Abstract

Abstract : Efficiency and operation lifetime of blue triplet‐triplet annihilation organic light emitting diodes (TTA‐OLEDs) were enhanced by 16% and 297%, respectively, by employing double emitting layer structure. Blue OLED with maximum external quantum efficiency of 9.4% and half‐lifetime of 96, 620 hours at initial luminance of 1, 000 cd/m 2 was achieved.
