Light-triggered nanoparticles kill drug-resistant bacteria

Posted on by
Many current attempts at killing drug-resistant "superbugs" amount to racing against time, whether it's improving research technology or developing germ-fighting techniques that are less likely to promote resistance. That's not really an effective l...

Tiny microscope lets you see the smallest-ever inkjet prints

No, that's not an up-close look at a monitor. That's the world's tiniest color inkjet image made large, and you may not need it blown up to see it in the future -- if you're willing to lay down some cash. In a hybrid of scientific discovery and pub...

Tetrapod quantum dot LEDs could lead to cheaper, better HDTVs soon

DNP QUANTUM DOTS IN YO TV

Until Sony started shipping its Triluminos HDTVs, the future of quantum dot (QD) technology in real-world products was mostly theoretical. Now, a company called Quantum Materials has started shipping its "Tetrapod Quantum Dots" material to an unnamed Asian electronics manufacturer, hinting at the possibility of other QD-enhanced products on the market. The company didn't mention any particular devices, but this tech has the potential to create displays that are brighter, more energy-efficient and have greater contrast than the competition.

This technology allows companies to create LED-backlit LCDs using a single material as opposed to several on traditional ones -- this supposedly keeps costs low, although the aforementioned Sony HDTVs were anything but cheap. Quantum Materials CEO Stephen Squires specifically claims his company's tetrapod technology works with fewer dots overall and better manufacturing tech to hit the lowest cost possible. Samsung and LG have shown off quantum dot tech in years past -- we'll eventually find out if either one is the anonymous manufacturer in line to mass produce it.

Google patent would track objects within your gaze

Google patent would track whatever falls within your gaze

Google already has a patent that would let Glass and other eyewear identify what's in front of you. However, it just received a new patent for a method that could follow your exact gaze. The proposed system would include both forward-facing and eye-tracking cameras, correlating both to determine what's grabbing your attention. It could gauge emotional responses to objects by watching for pupil dilation, and it could be used to charge advertisers based on how long wearers stare at a given ad. Google may also have an eyepiece upgrade to go along with its gaze detection, we'd note -- the company just received a patent for a quantum dot-based eye display. There's no evidence that Google will use either of these new inventions anytime soon, but we wouldn't be surprised if they represent what Glass could look like a few generations from now.

Sony’s 2013 HDTVs start shipping, quantum dots are on the way

Posted on by

We got a peek at Sony's 2013 HDTV lineup during CES in January, and now the company has announced they're starting to roll out and confirmed official pricing. The new sets add features like NFC, MHL and Miracast support to certain models, while the top of the line W900A is its first to use Quantum Dot technology in combination with edge LED lighting. Sony's brought back its old Triluminos brand name for the technology, which it claims provides a wider color gamut while keeping prices quite a bit lower than its last TVs to rock the tag, the now-retired XBR8 series.

There's no word on the XBR series, but in the lower W- and R- lines the KDL-W900A is the only one with Triluminos. It also brings an extra long internal speaker duct for improved sound and standard NFC remote, and the 55-inch model will carry an MSRP of $3,299. The step down W802A version keeps MHL standard, has the NFC remote as an option and comes in 55- and 47-inch versions that start at $1,799. The 32-inch W650A will ship for $799. The R-Series dodges some of the higher end features, but some still include 3D, WiFi, RVU and the Sony Entertainment Network suite of apps including Netflix, Hulu Plus and more. The R550A has all that and is available in 70-, 60- and 50-inch versions that start at $1,399.

Quantum dots help return ‘Triluminos’ RGB LED lighting to Sony HDTVs

Quantum dots power the return of 'Triluminos' RGB LED lighting to Sony's 2013 HDTVs

While 4K TVs are excellent, for the next couple of years most of us will still be selecting a 1080p model when we're out shopping, and now we've got a little more detail about some of the new ones Sony announced last week. After letting its "Triluminos" RGB LED lighting technology fall by the wayside after 2009 because of its high cost, Sony has brought the brand back in this year's HDTVs. Noted in the press release and highlighted today in the MIT Technology Review, this iteration uses QD Vision's quantum dot technology to enhance the red/green/blue LED backlighting the series is known for. According to the CTO of QD Vision, the TVs start with a blue backlight -- instead of the standard white LED -- which stimulates quantum dots that emit "pure green and pure red." Sony was very proud of its Triluminos tech at the show and our experience at demonstrations seemed to validate the quality of the approach. While we've been hearing about quantum dots for years, this is reportedly their first appearance in a mass produced consumer product, once it hits homes we'll be able to tell if the wait was truly worth it.

3M and Nanosys team-up to roll out quantum dot-enhanced LCDs

Posted on by

Nanosys' eye-popping QDEF (Quantum Dot Enhancement Film) might be inching closer to a display near you. A new partnership with 3M aims to get the color-loving tech commercialized and into mainstream products. The film uses quantum dots to create an LCD with a wider color gamut -- apparently translating to up to 50 percent more color. The quantum dots are packed onto this film in their trillions (yes, trillions) which is then fitted within the backlight. As the new layer would replace the existing one within LCDs, Nanosys' solution aims to avoid the need for new equipment or processes. However, we're still waiting for high-color QDEF to become that "ecosystem changer" we were promised.
