P‐157: Electrical Modeling and Numerical Simulation of Doped Multilayer Organic Light‐Emitting Diodes (OLEDs)

This work aims at explaining and predicting the influence of dye doping and space charge effects on charge carrier transport at different operating temperatures. for that purpose, current-voltage J-V characteristics for typical electrically-doped multilayer OLEDs have been simulated. The results are in good agreement with experiment.

Stable, highly efficient and temperature resistant organic light-emitting devices

Highly efficient small molecule-based organic light-emitting devices (OLED) that use electrically doped charge injection layers are presented. These structures exhibit low power consumption, long lifetime and high stability when operated at ambient temperature. It is also shown that their performances do not change significantly even when devices are stored at 90 °C for 80 days or 110 °C for 24 h. Such OLED structures thus fulfill the most severe requirements for mobile display applications.

Electrical simulations of doped multilayer organic light-emitting diodes (OLEDs) under temperature stress for high current densities

— This work aims at explaining and predicting the influence of the thickness of organic materials, dye doping, and space-charge effects on charge-carrier transport at different operating temperatures for high current densities (50 ≤ J ≤ 7000 mA/cm2). For the purpose of determining these influences, current-voltage characteristics for typical electrically doped multilayer organic light-emitting diodes (OLEDs) have been simulated. The results of the simulations concur with experimental data.
