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 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 device (e.g., a display device or a lighting device) is described, which includes a substrate; and an OLED over the substrate, the organic light emitting diode comprising: a cathode; an anode over the cathode; and an organic light emitting layer including a first emitting part, a second emitting part between the first emitting part and the anode and a third emitting part between the first and second emitting parts. The first emitting part includes a first EML, a p-doping layer between the cathode and the first EML, an n-doping layer between the first EML and the p-doping layer and a first ETL between the first EML and the n-doping layer. The second emitting part includes a second EML, and the third emitting part includes a third EML. The p-doping layer includes an HTL and first and second p-doping layers at both sides of the HTL, respectively.
