Degradation Properties of Organic Light‐Emitting Diodes with Modified Interface Charge Density via Dipolar Doping Studied by Displacement Current Measurement

Degradation Properties of Organic Light‐Emitting Diodes with Modified Interface Charge Density via Dipolar Doping Studied by Displacement Current Measurement

Abstract Accumulated charges at the interfaces of organic light‐emitting diodes (OLEDs) often induce exciton quenching and lead to device degradation. This work delves into the correlations of the interface charge accumulation and degradation properties of tris(8‐quinolinolato)aluminum (Alq3)‐based...
