Organic light‐emitting diodes (OLEDs) combining low driving voltage and high efficiency are designed by employing conventional and thermally activated delayed fluorescence emitters through modulation of excitons generated at the planar p–n heterojunction region. To date, this approach enables the highest power efficiency for yellow–green emitting fluorescent OLEDs with a simplified structure.
