LCD Screen With Embedded Optical Sensors

Posted by ScuttleMonkey on from the the-screen-that-looks-back dept.

dk3nn3dy writes "Sharp has developed a LCD display with optical sensors built into the displays pixels, without requiring a touch-sensitive film to be bonded on top of the regular screen. The optical sensor is similar to that used in scanners, allowing for notes or business cards to be scanned by the screen itself. As the optical recognition technology is built into the pixels it also simplifies tactile recognition based on simultaneously touching multiple points. Future uses include fingerprint authentication on the screen of your mobile phone or PDA, or iPhone style touch recognition. Volume production will start next spring."

    I heard development was funded almost entirely by Windex.

    How do I see the screen to click the 'Scan' button when I've got the document in front of it?

    sorry. =)

    Right, just like your keyboard allows you to share your most personal and private info to the world. But you just won't, how about that.

    Also: it works as a scanner, not a camera. It sees in focus only what's directly placed on top of the screen.

    Good for barcode scanning, touchscreens, or portable scanner. As well as a bunch of other quite cool and "non-evil" uses.

    This reminds me of that old 1995 email joke about having a scanner in your screen, and you could hold your face up to it and it would take your picture. Of course, all it did was load a picture of a monkey and said this was you.

    All you need is the right software to access it. Fortunately, there are several websites out there that allow you to do this - e.g. amazingcamera.com

    It definitely seems like a similar concept.

  7. All OLED screens can do this already by maokh · · Score: 5, Informative

    All LEDs inversely function as light detectors, even while emitting light. All that is really needed is a display controller that is designed to detect this reverse current flow. It would be interesting to see such an application. The only thing I have seen so far is a traditional LED matrix that works like a touch screen to turn each individual LED on and off.

    Don't believe me? Here is a primer:
