OSRAM research project spawned ultra-thin OLED, large transparent OLED new technology

OSRAM Opto Semiconductors in a research project successfully developed OLED large transparent light source prototype, the thickness of only a few hundred microns. Thanks to the new technology, the organic light-emitting diode is not required to be packaged independently, and can be surprisingly thin in any design. The luminous area of the transparent sample is 210 cm2, which shows the great potential of the OLED light source, which shows that many extraordinary lighting dreams will come true one day.

Even OLED panel area of 17 x, 17 cm2, also clearly pointed out the future direction of the OLED lighting market. Large ultra-thin transparent light source is the trend. Through these samples, OSRAM Opto Semiconductors as an important milestone in the development of large ultra-thin OLED. These test samples are the results of a TOPAS research project, which is funded by the German Federal Ministry of education and Research (BMBF) funding target is a large transparent OLED module production area of 1 m2, the project will continue until 2011.

Although the module still need to further expand the area of Japan, but the prototype developed has so many extraordinary characteristics OLED. They are very slim, don't need expensive packages, depends entirely on the thickness of the substrate between the carrier material, ranged from 300 to 700 m. The research project will focus on the development of Japan after the thinner carrier material, in order to produce thinner OLED. These thin OLED module will be easier to apply to all kinds of applications, can be made into various shapes, occupies only a very small space, and can be seamlessly integrated into the design environment, will be detected only after the power is switched on. "OLED transparent and elastic OLED days for lighting solutions to add new aesthetic feeling," Karsten Heuser OLED the Department in charge of OSRAM Opto Semiconductors Germany headquarters said, "the future is expected to be integrated into OLED light screens and furniture in the room, for example, the windows are made of OLED, can adopt natural light during the day, night is big shine. The latest OLED will be held in Berlin from 29 to October 2009 in the professional lighting design conference (PLDC) on display for the participants to show the latest achievements in the development of. Through these panels, we can feel the designer can enjoy the imagination of future applications.

OLED panel does not need any structure can be reduced to become transparent, thanks to the new orientation of the new development of special electrode design, component structure and thin film technology. The light-emitting surface does not need any additional conductor path structure, and the current can be evenly distributed on the active surface, thereby generating a uniform brightness. Whether it is based on small molecules or polymer based manufacturing OLED, the new technology simplifies the manufacturing process. No matter what kind of material used in the active layer, the technology can produce color, warm white and cold white OLED. The next stage is to integrate the processes into a stable manufacturing system.

When the power is turned off, the OLED is almost impossible to detect, but when the power is turned on, the entire surface emits a very uniform light. On OSRAM Opto Semiconductors company OSRAM SIEMENS industrial subsidiary, is also one of the two largest lamp manufacturers in the world, its subsidiary OSRAM Opto Semiconductors GmbH (Germany Regensburg) to provide lighting, sensor and visualization applications of semiconductor technology solutions for its customers. OSRAM Opto Semiconductors with production line in Germany, Regensburg and Malaysia Penang, its North American headquarters in California in the United States of Sunnyvale, Asia's headquarters in Hongkong, and also has offices around the world. OSRAM Opto Semiconductors has more than 4600 employees. As of fiscal year September 2008 total sales of more than 529 million euros. For more information, please visit OSRAM-os.com.
