Description:

In this paper, we investigated the impact of OLED common layers on the performance OPDs and proposed two interfacial buffer layers, which simultaneously boost the EQE by 87-folds and suppress the dark current density by a factor of two. The introduced buffer layers are compatible with different EBLs and HBL/ETL materials, namely the buffer layers are universal. Besides, a prototype fingerprint recognition display sensor is demonstrated.
