A single-unit OLED is shown to have a current efficacy of 46.8 cd/A at a luminance of 1215 cd/m(2). When two of these OLEDs are stacked, the double-unit OLED exhibits a current efficacy more than twice that of the single-unit OLED, with a current efficacy of 97.8 cd/A at a luminance of 1119 cd/m(2). With the addition of an optical outcoupling layer of N,N'-Di-[(1-naphthyl)-N,N'-diphenyl]-1,1'-biphenyl)-4,4'-diamine (alpha-NPD) on top of the semitransparent gold anode, the double-unit stacked OLED achieves a maximum current efficacy of 205 cd/A at a luminance of 103 cd/m(2), maintaining a high current efficacy of 200 cd/A at a luminance of 1011 cd/m(2). These stacked inverted OLED combine the advantages of inverted OLEDs with the benefits of having a stacked architecture.
