When transparent LCD technology started popping up as consumer tech prototypes a few years ago, it was quickly dismissed as gimmick, or something for a marketing kiosk. But looking at this touchscreen concept from Fujitsu—which is double-sided and transparent—makes you wonder if there isn't hope for this tech yet.

As the video shows, the implications for gaming are especially intriguing, since you could still control the action with your grubby little fingers, but not have to obscure your view in the process. It basically takes the idea of the PS Vita's rear touch panels one step further.

But of course, there's the issue of visibility and color depth, which, by the screen's very nature, makes it inferior to a standard LCD. Maybe someday, we can have the best of both worlds. [DigInfo via Engadget]
