OLED lighting prototypes shown in Tokyo's Lighting exhibition

Several companies are exhibiting new OLED lighting panels at the Lighting Fair 2009, in Tokyo.

Japan's Research Institute for Organic Electronics (RIOE) showed an OLED panel with 5,000cd/m2 luminance and only 15W power consumption (that's 15lm/W, like a incandescent bulb). They also showed a transparent OLED window (70% transparent).

Lumiotec, the Japanese joint-venture, had 1.9mm thick OLED panels on show. They actually plan to start making samples of those devices by fall 2009.

Panasonic actually displayed an even thinner panel - only 1mm. They think that OLED lighting will be ready within 2 years, but it will take much longer (10 years) for it to be used main lighting.

Philips exhibited their Lumiblade OLED panels. They recently built a new plant in Aachen, Germany, to make those panels.
