Bridgestone announces flexible touchscreen color e-reader

by Joseph L. Flatley posted Oct 27th 2009 at 9:54AM

When we heard word of a "big announcement" back in July we imagined an e-reader of some sort, but what is it that we have here? Based on a technology Bridgestone calls Quick-response Liquid Powder, the company's all-color touchscreen e-book reader is about 5.8mm thick, features a 13.1-inch touch-sensitive e-paper display (with 4,096 colors and a refresh rate of about 0.8 seconds), and some sort of unspecified mobile phone connectivity. Most exciting, of course, is that the entire package -- circuit board, touchscreen, and housing -- are designed to bend together. A neat trick, sure, but probably not too practical for jotting down notes with your stylus. Still, we'd take two. Trials begin at the Kansai Urban Banking Corp early next year, but you can check it out sooner at FPD International 2009 in Yokohama City, Japan, starting tomorrow.

AUO demonstrates 6-inch flexible electronic paper, pledges production for next year

by Tim Stevens posted Oct 20th 2009 at 7:29AM

If e-paper is ever really going to have a chance against tree-paper it's going to have to get a lot more flexible. We've seen multiple demonstrations of bendable wares from LG and even big daddy E Ink, but AUO is the first to pledge mass production of the stuff (since the Readius went bust), starting in 2010. The company has demonstrated a 6-inch flexible display offering 16 shades of gray and a contrast ratio of 9:1, which sounds terrible but is actually slightly better than the Kindle's 7:1. The company is also showing off a 20-inch non-bendy version that should also hit production sometime next year. When will either get the hammer treatment? That remains to be seen.

Ask Engadget: Best flexible keyboard out there?

by Darren Murph posted Jul 23rd 2009 at 9:03PM

We know you've got questions, and if you're brave enough to ask the world for answers, here's the outlet to do so. This week's Ask Engadget question is coming to us from Jeremy, who is desperately searching for a portable and malleable keyboard to take on the road.

"I love my little computing companion but I often find myself missing a full sized keyboard. I have been looking at several of these portable and flexible keyboards, but I can't seem to make up my mind about which I should buy. I don't want the keyboard to be overly expensive, but I want it to be good quality. Also, how difficult is it to type on these keyboards? Thanks!"

To anyone who has been forced to use a cramped netbook keyboard for over a few minutes, you know how dire the situation can get. If you've literally rolled a keyboard into your arsenal, let us know which one made the team and how it's holding up.

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.
