    摘要: An organic light emitting diode (OLED) and an organic light emitting device comprising the OLED are described. The OLED can comprise at least one emitting material (EML) disposed between two electrodes, where the EML can comprise a first compound comprising a fused ring having boron and oxygen and substituted with at least two fused hetero aromatic group, and a second compound comprising a fused ring having boron and nitrogen. The first compound and the second compound can be the same emitting material layer or be present in adjacently disposed emitting material layers. The luminous efficiency and luminous lifespan of the OLED can be improved by applying the first and second compounds, and adjusting their photoluminescence wavelength, absorbance wavelength and energy levels.

    摘要: An organic light emitting diode (OLED) including at least one emitting material layer (EML) disposed between two electrodes and comprising a first compound including a fused hetero aromatic ring with at least one nitrogen atom and a second compound of a boron-based compound and an organic light emitting device including the OLED is disclosed. The first compound and the second compound may be the same emitting material layer or adjacently disposed emitting material layers. The OLED can lower its driving voltage and improve its luminous efficiency using the first and second compounds with adjusting their energy levels.

    摘要: An organic light emitting diode (OLED) including at least one emitting material layer (EML) disposed between two electrodes and comprising a first compound including a fused ring of boron and oxygen as a nuclear atom and a second compound including a fused ring of born and nitrogen as a nuclear atom and an organic light emitting device including the OLED is disclosed. The first compound and the second compound may be the same emitting material layer or adjacently disposed emitting material layers. The OLED can lower its driving voltage and improve its luminous efficiency using the first and second compounds with adjusting their energy levels.
