Organic light-emitting diode double layer device

Date:Sep 17, 2019

On the basis of single-layer devices, two-layer devices add hole transport layer (HTL) or electron transport layer (ETL) on both sides of the luminescent layer to overcome the imbalance of carrier injection in single-layer devices, improve the voltage-current characteristics of the devices, and improve the luminous efficiency of the devices.
