Canadian Researchers Create Thin-Film Flexible Paperphone 81

Posted by timothy from the staple-it-to-a-moose-for-long-distance-calls dept.
fergus07 writes "Researchers from the Human Media Lab at Canada's Queen's University have created a fully-functioning floppy E-Ink smartphone, which they also refer to as a paper computer. Like its thicker, rigid-bodied counterparts, the Paperphone can do things like making and receiving calls, storing e-books, and playing music. Unlike them, however, it conforms to the shape of its user's pocket or purse, and can even be operated through bending actions."

      In the very near term, maybe. To me, what makes this much more interesting is the ability to have a display that's just about any size you want. Fold it up and stick it in your pocket; when you just want to make a phone call, you leave it as-is, but if you want something larger, you just unfold it. I agree that the prototype's not much, but I can easily envision something the size of a large desktop display that you can fold up to phone size, 5-10 years down the road.

        Right, I really want paper creases down the middle of my screen... Actually this seems more like thin flexible plastic than paper. I think maybe the e-Ink display confused the journalists. It doesn't look like it would fold well though, just flex a great deal.

        For larger displays what we really need are wireless display standards. Like Bluetooth but for video. When I am watching TV and the phone rings in my pocket the caller ID is displayed in the corner of the TV screen. If I place the phone on my multi-touch table that becomes the screen and keyboard. If I want to present something my phone display appears on a digital whiteboard.

          I'm sure if they can figure out how to put a smart phone inside a thin sheet of plastic, they can figure out how to put some kind of hinge where it folds so that it actually folds and remains useful afterwards.

      In the long run, they will be more flexible. Add to that surface capacitance [wikipedia.org] or similar tech, then you can have more practical phones than the one shown, but that roll up or fit into spaces that curren't devices can't possibly fit into.

    • Less smartphone, more tablet. They have a serious disadvantage right now: Tablets will not fit in your pocket like a phone can. Make the screen flexible and they could furl or fold up. A long way to go though - the flexiscreen needs to be made bigger, higher resolution, color and touch-sensitive. Or it could just become a fold-up Kindle.

    There's a few things wrong with this prototype.

    1. No touch screen. Sure, "bend gestures" are an interesting idea, but that doesn't make up for the lack of touch screen. Touch screens are standard equipment on all of today's smartphones for a reason -- it's super easy to use. I'm not sure what would be involved in creating a flexible touch screen, but it could be a useful invention.

    2. No color. Sounds dumb, but a black and white web browser is not going to fly. I imagine this is going to be in the 2nd gen "e-ink" but that may be a while.

    3. The battery pack/logic part. The screen itself is great, but if there's a big "handle" attached to it that contains the battery, CPU, memory, etc. that's actually more cumbersome than just having a thick phone. My iPhone fits in my pocket, but this device would be tricky to squeeze in there. The size problem seems insurmountable due to the battery. Perhaps in a few decades we'll have incredibly small, flexible batteries, but that's a much, MUCH harder problem to solve.

      I think you're missing a point here. This isn't a polished end product, but a proof of concept. It doesn't have to have any of the features you describe as such - it only needs to demonstrate that it works.

      • Sure, I realize I'm missing the point, as it were. Educational institutions do research on crazy new technology, they don't develop products.

        But in terms of whether this could ever be used in a product, there's a lot of loose ends that they're glossing over (at least in what was posted here, I haven't read their research.)

    • The bending gestures are really awkward. Touching a screen is a lot more practical than bending it.

    • Yeah I think the article and the actual source material are both pretty fuzzy on whether they've implemented a whole phone in this technology or merely the display. I'd say the display is nice but there's a long way from a display to the whole gadget, and a lot of the mass of your typical smart phone is devoted to things (battery, power management, flash) that are going to be hard to implement in the same flat, flexible tech.

    As someone who does research in this area of technology, let me be the first to tell you that this is balls to the wall fucking awesome!! However, one issue they do not address is fatigue. As these displays are subjected to bending throughout their use, the nanoelectronics on the surface of the screen substrate are subjected to low strain cyclical stresses which fatigue the electrical components Eventually, fatigue failure occurs and the screen will die. This is a major issue in flexible electronics and is the only reason why there are not flexible displays in your pocket right now.

  • That's not a phone. It's an appliance. Like many so called phones these days, it's too damn huge and not really good on batteries. (Wouldn't a battery defeat its selling point)

    It is a flexible screen, not a phone.
    The screen is sticking out from a rather huge plastic housing, that includes the actual phone and battery.
    This may be a demo app for using flexing as an input method (which looks completly useless in the video), but calling it a flexible phone that "conforms to the shape of its user's pocket" is really stupid.

    "it feels like a thick piece of paper"

    Except for the Cellphone RF section and the Battery, those are still thick and not flexible so that you can have more than 30 minutes talk time and a range larger than 200 meters...

    Advances in battery tech and RF tech have not increased to the point where the claims of this "phone" can be a reality as a real product.

    Once the get a Li-Polymer battery that will not 1, Explode and 2, survive repeat flexing plus that pesky power capacity issue dealt with along with elimination of the need for any heat dissipation for the RF section along with significantly improved receiver sensitivity and transmitter efficiency... It's just a demo of vapor ware.

From what I recall their results have been promising for certain types of behaviour, and it certainly is great to have this level of basic investigation being done long before
