The development kits (pictured above) include one 145mm x 145mm OLED panel, a controller and an AC adapter. They cost ¥84,000 each (about $930) a little higher than what they said a couple of weeks ago.
The panel is 4.1mm thick (the thickest part is 4.8mm). The light emitting area is 125mm x 125mm. It weights 195g, the average color rendering index is Ra80, and the maximum brightness is 4,000 cd / m2. The lifetime is quoted at 30,000 hours (at 1,000 cd / m2 brightness level)
