On Thursday, September 7, 2017, the International TADF Symposium (organized by cynora GmbH) will take place in Frankfurt. It will be a packed one-day event with a tight focus on OLEDs based on thermally activated delayed fluorescence (TADF). The event will bring together leading industry and academia to share new results and discuss upcoming developments. You can find all the details about speakers and program on the events webpage. It is definitely a very good opportunity to get in touch with the people working on this exciting material development.
In this paper entitled ‘Transparent and color-tunable organic light-emitting diodes with highly balanced emission to both sides‘ we demonstrate transparent, two-color, stacked OLEDs that allow for balanced top- and bottom-emission. Making use of ultra thin, composite metal electrodes, this design avoids the use of ITO, such that this architecture can be transferred to flexible substrates. Careful optical design made it possible that the luminance of the device is virtually identical to both viewing directions, which is a great improvement over many earlier device layouts.
