OLED Polymer with Minor Defects and Simple Production for an OLED Display
Inventor(s): PD Dr. Stefan Immel, Dipl.-Chem. Serena Nickel, Prof. Dr. Matthias Rehahn, Dr. Thorsten Schwalm
Abstract: This development enables a simple coating and structuring of a carrier with an OLED polymer. As a result of this, OLED displays are easy to produce. An advantage of this development is the solvent which is saved during the structuring of the OLED polymer. This is achieved by eschewing certain processing steps. Another effect of the invention is the significant reduction of defects within the OLED polymer. A uniform aging of the different colours can thus be achieved. This offers the particular advantage that colour shifts can significantly be reduced during aging. Ageing effects can consequently be compensated to a certain extent simply by increasing the current. This therefore extends the service life of the OLED. However, the OLED’s operating life remains finite.
TransMIT is looking for cooperation partners for the further development of the invention up to routine application and/or distribution and production part- ners in Europe, the USA, and Asia.

Friction Bearing for Reducing Resonance Vibrations
Inventor(s): Dr. Athanasios Chasalevris, Dr. techn. Fadi Dohnal
Abstract: This new type of friction bearing facilitates an ef- fective reduction in resonance vibrations by using a movable friction bearing half-shell which only opens when the critical rotor speeds are passed. The degree of damping increases by enlarging the film thickness of the lubricant over the short-term; as a result, the usual additional externally applied damping means are unnecessary.
The theoretical preparations for the development of this friction bearing have been completed. The next step is to construct a prototype.
