World’s Largest Cinemascope 3D TV?

Size matters, especially for TV makers competing to come up with larger and thinner screens. Stealing the limelight at the China Optoelectronics Display Expo in Shenzhen is AU Optronics (AUO) and its new 71-inch display. The Taiwanese LCD panel maker is calling this mammoth the world’s largest cinemascope 3D TV, featuring an ultra-wide 21:9 aspect ratio. Read more…

MIT: New Approach To Glasses-Free 3D Technology

Researchers at MIT’s Media Lab announced on Wednesday that they have developed a new approach to glasses-free 3D technology.

The team said they could double the battery life of devices like Nintendo’s 3DS portable gaming system without compromising screen brightness or resolution.

The researchers also said that their technique would expand the viewing angle of a 3D screen.

According to Doug Lanman, a postdoc in Associate Professor Ramesh Raskar’s Camera Culture Group at the Media Lab, Nintendo’s 3DS relies on an older technology known as parallax barrier.  This requires two versions of the same image, both of which are sliced into vertical segments and interleaved on a single surface.

The team’s HR3D system uses two layers of liquid-crystal displays.  The top LCD displays a pattern customized to the image beneath it.

This top layer consists of thousands of tiny slits, whose orientations follow the contours of the objects in the image.

The slits are oriented in so many different directions that the 3D illusion is consistent no matter whether the image is upright or rotated 90 degrees.

Lanman said in a statement that if a device like the 3DS used HR3D then its battery life would be longer because the parallax barrier would block less light.

The 3D image would also be consistent no matter the viewing angle.

“The great thing about Ramesh’s group is that they think of things that no one else has thought of and then demonstrate that they can actually be done,” Neil Dodgson, professor of graphics and imaging at the University of Cambridge in England, said in a statement.

“It’s quite a clever idea they’ve got here.”

However, Dodgson said that HR3D is very computationally intensive.

“If you’re saving battery power because you’ve got this extra brightness, but you’re actually using all that battery power to do the computation, then you’re not saving anything,” he says.

Luddites Rejoice! New Glasses Let You Watch 3D Films in 2D

Per Discover:

Eyestrain. Headaches. Nausea. For some people, this is all part of the 3D movie experience. And until now, your choice was to either suffer through 3D; find a cheaper, low-tech theater; or else forgo some new films altogether. But that was before one guy invented 2D Glasses, a pair of specs that converts projected 3D images into 2D (yup, you read that right). It’s touted as a way of preventing eye strain while still enjoying a flick with your 3D-loving friends. Read more…

Gunnar Optiks Phenom 3D

3D glasses typically come in two flavors. If you have an active 3D HDTV, you use expensive and bulky active-shutter glasses that need to be wirelessly synced with the TV to work. If you watch a 3D movie in a theater or on a passive 3D HDTV like the Vizio XVT3D650SV ($3,699.99, 4 stars), you use passive 3D glasses. This type uses filtered lenses instead of LCD shutters to help display the 3D image. Here, the panel does most of the work and the passive glasses are lightweight, cheap, and often disposable. Gunnar Optiks offers a third type of 3D glasses: passive specs built to last. At $99 (list) they’re priced more like active-shutter glasses or brand-name sunglasses, but solid build quality and good looks make them a nice alternative to 3D theater glasses. Unfortunately, since they’re not dark enough to be sunglasses, their only real purpose is 3D movies, so it’s hard to justify dropping $100 on a pair you’re not likely to use very often.

For 3D glasses, the Gunnar Phenom pair is very well-made, it looks and feels as good as Oakley or Ray-Ban shades. The sturdy, all-metal frames have hidden-spring hinges that let your temples spread out comfortably. The nose pads are mounted on thick wire arms screwed, resting just right on the bridge of the nose. In tests, with my oversized skull, the Phenom was remarkably comfortable.

The glasses work with any passive 3D display, including select Vizio and LG HDTVs and theaters that show RealD 3D movies. Whether you want to watch a 3D movie at home or in the theater, the Phenom is a much more comfortable option than the cheap, plastic glasses included with passive 3D HDTVs or those you get at the movie theater. Since the glasses use the exact same filters as any other passive 3D glasses, they don’t enhance or alter the 3D experience in any way (except for the benefits of the lens geometry, as explained below). The 3D you see through the Gunnars is the same 3D you’ll see through the cheap pack-in glasses.

While Gunnar doesn’t recommend the Phenom 3D glasses for use as sunglasses, they’re still good for partly cloudy days. According to Gunnar, the 3D lenses are tinted to about 50 percent, while typical sunglasses are generally tinted to about 80 percent. This means the lenses aren’t quite dark enough for bright days. The 3D lenses are coated with 100 percent UVA and UVB protection, however, so they can still protect your eyes.

Samsung obsoletes its first-gen 3D eyeware with a move to Bluetooth syncing

If you brought a Samsung 3D TV with Active Shutter glasses during 2010, don’t expect them to work with Samsung’s 2011 3D TV range. The compatibility issue was confirmed by Samsung UK’s marketing chief Russell Owens to HCC during this week’s CES.

The reason for the early obsolescence is a move across the board by the brand to embrace Bluetooth sync emitters in all new Samsung 3D screens. ‘There were too many compelling reasons not to shift to Bluetooth,’  Owens told HCC. ‘Our new super-lightweight 3D glasses no longer require users to manually switch them on. They autosense the 3D signal from the TV. You merely put them on and they work.’

Why do I need glasses for my 3d tv?

For the most part, you cannot register a 3D image on a 2D surface such as a TV without optical help.

History

Interestingly, the issue of 3D and glasses isn’t new. 3D is a concept inventors have worked on for almost two centuries. And you can understand why. 3D brings a 2D image to life. You feel as though you’re part of an exciting visual experience.

Back in 1844, for instance, a Scottish inventor, David Brewer, made a stereoscope. This optical device enabled viewers to see specially taken photos in 3D.

11 years later, a very basic stereo camera appeared – the Kinematoscope. The public had to wait until 1922, though, for the first 3D film. This was in black and white. The first film in 3D colour arrived in 1935.

Red and Green

3D films of the 1950s such as House of Wax were a great success. To view them you needed a pair of glasses that had a red and a green lens.

Cinemas often issued these glasses at the door. They usually had cardboard frames with plastic lenses. As you might expect, the standard of 3D was dubious. Images were sometimes distorted and flickery.

Nonetheless, 3D remained popular for a while because it was a novelty. But after a while, it fell into disuse.

Modern Glasses

What 3D really needed was the right technology to give it a boost. This technology has now arrived.

The quality of 3D on the latest TVs is remarkable. Take a look at Panasonic’s Full HD 3D TVs and see for yourself.

But you can’t get away from the simple optical fact that our eyes cannot appreciate 3D TV without glasses. The latest answer to this is liquid crystal shutter technology. When you wear a pair of liquid crystal shutter glasses, you can watch 3D films and broadcasts on a compatible TV.

With a Panasonic 3D TV, for example, the right and left liquid crystal lenses of the glasses close and open in turn. They do this in conjunction with alternating right and left side images on the TV screen.

To achieve this, the glasses link directly to the TV with an infrared transmitter. Such glasses are truly state-of-the-art. And when you try a pair and watch a sports broadcast or a film, you’ll see why reviewers are saying the future of TV is 3D.

If you have a chance, go along to a 3D demonstration at a local TV retailer. See for yourself what the fuss around Full HD 3D TV is all about. And experience the next level of home entertainment.

Plasma TV has taken a leap forward. The latest plasma 3D TVs with liquid crystal shutter glasses open up a new world of entertainment.

3D glasses too nerdy? Tron: Legacy goggles from Oakley put the chic in geek

If you’re still dithering over whether to adopt 3D, is it the geeky glasses putting you off? If so, maybe you’ll sit up and take notice at Oakley’s announcement of special edition passive 3D glasses celebrating the release of TRON: Legacy, the much-anticipated Disney 3D film opening in the UK in December.

Much as we’re excited at the prospect of the movie, a sequel to the innovative 1982 adventure Tron, we feel that we’d get more out of it by wearing Oakley’s cool 3D shades. The catch is that these are passive glasses (meaning they’ll work in the cinema, but not with most 3D TVs, which require active shutter glasses) – also, they cost $150, which kind of puts in perspective the price of a cinema ticket and popcorn.

Gucci To Release Retro-Looking 3-D Glasses in December

You know, when we were telling you that just about everyone’s trying to bank on the whole 3D frenzy these days, we weren’t kidding around, since it would seem that even some of the world’s largest fashion-oriented companies are trying to get a piece of the pie for themselves, the latest being none other than Gucci.

Of course, the company has not gone as far as rolling out some 3D display, but in fact chose to adapt some of its iconic glasses in order to support polarized 3D displays, the Luxist reports.

Before moving to the actual technical features, we’ll have to admire the fact that Gucci embarked on this trend, being, in fact, among the first household names in fashion to accept the fact that 3D is most likely here to stay, and that there’s good money to be made from the viewers’ penchant for replacing the rather ugly-looking theater glasses with some high-quality, stylish ones.

SAMSUNG OFFERS PRESCRIPTION EYEWEAR FOR 3D TV VIEWERS

Samsung Electronics Co., the world’s largest TV supplier by shipments, said Wednesday that it has launched 3D TV eyewear in a bid to induce more consumers to buy its latest flagship features.

Buyers of the South Korean maker’s 3D-equipped TVs can have their 3D spectacles prescribed by eyewear specialists at designated local shops, Samsung said in a statement.

The 3D capability, which gives multidimensional effects to flat-screen images, is touted by TV makers as a new technology that will fuel further demand in the industry. But obstacles, including the dearth of 3D content and the inconvenience of wearing special eyeglasses, were seen as delaying widespread popularity.

Samsung plans to offer two kinds of 3D eyewear for adults and children, it said.

After globally launching its 3D TV in March, Samsung’s sales of 3D TVs reached 1 million as of August. The company said earlier that it aims to sell 2 million sets globally.
