摘要： An organic compound having a naphtho fluoranthene core and a hetero aromatic group bonded to a specific position of the naphtho fluoranthene core, an organic light-emitting diode and an organic light-emitting device including the compound are disclosed. Since the organic compound has a narrow Stokes Shift between an absorption wavelength and an emission wavelength, the organic compound has a broad overlapped area between its absorption peak and an emission peak of a delayed fluorescent material, and therefore it can emit blue light with high color purity. It is possible to manufacture an organic light-emitting diode (OLED) and an organic light-emitting device that enhance luminous efficiency and color purity using the organic compound.

摘要： An organic light emitting diode including at least one emitting material layer, which includes a host and a dopant and at least one exciton energy control layer disposed adjacently to the at least one emitting material layer and an organic light emitting device having the same is disclosed. The at least one exciton energy control layer includes an organic compound that has excited state singlet and triplet energy levels lower than excited state singlet and triplet energy levels of the host. The organic light emitting diode can enhance its luminous efficiency and its luminous lifetime by incorporating one or more exciton energy control layers.

摘要： 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.
