    Abstract: An organic light emitting diode comprises an emitting material layer implementing a delayed fluorescence and another emitting material layer disposed adjacently to the emitting material layer and implementing fluorescence or phosphorescence and an organic light emitting device including the diode. As exciton generated in the plural emitting material layer drops to a ground state through the luminous materials each of which has a controlled energy level, it is possible to implement excellent luminous efficiency derived from a delayed fluorescent material and improved color purity derived from a fluorescent or phosphorescent material having narrow FWHM.

    Abstract: An organic light emitting diode (OLED) and an organic light emitting device comprising the OLED (e.g., a display device or a lighting device) are described. An emissive layer disposed between two electrodes comprises an exciton control layer between a red emitting material layer and a green emitting material layer. Exciton recombination zone is distributed uniformly within the entire area of an emitting material layer and holes and electrons can be injected into the emitting material layer in balance. The degradations of the luminous materials and/or charge transporting materials caused by quenched excitons as non-emission can be minimized. The luminous lifespan of the OLED can be improved, while maintaining luminous efficiency.

    Abstract: An organic light emitting diode (OLED) is described, as well as a display device, e.g., a display device or a lighting device that includes the OLED. The OLED includes a first electron transport layer having a first electron transporting material of a benzimidazole-based compound substituted with at least one anthracenyl group, and a second electron transport layer having a second electron transporting material of a benzimidazole-based compound substituted with at least one fluorenyl group having a spiro structure. An electron injection layer and/or a charge generation layer includes a phenanthroline-based compound. The second electron transport has an electron transport material with excellent thermal stability, disposed adjacently to the electron injection layer and/or the charge generation layer, so that the OLED can maintain good luminescent intensity in an environment of high temperature and implement beneficial luminous properties.
