Abstract: The present invention provides an emissive region in organic light emitting devices having a combined emission from at least two emissive materials, a fluorescent blue emissive material and a phosphorescent emissive material. The emissive region may further comprise additional fluorescent or phosphorescent emissive materials. Preferably, the emissive region has three different emissive materials—a red emissive material, a green emissive material and a blue emissive material. Organic light emitting devices incorporating the emissive region provides a high color-stability of the light emission over a wide range of currents or luminances.

Abstract translation: 本发明提供了具有来自至少两种发射材料，荧光蓝色发射材料和磷光发光材料的组合发射的有机发光器件中的发射区域。 发射区域还可以包含另外的荧光或磷光发射材料。 优选地，发射区域具有三种不同的发射材料 - 红色发射材料，绿色发射材料和蓝色发射材料。 结合了发射区域的有机发光器件在宽范围的电流或亮度上提供了高发光的颜色稳定性。
