Sharp’s tiny LCD doubles up as a scanner
It’s all of 3.5-inches but this LCD screen from Sharp features an integrated optical scanner that could be used to scan business cards, but also be used as a method for multi-touch input. The prototype was seen at the Ceatec exhibition. Possible uses include the ability to recognize fingers or other objects and as biometric lock on your phone. And since each pixel has a scanner it may as well be a multi-touch screen.
Sharp’s optical scanning LCD screen will be ready for commercial use by the first half of 2008.
