Two different emitting compound, 1-[1,1';3',1"]Terpenyl-5'-yl-6-(10-[1,1';3',1"]terphenyl-5'-yl-anthracene-9-yl)-pyrene(TP-AP-TP)and Poly-phenylene vinylene derivative(PDY 132)were used to white OLED device. By incorporating adjacent blue and yellow emitting layers ina multi-layered structure, highly efficient white emission has been attained. The device was fabricated with a hybrid configuration structure : ITO/PEDOT(40nm)/PDY-132(8~50nm)/NPB(10nm)/TP-AP-TP(30nm)/Alq3(20nm)/LiF(1nm)/Al(200nm). After fixing TP-AP-TP thickness of 30nm by evaporation, PDY-132 thickness varied with 8, 15, 35, and 50nm by spin coating in device. The luminance efficiency of the white devices at 10mA/cm2 were 2.93 cd/A~6.55 cd/A. One of white devices showed 6.55cd/A and white color of (0.290, 0.331). |
