Sharp's LCD and Scanner: An Integrated Sensing Display?

Cloaking Device

For those who haven't thought it through, this sort of technology is extremely revolutionary.

While it would be great on an iPhone — imagine it in clothing or on a tank. If each pixel can display what a sensing pixel on the other side of the person/tank sees, then... you have an invisibility cloak.

How does the tank know what direction you're looking at it from? You'd need each display and scan "pixel" to be prismatic so each point on the output side changes depending on your angle of view, and some sort of ray tracing to know how to pass the image through the solid body. And you still have the same lensing problem for the scan function. This would be nearly impossible to do with a discrete display.

The best you could hope for is a good color match and maybe a general sense of texture, which might improve camouflage but which could also be done more easily in other ways. You wouldn't get an image match.
