Diving into a new virtual world and taking part in films by eye control – all this might be possible with a new SVGA-OLED microdisplay. The Fraunhofer Institute for Organic Electronics, Electron Beam and Plasma Technology FEP has been working for a long time on the development of OLED microdisplays combining display and camera functions. The latest work will be presented by scientists at the Hannover Messe (13th – 17th April 2015, booth of TU Dresden – CFAED, hall 2, booth A38).
The world of the so-called wearables is colorful and versatile: Wrist band measuring the pulse, buttons, which indicate the receipt of e-mails with color change or glasses providing information about the environment.
Already in 2012, Fraunhofer FEP presented a pair of glasses which enables a normal perception of the environment and, at the same time, offers the possibility to get digital information projected directly into the user’s field of view, which can even be controlled by eye movement.
Thus, for example a technician is able to read a manual while working and scroll pages with his/her eyes without interrupting activities. This is possible with a so-called bidirectional OLED microdisplay, which is a display element that includes an embedded image sensor. The sensor can record the user’s eye movement with this integrated camera and thus enables an interaction with the displayed information.
A full-color OLED microdisplay has now been developed by the scientist where the display as well as the integrated camera functions have SVGA resolution (800 × 600 × RGBW).
Bernd Richter, Head of Department “IC and System Design”, where the new display has been developed, describes the new features: “The new generation of bidirectional microdisplays represents a quantum leap in many ways. All essential key parameters of the chip could be improved significantly.
This includes an increased resolution of the display and the image sensor as well as an enhanced color depth and the integration of further important components directly into the microdisplay chip. Following this the microdisplay can be operated with significantly fewer external components and thus contributes to further development of miniaturized and efficient systems.”
To ease customers the entry in these new technology the scientists offer development kits in various configurations. The new microdisplay can be transferred directly into product-specific applications. Moreover, fast and cost-efficient customer-specific adaptations and further developments towards innovative microdisplays are possible, which are based on an efficient design methodology of the Si-CMOS backplane circuit.
A part of the work was financed by the Federal Ministry of Education and Research (BMBF) (project ISEMO, funding code: 16SV3682) and by the Fraunhofer-Gesellschaft.

Physicists of the University of Würzburg have made an astonishing discovery in a specific type of topological insulators. The effect is due to the structure of the materials used. The researchers have now published their work in the journal Science.
Topological insulators are currently the hot topic in physics according to the newspaper Neue Zürcher Zeitung. Only a few weeks ago, their importance was...
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...
