    Sharp recently made some headlines with the demonstration of a prototype LCD that doubled as a scanner.

    The 3.5" LCD screen integrated an optical scanner that could be used to scan business cards, but also be used as a method for multi-touch input.
    The prototype is expected to see commercialization in the first half of 2008.

    While not directly linked to Apple, the technology is very similar to an old patent application from Apple which described an "Integrated Sensing Display". Apple's patent described possible uses in video conferencing and photos, but could have also been used for a multi-touch display. Of course, Apple has since come out with the iPhone which offers a multi-touch display. The iPhone, however, uses a capacitance-based touch screen, rather than one based on image capture.

    Apple continues to research and develop various touch-based technologies. Their most recent patent applications include pressure sensitive input technology on existing touch screens.

    Now that could be an interesting addition to iPhone v2!

    but I feel its a bigger wow factor than practability factor!

    I would like to see it in action though

    Kinda spooky to think that we might some day wind up with screens that double as cameras. :eek:

    back to plastic?

    As to the pressure sensitive part ...
    doesn't this mean that we have to go back to plastic (deformable) screens?

    This process certainly won't work with a milimetre or two of glass in front of the display, and Apple has just finished re-tooling their entire line to use glass screens. This kind of implies that this is for a product in the future, not "iPhone 2.0."

    This has the 'potential' to be cool. However in reality it will probably be fiddly, and require you to do retakes and be precise, as current touch screen devices to. But still, it's nice to know that we're getting there eventually.

    I wonder if this would lead to your boss watching you while you worked at your computer. Hell, NOBODY'd look at anything remotely adult while they worked. ;)

    Sounds pretty cool. Maybe someone can adapt it so we can have the viewscreen kind of thing in Star Trek.

    The reason the iPhone has glass in front is to keep it scratch-free (as opposed to a plastic only screen).

    Makes a lot of sense. The color filters used for the LCD, with a photodiode behind them, could make for a very simple scanner. The awkward part would be preventing the backlight from flooding the sensor, and only capturing the reflected light from the object. I don't think this will work as a camera-- your face, for example, would be reflecting light to all the sensors at once creating one big blur. It would require really sophisticated and expensive lensing to be able to keep this flat and viewable while being able to capture an image of an object at any distance.

    Such a device would likely be a plus for businessfolk. Be nice to just drop someone's business card on your iPhone display and it scans into your Contacts.

    hmmm... i wonder how much battery this would suck up? and how much memory could be packed on? this would be cool on the ipod touch/iphone v2, but i don't see it coming out for another couple of years (well, at least 1.5)

    As i said at the time that patent first appeared this has the potential to be very useful indeed. Say this was built into tablet PC, now in a lecture/other situation you get a document that you want to annotate just put it on the display and then there it is on the screen. amazing.

    I thought of this idea too when I saw the Microsoft multi-touch coffee table. Just put a picture or something on the screen face down and it scans it into the computer :) Cool ideas!

    I have heard things about Apple making a display with sensors behind it so you can do iChat video conferencing without an iSight because it it built in behind the screen. Anyone know anything about that???

    Sharp is probably way ahead of Apple and most others in this field.

    Well Sharp has a working model, but Apple's patents precede it by years, and their technology (assuming it ever works well enough) can do far more than just low-res scan a business card.

    So Sharp might be ahead on implementation, but assuming Apple's patent is not just hot air, Apple's technology is actually "way ahead" of Sharp's.

    Note that Apple doesn't actually have a patent on this, it's just the publication of their patent application. Now, that said, if Sharp hasn't applied for a patent on this technology (which i sincerely doubt), even if Apple does not obtain a patent for it the patent application publication can be used against Sharp's application (assuming the claims are close enough in scope).

    It would be interesting to see Sharp's related patent applications and their dates of filing and subsequent publication relating to this technology.

    That could make for the coolest laptop! Shut your book to scan, flip it open and edit your image! Must be James Bonds favourite gizmo in 2013.

    : )

    fingerprint scanning for security, could be an application.

    It won't be used in wide variety of products. It make 2-4-6 or even more years to be ready for massive market.

    I have had this idea since I saw the Apple patent built into the display for things like iChat. I imagine a 15 inch convertible tablet with 1920x1200 screen with a full screen built-in camera for HD video plus multi-touch. Scanning would even be better than this prototype because you could close the tablet like a laptop and block out outside light to get a better scan. I am predicting one of these for January:D

    This puts a whole new spin on the old joke about holding the piece of paper up in front of the screen and hitting "print". Talk about coming full circle.

    It is interesting to note that in 1984, Big Brother kept an eye on citizens by looking at them through their TVs.
