Sharp's Two-Way LCD

Some of the coolest stuff at CES isn't meant to be bought by you or me. Rather, it's technology we'll be seeing around us, sooner or later. Sharp Electronics, for example, showed off an intriguing two-way LCD--a screen that displayed one image when viewed from the right, and a completely different image when viewed from the left. It reminded me of those little Cracker Jack toys that showed different images as you tilted them from left to right.

To illustrate the technology for my camera, a Sharp representative held up a mirror to the display. You can see that the image reflected in the mirror is completely different from the one on the display:



Sharp says a display like this could be useful for digital signs, such as at the airport, where you could use it to show arrival information when viewed from one angle, and departures when viewed from the other.
