The European OLED100.eu project developed a new OLED lighting panel that is the largest to date: a 33x33cm² panel. The new panel offer 25lm/W at 1000 cd/m² luminance. This relatively good efficiency was achieved using ou-coupling and an efficient RGB OLED stack. The panels were fabricated at the Gen-2 line at the Fraunhofer IPMS.

The new panels are based on the on-substrate tiling concept - with 5 segments connected in series. The 33x33cm² panel itself is seamless and so can be tiled to create larger panels. The active area on each panel is 828cm² aperture ratio of 76%).
