Here's a nice video showing Verbatim's tunable OLED lighting panels (Velve), taken at the L+B 2012 exhibition:
These panels are Verbatim's 2nd-Generation panels, which are twice as bright than the original panels at 2,000 cd/m². The company offers two panel sizes: 131x44 mm and 65x72 mm. Verbatim can also create custom-made OLED panel sizes, and indeed in the video you can spot three different sizes. The Velve OLED lighting panels are made together by Mitsubishi and Pioneer, and are the world's only color-tunable OLED lighting panels.
