UPDATE: We have some new photos from Engadget (who's got a video, too).
Rohm is showing a new wristband with an OLED display. Their idea is that OLEDs can actually be used in jewelry or a watch band. OLEDs are expensive, but so are jewelry pieces so they think that it might be a good usage for the technology. The OLED in the wristband is 0.3mm thick, and run via a small lithium-ion battery.
Rohm is also showing OLED table lights (one inch wide, 4 inches tall). One of their OLED lamp prototypes consumes about 300 milliwatts.
