LG Display showcases 11.5-inch flexible e-paper

by Darren Murph, posted Jun 4th 2009 at 11:52PM

We're still years away from commercialized color variants, but LG Display is proving that bigger ain't really a thang. In fact, it recently showcased an 11.5-inch sheet of flexible e-paper at SID 2009, which could obviously be used in the Kindle XXL. Sadly, few (and by few, we mean none) details were given regarding an eventual launch date, but hey, at least it's around, right?

Foam-infused Impress DIS.PLAY encourages touching

by Darren Murph, posted Feb 24th 2009 at 7:03AM

Move over Surface, we just found our next tabletop display. The aptly named DIS.PLAY beautifully merges the functionality of a touch panel with the allure of dimly-lit scenarios, and the inclusion of memory foam just makes it all the more sweet. In one usage scenario, we're told that objects could be put into motion with sound, and when a certain "shape" is mashed and deformed, the respective audio would bend along with it. Another instance showcased 3D modeling that could be varied by simply twisting the hand or intensifying a finger press. Check the demonstration video after the break, and grab your Tempur-Pedic pillow if you're looking to play along.

South Korean scientists get one step closer to graphene-based gadgets

by Darren Murph, posted Jan 16th 2009 at 10:07PM

Graphene-based gadgets are coming, we just know it. Trouble is, we're still a long, long ways away. That said, a team of South Korean scientists are bringing us ever closer to bendable, durable gizmos by creating a graphene film with a diameter of 10 centimeters by "adopting a conventional chemical vapor deposition (CVD) technique." Furthermore, the crew's development of what's being called the "world's first circuit patterning technology for the graphene film has the potential to replace silicon-based semiconductors." If this is just way too heavy for your mind to digest on a Friday, here's the skinny: the newfangled manufacturing process has, for all intents and purposes, overcome the limitations of graphene, which could not be made large enough for commercial applications in the past.

HP and ASU demo bendable, unbreakable electronic displays

by Darren Murph, posted Dec 8th 2008 at 10:30AM

Well, what do you know? Nearly four years after Arizona State University opened its very own flexible display center comes this, a prototype device that's purportedly easy to manufactur, easy on the environment and practically as strong as Thor. HP and ASU have teamed up to demonstrate the fresh e-displays, which are constructed almost entirely of plastic and consume far less power than traditional computer monitors. The "unbreakable displays" were crafted using self-aligned imprint lithography (SAIL) technology invented in HP Labs, and while we'd love to see this in a pliable laptop at CES 2009, we suspect it'll be a few years yet before these slither out to the commercial realm.

Update: HP Labs pinged us with this tidbit on the image above. "This image from the Flexible Display Center at ASU represents what the flexible display, a paper-like computer display made entirely of plastic, could look like in the future."

Samsung concept phone unfolds to hypnotize onlookers with flexible OLED

by Chris Ziegler, posted Nov 24th 2008 at 2:01AM

Cellphones are caught in this awkward spot where they've got to be small -- like pocketable, doesn't-look-ridiculous-on-your-face small -- and yet somehow big enough to pack an expansive, pretty display that's capable of displaying a lot of stuff at once. That's a paradox that has forced manufacturers into some curious form factors over the years, but ultimately, if you want to somehow cram the desktop viewing experience into a device the size of a pack of cigarettes, you're probably going to need something that projects, rolls, or folds. That's where Samsung's new concept phone shown off at the FPD International show in Yokohama comes into play, opening like a book to reveal a flexible OLED big enough to handle those cute puppy videos that no plain-vanilla, 2.5-inch display can do justice. There's no word on when a so-equipped handset might see production -- but we think it's appropriate that it's being shown off in Japan in all places, if you catch our drift. Follow the break for a video of the display in action.

Another flexible circuit project emerges, carbon nanotubes to blame

by Paul Miller, posted Aug 8th 2008 at 5:56PM

Yeah, we get it, flexible electronics -- sans application -- are about as exciting as the circuitry under your keyboard. But it's Friday, and this here story has real-live carbon nanotubes, so you know it's a winner. Takao Someya of the University of Tokyo has built for himself a stretchy, flexible conducting material using carbon nanotubes mixed with a polymer. The nanotubes are mixed into a compound called "bucky gel" to prevent clumping, and after some rubber-like flourinated copolymer is mixed in and it's all poured onto a glass plate, holes are punched in the material to better flexibility. Apparently it ends up looking a bit like a nylon stocking, but we won't hold that it against it, since it can be stretched up to 38%, while also managing to be 100 times more conductive than any other elastic material. The possibilities for such technology is pretty much endless, but we'd say "nylon stocking that is also, conveniently, a computer" is the first product category worth felling.

E Ink fits Vizplex displays into Casio, Hitachi handsets

by Darren Murph, posted Aug 3rd 2008 at 1:17PM

For those still thinking that flexible displays are far from being widely accessible, think again. E Ink has just announced that its Vizplex Imaging Film-based displays will be used in handsets by Casio Hitachi Mobile Communications. For starters, the Hitachi W61H (already available) boasts a 2.7-inch E Ink display that can scroll through 96 different images whenever a call is received or the clamshell is cracked open; the Casio G'zOne (shown after the jump) will feature the same technology on its secondary "silhouette display." Details beyond that are pretty scant, but the real news here is that these displays are finally making their way into reasonably affordable handsets. Open up the flood gates, we say.

Networks of carbon nanotubes find use in flexible displays

by Darren Murph, posted Jul 25th 2008 at 12:54AM

Carbon nanotubes may very well kill you (okay, so that's very much a stretch), but you'll have a hard time convincing the dutiful scientists at the University of Illinois at Urbana-Champaign to stop their promising research. Put simply (or as simply as possible), said researchers have discovered that "networks of single-walled carbon nanotubes printed onto bendable plastic perform well as semiconductors in integrated circuits." So well, in fact, that the nanotube networks could one day "replace organic semiconductors in applications such as flexible displays." Granted, there is still much to do before these networks are ready for product integration, but you can bet these folks aren't hitting the brakes after coming this far.

Shinoda Plasma shows off slim, lightweight 43-inch display

by Darren Murph, posted Oct 4th 2007 at 8:16PM

Shinoda Plasma, a venture company spun from Fujitsu, was busy demonstrating a unique 43-inch panel at CEATEC that sports a pixel pitch of three-millimeters and is currently in prototype form. Reportedly, the device is made of "plasma tubes aligned and sandwiched between film-form electrodes," and it is based on the "same light-emitting theory as existing PDP technology." A boon to this, however, is its ability to be made much slimmer and lighter than current alternatives, as the flexible panel on stage was said to be one-millimeter thick and weigh just 1.76-pounds. Check out more pictorial delight after the jump.

Brando's illuminated, flexible keyboard ain't too pretty

by Darren Murph, posted Sep 23rd 2007 at 3:14PM

We'll admit, we can't recall seeing a rollable silicon keyboard that deserved to be called gorgeous, but Brando's iteration isn't even close. 'Course, those enamored with glowing lights and plastic-y gizmos may not find much room to grumble, but all aesthetics aside, this thing is reportedly "strong, silent and indestructible." Moreover, the $27 device is said to be dustproof and water-resistant, can be connected via USB or PS/2 and comes in white, pink, blue and green.

Flexible displays created by stretching crystals

by Darren Murph, posted Aug 24th 2007 at 6:18PM

As researchers continue to forge ahead in their quest to create commercially viable flexible displays, a new team from Canada has apparently unearthed a breakthrough of sorts. Reportedly, the crew has been able to conjure up a full-color display which boasts pixels made from photonic crystals, and by "bonding them to an electroactive polymer that expands when a voltage is applied to it," the colors of the pixels change. According to André Arsenault of the University of Toronto, the newfangled devices "can be viewed just as well in bright sunlight as in indoor light," and if all goes as planned, we could be seeing a whole lot more of these promising units "in as little as two years" when the startup Opalux looks to fit these bendable creations into billboards, handheld gadgetry, and anything else it deems fit.

Researchers develop bendable, paper-based battery

by Darren Murph, posted Aug 14th 2007 at 12:43PM

Nah, the researchers at Rensselaer Polytechnic Institute won't be crowned the first to develop a flexible (or paper-based, for that matter) battery, but their minuscule prototype "is an integrated device, not a combination of pieces" as others typically are. The battery uses "paper infused with an electrolyte and carbon nanotubes that are embedded in the paper," and could eventually be utilized in combination with solar cells or "scaled up and shaped into something like a car door, offering moving electrical storage and power when needed." Currently, however, the wee samples can release just "2.3-volts, or enough to illuminate a small light," but the idea of using these things to power pacemakers and the like isn't that far fetched.

Sony's world's first 16.7 million color flexible OLED

by Thomas Ricker, posted May 24th 2007 at 9:29AM

Oh boy, another bendy display we won't likely see on the market any time soon. This time it's Sony's turn to tout with this, their 2.5-inch, 160 x 120 pixel OLED display on a flexible plastic film. Better yet, this organic TFT delivers a relatively stellar 16.7 million colors compared to the 262k and 16k colors Samsung and LG.Philips, respectively, were showing off last week. That's a world's first 24-bit color depth for these types of displays. Take that Samsung. The display also measures a mere 0.3-mm thin which easily bests the hapless Korean (and Dutch) giants. The only downside (if you call it that) is the display's "greater than" 1000:1 contrast ratio compared to Samsung's 10,000:1 rating. But by now you've learned to take contrast measurements with a grain of salt, right?

Conceptual Flexi PDA boasts rubber hinges, flexible display

by Darren Murph, posted May 16th 2007 at 5:19PM

Just as Dell calls it quits on the PDA market and flexible displays become more and more common, it makes sense to see a concept device that takes advantage of both opportunities. The Flexi PDA, although still stuck on the drawing board, would present a rubber hinged handheld that could fold open much like a book, giving users a device that's a bit smaller and deeper than current alternatives. Additionally, the casing could easily be ruggedized in order to add water, dust, and shock proofing abilities for those with less delicate work spaces. As expected, this novelty would also pack a QWERTY keyboard, double as a cellphone, and triple as a media player should it ever hit the market, but for now we'll just have to settle with the above picture and a faint hint of hope.
