Abstract

Yellow organic light emitting diode (OLED) with Red/Green emitting layer (EML) sequence showed higher efficiency than device with Green/Red EML sequence because of the electrical carrier conduction difference in EMLs. Based on this result white OLED with additional blue emitter was demonstrated with maximum efficiency of 18.3 cd/A at 100 cd/m2 and good color stability.
