Nintendo 3DS handheld to offer switchable 2D mode, thankfully
It was pretty much implied when "backward compatibility" was listed as a feature of Nintendo's new 3DS handheld back in March. But it's good to hear that 3D gameplay can be easily switched off, direct from Nintendo president Satoru Iwata, when headaches or nausea set in during marathon sessions. This should also ease concerns from parents over any adverse effects that long term exposure to parallax barrier gameplay could have on their children's developing eyes. Besides, a 2D mode is desirable in that we expect it to offer a brighter image (especially when viewing off-center), better text reading experience, and a wider angle of view for sharing the display. Now, we know what you're wondering: what about that new 3.4-inch glasses-less 3D touchscreen display from Sharp, is it 2D switchable? Yup, lending more credibility that we'll see it on the 3DS when the handheld gaming console is fully revealed at E3 next month.
Toshiba Mobile Display touts 21-inch glasses-free 3D HDTV, raises a few eyebrows
While we were fretting about what special tech Nintendo's 3DS would use to generate autostereoscopic imagery on its comparatively puny screen, Toshiba Mobile Display (and others) have been working on bringing that same headgear-free 3D to TV-sized panels. Employing a "multi-parallax" technique, the latest from the Toshiba spinoff firm promises "significant reduction in eye fatigue" as well as approximately a 30 degree horizontal viewing angle. The latter might be peanuts compared to a quality 2D display, but let's not begrudge being offered at least some positional flexibility. Other specs include a 1280 x 800 effective resolution and 480 nits of brightness, which are notable achievements when you consider that the 9-parallax implementation requires the generation of 9 separate images and therefore could be achieved with only an "ultra-high definition LCD module." We've sadly no info about this panel's potential for retail availability, but judging by the bezel-free picture we've been given, that might be a good way off from now.
NewSight's 70-inch 3DTV keeps the glasses away with its parallax barrier tech
Last week's Finetech Japan 2010 expo allowed display manufacturers to show and tell each other about their latest innovations and advancements. One of the unquestioned highlights was NewSight's implementation of parallax barrier technology on displays up to 70 inches in size. The company is claiming its demo unit as the world's largest glasses-free 3D screen, but regrettably deprives us of any further details. All we're told is that the parallax barrier is "affixed to commercial-grade" LCDs, which suggests to us that perhaps the technique and hardware could be applied atop your favorite brand's existent 2D models. Of course, that'd only matter if these displays deliver a manifestly better picture and experience than what we have now, but it's looking like we'll have to wait a little bit longer to find out.
DXG's 3D View sacrifices HD, but makes 3D video recording pocketable
It's not a trade that we'd ever willingly make -- dropping to standard definition for the sake of some 3D shenanigans, but DXG is offering you the choice anyway. The budget cam maker has just announced its 3D View stereoscopic shooter, which interestingly comes with a separate 7-inch LCD display (800 x 480 resolution) for playing back your recorded footage without requiring glasses -- thanks to some parallax barrier magic. We might be tempted to spend the $400 this package costs just to get a preview of what the Nintendo 3DS -- based on the same spectacle-free technique -- might look like, but retail availability isn't expected until June, which is just that tiny bit too far out for our limited attention span.
Hitachi 3.1-inch 3D IPS display is another Nintendo 3DS contender
Step aside Sharp, Hitachi has a parallax barrier 3D display all its own that likewise doesn't require special glasses to view. While not as bright (400nits vs. 500nits) or big as Sharp's 3.4-incher, Hitachi's contribution brings a 3.1-inch IPS panel to mobile 3D devices pushing the same 480 x 854 pixels and 1,000:1 reported contrast. While the image above won't make much sense outside of Japan, here's the gist: a series of vertical slits in the IPS LCD directs light to the right and left eyes to give the 3D effect -- no special glasses required. Remember, both Hitachi and Sharp have a long, and sometimes dubious, relationship with Nintendo so don't be surprised to see either (or both) announced as partners when Ninty unveils its 3DS handheld console at E3 in June.
Sharp's 3D tablet panel doesn't require glasses, RGBY 3D TVs launching this summer do
Don't think Sharp's going to sit by and let Panasonic, Samsung, and Sony have all the 3D TV fun. The Japanese company, and fourth-largest LCD TV maker, plans to begin selling its own 3D TVs in Japan this summer before launching in the US, Chinese, and European markets sometime later in the year. To prove it, Sharp ponied up some sample RGBY ("Y" for yellow) 3D LCD panels it claims to be the "industries brightest" in sizes up to 60-inches. While these biggie panels all require active 3D shutter glasses for the extra-dimensional effect, Sharp was also showing off a 10.1-inch 3D display prototype for netbooks or tablets that -- like its 3.4-inch parallax barrier display announced last week and suspected to be headed to Ninty town -- doesn't require glasses at all and can be produced with or without a touchscreen. No word on when that pup might begin mass production, however. 60-inch panel pictured after the break with a real live woman doing the pointing -- amazing.
Nintendo 3DS to feature 3.4-inch Sharp parallax barrier display?
There aren't many mass production options on the market when it comes to glasses-less 3D displays for Nintendo's forthcoming 3DS handheld gaming console. And according to early leaks from Japan, the special Nintendo 3DS display is supposedly built by Hitachi and Sharp using a parallax barrier system. So guess where this new 3.4-inch, 480 x 854 pixel display is likely headed? While Sharp doesn't say for sure, it's a good bet that this parallax barrier 3D LCD will be fronting the user interface on the 3DS. Unlike the 3D displays you'll find in modern 3D HDTVs requiring the viewer to wear active or passive glasses, Sharp's display uses a parallax barrier system to create a sense of depth by using a series of vertical slits in an ordinary LCD to direct light to the right and left eyes. The panel offers a 500nit brightness, 1,000:1 contrast, and is available with or without a touchscreen. A non-touchscreen version of the display goes into mass production before June but there's no specific mention of the touchscreen timeline (but we imagine it won't be far behind). In other words, we could have a Nintendo 3DS on the market before the holidays. Just saying. Guess we'll find out for sure at E3 in June. Update: Akihabara News went eyes-on with the display and came away impressed with the colors and brightness. "Sharp have succeeded to do what Sony and Panasonic did without the need for 3D Glasses," the publication praised. Well, that sounds hopeful.
New glasses-free 3D tech uses per pixel prisms for zero crosstalk, audience flexibility
Try as manufacturers might, attempts at autostereoscopic (glasses-free) TV have been subpar; existing tech typically makes for messy images due to ghosting, only provides a 3D effect if you're standing in one of a very few predetermined spots (usually 8-10 viewing angles, though we've heard of 64), and reduces display resolution -- all because only some pixels can be seen from each spot. With the occasional exception, it's not terribly impressive. Scientists at the National Chiao Tung University in Taiwan are looking to change that. Rather than block light with a parallax barrier, their screen uses a matrix of specially cut prisms to reflect it, reducing ghosting to nil and maintaining display resolution by sending the same image to each viewer. Though there are still a fixed number of viewing zones, the prisms are so tiny that manufacturers can simply add more prisms to each pixel to increase that number -- with 11 prisms per pixel, researchers say such a system could support 100 simultaneous 3D moviegoers. We've no word on whether the tech is affordable or when we'll see it, but we expect it to handily beat cyborg eyeballs to market.
Nintendo 3DS to come with '3D control stick,' vibration, and Sharp's parallax barrier 3D LCD?
You had the hard news for breakfast, so how's about some less official, but still pretty robust, fodder for brunch? Asahi in Japan offers the first word on how the 3DS achieves its 3D-ness by suggesting that the new portable game machine with feature a parallax barrier LCD from Sharp. The tech has apparently already been deployed in a few cellphones over there and is described as "unsuitable" for large-screen TVs. This is corroborated by Nikkei, which suggests that the screens on the new device will be smaller than 4 inches diagonally, placing it closer to the DSi than the 4.2-inch DSi XL / LL. Other news from the latter source include so-called 3D control stick(s), though it's not entirely clear whether this'll be anything massively new or just a pair of analog nubs for us to push around. Either way, Nintendo is said to have secured patents for the new control methodology in Japan late last year. The Nikkei article also mentions improvements in WiFi transfers and battery life, as well as a new vibration function. Now that we've got all that out of the way, can someone please tell us if this thing has Tegra inside or not?
2010 Range Rover gets 12-inch 'dual view' touchscreen
We've seen dual view prototypes for ages now, but you can bank on said technology (dubbed Parallax Barrier) being front and center on Land Rover's forthcoming flagship vehicle. Announced today at the New York Auto Show, the 2010 Range Rover will arrive with a 12-inch touchscreen infotainment system that puts off different images depending on the viewing angle. In order words, the driver can check out the route to grandma's house while the lucky soul riding shotgun peeks a DVD -- in theory, at least. The navigation system is HDD-based and also includes a USB socket and a dedicated iPod port. Land Rover even spruced up the voice activation system, giving motorists the ability to voice their concerns about climate and volume (and get instant results). Check the full snippet just past the break.[Via Engadget Spanish]
World's largest 3D display revealed in 4D spacetime
Ooo, ahhh, you feeling that 3D display on your 2D panel? You should, it's the world's largest 3D LCD panel from VMJ measuring in at 65-inches. The stereoscopic panel developed with support from VisuMotion features a 1920 x 1080 resolution, 6-ms refresh, 120-degree viewing angle, and DVI and RGB inputs. Best of all, no goofy 3D glasses of any type are required thanks to the incorporation of Sharp's Parallax Barrier viewing technology. Priced at ¥3.15 million (about $30k) when it starts advertising CosaNostra Pizza around Mr. Lee's Greater Hong Kong.[Via Akihabara News and Impress]
Sharp's triple veil-view LCD
What's better than a dual, veil-view LCD? Why a triple veil-view of course! Sharp engineers have managed to control the angle of visibility using the ol' parallax barrier used in 3D displays. The resulting panel is perfect for those times when you need to get some work done on the computer but your toddler is clamoring to watch the latest download of CSI. Or mount the LCD in the car allowing you to navigate GPS maps while the family chills with a film... or freakin' puppies and plants, whatever just as long as they shut the hell up. No idea where or when these might be available, Sharp's apparently just being a little boastful about their accomplishment. Proud you should be Sharp, now come, we've got a cookie for ya.[Via Impress]
