WHITE ORGANIC LIGHT-EMITTING DEVICE |
| 摘要 |
The present invention relates to white organic light-emitting devices having separate stacked blue/green phosphorescent and red phosphorescent layers. The white organic light-emitting devices emit the desired natural white color and show a reduced power consumption, superior current efficiency, efficacy, external quantum efficiency (EQE) and/or lifetime. In particular, the efficiency of the white organic light emitting device is improved and at the same time the lifetime of the white organic light emitting device is increased. |

1. A white organic light-emitting device comprising
(a) an anode, (i) a cathode, (e) an emitting layer between the anode and cathode, comprising
(e1) a first light-emitting layer and(e2) a second light-emitting layer, wherein the first light-emitting layer is in direct contact with the second light-emitting layer, the first light-emitting layer comprises a phosphorescent red emitter and a first host compound, and the second light-emitting layer comprises a phosphorescent blue emitter, a phosphorescent green emitter and a second host compound. |
