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."

      It is not! You forgot:

      Sharp's optical scanning LCD screen will be ready for commercial use by the first half of 2008.
      There, now it is the full article.

  3. Old support joke anyone? by Ailure · · Score: 4, Funny

    This so reminds me about the old support joke about a user trying to send a document, by holding it up in front of the screen. :)

  4. Planar Patent by feyhunde · · Score: 4, Interesting
    Actually Apple doesn't have the patent. Planar Systems owns it. They've built up to 19 inch versions to my knowledge. But this tech is flawed as P-Si works best at receiving light in wavelengths either dangerous to human health in a display, or get absorbed by the polarizers.

    Here's a link to a 2003 white paper for the Society of Information Displays that explains the tech completely and much more than the article http://www.planar.com/advantages/whitepapers/docs/Planar-AMLCD-Optical-Touchscreen.pdf

    From the article And since each pixel has a scanner it may as well be a multi-touch screen. Am I the only one who remembers TV screens that provide the surveillance video back to the big brother?
