A new interlayer is successfully used to be a universal carrier switch,developing high-performance hybrid white organic light-emitting diodes(WOLEDs).By dint of this interlayer,the two-color hybrid WOLED shows a maximum total current efficiency(CE) and power efficiency(PE) of 48.1 cd/A and 37.61m/W,respectively,while the three-color hybrid WOLED shows a maximum total CE and PE of 33.8 cd/A and 25.71m/W,respectively.The color rendering index of the three-color hybrid WOLEDs are > 75,which is already a sufficient level for many commercial lighting applications.In addition,both the two-color and three-color hybrid WOLEDs show low efficiency roll-off and stable color.Furthermore,devices with the new interlayer show much higher performance than devices with the most commonly used 4,4-N,N-dicarbazolebiphenyl and N,N’-di(naphthalene-l-yl)-N,N’-diphenyl-benzidine interlayers.
