开发了基于载流子和激子限制结构的具有降低的效率滚降的高效蓝色和白色OLED。记录的功率效率为46和44 lm W-1和25%的外量子效率在照明相关的亮度为1000 cd m（-2）的蓝色和白色OLED，分别实现，而不使用任何外耦合技术。
Highly efficient blue and white OLEDs with reduced efficiency roll-off based on a carrier- and exciton-confining structure are developed. Record power efficiencies of 46 and 44 lm W-1 and an external quantum efficiency of 25% at the illumination-relevant luminance of 1000 cd m(-2) are achieved for the blue and white OLEDs, respectively, without the use of any outcoupling techniques.
