Sharp announces new optical-sensing touchscreen display – better than iPhone multi-touch screen

“Sharp has announced a new touchscreen LCD  that not only rivals the iPhone’s multi-touch display (manufactured by Balda), but blows it out of the water.

For example, users can easily tap the screen with two fingers to enlarge or reduce a displayed map.
