OLED’s failure to do anything for the mainstream so far outside of phone and camera displays is only bittersweet: sure, we don’t have millimeter thick TVs yet, but LCD has gotten slim enough that it hardly matters. So, in keeping with tradition, LG has stolen its own OLED thunder today. In line with earlier rumors, it will be showing off a 0.11-inch thick 31-inch 3D OLED display prototype at IFA this week, but that poor little OLED-that-would will be sharing a booth with a ready for retail 0.35-inch thick LCD that comes in big people sizes. Despite our undying affection for OLED, we know which one we’ll be (theoretically) taking home in the windowless van we (theoretically) plan on parking out behind the Messe Berlin.
Pixel density enthusiasts, pay close attention, because science is ready to blow your minds — the University of Michigan has developed an LCD technology that can display their logo in a space just nine microns high. By creating a filter made of microscopic metal gratings with differently sized holes just a few hundred nanometers wide, researchers discovered they could precisely capture wavelengths associated to red, green and blue light, producing pixels roughly eight times smaller than those in the iPhone 4’s famous screen, and entire images that could practically fit inside a single dot of Kopin’s microdisplay.
Meanwhile, OLEDs (which don’t require filters to produce their color) saw a nanotech breakthrough of their own last week, as a group at the University of Florida have discovered that carbon nanotubes can revitalize a once-inefficient but promising vertical stacking technique. Layering thin sheets of aluminum, carbon nanotubes, organic material and finally gold on top of a glass substrate, scientists have created OLEDs that promise to be cheaper, faster and require one-tenth of the power of those using polycrystalline silicon, and could theoretically be printed as a flexible display as well. Here’s hoping we’ll see the fruits of these fellows’ labors soon — we can’t wait to pen a follow-up to this epic fight.
The Pantech Vega that just hit Korea may boast a sizable 3.7-inch AMOLED screen, but don’t expect future phones from the Helio manufacturer to follow suit — after suffering the same shortages that drove HTC to Sony’s SLCD-illuminated doorstep, Pantech’s also temporarily giving active-matrix organic technology the boot. Now, you may not give two nickels about the technologies in Pantech’s next handset, but the firm’s got a finger on the industry’s pulse. So when an unnamed executive says “phones to be rolled out in the first half of next year” won’t use AMOLED, that hints at when the shortage for US-bound devices might also let up. In case you’re curious, 2H 2011 is when Samsung’s next AMOLED facility is slated to open, though by that point AU Optronics and TPO Display should be shipping the screens as well.
That little gadget up there isn’t a cellphone, although it certainly shares some design points with the old G1 Googlephone. It is actually a MiFi-like cellular hotspot, a little battery-powered box which shares a 3G data connection over Wi-Fi.
Like the MiFi, the Huawei E583C will support up to five devices over Wi-Fi, plus one more over USB, and it has a microSD-card slot for storing and streaming data. The E583C is functionally very similar to Huawei’s UK-only MiFi E585, with an OLED display to show you the router’s status: which network you’re on, the router’s signal strength and battery level. Lest you think that this is a mere gimmick, I’d point out that one of the biggest annoyances with the original MiFi is the lack of visual feedback, especially on battery status.
The price, when it launches in Hong Kong this month, will be HK$1,380, or $178. And before you go, here’s a fun snippet from the press release: “gadget lovers can now experience the excitement of on-the-go wireless internet.” Excitement!
Smartphone maker HTC is switching back to older LCD technology for some of its smartphones because of a shortage of active-matrix OLED displays.
The new crop of HTC phones coming this summer will include a technology called SLCD, or Super LCD, instead of the newer organic light-emitting diode (OLED) displays used in several current-model smartphones, including the HTC Desire and the Google-designed, HTC-built Nexus One.
HTC says SLCD will give consumers a visual experience comparable to HTC’s current 3.7-inch OLED displays. SLCDs will also offer better battery performance, contrast and more-natural balanced color than AMOLED (Active-Matrix Organic Light-Emitting Diode) displays, says the company.
“HTC is experiencing high demand for many of our phones, specifically our phones with 3.7-inch displays,” Peter Chou, CEO of HTC said in a press release. “The new SLCD display technology enables us to ramp up our production capabilities quickly to meet the high demand.”
But just what exactly is Super LCD technology? Two analysts Wired.com spoke with say it may just be a marketing jargon for a variant of the traditional thin-film transistor liquid-crystal display (TFT-LCD) that powers almost all mobile displays currently on the market.
“There’s Super AMOLED, Super IPS and now Super LCD,” says Raymond Soneira, president of research and consulting firm DisplayMate Technologies. “Its like eggs in a supermarket: You can’t buy a small egg anymore. They all start at medium.”
When Google launched its Nexus One phone, the device’s AMOLED screen made a splash because of its vivid colors. Unlike LCDs, AMOLED screens are not backlit, which means they were expected to consume less power than traditional LCDs.
The screens are also more expensive, and their supply is limited, says Jennifer Colegrove, director at DisplaySearch.
“AMOLED is about 20 to 50 percent more expensive than LCD,” she says, “and currently only three companies — Samsung, LG and CMEL — supply it.”
Meanwhile, Samsung has developed the Super-AMOLED display to reduce some of these flaws, make the OLED screens thinner and improve on their visibility in direct sunlight. But Super-AMOLED displays are proving to be an even scarcer component for handset makers.
HTC says the SLCD technology it is using as an substitute can meet its demand without significantly sacrificing quality. SLCD is an improvement over most other LCD panels, because it provides approximately five times better power management and offers wider viewing angles, says HTC. But those claims have yet to be tested.
Details about the SLCD technology itself are scarce and further muddled by a joint venture that Samsung and Sony set up a few years ago that has the same name. In 2004, the two companies set up a joint manufacturing venture for LCD screens and called it S-LCD. The manufacturing facility initially produced LCD screens for TVs but later began focusing extensively on mobile devices. Until now, SLCD was used to refer to the name of the Samsung-Sony manufacturing plant, rather than a specific technology, says Soneira.
But if you are itching to see the differences among all the display technologies for yourself, Mobile Tech World has linked to a video comparison of Sony SLCD vs. AMOLED and Super AMOLED.
In the video, an HTC Desire phone sporting the new SLCD panel is pitted against a Nexus One with the AMOLED display, a Motorola Droid with IPS (in-plane switching, a kind of LCD technology used by many TVs as well as Apple’s iPad), and a Samsung Wave with a Super-AMOLED display.
“I thought all the displays were really good, they all had decent color and respectable viewing angles,” says a user who did the comparison on Howard-Forums.
“The super AMOLED was noticeably less reflective than the others and was blacker with the best viewing angles. Super LCD had a superior horizontal viewing angle compared to a regular AMOLED display. The AMOLED had slightly better blacks and slightly better vertical viewing angles. Both Super LCD and AMOLED were very reflective.”
These five Nexus One smartphones may seem to have defects, but there’s actually nothing wrong with their AMOLED screens — the funky colors are an attempt to improve battery life by turning off unnecessary sub-pixel LEDs. Hooking up his handset to an industrial power meter, Android engineer Jeff Sharkey discovered a blood-red screen drew 42 percent less current than full color — the least of any combination by far — purportedly doubling the effective battery life of the phone. While you’re probably not going to be able to test the requisite software patch for yourself unless you’re mildly familiar with Google code, you’ll find a video of the crimson wonder after the break to fuel your dreams of a eyestrain-free astronomy cheat sheet… and Android bullfighting, of course.
We’ve always wondered whether Microsoft’s multitouch table would actually ever arrive, dreaming of Minority Report hijinx all the while, but after seeing what the company’s Applied Sciences Group is currently cooking up — a touchless telepresence display — we’d rather drop that antiquated pinch-to-zoom stuff in favor of what might be Surface’s next generation. Starting with one of Samsung’s prototypetransparentOLED panels, Microsoft dropped a sub-two-inch camera behind the glass, creating a 3D gesture control interface that tracks your every move by literally seeing through the display. Combined with that proprietary wedge-shaped lens we saw earlier this month and some good ol’ Johnny Chung Lee headtracking by the man himself, we’re looking at one hell of a screen. Don’t you dare read another word without seeing the prototype in a trifecta of videos after the break.
AMOLED displays in phones haven’t necessarily lived up to their promise; they’d been billed as the be-all, end-all answer for clarity, vibrance, and low power consumption, but in reality, the latest and greatest LCDs look just as good, offer similar viewing angles, have little to no impact on battery life, and fare far better in direct sunlight. We’ve been able to confirm this evening that HTC will be adding an additional supplier of displays later this year — Sony — which will be delivering its Super TFT LCD tech as a mobile exclusive (initially, at least) to key HTC handsets, some of which are already in the marketplace.
Specifically, Samsung’s had a devil of a time keeping up with deliveries of its 3.7-inch WVGA AMOLED display, which means that the Desire, Droid Incredible, and Nexus One could all theoretically be impacted — but because this is a problem of the demand for displays outstripping supply (or at least the supply that Samsung is letting HTC buy), at least some of the affected phones will likely be offered both in AMOLED and SLCD varieties. How those products will be differentiated in the market is unclear, but it may not matter much — we’re told that the displays are virtually indistinguishable. We’re working to get our hands on an SLCD phone just as soon as we can, and when we do, we’ll put our eyeballs on the case.
Ah, here we go, Samsung’s other cellphone with an integrated projector just got an official launch date. The Galaxy Beam (codename: Halo) with its 3.7-inch Super AMOLED display is now slated to hit Singapore in July. That means that the European and broader launch across Asia should be just around the corner if Samsung’s claims from Feburary hold true. At launch, the world’s first Android phone with a built-in DLP pico projector will be served version 2.1 of Google’s confectionary delight. Specwise, we’re talking 7.2Mbps HSPA data on 900/1900/2100MHz and quad-band GSM/EDGE, Bluetooth 3.0, 802.11n WiFi, an 8 megapixel autofocus camera with flash (front-facing VGA) and HD video recording, A-GPS, FM Radio, and an 1,800mAH battery. Memory is confusingly listed as “4Gb + 2Gb + 1Gb + 16Gb MoviNAND” made worse by no mention of microSD though it was definitely there when we went hands-on with Beam at Mobile World Congress. Specs after the break.
Strap yourselves in, pilgrims. Nokia’s next great handset has resurfaced in London today, and this time we were even allowed to turn it on. There’s pretty much no way you could be unaware of the N8 by now — Nokia’s done the viral video thing, the teaser demo thing, the feature walkthrough thing, we’ve covered it to near-exhaustion. But we’ve never seen it, you know, doing stuff. You can now consider that omission corrected, as we’ve finally powered up the 3.5-inch OLED screen, entered the overhauled Symbian^3 wonderland, and come back to tell the tale. In-depth impressions and video after the break.
