摘要
OLEDs containing a stacked hybrid architecture including a phosphorescent organic emissive unit and two fluorescent organic emissive units are disclosed. The stacked hybrid architecture includes a plurality of electrodes and a hybrid emissive stacked disposed between at least two of the electrodes. The stack contains at least three emissive units and at least two charge generation layers. At least one of the three emissive units is a phosphorescent organic emissive unit and at least two of the three emissive units are fluorescent organic emissive units. More specifically, the two fluorescent organic emissive units may be blue organic emissive units that emit light from the same or different color regions.
