We’ve seen transparent displays in plenty of experience concept videos and product designs over the years. But now, products and technologies on display at this year’s CES suggest that truly transparent displays will be a commercial reality within the next couple years.

Samsung continues to show off their extremely impressive “Smart Window”: Story at SlashGear
The Vuzix and Lumus technologies work by projecting a video feed in to the edge of a piece of glass.

I’m not sure how the Samsung Smart Window works, but it appears to be an adaptation of traditional LCD display technology, without a reflective or backlight backing.
