摘要： An organic light emitting display device includes a substrate including first to third pixel regions; and an organic light emitting diode including a transparent electrode, a reflective electrode and a light emitting layer between the transparent electrode and the reflective electrode. The light emitting layer in the organic light emitting diode in the first pixel region includes a first emitting part including a first emitting material layer and a second emitting part including a second emitting material layer. The light emitting layer in the organic light emitting diode in the second pixel region includes a third emitting part including a third emitting material layer and fourth emitting part including a fourth emitting material layer. Each of the first and fourth emitting material layers is a fluorescent emitting layer, and each of the second and third emitting material layers is a phosphorescent emitting layer.

摘要： An organic light emitting diode can include a reflective electrode, a transparent electrode facing the reflective electrode, and an organic light emitting layer including a first emitting part and a second emitting part and positioned between the reflective electrode and the transparent electrode. Each of the first and second emitting parts includes a phosphorescent emitting layer and a fluorescent emitting layer. In at least one of the first and second emitting parts, the fluorescent emitting layer is positioned to be closer to the transparent electrode than the phosphorescent emitting layer. An organic light emitting device can include the organic light emitting diode and can be a display device or a lighting device.

摘要： The present disclosure relates to an organic compound including an electron acceptor moiety of a hetero aromatic ring having at least one nitrogen as a nuclear atom and an electron donor moiety of a fused aromatic or a fused hetero aromatic ring linked to the electron acceptor moiety directly or via a linker moiety, and an organic light emitting diode (OLED) and an organic light emitting device including the organic compound. The organic compound includes both the electron acceptor and donor moieties, thus charges can be transported easily within the molecule. The OLED and the organic light emitting device including the organic compound, which may comprise at least one substituent having strong electron withdrawing property at specific position, in an emissive layer can implement excellent luminous efficiency and luminous lifespan.

摘要： An inorganic light emitting diode in which at least one energy control layer including an organometallic compound interacting with a hydroxyquinoline moiety is disposed between an emitting material layer and at least one charge transfer layer and an inorganic light emitting device including the diode are disclosed. An exciton recombination zone is formed at the central region in the EML, and inorganic luminescent particles have minimal surface defects by introducing the energy control layer. The inorganic light emitting diode and the inorganic light emitting device can improve their color purity and luminous efficiency.
