CEATEC 2010: TDK Transparent OLED

TDK is showcasing 2-inch passive matrix transparent OLED displays at CEATEC 2010. The pixel format is limited to just 320×240. Light transmittance is claimed to be 50%. I can see potential for augmented reality sunglasses using transparent OLED display technology. I would think a potential military application is quite possible. Source: Tech On!
