OLED microdisplays are increasingly establishing themselves in consumer-ready wearables and data glasses. In order to meet the requirements for higher efficiency, higher contrast, and higher resolutions in these applications, Fraunhofer FEP scientists have developed a new micropatterning approach for OLEDs on silicon substrates.   This might eliminate the use of color filters and shadow masks in the future and allow full-color displays to be developed by means of a new process. An increase in ...
