Creating highly efficient stretchable OLEDs with nanowavy structures for angle-independent narrow band emission

npj Flexible Electronics
Stretchable organic light-emitting diodes (SOLEDs) have been the challenging class of OLEDs as they have limited processability to fabricate a design that can withstand external deformation.

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.

Types Of Organic Light-Emitting Diode (Oled)

, 2016
An organic light-emitting diode (OLED) consists of several semiconducting organic layers sandwiched between two electrodes, at least one of them being transparent. OLEDs can provide brighter, crisper displays on electronic devices and use less power than conventional light-emitting diodes (LEDs) or liquid crystal displays (LCDs) used today.
