Highly efficient blue top emission organic light emitting diodes with remarkable blue index (BI) of 305 was shown in this paper. The remarkable BI was achieved through a combination of high-mobility electron/hole injecting/transporting layers, customized high reflectivity Ag anode, CPL with high refractivity and carefully engineered device configurations.
