Here's another nice OLED lighting installation from the Milano art show, this time from Panasonic Electric Works (PEW). Apparently PEW's OLED panels are transparent when not lit.

Just a couple of weeks ago we learned that PEW and Idemitsu Kosan will establish a new joint venture (called Panasonic Idemitsu OLED Lighting) for developing, manufacturing and marketing OLED lighting panels. The new company will combine PEW's design and manufacturing technologies with Idemitsu OLED materials.
