23.1: High Performance and High Stability PIN OLED

Innovative PIN OLED that use a new n-doped architecture have been investigated. Good initial performances as well as good lifetimes have been demonstrated. Thermal stability of these new diodes has been greatly improved by using a new system matrix+ n-dopant. As a result, RGB diodes can sustain at least a 500 h storage period-of-time at 90 °C with minor degradation. Preliminary studies at 110 °C for at least 24 h show also very promising features for such devices.
