Highly durable organic light emitting diodes (OLEDs) were developed by extending the doping sites. The doping sites include the doping of both hole transport layer (HTL) and emitting layer (EML). To develop these devices further, a wide variety of host and dopant materials and their combination should be examined, while the detailed mechanism of the doping that results in the enhancement in device durability should be clarified.
