Quantum dots help return 'Triluminos' RGB LED lighting to Sony 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.
LG and QD Vision unite for QLEDs: the quantum dot displays of our power-efficient future
Seems like LG really has a thing for those quantum dot LEDs. After hooking up with Nanosys earlier this year, the Korean giant is now stretching out another of its tentacles -- LG Display, to be specific -- for a partnership with a competing QLED designer in QD Vision. What's being promised by this joint venture falls right in line with your generic pipe dream -- better color accuracy than OLEDs, up to twice the power efficiency at a given color purity, and a cheap and straightforward manufacturing process. In fact, because QLEDs do not require the same glass substrate as most current display technologies, they offer unmatched flexibility (olé!) in terms of how and where they may be used. The only downer, and you had to know there would be one, is that QD Vision describes its tech as still in the "development stage," but hey, at least we have another cool acronym to add to our library.
Quantum dots make for more pleasing LED lamps
Many who grew up beneath a warm, inefficient incandescent or halogen glow are having a hard time coming to grips with the stale, stiff, efficient illumination provided by CFL or LED bulbs. Two companies, Nexxus Lighting and QD Vision, have paired up to change that, with the former providing an 8 watt (75 watt equivalent) LED bulb, and the latter providing a thin film of quantum dots that can precisely control its color. The dots are microscopic particles that filter light into different colors depending on their size, from red to blue as the dots get smaller -- some only 10 atoms in diameter. The first bulbs are due later this year, and while no word on price is given, Nexxus's current LED bulb costs $100 on its own and surely that layer of dots won't come cheap. Also, no word on whether you'll need to use a Handlink to turn the thing on and off.[Via Physorg]
