Achieving high-luminescence organic light-emitting devices(OLEDs)with narrowband emission and high color purity is important in various optoelectronic fields.Laser displays exhibit outstanding advantages in next-generation display technologies owing to their ultimate visual experience,but this remains a great challenge.Here,we develop a novel OLED based organic single crystals.By strongly coupling the organic exciton state to an optical microcavity,we obtain polariton electroluminescent(EL)emission from the polariton OLEDs(OPLEDs)with high luminance,narrow-band emission,high color purity,high polarization as well as excellent optically pumped polariton laser.Further,we evaluate the potential for electrically pumped polariton laser through theoretical analysis and provide possible solutions.This work provides a powerful strategy with a material-device combination that paves the way for electrically driven organic single-crystal-based polariton luminescent devices and possibly lasers.
