(PhysOrg.com) -- A British firm's quantum dot technology will be used for flat screen TVs and flexible screens, according to the company’s 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.
Nanoco’s 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.
Here come the quantum dot TVs and wallpaper To be sure, flexible displays that can be used as wall coverings have been of interest. 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 isn’t 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.
I’ve always wanted a live view of the sky projected on my ceiling.
how about covering your car with it? then you could dial up whatever exterior you wanted?
Does this mean video gamers will get the whole wall, rather than a regular flat-screen TV?
Well it doesn’t apply to me anyway, I use a small one and sit pretty close. Kicking butt and talking trash is a priority.
Be careful what you wish for, kids love crayons......LOL!
UV and IR bands available. So, it could double as a tanning bed and a space heater.
Bflr
Lots of different applications for this stuff.
Consider Christmas cards with video. They already have the musical and record/playback cards, a really inexpensive electronic paper could be used to great effect.
Likewise, a large screen could be rolled into a tubular shape of whatever size, and simply unrolled for viewing, much like the old movie projector screen.
Wireless internet and other applications could be included in the device allowing for a number of different display options, or simply a wireless and digital ports option allowing hookup to devices.
"Surround TV" is also possible. Imagine your livingroom as the infield at Daytona, or the line of scrimmage at the Superbowl?!
I bought a 32’ Vizio on 12/2. My failed.
I spent some time getting everything hooked up and it all worked. I gradually tweaked the custom settings till it suited. I switched HDMI inputs to the computer and there was the cable box. It was there on all three HDMI inputs.
To make a long story short, I chatted with Vizio on line, did a reset and all was ok.Except, that night it was all HDMI again. I chatted again a week later and learned there was a firmware glitch causing the problem. If you turned off the speakers, the HDMI ports became corrupted and there was a signal from HDMI port 1 distributed to all three.
Vizio is making a firmware change and will put it on the web. The change will be downloaded to a thumb drive and input through the TV USB port.
Strange and for an old guy like me......... complex
The TV is very good once tweaked and the ability to switch inputs to my dedicated computer with a hard drive full of programming is great.
When I was a kid TV’s you could hang on a wall were science fiction fantasy. Now I have a 50” plasma about three inches thick.
I can only imagine how cool these TV’s will be.
Careful, that ash just about hit your foot.
Just put me on a sit-n-spin and play: “you spin me right round”... lol
Put yourself in a 1986 timeframe and ask if it would be possible to carry a high end camera, videocamera, telephone, computer, data storage device, etc., around in your back pocket in 25 years.
Couldn't resist. Glad you took it well. Some people get all fussed up.
