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.

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.

Abstract: An organic light emitting diode (OLED) and an organic light emitting device comprising the OLED are described. The OLED can comprise a first electrode; a second electrode facing the first electrode; and a first emitting part (including a first blue emitting layer and a second blue emitting layer), which is positioned between the first and second electrode. The second blue emitting layer is positioned between the first blue emitting layer and the second electrode and contacting the first blue emitting layer. The first blue emitting layer includes a first host and a first dopant, and the second blue emitting layer includes a second host and a second dopant, wherein the first host is a pyrene derivative, and the second host is an anthracene derivative. An organic light emitting device can include the OLED, and can be a display device or a lighting device.

Abstract: An organic light emitting diode (OLED) is described, having an emissive layer with an emitting part including at least one emitting material layer, a first electron transport layer, and a second electron transport layer disposed sequentially between two facing electrodes. The first electron transport layer includes a first electron transporting material of an azine-containing compound and the second electron transport layer includes a second electron transporting material of a benzimidazole-containing compound. The first electron transport layer, with controlled electron transporting property and energy level, is disposed adjacently to the at least one emitting material layer and the second electron transporting layer is disposed adjacently to the second electrode or an electron injection layer so that the OLED can lower driving voltage and can maximize luminous efficiency and luminous lifespan. An organic light emitting device including the OLED can be a display device or a lighting device.
