ITO-free top emitting organic light emitting diodes with enhanced light out-coupling

, 2014
Bottom emitting organic light emitting diodes (OLEDs) can suffer from lower external quantum efficiencies (EQE) due to inefficient out-coupling of the generated light.

Inverted device architecture for high efficiency single-layer organic light-emitting diodes with imbalanced charge transport

Nature Communications
Many wide-gap organic semiconductors exhibit imbalanced electron and hole transport, therefore efficient organic light-emitting diodes require a multilayer architecture of electron- and hole-transport materials to confine charge recombination to the ...

End-emitting nano organic light emitting diodes (OLEDs) with directional output

Nanophotonics, 2020
We report a new strategy for the design of organic light emitting diodes (OLEDs), where nanoscale OLEDs are fabricated into a large-area periodic array with their emission propagating along the active layer and being coupled out through the end facets. A
