Abstract
An organic light emitting diode, which includes a substrate, a first electrode, at least one of red and green emissive layers, a blue emissive layer, a second electrode, and an exciplex elimination layer that is formed between at least one of the red and green emissive layers and the blue emissive layer; the exciplex elimination layer acts to confine carriers in at least one of the red and green emissive layers.
Claims14
An organic light emitting diode, comprising a substrate, a first electrode, at least one of a red emissive layer and a green emissive layer, a blue emissive layer, a second electrode, and an exciplex elimination layer formed between the at least one of the red emissive layer and the green emissive layer and the blue emissive layer;
- wherein the exciplex elimination layer is configured to confine carriers in the at least one of the red emissive layer and the green emissive layer,
- a host material of the blue emissive layer comprises 2-methyl-9,10-bis(naphthalen-2-yl)anthracene, and a guest material of the blue emissive layer comprises 1-4-di-[4-(N,N-diphenyl)amino]styryl-benzene, a doping concentration of the guest material is about 5%, and
- the first electrode is an anode, the second electrode is a cathode, the at least one of a red emissive layer and a green emissive layer is closer to the anode than the blue emissive layer and the blue emission layer is closer to the cathode than the at least one of a red emissive layer and a green emissive layer.
A manufacturing method of an organic light emitting diode, comprising:
- forming a first electrode, and at least one of a red emissive layer and a green emissive layer on a substrate;
- forming an exciplex elimination layer on the at least one of the red emissive layer and the green emissive layer;
- and
- forming a blue emissive layer and a second electrode on the exciplex elimination layer,
- wherein the exciplex elimination layer is configured to confine carriers in the at least one of the red emissive layer and the green emissive layer,
- a host material of the blue emissive layer comprises 2-methyl-9,10-bis(naphthalen-2-yl)anthracene, and a guest material of the blue emissive layer comprises 1-4-di-[4-(N,N-diphenyl)amino]styryl-benzene, a doping concentration of the guest material is about 5%, and
- the first electrode is an anode, the second electrode is a cathode, the at least one of a red emissive layer and a green emissive layer is closer to the anode than the blue emissive layer, and the blue emission layer is closer to the cathode than the at least one of a red emissive layer and a green emissive layer.
