We compared the characteristics of OLEDs with different ITO anode resistances for the device structures: ITO/TPD/Alq
3
/LiF/Al to investigate the effects of ITO anode resistance on OLEDs performance. The devices with lager ITO anode resistances exhibit lower current density and luminance at certain driving voltage
which may mainly be due to the presence of series resistance of the ITO anodes leading to a reduced effective driving voltage for charge injection.We found that the efficiencies of the devices are independent on ITO anode resistances.
