46.4: Up-scaling of OLED manufacturing for lighting applications

First results of a newly developed Gen-2 manufacturing system for lighting and signage applications based on organic light-emitting diodes (OLED) are presented. High efficiency of 47.8 cd/A at C.I.E color coordinates of 0.39/0.38 at 1000 cd/m 2 was reached in forward emission applying a two-unit stacked white architecture. 100x100 mm 2-lighting-tiles showed a luminous efficacy of 18.5 lm/W (C.I.E color coordinates 0.45/0.43) based on integrating sphere measurements. Process reproducibility was analyzed in terms of run-to-run, day-to-day and tile-to-tile parameter variation.
