Fraunhofer FEP works on cost-effective system solutions for flexible devices and presents results at Plastic Electronics 2014
A significant growth is predicted for the market of flexible devices. The topic “Wearables”, namely intelligent, wearable systems with several useful and funny features is currently one of the major discussion topics. To enjoy more comfort, exceptional designs and higher functionality manufacturers and users ask for flexible electronic devices, like displays, lighting elements or circuit boards.
Although research and development groups have already made considerable progress in this field, not all challenges could be solved so far. Various topics are subject to further development, e.g. materials, processes, machines as well as system integration.
Fraunhofer FEP provides a roll-to-roll process line which enables the application of organic materials for OLED (organic light-emitting diodes), OPD (organic photodiodes) or OPV (organic photovoltaic) on flexible substrates in one complete technology. The process includes the structuring, automatic inspection of the initial substrates, the vapor deposition of the organics and, finally, the encapsulation of the coated films or glasses.
Organic electronics certainly require flexible electrical contacts. Therefore, Fraunhofer FEP implemented an additional printing process of metal contacts for the reliable contacting of, for example, large-area flexible OLED on metal, polymer and thin glass substrates. In cooperation with printing paste manufacturers and other suppliers, e.g. machine manufacturers, adhesive manufacturers, encapsulation film suppliers, the scientists are now able to develop optimized products for required process steps under production conditions.
Dr. Jacqueline Brückner, Project Manager Surface Analysis for the roll-to-roll organic technology, says: “Our customers have different requirements to design and mechanical stability of devices. With our know-how and our process equipment we provide a unique development platform for all these demands.”
For example, there are various solutions for the device contacting. Currently, several contacting solutions with flat ribbon cable, like ACF (Anisotropic Conductive Film)-Bonding, ACA (Anisotropically Conductive Adhesive)-Bonding or ACP (Anisotropic Conductive Paste)-Bonding are evaluated.
Examples of different contacting solutions, special contacting and encapsulation layouts for the roll-to-roll OLED processes will be presented at the booth at Plastic Electronics 2014.
Beside this exhibition, Dr. Olaf Hild of Fraunhofer FEP will give a talk with the topic “Organic Electronics and Organic Photodiodes“ at Tech Arena 1, ALPEXPO on October 7th, 12:40 pm.
About Fraunhofer FEP:
Fraunhofer Institute for Electron Beam, Plasma Technology and COMEDD FEP works on innovative solutions in the fields of vacuum coating, surface treatment and processing with electrons and plasmas as well as organic semiconductors. The core competences electron-beam technology, sputtering and plasma-activated as well as PECVD high-rate coating, technologies for the organic electronic and IC/system design provide the basis for these activities.
Thus Fraunhofer FEP offers a wide range of possibilities for research, development and pilot fabrication, especially for the processing, sterilization, structuring and refining of surfaces as well as OLED microdisplays, organic and inorganic sensors, optical filters and flexible OLED lighting.
Our aim is to develop the innovation potential of the electron beam, plasma technology and organic electronic for new production processes and devices and to make it available for our customers.

Successfully transferring Industrie 4.0 into reality

In recent years, lasers with ultrashort pulses (USP) down to the femtosecond range have become established on an industrial scale. They could advance some applications with the much-lauded “cold ablation” – if that meant they would then achieve more throughput. A new generation of process engineering that will address this issue in particular will be discussed at the “4th UKP Workshop – Ultrafast Laser Technology” in April 2017.
Even back in the 1990s, scientists were comparing materials processing with nanosecond, picosecond and femtosesecond pulses. The result was surprising:...
Have you ever wondered how you see the world? Vision is about photons of light, which are packets of energy, interacting with the atoms or molecules in what...
A multi-institutional research collaboration has created a novel approach for fabricating three-dimensional micro-optics through the shape-defined formation of porous silicon (PSi), with broad impacts in integrated optoelectronics, imaging, and photovoltaics.
Working with colleagues at Stanford and The Dow Chemical Company, researchers at the University of Illinois at Urbana-Champaign fabricated 3-D birefringent...
In experiments with magnetic atoms conducted at extremely low temperatures, scientists have demonstrated a unique phase of matter: The atoms form a new type of quantum liquid or quantum droplet state. These so called quantum droplets may preserve their form in absence of external confinement because of quantum effects. The joint team of experimental physicists from Innsbruck and theoretical physicists from Hannover report on their findings in the journal Physical Review X.
“Our Quantum droplets are in the gas phase but they still drop like a rock,” explains experimental physicist Francesca Ferlaino when talking about the...
The Max Planck Institute for Physics (MPP) is opening up a new research field. A workshop from November 21 - 22, 2016 will mark the start of activities for an innovative axion experiment. Axions are still only purely hypothetical particles. Their detection could solve two fundamental problems in particle physics: What dark matter consists of and why it has not yet been possible to directly observe a CP violation for the strong interaction.
The “MADMAX” project is the MPP’s commitment to axion research. Axions are so far only a theoretical prediction and are difficult to detect: on the one hand,...
