Popis: First-Generation OLEDs were employing bottom-emitting structures with limited efficiency and rather high operating voltage. We demonstrate a number of novel approaches which allow realizing high-efficiency OLEDs with flexible configuration and on low-cost substrates. Electrically doped transport layers play a key role to achieve these favorable properties: First, we discuss monochromic and white pin-OLED structures with very high efficiency. Then, we show top-emitting OLEDs with doped transport layers which allow to easily optimize the optical outcoupling. Finally, we report on pin-OLED with extremely long life times.
