BMG MIS and Fraunhofer COMEDD present first results of the project So-Light

Date Announced: 01 Oct 2012 The possible use of Organic Light-Emitting Diodes (OLEDs) in special fields of application has been investigated by a consortium of eleven project partners within the project „So-Light“ (funded by the Federal Ministry of Education and Research BMBF). Now, first exhibits are available and will be presented at the Fraunhofer COMEDD booth at the Plastic Electronics 2012 show for the first time.The project partner BMG MIS is manufacturer of large area display systems. There is high interest in display systems with minimum installation depth. Since OLEDs can be evaporated on very thin glass, they offer a high potential for backlight illumination for LCD-based systems. Now the availability of large area and homogeneously emitting OLEDs enables ultrathin LCD-OLED-compounds as basis for modular installations of large area LCD display systems.In contrast to conventional backlight illumination, reflector- and fiber optic components will be no more necessary in those modular systems and thus the system design simplifies considerably. Furthermore OLEDs create a very comfortable and homogeneous light.Fraunhofer COMEDD developed and manufactured appropriate OLEDs for those displays together with BMG MIS. The first technology demonstrator, which shows the principle of the LCD-backlight illumination, will be presented at the Plastic Electronics show 2012.The demonstrator is backlighted by three tiled OLED-modules with the dimensions of 300 mm x 100 mm each. Due to the small total installation depth of 30 mm, it achieves a pixel brightness of 350 cd/m², which is absolutely sufficient for indoor applications. In the long term the further development of the current OLED area light sources to a single, coherent and maximized area (ideally matching the size of the LCD) offers potential for installation depths of less than 10 mm. These display systems can be used e. g. in passenger information systems in public transportation, in central building control systems and many more applications. Dr. Konrad Crämer, head of the department for organic technologies, looks ahead: “Fraunhofer COMEDD was able to produce the OLEDs for the backlight illumination of the LCDs within the project. In order to achieve even thinner systems, we are intensifying our work on the manufacturing of OLEDs on foils, which will be flexible as well.”The project partners would like to thank the Federal Ministry of Education and Research for the support of the project So-Light (project reference number 13N10533).Further OLED-exhibits, such as interactive data eyeglasses with OLED microdisplays, a makeup-mirror illuminated by OLEDs (in cooperation with HELLA within the project So-Light) and dynamic OLED lighting will be presented at the Fraunhofer COMEDD booth.
