I can't tell if it's a feature of the screen or just the very dark nature of subway tunnels, but I really like the fact that the screen goes completely opaque on the bright blue screens.
Transparent screens could be useful in all sorts of scenarios, but I think tech demos too often ignore the fact that, most of the time, you want the image to be as clear as possible, which means opaque.
I wonder why no one suggested putting a very thin, transparent monochrome LCD behind one of these. It would allow darkening the background, as opposed to OLED's ability to emit light but not block it from passing through. Basically, you'd use two display technologies to complement each other.
I'd love to see transparent screens in windows, like, real holes in buildings and furniture that are usually filled with glass. This would be a step towards ambient computing.
