Polaritonic OLEDs with TADF Emitters Enable Narrowband, Angle-Independent and Ultra-Efficient Emission for Brilliant Displays

Description:

Thermally activated delayed fluorescence (TADF) enables highly efficient OLED emitters. We demonstrate a strategy to narrow their inherently broad emission spectrum by creating polaritons through coupling with an assistant strong-coupling layer. This reduces the emission width from 86 nm in the reference device to 24 nm, producing angle-independent brilliant green emission near the BT.2020 standard and more than doubles the efficiency over prior polaritonic OLEDs.
