(PhysOrg.com) -- A British firm's quantum dot technology will be used for flat screen TVs and flexible screens, according to the companys chief executive.
The quantum dots will be in use for ultra thin, light flat screen TVs by the end of next year, and, in another three years, will be used in flexible screens rolled up like paper or used as wall coverings.
The company, Nanoco Group, is reportedly working with Asian electronics companies to bring this technology to market.
The first products we are expecting to come to market using quantum dots will be the next generation of flat-screen televisions, Nanoco chief executive Michael Edelman has stated.
Nanoco describes itself as the world leader in the development and manufacture of cadmium-free quantum dots. While quantum dots technology is not new, the scientists at Nanoco are succeeding in their goals toward mass production. Earlier this year, the company, which was founded in 2001 and is based in Manchester, announced it successfully produced a1kg batch of red cadmium-free quantum dots specified by a major Japanese corporation.
The ability to mass-produce consistently high quality quantum dots, says the company site, enables product designers to envisage their use in consumer products and other applications for the first time, and then bring the products to market.
Quantum dots are nano-materials with a core semiconductor and organic shell structure. This structure can be modified and built on to ensure the quantum dots work in applications that may use different carrier systems. This includes but is not limited to printing ink including ink jet printing, silicone, polycarbonate, polymethyl methacrylate based polymers, alcohols and water.
Nanocos team says it can manipulate the organic surfaces of the quantum dots to work in applications like electroluminescent displays, solid state lighting and biological imaging.

Individual light-emitting quantum dot crystals are 100,000 times smaller than the width of a human hair. Large numbers used together potentially create room-sized screens on wallpapers.
The ability to precisely control the size of a quantum dot enables the manufacturer to determine the wavelength of the emission, which determines the color of light that the eye perceives. During production the dots can be tuned to emit any desired color of light. Dots can even be tuned beyond visible light, into infra-red or the ultra-violet.
Nanoco defines itself as a world leader in the development and manufacture of cadmium-free quantum dots at a time when being cadmium-free presents special advantage. Cadmium is generally used in LEDs in lighting and displays. The European Union has made it exempt, though, from its Restriction of Hazardous Substances (RoHS) directive due to the fact that there isnt yet a practical substitute, according to eWEEK Europe. That exemption is to end in July 2014.
Our research and development department is also constantly engaged in the creation of new quantum dots with additional properties sought by the market, such as our RoHS-compliant heavy metal-free quantum dots, says the company.
This is what I’m talkin’ about!
Imagine the cloaking technology.
Interested in the HDTV ping list?
Please Freepmail me(freepmail works best)if you would like your name added to the HDTV ping list,(approximately 375 freepers are currently on the HDTV ping list).
The pinged subjects can be HDTV technology, satellite, cable, and OTA HD reception (Over The Air with roof top or indoor antennas), Broadcast specials, Sports, Blu Ray/HDDVD, and any and all subjects relating to HDTV.
Note: if you search Freerepublic using the keyword " HDTV ", you will find most of the past HDTV postings.
Oh, hadn’t considered that. I’d love to know how far our spooky types have taken cloaking technology. I’ll bet it’s way beyond where we think it is.
Kewl..now we can use it to line the bottom of birdcages..I can have my parakeet crap LIVE all over Chris Mathews and Al Sharpton every day..
Could the fictional cloaked alien technology in Schwarzenegger's film “Predator” be with us in the next 25 years??
Thats a scary thought.Somebody could be standing in your front yard spying on you a you would never know it.
Or in some coffee beans.
Seriously, if someone had asked me, back when the movie came out, I would've said cloaking technology was hundreds of years in the future if it was possible at all. Now look at us. It appears there are several plausible ways to achieve it even, perhaps, by means of advances in television technology. Unbelievable!
Ooooo.... imagine changing the decor of your house by simply changing the channel of the “wallpaper” . Flippin killer application for interior design. Not to mention for watching NASCAR football or Iron Man.
Imagine the pranks you could pull.
Out of nowhere, an scary image looks like it leaps out to grab you.
About time to give a sample to Iran.
I've never seen it. Must be awesome!
Lolz! Ah! For the love of commas! Ya got me!
I tried infrared emitting quantum dots for labeling biological samples for imaging a few years ago, and was disappointed in their performance. They did not fluoresce as brightly as regular infrared dyes in imaging.
Perhaps they will work better in HDTV applications and the like. I don’t know. But in my experience, they did not live up to the hype.
Sure, till you realize that it's off level by a couple of degrees and have to strip it off and try again. And again. And again. :)
We can throw shoes at it and it wont break? Cool!
I’m thinking holodeck version 1.
