Abstract: An organic light emitting diode including a plurality delayed fluorescent materials with specific energy levels and an organic light emitting device including the diode is disclosed. When the plurality delayed fluorescent materials with specific energy levels are applied in an emitting material layer, it is possible to minimize the energy loss or exciton quenching during luminous process and to prevent the diode from reducing life span caused by the exciton quenching. When the emitting material layer includes other luminous material having a narrow FWHM, the organic light emitting diode can enhance its color purity.

Abstract: The present disclosure relates to an organic light emitting diode including an emitting material layer that has a host and two different delayed fluorescent materials whose energy levels are controlled and an organic light emitting device including the diode. Exciton energy is transferred from a first delayed fluorescent dopant to a second delayed fluorescent dopant, which has singlet and triplet energy levels lower than singlet and triplet energy levels of the first delayed fluorescent dopant and a narrow FWHM (full-width at half maximum) compared to the first delayed fluorescent dopant so that efficient light emission can be realized.

Abstract: An organic compound, an organic light emitting diode including the compound, and an organic light emitting device including the organic light emitting diode are disclosed. The organic compound may include a fused hetero aromatic moiety having a p-type property and an aza-acridine moiety having an n-type property bonded to the fused hetero aromatic moiety via an aromatic or a hetero aromatic linker. The organic compound has relatively high energy level since it includes plural fused hetero aromatic rings. Holes and electrons can be recombined in an emitting material layer in a balanced manner since the organic compound has a bipolar property. The organic light emitting diode and the organic light emitting device including the organic compound have enhanced luminous efficiency and luminous lifetime.
