Samsung's New Carbon Nanotube Color E-Paper

Iddo Genuth writes to tell us that Samsung and Unidym have shown the world's first carbon nanotube-based color e-paper. Interestingly, the new film is electrically conductive while remaining almost completely translucent and only 50 nanometers thick. "The company also mentions that the EPD [electrophoretic displays] has important advantages over conventional flat panel displays. EPDs have very low power consumption and bright light readability, which means that even under bright lights or sunlight, the user would be able to view the display clearly. Furthermore, since the device uses the thin CNT films, applications can include e-paper and displays with thin, flexible substrates. Power consumption is lowered due to the EPD's ability to reflect light and therefore able to preserve text or images on the display without frequently refreshing."

    Some years ago I believed that the pocket computer would be fairly similar to today's smartphone, although I admit the gesture-based, touch-sensitive I/O eluded my imagination. So I think it's time to revisit the computer of the future and determine what exactly should constitute the next generation of the smartphone/pocket computer. To that end I present my ultimate wish-list computer. This, of course, is in addition to the built-in features of current smartphones.

    Let's reiterate what we already have built into these devices. There is the phone itself plus various software subsystems. Many have GPS and mapping built in, often with turn-by-turn software for travel routing. And many can work as adding machines, word processors, PowerPoint presenters, and databases. Some can scan bar codes. Most are MP3 players as well as photo albums.

    The small form factor that we have today is pretty much what I'd expect will remain. So what are some other possibilities?

    Smart screens and keyboards. When I first thought of the pocket computer as an all-purpose machine, I imagined it would fit into a cradle/docking station so that users could hook up a real keyboard and monitor. But there's no reason this cannot be done wirelessly. Imagine walking into your office and plopping down your little computer/phone. It automatically connects to a "smart monitor" and "smart keyboard" and drives both.

    Voice command and speech recognition. This, of course, is the holy grail of pocket computing. You won't find yourself complaining about virtual keyboards if speech I/O ever works well.

    Clear voice technology. While on the subject of voice, it would be even better if the device could talk back to you in a clear, understandable, and pleasant voice.

    Situational awareness. The smartphone should know when to turn itself off by knowing where it is. The idea is that when your phone is in an airplane, for instance, it turns itself off. It goes to vibrate mode automatically in other situations, such as in the theater. There are a lot of different methodologies for making this work.

    Ownership awareness. The device simply will not work for anyone other than the owner.

    Induction charging. The battery should charge using various induction tricks. An entire desk could be an induction mechanism for example, so when the phone is lying on the desk it is charging.

    Broadcast TV reception. I have never been sure why there are so many weird TV technologies for portable devices when the broadcasting grid could be used just as easily. Let the device act as a portable TV receiver.

    Built-in projector. There's no reason the perfect phone cannot have a built-in micro-projector.

    Point-to-point walkie-talkie. This could come in handy in an emergency if nearby cell towers are down.

    Extensible. There is no reason why various mechanisms cannot be put into the device to turn it into any number of laboratory instruments and useful gizmos. It could serve as a pH meter, a blood sugar checker, a blood pressure tester, and a postage meter scale. It could also be the basis for a car tune-up aid and all sorts of other things.

    There you have it. And I bid you good luck if you own Apple.

      Paired Bluetooth devices, perhaps. You wouldn't be able to just plonk down next to any old set of monitor and keyboard, of course, you'd need to authenticate them at least once, otherwise anybody carrying around such devices could trivially compromise your system. But if you're going to be tied to a specific set of keyboards and mice and monitors which your computer will allow to connect to it, you might as well use a docking station and save the battery.

      I don't want to talk to my portable computer. That's utterly obnoxious: people talking loudly on their mobiles on the bus are bad enough, people chattering away to a robot in their pocket would be a nightmare. I'd quite like voice control of a home automation computer, though.

      Situational awareness. The smartphone should know when to turn itself off by knowing where it is. The idea is that when your phone is in an airplane, for instance, it turns itself off. It goes to vibrate mode automatically in other situations, such as in the theater. There are a lot of different methodologies for making this work.

      For it to know it's in such a place, there'd have to be a standard signal that says 'This is a place you should be switched off'. Trivial denial of service attack. I suppose you might be able to do something with GPS - detect a plane by the speed, detect cinemas by a database of known locations - but who maintains the database? Google, maybe?

      Ownership awareness. The device simply will not work for anyone other than the owner.

      Solve that problem and you'll be the richest man in the industry. How does the owner authenticate reliably? Whole-disk encryption with a strong passphrase, maybe. But you just know most people will set it to 'password', or the name of their cat.

      Broadcast TV reception. I have never been sure why there are so many weird TV technologies for portable devices when the broadcasting grid could be used just as easily. Let the device act as a portable TV receiver.

      On TV frequencies you'd need a big antenna. Wavelength is something like 50cm. There's a reason we use microwaves for Wi-Fi and mobile phones.

It could serve as a pH meter, a blood sugar checker, a blood pressure tester, and a postage meter scale. It could also be the basis for a car tune-up aid and all sorts of other things.

    the world's first carbon nanotube-based color e-paper.

    How much extra do I have to pay for the additional unnecessary buzzword? I don't recall carbon nanotubes being particularly cheap.

    even under bright lights or sunlight, the user would be able to view the display clearly

    B&W LCDs are so terribly under-appreciated... I still keep my decades old PDAs working specifically because B&W LCD screens are superior, but rather difficult to find (in reasonably large sizes) now.

    Hell, I'd love to get a 15" B&W LCD screen for my PC... Infinitely easier to read text on without eye strain, and vastly lower power than any other technology out there. You can always do the dual-desktop thing, and only turn on your second (color) LCD screen when you need to look at something in color like pictures, maps, etc.

    One for my laptop wouldn't be a bad idea either... Get rid of the backlight and you'll likely more than double your existing battery run time.

    EPD's ability to reflect light and therefore able to preserve text or images on the display without frequently refreshing.

    Refreshing an LCD screen has nothing to do with the backlight... Only with CRT & Plasma displays are the two issues linked.

    And this conveniently ignores the fact that e-ink screens have TERRIBLE power consumption when the screen contents ARE changed frequently.

  25. Why the feeble jokes? by Kupfernigk · · Score: 2, Interesting
    This is actually a real technical breakthrough. The point is that the nanotubes are highly conductive and highly transparent so the display can be made much larger (and thinner)than hitherto. LCDs have quite a thick electrode layer on the front to provide enough conductivity and this is one of the limiting factors. The holy grail of e-paper, the thing to drive widespread usage, is the ability to deliver a full A4 or USL size page, at which point it has a big future in business. For anybody who hasn't noticed, business discussions (as distinct from people sitting around chewing fat on zero-information-content PP slides) usually require participants to wade through long reports, which still need to be printed, and which are then discarded (and have to be shredded...).

    A workable e-reader would have a market here which is initially niche but would then provide the revenue to get to the fully commercialised A4 e-reader - which makes electronic delivery of newspapers and magazines fully practical. The decline in value of internet content is driven by the advertiser-funded model. Paid-for services offering real value would love a locked down e-reader. (and I personally don't mind paying for worthwhile services. By buying a subscription to e.g. Scientific American, I help guarantee its editorial independence and ability to fund articles that would lose certain advertisers.)

    Proof of concept of a workable full page e-reader, during a recession when people are looking for disruptive technologies that may offer a good return? This could easily be the most important thing on Slashdot this week.

      I'd be happy if they'd just make some sort of decent digital paper affordable enough that normal geeks could make stuff with it.

      e.g. I've wanted to mod an iMac so that the entire case is done in digital paper so that it acts as a screen without nasty backlighting. Could make an interesting look, be fun, and allow nice display of stats.

      I'm sure I could come up with endless ideas if the stuff wasn't so damn expensive. I keep hearing that they'll be doing cereal boxes and greeting cards in this stuff but I can't see it happening for a long time if the current prices mean anything.

      Translucent means "allows photons through, but not in a straight line". This means, all the light travelling through becomes diffused and blurred. Every photon may get through, but just not in the direction it started from. Just like those clear plastic folders used to protect sheets of paper in ring binders. Pressed against the paper, you can see the paper clearly. Lift the plastic cover up, and you can't see the text on the paper.
