NHK's flexible OLED is both literally and figuratively green (video)
When it's not pushing Super Hi-Vision, the hopeful 7,680 x 4,320 successor to HD, NHK also dabbles in small, flexible OLED panels. The Japanese public broadcaster recently showed off a 5-inch prototype display that, while bearing a heavy green tint and very noticeable rows of dead pixels, was still a significant improvement over a similar screen it demoed in 2009. Sure, it's not quite as flexible or vibrant as Sony's rollable OLED from last year, but it does seem to suffer from fewer bad pixels -- an important step towards maturation. Don't miss the video after the break which offers some pretty nifty glimpses at a number of bendable OLEDs. It's clear the tech is still a little wet behind the ears, but we're definitely getting closer to a future populated with TVs that roll up for storage and e-readers that fold like a paperback.
NanoPhotonica develops S-QLED, OLED to develop inferiority complex soon
Ahh, the wonders of OLED -- flexible displays, great viewing angles, and low power consumption. However, the folks at NanoPhotonica have "perfected" a quantum dot display technology called S-QLED that allegedly has superior picture quality, uses 30 percent less power, and costs three-quarters less than its OLED competition. The company is gearing up for mass production and is in talks with several OEMs to start producing S-QLED displays, but unfortunately there's no timetable for when they'll get to market. Guess we'll have to wait a bit longer to see just how perfect these QLEDs really are.
IMEC creates flexible microprocessor with organic semiconductors -- computational clothing right around the corner
Organic semiconductors have been teasing us with the possibility of computationally-inclined clothing for years, but until now we could only dream about our pants being the computer. That dream is closer to reality than ever, as researchers from IMEC have created a cheap (potentially 1/10th the cost of silicon chips), bendable microprocessor by layering a plastic substrate, gold circuits, organic dielectric, and a pentacene organic semiconductor to create an 8-bit logic circuit with 4000 transistors. Executing 6 instructions per second, these things won't be challenging Watson any time soon, but the chips should prove useful in creating cheaper flexible displays and sensors to tell us whether that week-old chicken in the fridge has gone bad. The trick was to overcome individual organic transistors' variable switching voltage thresholds -- as opposed to silicon's predictable nature -- that eliminated the possibility of organic-based logic circuits previously. But by adding a second gate to each transistor, IMEC was able to control the electrical field in each to prevent unwanted switching and usher in the dawn of plastic processors. The zenith of nerd fashion can't be far behind.
Samsung creates first full-color quantum dot display, threatens to make Dippin' Dots obsolete
We haven't been serving up quantum dots news for quite as long as we've been regaling you with tales of quantum computers, which is just as good because we're about to tell you the technology is still at least three years away from showing up in something you can buy. But, it is getting closer, with Samsung demonstrating a four-inch quantum dot display with full color. Quantum dots are nanocrystals that emit light when they get excited, perhaps on Christmas morning or when waiting for the list of school cancellations on a snowy morn. The size of the crystal dictates the wavelength of light emitted, and by laying precise grids of different sized crystals Samsung creates RGB pixels of the sort needed to make a display. Pixels can be applied directly to glass or to a flexible surface, and in theory they'll be far more efficient than an LCD while brighter and longer-lasting than OLED. Right now, however, they don't achieve any of those benchmarks, which is unfortunately where we circle back to the whole "three years away" thing.
Samsung buys Liquavista, dives headfirst into electrowetting displays
Samsung's got a reputation for building crazy awesome display technologies, and it just added another one to the stack -- with the buyout of Philips-spinoff Liquavista this December, it's gained quite the foothold in electrowetting. In case you're not familiar, electrowetting has been repeatedly pitched to us as pretty much the Holy Grail of displays: flexible, colorful, unbreakable, outdoor-readable e-paper screens with high refresh rates and low-power consumption that can be manufactured on existing assembly lines. We'll have to see if the theories equate to meaningful products, but we imagine ownership by Samsung can't hurt one bit, especially as the company says it will "expand its leadership in next generation display technologies by pioneering the application of electrowetting in e-Paper and transparent displays." Sounds like a commitment to us. PR after the break. Update: Seems that The Digital Reader actually figured out about the deal yesterday -- read the original scoop at our more coverage link!
ITRI shows off 6-inch FlexUPD AMOLED, hybrid 2D/3D display, makes lots of promises
Hey, remember when Taiwan's ITRI said that flexible TFT-EPD displays would be ready for smartphones by 2009? Yeah, well, keep that in mind when reading about this new 6-inch flexible display the company says will be released in a line of e-readers "very soon." It's called the FlexUPD, a 1mm thick AMOLED with a 5cm folding radius, 150nits brightness, and "unbreakable" construction. ITRI is also talking up its switchable 2D/3D display that we saw earlier, able to display both types of content simultaneously and do so without the requirement of goofy glasses. That tech is called i2/3DW and is set to "revitalize the [display] industry by revolutionizing the concept of 3D viewing." You keep on believing, ITRI, we'll just keep on waiting.
Liquavista displays get flexible, 'unbreakable,' still rather theoretical (video)
The next generation of display technology is still that, next, but despite being a future away it continues to get better. Liquavista keeps wowing us with various demonstrations of its electrowetting technology offering full color, high refresh rates, visibility in all lighting conditions, and low power consumption to boot. Now they're bendy too, with the company releasing footage of a prototype that's flexible. It's also said to be "unbreakable," demonstrated by a person wearing latex gloves gently tapping on the screen -- because, you know, that's about as tough as it gets outside of the lab. Video is after the break, along with full PR, but in neither will you find any hope of seeing this tech for real before the second half of next year.
LG putting 9.7-inch color, 19-inch flexible e-paper displays into production
LG's shown off plenty of display prototypes that may or may not ever wind up in actual products, but it looks like two of them are about to get real -- a recent SEC filing has revealed that LG is expecting to put both a 9.7-inch color e-paper display and a 19-inch flexible e-paper display into mass production by the end of the year. Details beyond that are expectedly light -- including any word on what type of products they'll be used in -- but the 19-inch display is apparently the same one we first saw back in January (pictured above). That could conceivably be used for a newspaper-sized device, or possibly things like digital signage, which might be a tad more likely given the constraints in tacking a touchscreen layer and other components on top of the display.
HP's McKinney hints that a flexible display Palm device could happen
Speaking at MobileBeat in San Francisco today, HP's Phil McKinney chatted up the company's flexible display tech, which uses rugged Mylar-infused sheets similar to those found in solar panels and can display video while still being bistable the same way E Ink is -- in other words, it'll hold an image without power. Thankfully, this seems to be more than a pipe dream sitting in a lab somewhere, because McKinney went on to say that "these are the kinds of display technologies that will change what we think of in form factors, both in products from Palm with flexible displays, and with HP." In other words, it's entirely within the realm of reason to imagine a bendy webOS device that gingerly sips battery juice -- or stops sipping it altogether -- while you're reading the morning news. We wouldn't expect it any time soon, of course, but it's encouraging to hear a conservative industry behemoth like HP start to talk like this. In the meantime, can we just get a new Pre, guys?%Gallery-97337%
Toshiba flexes its paper-thin LCD muscle, moves the world (video)
Toshiba's found an interesting use for flexible LCD technology: user input. At SID 2010, the Japanese display manufacturer showed off an 8.4-inch wide, 0.1mm thick SVGA panel that could be grabbed and physically bent to zoom in or out using Google Earth. While it's a far cry from 6DOF and perhaps not as entertaining as controlling the time-space continuum with forefinger and thumb, the bend sensor seems like an obvious addition to the gamut of crisp, rollable, data storing, energy generating flexible tech already in development. It's also worth noting that Toshiba isn't the only one working on the idea; IBM filed a patent application for "flexible displays as an input device" back in 2006. Video after the break.

E Ink shows off brighter, crisper, more flexible displays
It's easy to forget that E Ink is an actual company and not just a display technology, but the company was out in full force at the recent SID 2010 conference to remind folks of that fact, and show off some of its latest and greatest prototype displays. Chief among those is a new color display that promises crisper, brighter colors, though still not quite full color -- something that's apparently achieved by applying a filter on top of a regular black and white E Ink panel, which itself has blacker blacks and whiter whites than before. Also on display was a new "fully flexible" display (not color), and another black and white display that was apparently able to playback Flash video -- although E Ink curiously wasn't allowing anyone to film it in action. The folks from MIT's Technology Review did manage to capture a brief look at the rest of them on video, however -- hit up the link below for their report.
LG flexible display patent application includes fever-dreams of future devices
We're still a ways out from real-world applications of flexible displays, but LG is preparing for the future: it's just filed a patent application that details changing a flexible display's touch sensitivity depending on the state of the display, and it's included some intriguing drawings of potential devices with the application. Specifically, the patent application includes claims referencing cylindrical, prism, folding, "rolling," "freestyle," and "hybrid" body shapes, which all sound pretty intense -- especially the hybrid body, which is a "combination of the folding body and rolling body." Of course, patent applications don't always turn into granted patents, let alone shipping products, but if you're in the mood to stare wistfully at line art and dream about the future, the full PDF is at the source link.
HP flexible display unfurled on video
HP has been working on flexible displays for some time now, but it looks like things are starting to get a bit more real. Not real as in actual products, mind you -- but real like a big, flexible display spotted out in the wild. Doing the honors for this one is Hardware.info, which not only snapped shot above, but captured some of the action on video (head on past the break for that). Interestingly, HP doesn't actually see these panels being used in truly flexible or rollable displays -- the material itself would only survive being rolled up about a half dozen times -- but instead sees them being used to simply make displays thinner and lighter. [Thanks, Frank]
Nokia patent application points to flexible phone displays
It may still be quite a ways from realizing its ambitious Morph concept, but it looks like Nokia has been toying around with the idea of flexible displays as of late, as evidenced by a just-published patent application (first filed back in 2008). Covering a "user interface, device and method for a physically flexible device," the application details (among other things) how a flexible display might be used on a phone to do things other than make it more portable. Most interestingly, that includes bending the phone into a particular shape to perform a specific task -- Nokia suggests rolling it into a can to search for a bar or pub, or bending it into a bowl to search for a restaurant. Not exactly the most imaginative examples, to be sure, although we're sure Nokia will have plenty of time to come up with some more interesting uses before any such phones actually hit the market. [Thanks, Anand]
AUO demonstrates 6-inch flexible electronic paper, pledges production for next year
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.
Sony's CEATEC concept party includes Walkman bracelet and 0.2mm thin OLED (video)
We've yet to see a trade show where Sony left its Rhode Island-sized booth at home, and CEATEC is no exception. Aside from pushing its 1080p 3D installations with an epic amount of force, the company also had a smattering of swank new concepts on display that caught our eyes. A 0.2 millimeter-thin flexible OLED display was alive and displaying content, while an ultrathin Reader mock-up looked more like a MID and less like a Kindle. Without question, the two items that took our breath away were the all-panel laptop (which tossed the traditional keyboard in favor of a single, swooping display) and the Walkman bracelet, which did little more than talk dirty to us and get our imaginations working overtime. Unfortunately, all the good stuff was behind bulletproof glass with practically zero information to digest, but you can indulge your senses anyway in the gallery below and video after the break. %Gallery-74747%
LG Display showcases 11.5-inch flexible e-paper
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?[Via OLED-Display]
Resin replaces ITO in latest flexible OLED prototype
Make no mistake, wrapping your mind around the build of an OLED panel is mighty tough to do. Without getting you mired in technobabble, let's just say that indium tin oxide (ITO) has generally been a mainstay in every single OLED that was produced commercially. Now, a team of researchers from AGFA-Gevaert, IMEC, Holst Centre and Philips have prototyped a 12- x 12-centimeter flexible OLED lighting panel that swaps out the ITO for highly-conductive transparent resin electrodes. You see, it's been difficult for OLED builders to secure enough electrical conductivity of ITO in a low-temperature process, and this new methodology is perfectly suited for the coating method (which makes it ripe for printing). The resin itself is being dubbed Orgacon, and tests have shown it to have a 6x improvement over ITO in terms of electrical conductivity. Beyond that, the crews are keeping the secrets safe from the poachers of the world, but here's hoping this amounts to more than just jovial celebration in a far off laboratory.[Via OLED-Display]
Modistech unveils flexible, ultrathin OLED light in Korea
We just heard that the OLED market was set to skyrocket in 2011, but don't tell Modistech. Said outfit has just revealed its own flexible, ultrathin OLED light module in South Korea, which honestly looks eerily similar to Samsung's "flapping" OLED panels from last fall. Details are pretty scant right now, but we're told to expect mass production within the next year, with public availability penciled in for -- you guessed it -- 2011. Hit the read link for a few more delightful looks.[Via OLED-Display]
Sony shows off flexible OLED Walkman concepts on video
Looks like Sony Insider caught some footage of those flexible OLED Walkmans in action during a CES promo video hidden away in the booth. Looks like a pretty sweet riff on the Cover Flow-esque interface that's due to arrive on the NWZ-X1000, but there's not much else to go on -- let's hope Sony's spending more time getting the X1000 ready to leave that impenetrable glass housing than it is mocking up videos of fantasy tech. Video after the break!
