Sharp has begun showing off its two-way LCD screen, which shows different images depending on what angle you view it from. The company plans to use the technology in things like car navigation systems, allowing the driver to see a map in the center console while the passenger sees the Easy Rider DVD playing from the disc in the trunk. The main problem with two-way screens is that when you look at them straight on you see a combination of both images, meaning you have to view the screens at an angle for them to really work. However, the technology could be a real lifesaver for those road trips where the kids fight over what to watch in the back seat, although you'd presumably need two DVD players hooked up to service both the right-side people and the left-side people.
