Sharp's new display shows the pixel-density race is far from over
If you have spectacularly good eyesight, the highest pixel-density you can see is about 500 pixels-per-inch (ppi). But that trifling little detail isn't stopping display manufacturers and marketers, no sir! Sharp just revealed an iPhone 5s-sized (4.1-inches) IGZO LCD screen with WQXGA (2,560 x 1,600) resolution. That works out to 736ppi -- a quantum leap above Samsung's Galaxy S5 LTE-A, the current smartphone champ at 576ppi. You'll see devices with the screen starting in 2016, but it may lose its density crown before then anyway. Samsung is rumored to have a 5.9-inch, 4K Super AMOLED display with 747ppi in the works. Better eat those carrots. Update: We've updated the post to note that it's the iPhone 5s that has a 4-inch-sized screen, not the iPhone 4s.
Android 4.3 source code reveals support for 4K resolution
We've seen Android run on anything from low-resolution smartwatches to high-PPI phones and tablets, including the new 1920 x 1200-pixel Nexus 7 Google launched earlier this week. To make this possible, the mobile OS supports a number of pixel densities for app content -- from 120PPI (LDPI / Low DPI) to 480PPI (XXHDPI / Extra Extra High DPI). Close examination of the Android 4.3 (Jelly Bean) source code reveals the addition of a 640PPI (XXXHDPI / Extra Extra Extra High DPI) pixel density, which -- according to the comments in the code -- is intended for 4K televisions. Does this mean we'll begin to see Android devices with 640PPI Ultra HD displays? Perhaps, but considering 480PPI is overkill on handsets, this is most likely designed to make image assets and fonts, such as the Google TV UI, readable on 4K screens when viewed from a distance.
Sharp begins production of 1080p smartphone displays: 443ppi crammed into a 5-inch LCD
Layoffs and loans may be dominating our Sharp coverage at the moment, but that just makes this type of news all the sweeter. The company has announced its LCD panel type 5 -- a 5-inch full HD (1,920 x 1,080) display packing a Retina-busting 443ppi (just trumping LG's similar 440ppi LCD). An outcome of its layer-reducing CG-Silicon technology, the smartphone-targeted screen goes into full-scale production this month and will be shown off at CEATEC Japan this very week. We'll try to give it eyes-on treatment at the show, but you can rub your hands together sinisterly in the meantime and just think about the glorious devices which will bear it.
Microsoft seals Perceptive Pixel deal, welcomes PPI team to the Office Division
In case you haven't noticed, Microsoft's been in a blissful shopping mood lately -- and while we already knew the company had snatched up the creator of that enormous 82-inch touchscreen, today's the day a more formal introduction is taking place. Via its Official Microsoft Blog, the Redmond-based outfit is suitably welcoming the Perceptive Pixel team aboard the Office Division, also announcing that PPI's Founder, Jeff Han, will be joining as a "general manager" and reporting to Kurt DelBene. Naturally, we're still wondering what exactly the acquisition will bring to the table, but if Perceptive Pixel's previous doings are any indication of what's to come, we can expect some more delightful novelties to come out of Microsoft's HQ in the hopefully-not-so-distant future.
JDI debuts 2.3-inch display with a 1,280 x 800 resolution, 651ppi
Well, it looks like LG's Retina-beating 5-inch display with a 1080p resolution isn't the only screen setting some new pixel density records at the SID conference this week. Japan Display Inc. has now also announced a new 1,280 x 800 display with an amazing pixel density of 651ppi. If you're able to do the math, though, you'll realize that means the display itself measures just 2.3 inches. While it's not clear exactly what sort of devices JDI has in mind for the screen, the company says it's able to produce photographic-level images and text that is perceptibly sharper than even today's highest-resolution displays -- hopefully we'll be able to judge that for ourselves sooner rather than later.
Kyobo, Qualcomm make Mirasol color displays a reality, with the Kyobo eReader
Don't look now, but Mirasol has just arisen from the dead. Today, Korea's Kyobo Book Centre and Qualcomm jointly unveiled the world's first Mirasol-coated e-reader, just a few months after CEO Paul Jacobs heralded the demise of his company's color e-paper format. The device, known as the Kyobo eReader, sports a 5.7-inch, 1024 x 768 color display with 223ppi and touchscreen capabilities, runs Android 2.3 and is powered by a 1GHz Qualcomm Snapdragon S2 CPU. Kyobo says you'll be able to use the WiFi-enabled slate for "weeks" on a single charge, as long as you do so at decreased brightness, and for a total of 30 minutes per day. The eReader is available now for around $310, but only in South Korea. There's no indication that it'll be making its way to other markets anytime soon, but in the meantime, sate yourself with a portion of PR, after the break.
HTC Rezound review
The Motorola RAZR and Samsung Galaxy Nexus seem to be the two Verizon LTE juggernauts enjoying the lion's share of the spotlight, with the HTC Rezound sandwiched smack dab between the two of them. But that doesn't mean the device has any less to offer -- you might even say it's entitled to some bragging rights. It's not the thinnest phone, nor does it have Ice Cream Sandwich (yet), but being the first carrier-branded handset in the US boasting a 720p HD display should carry a lot of weight. The Rezound -- as you might have gathered from the name -- is also the first HTC gizmo in the States to integrate Beats Audio. So does it fare well against its LTE competition? Is it enough to take your mind off of the Nexus? Read on below to find out. %Gallery-139234%
Toshiba shows off 6-inch tablet display with 498ppi resolution
Toshiba showed off a 4-inch display for cellphones with a 367ppi resolution earlier this year, and it's now back with an even higher pixel density for its new 6.1-inch display for tablets (or possibly phones, at the rate things are going). This one comes in at an impressive 498ppi, which translates to a resolution of 2,560 x 1,600 -- or more than enough for some "photo-realistic" images, according to Toshiba. As for the other key specs, it boasts a 1,000:1 contrast ratio, 16.7 million colors, and 61 percent coverage of the NTSC color gamut -- plus viewing angles of 176 degrees both horizontally and vertically. What's more, Toshiba is even suggesting that the display could also be used for glasses-free 3D, which would cut the resolution in half but still be higher than other comparable displays. Unfortunately, there's no word on when it might actually hit some tablets, 3D or otherwise. Head on past the break for an up-close look at those pixels.
Engadget Primed: all mobile displays are not created equal
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.
Android Honeycomb has hidden Gingerbread interface, enabled by higher LCD density
Google's already indicated that tablets and smartphones won't be sharing the same Android build until Ice Cream Sandwich in Q4, though interestingly enough, it turns out that the tablet-friendly Honeycomb actually has Gingerbread's interface quietly tucked underneath. According to modder Graffix0214, all you need for making the jump is one simple tweak in a system file: assuming you already have root access, use your preferred method -- Pocketables recommends the LCDDensity for Root app -- to change the LCD density value to 170 or higher to emulate a smaller, denser display. After a reboot, you should then see some Gingerbread love as demoed by Graffix0214's video after the break; and likewise, set the value to 160 or lower to roll back. It sure is nice to have an option, eh?
Sharp shows off the world's first Super Hi-Vision 85-inch LCD with 16x more detail than 1080p
While Japan's NHK has been working on the successor to HDTV, Super Hi-Vision, for years, there haven't been any direct-view HDTVs capable of showing its full 7,680 x 4,320 pixel resolution until this prototype unveiled today by Sharp. Its 103 pixels per inch may be just a fraction of those found in some of the pocket displays we've seen at SID this week, but that's still far more than the 36ppi of a 60-inch 1080p HDTV. If estimates are correct, we'll still be waiting until around 2020 for that 33MP video and 22.2 channel sound to actually be broadcast, although there's a possibility of some demonstrations happening during the 2012 Olympics. Skip past the break for the available specs and a video demonstration, or just head over to the NHK's Science & Technology Research Laboratories in Tokyo between the 26th and 29th of this month.
LG's new ultra-high resolution AH-IPS displays, simply stunning at any size
The Life's Good gang warned us with the written word about its super fantastic, ultra-high resolution Advanced High Performance In-Plane Switching (AH-IPS) displays. Of course, written resolution claims merely provide verisimilitude; viewing is the only way to discern their veracity. We saw the screens, ranging from a petite 3.5 inches to a prodigious 84-inch panel, at SID 2011 and were impressed enough to begin scheming ways to get a wall of these for Engadget HQ. Unfortunately, we don't know how many dollars LG wants for its plethora of panels or when they'll go on sale, but you can bet we'll keep you posted. If our impressions and that mouthful of a moniker haven't sold you on the awesomeness of AH-IPS, then take a gander at the gallery and let the pixel-packed pics persuade you. %Gallery-123864%
Samsung and Nouvoyance show off power-sipping, pixel packed Pentile display (video)
Samsung is seriously stepping up its slate screen game with its 10.1-inch 300ppi panel that we told you about last week. We just got to see the display in person at SID 2011, and can confirm that the presence of Pentile pixels should no longer be a cause of concern. Nouvoyance, who designed the display, told us that the panel's RGBW pixel configuration makes your whites whiter and brights brighter (up to 600 nits worth), while consuming 40 percent less power than conventional LCDs. The company also told us the tech's been around for awhile, but that market forces conspired to keep it concealed -- though after seeing it in person, we can't fathom why it didn't make it into Sammy's stellar new slate. Pixel-density people shouldn't pout, however, as devices packing the display will drop by Q4 of this year or Q1 2012. Video explaining why you should join the RBGW revolution's after the break. %Gallery-123857%
Toshiba declares victory in pixel density war: 367ppi coming to a phone this year (video)
We got the lowdown on Toshiba's latest four-inch LCD a couple of days ago, and today at SID 2011 we got up close and personal with the pixel-packed display. It's one thing to read about a 367ppi screen that shows native 720p video, and it's quite another to experience it in person. We can report that it is, in fact, as awesome as it sounds -- onscreen images were clear, crisp, and chromatically brilliant. Pixel density enthusiasts will also be happy to hear that Toshiba confirmed the display will make it to market this year. Of course, the rep wouldn't tell us which phone will take the iPhone 4's crown as the ppi champ, though we imagine it'll be something powered by little green bots. See the new king in action in the video after the break. %Gallery-123856%
E Ink and Epson to co-develop 9.7-inch high-res 300ppi electronic paper display
It's pretty obvious that this year's SID Display Week is shaping up to be a stage for the 300ppi extravaganza -- Samsung and LG were first to announce their latest high pixel density LCDs, and then Toshiba chimed in with its 367ppi LCD for cellphones. Fortunately, fans of ePaper will also have something to look forward to here, as E Ink Holdings and Epson have just announced the co-development of a 300ppi ePaper display. To be exact, E Ink will be in charge of producing the sharp-looking 9.68-inch 2,400 x 1,650 display panel, whereas Epson will take care of the high-speed display controller platform to go with E Ink's part. No availability has been announced just yet, but stay tuned for our eyes-on impression at the show.
Toshiba enters pixel density fray with 367ppi LCDs for cellphones
Toshiba just fired its own salvo in the pixel density wars at SID 2011. The company is showing off a range of LCDs for cellphones that top out at an almost imperceptibly fine 367ppi on its 4-inch HD (720 x 1280) model. Beyond just cramming more red, green, and blue dots in each inch, these panels also top the bar-setting Retina Display in the contrast department with an impressive 1,500:1 ratio. The company also brought a smaller 3.3-inch screen with a resolution of 480 x 864 to Display Week that hits a respectable 300ppi. They're not quite as impressive as these HAST LCDs, but who really needs to put 1080p in their pocket? (Want is a different story.) Of course, Engadget is on the scene and, if you're lucky, we'll let you live vicariously through us as we tour Toshiba's booth -- you know, as a reward for your loyal readership.
Samsung and LG to showcase high pixel density LCD panels for tablets at SID 2011
It's a well-known fact that LG's already dominated the pixel density race in the smartphone market thanks to the Retina Display inside the iPhone 4, but we've yet to see similar technologies making their way to larger devices. That could change very soon, however, with Samsung and LG both announcing larger high-density panels to be showcased at SID 2011 next week. From Samsung we'll be seeing its 10.1-inch 300ppi prototype LCD panel, which rakes up an astonishing resolution of 2,560 x 1,600 under the battery-friendly PenTile RGBW matrix (not to be confused with AMOLED and Super AMOLED's RGBG arrangement). What's more, Samsung also teases "commercial availability" for this technology later this year. Things are a bit vague with LG -- no specific resolutions are mentioned in the pre-show announcement, but we're told that the company will introduce "a full line-up" of "ultra-high resolution" Advanced High Performance In-Plane Switching (AH-IPS) products, including 3.5-, 4.5-, 7-, 9.7, 55-, and 84-inch panels, with a "greater number of pixels than the PPI that can be recognized by the human eye at a typical distance" -- a proclamation typically reserved for the iPhone 4's 326ppi Retina Display. Of course, LG could be misleading here -- the 9.7-inch panel brought up in the press release could just be the exact same 1,024 x 768 IPS display on the iPad, but we'd be surprised if LG doesn't have a similarly-sized prototype to fire back at Samsung's 10.1-inch 300ppi panel. Well, keep an eye out for our SID 2011 coverage next week and we'll let you know what goodies we find.
Samsung sees a Retina Display in your tablet future, and perhaps glasses-free 3D
Samsung gazed into its crystal ball today, and what did it see? The pixel density of tablet screens drastically increasing. Yes, while Apple may not have managed to cram a screen into the iPad 2 worthy of the Retina moniker, it sounds like Samsung Semiconductor may be working on just such a thing, as the company projects that it will have tablet displays with 300 to 400 pixel-per-inch resolutions by 2015. Presently, the Samsung Galaxy Tab has a seven-inch, 1024 x 600 panel, which translates to only about 170ppi, but Samsung suggests that tablets of the exact same size might stretch well beyond 1080p desktop resolutions as pixel density increases, and yet still manage a respectable 8 to 10 hours of battery life. Samsung also said that while it's still waiting to see if consumers adopt stereoscopic 3D, it might be interested in joining the throng, perhaps bringing a glasses-free tablet display to market in the years to come. Curious what else the future might hold, according to Samsung? Take a peek at our gallery below. %Gallery-119627%
Analysis of iPad 2 display shows performance similar to iPhone 4
The iPhone 4's Retina Display rightly gets praise for its high pixel density. Since its release, many iPad owners have longed for Apple to bump up the display resolution from 1024 x 768 in order to provide a similar viewing experience on Apple's tablet. When viewing an iPad's display next to an iPhone 4's Retina Display, the iPad appears excessively pixelated, particularly in text-heavy apps like iBooks. Pixel density aside, recent analysis by Dr. Raymond M. Soneira of DisplayMate Technologies shows that the iPad 2's display stacks up well against the iPhone 4 in most other measures. According to Dr. Soneira, "the display on the iPad 2 delivers almost identical performance to the impressive iPhone 4 Retina Display," for the values he measured. Dr. Soneira compares the iPhone 3GS, iPhone 4 and iPad 2, and he analyzes values such as brightness, contrast ratio, black levels, and viewing angles to give us an idea of how Apple's newest device stacks up. In most respects, the iPad 2's display does indeed perform similarly to the iPhone 4, and both devices have measurably superior display quality compared to the iPhone 3GS. Although the iPad 2 display's 132 ppi doesn't compare favorably to the iPhone 4's 326 ppi, Dr. Soneira calls the pixel density on the Retina Display "overkill" anyway. He believes some of the iPad 2 display's shortcomings could be addressed in software; Dr. Soneira says "anti-aliasing on the iPad 2 is far from state-of-the-art and degrades the perceived sharpness of text and graphics." Indeed, comparing the anti-aliasing on an iPad display versus a notebook display with a similar pixel density shows the iPad suffers from greater pixelation. Some iOS developers, such as Firemint and Chair Entertainment, have already taken advantage of the iPad 2's better graphical performance, and using techniques similar to the ones Dr. Soneira advocates, these developers have delivered superior-quality graphics in their apps even though the display resolution remains the same. With its limited RAM and less powerful A4 processor, it's possible the original iPad lacked the processing power necessary to support anti-aliasing similar to that accomplished on Mac displays, but the iPad 2 should be able to do so. Perhaps improved anti-aliasing for the iPad 2 is something we should add to our wish list for iOS 5. [via AppleInsider]
Ortustech unveils world's smallest Full HD display, puts Retina to shame
Ever heard of Ortustech? Probably not. But you have heard of Casio, right? Ortustech is a joint venture between Casio Computer and Toppan Printing to develop small and medium sized displays. Today, the company is announcing a doozy with its 4.8-inch 1920 x 1080 pixel HAST (Hyper Amorphous Silicon TFT) LCD with 160-degree viewing angle, 16.8 million colors, and a pixel density of 458ppi. Amazing when you compare that to the lauded 326ppi of iPhone 4's Retina display. However, it still pales in comparison to that little 546ppi panel Casio announced back in 2008 which we still haven't seen put into a consumer product. Doesn't bode well for this one being made available anywhere other than the trade show circuit.
