough technology and equipment.

Domestic investment in OLED projects at the same time, foreign investment is also increasing and promoting production plan. In July this year, there are reports that MITSUBISHI heavy industries will plan to enter the OLED market. In an interview, the reporter learned that MITSUBISHI heavy industries said it would start offering OLED panel samples this year, if the demand is strong, it may also start mass production. MITSUBISHI heavy industry is scheduled to start production in 2009, the fastest possible development of production samples this year.

There is news that in August this year, LG Electronics ", the turtle E factory has started AM (active) production" OLED panel, LG electronics said the upcoming "using LG electronic AM OLED panel 2 ~ 3 mobile phone model". In the OLED business, LG electronics is currently in Kyungpook Gumi E1 factory has 2 production lines. It is understood that the mass production of A production lines, the scale of the annual production of 1 million 200 thousand inches of 2 level products.

In addition, SONY and Toshiba and other companies are also investing in the development of OLED technology. OLED technology can produce bright and colorful images, and do not need to be backlit, such as LCD display, which can achieve ultra-thin size, but the high contrast panel prices more expensive. The market is a double-edged sword, huge investment and R & D costs make this technology progress is slow, and the high profits of the company, this may be the cause of the OLED market ups and downs.

Material process is the bottleneck

Factors affecting the rapid development of OLED in addition to investment and technical problems. OLED to the rapid development, which needs to solve the technical bottleneck? Reporter learned that the technical bottleneck of the rapid development of OLED, is still a luminescent material, especially blue material life, the fourth generation production equipment and the production cost limit of several old story of the bottleneck.

However, according to Reuters reports, Toshiba Matsushita Display announced at the end of 2009, the first to invest in Japan to enlarge the size of the commercialization of OLED tv. Thus, it is estimated that TMD must master the necessary mature technology, is sure to solve some of the basic problems plagued OLED within two years. If so, the future of OLED industrialization is very good. Of course, do not rule out the possibility that the above information is the other commercial speculation.

For the problem of high production costs, in fact, the main production process problems. Professor Wang Jian School of materials science and engineering South China University of Technology Polymer Optoelectronic Materials and devices research explained that for small molecules, the vacuum evaporation process, resulting in some problems: the first is to use large size substrate, the production line from the two generation line of glass substrate, 370mm * 470mm second is not continuous; production, warehouse cleaning and evaporation need regular maintenance, mask and evaporation materials need timely replacement and filling materials; third is expensive, in the production process of large losses; fourth yield is not high; the fifth vacuum evaporation energy consumption.

OLED in order to break up the panel industry, the urgent need to break through the above various production processes. In addition, the good product realization of large size substrate and large screen OLED products in the mass production, high rate, and OLED and LCD must be a breakthrough in the panel industry meet as equals before the problem.

OLED applications more widely

At present, the theoretical research of OLED is mainly concentrated in the United States, the late stage of the process, equipment, materials and other industrial research in Japan, South Korea, China's enterprises.

At present, the application of OLED is still very wide, small size of the mobile display, to this year's Japanese Sony27 inches and TMD20.8 inches of TV products are covered. In addition, OLED is currently the world's only can be used as a display and lighting products.

TIC Italy Denuo Technology Consultants Ltd. Pang Chunlin believes that if OLED can solve the problem of life and cost, improve the price structure, then, as in the same display and lighting industry products, flexible display, with its incomparable low power consumption, high brightness and light uniformity etc., its commercial application prospects is not china.

Beijing weixinnuo R & D center director Gao Yudi think, in terms of OLED applications, the application of OLED main market
