NEC Lighting developed transparent OLED lighting panels that use a transparent ITO film - and they plan to commercialize these panels by 2015. The company unveiled a prototype 20x20 cm panel that features 70% transmittance, 35 lm/W efficacy and 20,000 hours lifetime (not sure if that's LT70 or LT50). This panel was developed in collaboration with Japan's New Energy and Industrial Technology Organization (NEDO).
Last week NEC Lighting announced that they developed the world's most efficient OLED device to day at 156 lm/W.Interview 2015:
