Experimental and Theoretical Approaches for Detecting Latent Lateral Leakage Current of Organic Light-Emitting Diodes

Kazunori Morimoto, Ryu-ichi Satoh, Seonghee Noh, Takayuki Miyamae

High-resolution organic light-emitting diode (OLED) displays often suffer from image quality deterioration due to lateral leakage current (LLC). We performed the detection of LLC using operando electric-field-induced doubly resonant sum-frequency generation (EFI-DR-SFG) measurements under conditions where the electric potential, formed by the …

Influence of the atmosphere on organic–organic interfacial layers and deterioration in organic light‐emitting diodes

Hirofumi Nakamura, Seonghee Noh, Miki Kuribayashi, Chihaya Adachi

Abstract The influence of organic–organic interfacial contaminants and deterioration in organic light‐emitting diodes (OLEDs) was investigated. There was deterioration of the device characteristics when atmospheric contamination was introduced to the emission site. We simultaneously observed a decrease of the maximum capacitance, Cmax, …
