Sharp's Tiny LCD Doubles As Scanner

Posted by ryuzaki0 on from the where's-my-can-opener dept.

morpheus83 writes "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."

    This is the patent [uspto.gov] you're probably thinking of, filed on June 21, 2004.

    Abstract
    An integrated sensing display is disclosed. The sensing display includes display elements integrated with image sensing elements. As a result, the integrated sensing device can not only output images (e.g., as a display) but also input images (e.g., as a camera).
