  • Publication number: 20240276762
    Abstract: An organic light emitting diode (OLED) and an organic light emitting device (e.g., a display device or a lighting device) thereof are described. The OLED comprises a first electrode, a second electrode, a first emitting part (including a first hole transporting layer (HTL) and a first emitting material layer (EML), positioned between the first and second electrodes); and a second emitting part (including a second EML and positioned between the first emitting part and the second electrode). The first EML is a blue EML, and the second EML includes at least one of a red EML and a blue EML. The first hole HTL includes a high refractive layer having a first refractive index, and a low refractive layer having a second refractive index, positioned between the high refractive layer and the first EML, where the second refractive index is smaller than the first refractive index.

  • Publication number: 20240276747
    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. The OLED can include a first blue emitting material layer including a first host, and a second blue emitting material layer including a second host, disposed between two electrodes. The OLED includes two blue emitting material layers so that an exciton recombination zone is distributed within the blue emitting material layers irrespective of current density or gradation. As the amount of non-emitting excitons accumulated outside of the emitting material layers is minimized, the driving voltage of the OLED can be lowered, and the luminous efficiency and the luminous lifespan of the OLED can be improved.

  • Publication number: 20240260293
    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. The OLED can include a blue emitting material layer including plural hosts with adjusted energy levels. A HOMO energy barrier between the at least one blue emitting material layer and at least one hole transport layer and/or electron blocking layer can be minimized. Holes generated at an anode or a P-type charge generation layer can be injected rapidly into the at least one blue emitting material layer without accumulating at an interface between the hole transport layer and/or the electron blocking layer, and the at least one blue emitting material layer. As the amount of non-emitting holes is minimized, the driving voltage of the OLED can be lowered, and the luminous efficiency and the luminous lifespan of the OLED can be improved.
