White light-emitting organic light emitting diode, method of preparing the same and deposition device for in-line deposition system

Abstract

A white light-emitting organic light emitting diode includes; a substrate, a first electrode disposed on the substrate, a second electrode disposed on the substrate and facing the first electrode, and an organic layer disposed between the first electrode and the second electrode, the organic layer including an emissive layer including a first emissive layer having a first light emitting material (“LEM”), a second emissive layer having a second LEM, a third emissive layer having a third LEM, a first mixed interface layer including at least a part of the first LEM and at least a part of the second LEM, and a second mixed interface layer including at least a part of the second LEM and at least a part of the third LEM, the first and the second mixed interface layers being interposed between the first and second emissive layers and the second and the third emissive layers, respectively. A white light-emitting organic light emitting diode including a substrate, a first electrode disposed on the substrate, a second electrode disposed on the substrate, the second electrode faces the first electrode and an organic layer disposed between the first electrode and the second electrode, the organic layer comprising an emissive layer including a first emissive layer including a first light emitting material, a second emissive layer including a second light emitting material and a third emissive layer including a third light emitting material, wherein the emissive layer comprises at least one layer of a first mixed interface layer including at least a part of the first light emitting material and at least a part of the second light emitting material, the first mixed interface layer being interposed between the first emissive layer and the second emissive layer, and a second mixed interface layer including at least a part of the second light emitting material and at least a part of the third light emitting material, the second mixed interface layer being interposed between the second emissive layer and the third emissive layer.
