Intrinsically Stretchable Phosphorescence Light‐Emitting Diodes With Small‐Molecule Emissive Layer

open access: yesJournal of the Society for Information Display, EarlyView.
This study demonstrates high‐performance, intrinsically stretchable phosphorescent OLEDs by blending a small‐molecule emissive system with an elastomer. To prevent short circuits arising from the spike‐like penetration of AgNW electrodes into the OLED layers, a PMMA interlayer was introduced between PEDOT and AgNW.
