Feel the Light: OLED with touch function

10.10.2008
Organic Light Emitting Diodes (OLED) is one of the most promising lighting technology for future lighting solutions.

The OLED technology is the first real area light source technology in history. It overcomes traditional restrictions by point source lighting technologies (e.g. light bulbs or LED). Their features could be the starting point for highly efficient homogenous area light sources.

Beside the area aspects, OLED shows also the possibility for innovative light sources, e.g. structured light sources for signage, color-variable, transparent and flexible light sources. At the Plastic Electronic 2008 show the Fraunhofer IPMS presents for the first time an important innovation in OLED lighting: the worldwide first interactive touch controlled flat light source. Based on the fact that OLED is a cold light source, touching control is a safe operation.

“The touch function generate a completely new feeling of light. It´s like magic: turn on the light simply by a hand movement.” noted Jörg Amelung, head of business unit of organic materials and systems at the Fraunhofer IPMS.

Switching and dimming the light could be easily controlled by a hand movement, which overcomes the traditional controller function. Normally, the implementation of touch functions requires additional touch foils on the top of the devices. The new developed touch function requires no additional hardware, because the OLED itself is used to read out the touch signal – that´s the breakthrough, reached by the Fraunhofer IPMS.

In nearly every OLED this touch function could be implemented based on an for this purpose optimized readout circuit. This fact reduces the costs for the system and don´t influence the OLED efficiency.

Im Focus: Giant Magnetic Fields in the Universe

Astronomers from Bonn and Tautenburg in Thuringia (Germany) used the 100-m radio telescope at Effelsberg to observe several galaxy clusters. At the edges of these large accumulations of dark matter, stellar systems (galaxies), hot gas, and charged particles, they found magnetic fields that are exceptionally ordered over distances of many million light years. This makes them the most extended magnetic fields in the universe known so far.

The results will be published on March 22 in the journal „Astronomy & Astrophysics“.

Galaxy clusters are the largest gravitationally bound structures in the universe. With a typical extent of about 10 million light years, i.e. 100 times the...

Im Focus: Tracing down linear ubiquitination

Researchers at the Goethe University Frankfurt, together with partners from the University of Tübingen in Germany and Queen Mary University as well as Francis Crick Institute from London (UK) have developed a novel technology to decipher the secret ubiquitin code.

Ubiquitin is a small protein that can be linked to other cellular proteins, thereby controlling and modulating their functions. The attachment occurs in many...

Im Focus: Polymer-coated silicon nanosheets as alternative to graphene: A perfect team for nanoelectronics

Silicon nanosheets are thin, two-dimensional layers with exceptional optoelectronic properties very similar to those of graphene. Albeit, the nanosheets are less stable. Now researchers at the Technical University of Munich (TUM) have, for the first time ever, produced a composite material combining silicon nanosheets and a polymer that is both UV-resistant and easy to process. This brings the scientists a significant step closer to industrial applications like flexible displays and photosensors.

Im Focus: Researchers Imitate Molecular Crowding in Cells

Enzymes behave differently in a test tube compared with the molecular scrum of a living cell. Chemists from the University of Basel have now been able to simulate these confined natural conditions in artificial vesicles for the first time. As reported in the academic journal Small, the results are offering better insight into the development of nanoreactors and artificial organelles.
