A Simplified Organic LED
Although the efficiency of organic LEDs (OLEDs) has improved steadily in recent years, it remains challenging to manufacture the intricate, multilayered devices.
Researchers at the Institut für Hochfrequenztechnik at the Technische Universität Braunschweig, Germany, who are seeking to overcome the complex process, have created highly efficient OLEDs with only two organic layers. The result is an OLED that performs well but uses less organic material than other approaches and thus is...
