    Corning's Lotus Glass promised a world full of thinner, more advanced mobile displays when it was unveiled in 2011, but it hasn't always been easy to build with the volumes or features that customers want. Enter the company's new Lotus XT Glass as the solution: clients can produce it more reliably at high temperatures, leading to more usable panels for our LCDs and OLEDs. The improved yields should not only result in larger device volumes than the original Lotus Glass could muster, but push the technological limits -- Corning notes that hotter manufacturing allows for brighter, sharper and more efficient screens. The glass is commercially available today, although we'll still need to wait for gadget makers to choose, implement and ship it before we notice the XT difference.

    Samsung has finally started to reveal its new products at MWC 2012, starting with this refresh of the Galaxy Beam packing Android 2.3 and a 1GHz dual-core CPU. Just like its predecessor it brings an integrated projector capable of 15 lumens of brightness, enough to shoot a high definition image that's up to 50 inches wide. There's a dedicated app that activates the projection, letting users pump out video and pictures, as well as interact with games when the 4-inch WVGA screen just isn't big enough. It has a 2000 mAh battery to keep the party going -- handy when you're stuck somewhere inconvenient with a few dozen of your coworkers -- 8GB of built-in storage and a claimed 6GB of RAM (we're double checking that, consider it a likely typo until you hear otherwise). There's more details and specs in the press release after the break, but no word on release date or market availability of this HSPA phone just yet.Update: We've just confirmed that the Beam isn't loaded with a whopping 6GB of RAM as we initially reported. As it turns out, the device is actually packing 768MB of RAM (which is 6 gigabits, by the way). You can check out our hands-on with the device here for more details.

    There's nothing better than unplugging on a Sunday afternoon with a newspaper and a cup of Joe, which is exactly what AU Optronics hopes to facilitate with its 6-inch Rollable Organic TFT E-paper. We've heard rumblings about the foldable photovoltaic device before, but the company has finally delivered a working prototype that is completely solar powered and elastic enough to make even Gumby jealous. Made of organic TFTs, the SVGA e-paper has an amorphous silicon PV battery, which turns natural or indoor light into solar energy without requiring a power plug. The only downside? Unlike the dead tree variety, wrapping presents in this stuff is a no-go. Check out the extended PR after the break.

    With barely a few weeks before the phone giant's annual hurrah, Nokia World, kicks off in London, details have leaked of a new phone possibly winging its way to the Finnish faithful. According to MyNokiaBlog, the 710 is slightly longer and wider than the MeeGo-powered N9, with a 1.4GHz Cortex A8 processor, a 3.7-inch TFT screen and a five megapixel camera topped with some 720p video-capture frosting. All these details were swiftly pulled from the site, but not before the blog managed grab the screenshot above. A Nokia 710 also made a brief appearance on Occasional Gamer, which registers phone use on WP7 games. Most of the details match up with the Nokia Sun we saw earlier this month, though there are some inconsistencies -- is it TFT or AMOLED? We're hoping for the latter. It'll be a few weeks before Nokia has anything official to say, but whatever it is, it's going to have to wow us. The competition's never been tougher.

  • Hitachi's 4.5-inch IPS HD display delivers 329ppi on the cheap courtesy of amorphous silicon backplane

    It's been awhile, but earlier this year Hitachi unveiled a beautiful new 4.5-inch IPS LCD sporting 1280 x 720 resolution, a 1,100:1 contrast ratio and a retina display-like 329ppi. Well, in the time since, Hitachi's been hard at work on a virtually identical version of that screen that uses amorphous silicon instead of low-temperature polysilicon (LTPS) as its backplane material. What's the difference? Well, amorphous silicon's much cheaper to produce than LTPS, and the company figured out a way to use it in its new panel with only a scant drop in performance -- the new one's got a lower 1,000:1 contrast ratio, but all the other specs are the same. So, the screen's a comparative bargain while still providing 4.5 inches of 500-nit HD goodness. Thanks, Hitachi, we always did like eating our cake and having it too.

    Despite its rather curious name, the LG Optimus EX (aka the LG SU-880) just might be your soulmate -- provided you live in South Korea. The 9.5mm device appears ready to take SK Telecom by storm with a 1.2GHz dual-core CPU (with no indication of make or model), Android 2.3, 4-inch WVGA TFT-LCD display and five megapixel camera; it's also said to be coming in black and white varieties. We admit, it's not the type of spec sheet that induces a large amount of salivation, but we imagine many will be seduced by the new device -- if the price is right, that is. No word on pricing or availability yet, but we'll hopefully know more once we get officially introduced to the new handset.

    Primed goes in-depth on the technobabble you hear on Engadget every day -- we dig deep into each topic's history and how it benefits our lives. Looking to suggest a piece of technology for us to break down? Drop us a line at primed *at* engadget *dawt* com. The quality of a mobile phone's display is arguably the most important factor to consider when you establish a relationship with a handset. It's inescapable, really. Whether you're playing a rousing game of Robot Unicorn Attack or (regrettably) drunk-dialing an ex, it's the one interface element that you're consistently interacting with. It's your window to the world and your canvas for creation, and if it's lousy, it's going to negatively influence everything you see and do. Today, we're delving into the world of mobile displays, where we're aiming to entertain and edify, and hopefully save you from making regrettable decisions -- when it comes to purchasing new phones, anyway. In this edition of Primed, we'll be examining the different qualities and underlying technologies of several displays, starting with the ubiquitous TFT-LCD and moving through the nascent realm of glasses-free 3D and beyond. We'll also be addressing the importance of resolution and pixel density. Finally, we'll be scoping out a handful of upcoming technologies -- while some are thoroughly intriguing, others are just plain wacky. Go ahead... buy the ticket, take the ride, and join us after the break. It's Primed time.

  • Sony's new OLED display promises higher quality images, glitch-free brightness

    It may not be as flexible as some of the other displays we saw at last week's SID conference, but Sony seems confident that its new OLED panel will deliver high quality images with enhanced, glitch-free brightness. The 9.9-inch screen transmits images in 960 x 540 resolution, boasts a ninety-six percent color gamut, and is powered by a Self-Aligned Top-Gate TFT (in which the gate material is placed above the insulator) that reduces disparities in luminosity. To achieve this, Sony developed a new, four-part manufacturing process that lowers the parasitic capacitance between the gate electrode and the TFT. The top-gate structure, moreover, shortens the TFT's channel length, making it easier to adapt the technology to larger, high-resolution displays. No word yet on when the prototype will hit the market, but when it does, it'd be nice if it's priced as reasonably as some other OLEDs from Sony.

    E-reader manufacturers are doing their darnedest to get their devices to behave more like the old fashioned books we've all since abandoned, but we won't be happy until we can roll one up and stuff it in our back pockets, paperback-style. Sony's working hard to make that dream a reality -- the company showed off some new bendable display technology behind closed doors at last week's SID conference in LA, including a color unit and the extremely flexible black and white e-paper display seen above, which can be bent to a 5mm curvature radius. The 13.3-inch sheet has a 1,600 x 1,200 (150ppi) resolution and is powered by organic TFTs. Sony showed off and bent the thing at the show, reportedly to the cheers of the crowd in attendance. Clearly they're all as excited as we are to make some really expensive e-paper airplanes. For more shots of the bending process, consult the source link below.

    Samsung's Super AMOLED may have beat Toshiba to the in-cell capacitive touch punch, but we're still happy to see other LCD panels dropping unnecessary layers. Featured in a GPS mock-up, Toshiba's 7-inch 1024 x 600 R&D display touts 10-point multi-touch over 38,400 sensors -- that's one touch sensor for every four pixels. It may not be the first LCD to abandon the standard touch layer for integrated capacitive support, but we wouldn't shy away from a tablet or embedded screen featuring this 1mm wonder. We'll have to wait though; Toshiba's in-cell tech is still in R&D, with no word when or if we might see it in commercial devices.

  • Toshiba reveals 7-inch LCD with integrated touch, just 1mm thick

    Remember all that happy fuss over Samsung's Super AMOLED display, and its more recent Super AMOLED Plus? Well now Toshiba Mobile Display has jealously stepped into the ring with its own answer to the world's demand for thinner, lighter and less reflective LCDs. Its as-yet-unnamed technology seeks improvement in a roughly similar way to Super AMOLED, by fusing the capacitive touch layer and LCD. In so doing, Toshiba claims it can produce an integrated panel just 1mm thick, which it says is less than half the thickness of a conventional LCD touchscreen. Weight is also halved and surface reflection is reduced by 10 percent. Alas, Toshiba's press release does not provide the stats we really want -- a head-to-head comparison with Samsung's best efforts or, say, the Synaptics ClearPad 3250 which also melds touch layer and LCD. And perhaps to avoid confrontation in the mobile arena, Toshiba emphasizes the use of its technology in "vehicle-mounted" and "industrial" applications. Seems we will have to wait until the screen is exhibited in LA next month before we know whether it is really up for a fight.

    Look, we know you know all about LED backlights, light diffusion, subpixels, and the things that turn them on, but not everybody does. The humble LCD you're most likely reading this on still retains a level of mystery about the nitty gritty details of how it works for the vast majority of its users, so here's a terrific video breakdown of both its component parts and method of operation. Bill Hammack, a self-appointed Engineer Guy, takes us from the LED arrays that provide the light for most current LCDs, through all the filters and diffusers designed to make that light uniform, and into the ways thin film transistors make it possible for us to show moving color images of cats diving into boxes on such displays. It's exciting, deeply nerdy stuff, and it awaits your audience after the break.

    If you're a numbers geek, you're trying to be scientific about your next smartphone purchase, or you just like pretty colors, you might appreciate DisplayMate's latest report rounding up examples of all (well, most) of the latest and greatest display technologies out there: IPS LCD, Super AMOLED, AMOLED, and TFT, represented by the iPhone 4 and Droid, the Galaxy S, the Nexus One, and the iPhone 3GS, respectively. Noticeably missing is SLCD, the technology HTC has been using to make up for lost ground on its AMOLED shortage from component supplier Samsung, but we've got a hunch DisplayMate's hard at work at adding that into the mix. Anyhow, considering the sheer number of variables the firm takes into consideration -- everything from color depth, to brightness, to reflectance, to color gamut -- there's no clear-cut winner, but the Droid and iPhone 4 are obviously a cut above the rest with generally higher scores and better performance across the board. The Galaxy S' Super AMOLED turns in a decent performance, too, but takes a little hit for its 16-bit color depth and blown-out colors. Of course, if you consider any of these -- even the crappy TFT on the 3GS -- to a phone from five years ago, it still looks like science fiction... so you really can't go wrong, can you?

  • Samsung excuses absence of Super AMOLED on Galaxy Tab with Super TFT (video)

    A Super AMOLED 7-inch tablet was highly unlikely to ever materialize in a marketable form, but that didn't stop many of us from dreaming about one. Consequently, there was palpable disappointment when Samsung failed to deliver on our unicorn hallucinations with the Galaxy Tab, but the company says not to worry. The Tab's 7 inches of glorious visuals are being handled by a Super TFT panel, surely the Korean company's answer to Sony's Super LCD. It's a screen technology that has been developed "alongside" Super AMOLED and just so happens to offer better battery performance and an obvious saving in cost. We're usually inclined to consider such moves cynical marketing ploys -- keep the Super branding, drop the actual super hardware -- but the SLCD display on the HTC Desire gives us faith that perhaps TFTs really can be souped up.

    It's not every day we get to cite an official US Department of Justice news release, so it's with a certain glee that we can announce the US taxpayer was last week enriched by another $220 million courtesy of the not-so-fine folks who swindled him out of that money in the first place. Joining the ignominious ranks of LG, Sharp, Hitachi and Chungwa Picture Tube, Taiwanese manufacturer Chi Mei is refunding the US state for the pecuniary impact of its collusive practices, which were primarily related to keeping prices artificially high and profits proportionately inflated. US companies directly affected by these ignoble activities include HP, Dell and Apple, but don't you worry, AT&T has already started the inter-corporation scuffle, with Nokia piling on for good measure. Man, it almost seems like crime doesn't pay.

    As a leader in home cinema systems, it's always a good idea to keep tabs on Epson's core technologies as a preview of what's coming up in next generation home theater projectors. Today Seiko-Epson announced the start of volume production for its 0.94-inch HTPS-TFT LCD capable of a WUXGA (1920 x 1200 pixel) resolution for 3LCD projectors pushing 1080p. The panel supports a brightness of 5000 lumens (or more!) using Epson's D7 process technology while achieving "higher than ever contrast" through its C2 Fine inorganic alignment layer tech. What this means is simple: expect to see a new brightness and contrast champion PowerLite Home Cinema projector announced at the end of Summer, as CEDIA tradition dictates, with product shipping by end of the year.

  • Labor dispute with Apple display supplier intensifies

    After gathering in front of Apple's offices in Taiwan earlier this week, protesters are now demanding a substantive response from Apple by the end of the month regarding alleged workplace labor and safety violations at Wintek, one of Apple's display component suppliers. Labor groups associated with the protesters claim that Wintek unlawfully fired 619 workers, cut salaries without negotiation, and forced employees to work overtime without pay to fulfill rush orders. The company has since re-hired 20 of those workers and says it is operating within the law. Wintek has also threatened legal action if "company and stakeholder interests" are jeopardized. Wintek further claims that labor groups are violating their agreements and encouraging workers to demand benefits illegally. The protesters appear to be using the popularity of Apple's brand name to get attention to their cause. "We want to go through Apple to put pressure on Wintek," said Chu Wei-li, secretary-general of the Taipei-based National Federation of Independent Trade Unions. Apple Asia released a tepid response after the protests. Spokeswoman Jill Tan said, "Apple conducts regular audits of suppliers to make sure they comply with Apple's code of conduct. We require corrective actions when we find violations." An audit is exactly what aggrieved Wintek employees say they are demanding. MacNN says that rights groups associated with the protests are also asking the Electronics Industry Citizen Coalition to investigate Apple's delay in responding to the matter. Wintek was recently rumored to be the winner of the display contract for Apple's "media pad" tablet device. Some analysts predict the tablet will go on sale next year. Apple has previously found itself in the middle of other labor disputes. In 2006, Foxconn workers protested low pay and poor working conditions while assembling iPods. Apple conducted its own investigation and found that the company violated overtime rules and unreasonably punished workers. Since then, cute pictures of Foxconn employees have thawed the image of the supplier.

    USC researchers have demonstrated a low-temperature (and therefore relatively inexpensive, apparently) process for printing transparent TFTs on flexible material able to bend up to 120 degrees which allows for embedding LED to build see-through displays. The prototype disc shown above is 5 inches in diameter and contains around 20,000 nanotube transistors. The researchers suggest the technology could be used for e-paper, smart tags, and artificial skin, as well as an affordable heads-up display that could be put into car windshields. Our suggestion? Couple it with transparent playing cards for the ultimate poker-cheating experience.[Via OLED-Display]

  • Epson Imaging Devices introduce a-TFT displays that play well in sunlight or darkness

    Epson's developed two transflective amorphous silicon TFT (a-TFT) LCDs for high visibility in a variety of situations on mobile devices. The screens seem to have been developed mostly for gadgets which are used outdoors and in direct sunlight. These new LCDs employ a more traditional, transmissive mode, using backlighting in darker or indoor settings, but are also capable of utilizing a reflective mode, which can harness bright sources such as sunlight to increase clarity. The reflective mode not only increases visibility on the screen, but also reduces the need for backlighting, thus conserving power. The displays will be available in 3 and 3.5-inch sizes, and samples of the screens are said to be shipping before the end of the month.
