Transparent Screens on the Horizon?
mhesseltine writes "According to United Press, researchers in Japan are developing transparent transistors. This could bring about see-through screens like those in Minority Report. Also, I imagine would be better heads-up displays (HUDs) for vehicles, layered flat panel displays, and new methods of interfacing with information screens."
I actually think it'd be hard to see a full colour image behind a HUD type display. The colours in the background would blend with the colours in the HUD display. That's why HUDs always use monocrome green.
