  • Organic compound, and organic light emitting diode and organic light emitting display device including the same
    Patent number: 11505557
    Abstract: Discussed is an organic compound of Formula 1 and an organic light emitting diode and an OLED device including the organic compound. In the organic compound, Ar1 is a heteroaryl group comprising a nitrogen atom, and Ar2 is a C6 to C30 aryl group, and R is a C1 to C10 alkyl group. The organic compound may be included in an emitting material layer of the organic light emitting diode as a host such that an emitting efficiency and a lifespan of the organic light emitting diode and the OLED device are improved.
    Type: Grant

  • Organic compound having improved luminescent properties, organic light emitting diode and organic light emitting device having the compound
    Patent number: 11401268
    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.
