In a report from PC World, Sharp has improved upon the conventional touchscreen model with a prototype that uses optical scanner pixels interspersed with the LCD pixels, instead of a wire grid. The 3.5-inch screen can scan fingerprints, utilize multi-touch functionality (even more than the iPhone’s two fingers), and even scan name and business cards in under a second at up to 320 by 480 pixel resolution. Supposedly, similar technology was introduced in 2003 by Toshiba Matsushita Display Technologies, but the technology never took off after its April exposition at the Electronic Display Expo in Tokyo. Potential uses for Sharp’s tech include cellphone screens, gaming devices, and possibly PDAs.
