Move Over Plasma TVs: Nano-Screens Are Coming
By John Brandon May 23, 2005
Motorola revealed its first working nano-emissive display (NED) prototype on Monday at the Society for Information Display (SID) conference in Boston. The company hopes its five-inch diagonal proto-television will attract licensees not yet convinced that Liquid Crystal Display (LCD) and plasma screens are the future of high-definition entertainment.
The wafer-thin display -- it's just one-eighth of an inch thick -- is actually just one section of a theoretical 42-inch television, which could be mounted on a wall and play DVD movies that look just as bright and clear as they would on LCDs. If companies such as Panasonic and Sony choose NED, they could start manufacturing high-definition sets as early as 2007 -- and at the highly competitive price of under $1000.
Motorola has outpaced other carbon nanotube technology innovators, such as Futaba and Samsung, with the first working prototype at a U.S. trade show. (Futaba, a Japanese company, has shown NED prototypes in Japan.) At the conference in Boston, more companies are getting their first look at this promising competitor to LCD and plasma screens that Motorola first announced in June 2003.
It's an opportune time for Motorola's announcement, too, since manufacturers are beginning to explore cheaper alternatives to LCD and plasma screens. As more high-definition DVD formats, television broadcasts, and next-generation video games attract consumers, manufacturers are looking for ways to reduce the production costs of HD screens and make them more affordable for consumers.
Today, the cheapest HD sets cost more than $1000. According to market research firm DisplaySearch, though, an 40-inch NED display could retail for $800 or less.
"It's a much simpler manufacturer process than [cathode ray tube] or LCD," says DisplaySearch vice president Barry Young. "The equipment costs are lower and the material costs are less. LCD requires a very complex manufacturing process, and CRT displays are even more costly to produce."
Even with the high price, though, HDTV sales have increased 43 percent since last year, according to Consumer Electronics Association (CEA), so the market is ripe. And any price drop would likely spur HDTV sales to even greater heights.
Instead of using either one cathode ray tube (CRT) or millions of tiny LED lights to project a video image, NED uses millions of accelerated electrons charged by just 5 to 10 volts of electricity, compared with 5,000 volts for large-screen, high-def LCDs. The electrons shoot toward a phosphor plate, creating the moving image. This technique requires less voltage than a CRT, so the displays won't consume as much power. And, unlike LCD, a nano-emissive display, which uses carbon nanotube technology, will be easily viewable from all angles.
Motorola's NED technology isn't a slam dunk, though, since other companies are also racing to create cheap HD alternatives. What's more, unlike NED and other carbon nanotube-based technologies, some are trying to adapt the more-stable cathode ray tubes to perform better in the digital age. For example, another emissive technology competitor, supported by Sharp and Canon, is known as surface-conduction electron-emitter (SED). It uses a more stable but less efficient method to achieve a similar look to Motorola's NED. The SED uses one cathode ray tube to shoot electrons toward a phosphor plate, as opposed to using more unpredictable nanotubes.
Using carbon nanotubes has several challenges, according to Dr. Yoke Khin Yap, assistant professor of material physics and laser physics at Michigan Tech University. One is growing them in a uniform and consistent fashion, another is sealing the glass display to prevent impurities from corrupting the image quality, and a third is using reliable phosphor coatings.
"Manufacturers would need to maintain a high level of quality in order to keep production costs low," Yap says.
That challenge hasn't stopped Canon and Toshiba, who are jointly developing yet another related technology, an organic light-emitting diode (OLED), which is a film-based carbon technique that has so far been used only in handheld prototypes in the United States. Samsung may be the first manufacturer to release an OLED high-def television display, and recently revealed a full-size prototype in Japan. Still, OLED costs are expected to fall more in line with high-end plasma displays, which leaves the NED technology as potentially the cheapest and best alternative to CRT and LCD screens..
Another critical benefit of NED over other display technologies is no limit to the display size, says Don Bartell, a product director at Motorola. This means the technology could be used by ad agencies erecting monolithic 100-inch roadside billboards and consumers wanting a 42-inch home entertainment centerpiece.
According to Motorola, CRT displays will never extend beyond 36-inch screens and the manufacturing costs for large-screen LCDs will likely remain high for several years.
Of course, until consumers and manufacturers see a nano-emissive display running the latest Hollywood blockbuster or are able to surf the Web on a 60-inch prototype, the carbon nanotube alternative will remain an attractive experiment.
Goliaths Face a Nano Challenger
By Carl Wherrett (TMF Breaker Carl) and John Yelovich (TMF Breaker John)
May 23, 2005
Motorola (NYSE: MOT) and Samsung Electronics are thinking small -- really small -- when it comes to displays. As a result, these Goliaths could face a litigious David in the near future.
Motorola and Samsung recently unveiled flat-panel displays that, because of their reliance on nanotechnology, surpass conventional screens. Carbon nanotubes, the revolutionary substance responsible for a number of nano-breakthroughs in the past decade, figure in both.
Motorola uses nano emissive display (NED) technology -- whereby carbon nanotubes are grown directly on glass -- in its 5-inch-screen prototype. Samsung demonstrated a 40-inch organic light-emitting diode (OLED) display.
Because nanotubes are what's used to emit light in these displays, Motorola and Samsung are likely to encounter turmoil. A micro-cap company, Nano-Proprietary (OTC BB: NNPP), claims the basic patent for several emissive display technologies, including those using carbon nanotubes.
Basic patents differ from design patents and process patents because they claim all rights over a concept regardless of how it's designed or which process is involved. For example, a basic patent covers the intermittent window wipers on a car. Although there are multiple variations on this technology, makers of every type pay a royalty to the owner of the patent, who first conceived of the concept.
Having basic patent rights over nano-displays gives Nano-Proprietary a powerful advantage in what's potentially a multi-billion-dollar market. There's a good chance screens of the type Motorola and Samsung are talking about will take off because carbon nanotubes lead to thinner and more power-efficient screens.
Samsung may start making nano-displays in 2006. Motorola was a pioneer in the television business, but it stopped making displays years ago. As a result, it plans to license its NED technology to third parties. Motorola has been coy about a time frame.
Nano-Proprietary has a tiny market cap of around $234 million. Its business model is built entirely around a portfolio of 240 issued or pending patents. The company is already defending its patent turf, having recently sued Canon (NYSE: CAJ) over yet another display technology, surface-conduction electron-emitter displays (SEDs).
The dispute relates to the fine print of their agreement, which Canon has allegedly infringed by sublicensing patents to its joint venture with Toshiba. That venture plans to invest $1.7 billion in a new production plant for SEDs, providing a huge incentive for Nano-Proprietary to play hardball.
The courts may ultimately decide whether Nano-Proprietary's management is right to be bullish about the future. The company expects to break even by the end of this year and sees profits in 2006 thanks to SED royalties.
Companies beyond Canon will have to decide whether to license Nano-Proprietary's patents or go to court. Investors in Nano-Proprietary should be increasingly excited about its prospects, but we'll wait for the courts to weigh in before we consider the company a prospective Rule Breaker. We risk missing a surge in Nano-Proprietary shares by waiting, but we can hop on board later based on commercial reality.
"On a back plate, only 3 mm behind each sub-pixel, we place a small structure that contains about one thousand CNTs arranged such that a properly applied voltage excites each CNT to bombard the colour phosphors with electrons," explained the spokesperson.
With a thickness of just 3.3 millimeters, the prototype is a 5-inch diagonal section of a 42-inch 1280x720 high-definition television and has a refresh rate of 60 Hz.
Motorola estimates that a 42-inch NED running typical video would consume 75 W. In comparison, the firm says a similar LCD would consume around 180 W because it requires a 60 W backlight and matrix switching.
Motorola Labs Debuts First Ever Nano Emissive Flat Screen Display Prototype
Building Upon Carbon Nanotube Technology, Motorola Prepares to Revolutionize the Flat Panel Display Industry
SCHAUMBURG, Ill. 09 May 2005 Motorola Labs, the applied research arm of Motorola, Inc., (NYSE: MOT), today unveiled a working 5-inch color video display prototype based on proprietary Carbon Nanotube (CNT) technology a breakthrough technique that could create large, flat panel displays with superior quality, longer lifetimes and lower costs than current offerings. Optimized for a large screen High Definition Television (HDTV) that is less than 1-inch thick, this first-of-its kind NED 5-inch prototype harnesses the power of CNTs to fundamentally change the design and fabrication of flat panel displays.
The development of such a flat panel display is possible due to Motorola Labs Nano Emissive Display (NED) technology, a scalable method of growing CNTs directly on glass to enable an energy efficient design that excels at emitting electrons. Through this cost-effective process and design, Motorola showcases the potential to create longer-lasting NED flat panel displays with high brightness, excellent uniformity and color purity.
With over 15 years experience and 160 patents in CNT and flat panel displays, we have developed a technology that could enable the next generation of large size flat panel displays to deliver an extraordinary visual experience at a fraction of current prices, said Jim OConnor, vice president, Motorola technology incubation and commercialization. We now look forward to aligning with display manufacturers and enabling them to further this technology and develop commercially available solutions.
Motorolas NED technology is demonstrating full color video with good response time, said Barry Young, VP and CFO of DisplaySearch, a leading flat panel display market research and consulting company. And according to a detailed cost model analysis conducted by our firm, we estimate the manufactured cost for a 40-inch NED panel could be under $400.
Motorolas proprietary CNT growth process provides excellent precision in designing and manipulating a material at its molecular level enhancing specific characteristics and, in the case of flat panel displays, producing high-definition images. The electron emission performance demonstrated by the Motorola technology exceeds that achieved to date with the application of the CNT to the cathode via an organic paste, the process used by other companies.
Motorola has proven its NED technology to be fully video capable, said Kimberly Allen, Director Display Technology and Strategy for analyst firm iSuppli. CNT direct growth on glass appears to have advantages over CNT paste/printing approaches and has potential for larger and more sophisticated displays.

swear these things are like the new plastic.
It sounds like the greatest material ever made.
Materials: Carbon Nanotubes
Silicon's likely successor, and much more
It's the Clark Kent of microelectronics. In the early 1990s, scientists at the NEC Fundamental Research Laboratory in Tsukuba, Japan, discovered a tiny graphitelike structure with the most beguiling dual identity. Sometimes it's a metal, and sometimes it's a semiconductor. It can serve as a wire, transporting current from one place to another, and it can also serve as a transistor, using changes in current to store information.
This microscopic structure, known as a carbon nanotube, could be the secret to extending Moore's Lawwhich predicts that the number of transistors on the fastest CPUs will double every 18 monthsbeyond the limits of today's silicon microprocessors (quite a feat in itself). "This is our best hope for the next generation of electronics," says Jie Liu, a Duke University chemist at the forefront of carbon nanotube research. It is also the basic building block for all sorts of future products, from flat-panel displays and long-lasting batteries to fishing poles and satellite cables (pound for pound, nanotubes are 10 to 100 times as strong as steel).
AMD, IBM, and Intel will continue to improve silicon-based CPUs for at least another decade (see "Extreme Ultraviolet Lithography"). But when they are unable to shrink silicon transistors any further, they may abandon silicon altogether and move on to completely new materials.
Only 1/100,000 the thickness of a human hair yet exceedingly durable, a carbon nanotube is akin to graphitea sheet of carbon atoms arranged in a tight honeycomb pattern. Your pencil tip consists of stack after stack of such microscopic sheets. Carbon nanotubes are formed when the sheets of atoms are rolled into cylinders. "They look a lot like hollow cigars," says IBM researcher Joerg Appenzeller.
When carbon atoms assume a certain arrangement along the length of a tube, the nanotube behaves like a semiconductor. In a different arrangement, it becomes a metal. Semiconductors conduct current at certain voltages but not others. They are used to build transistors, in which processors store information. When one voltage is applied, current flows freely through the nanotube, and the transistor turns on. When a different voltage is applied, the current stops, and the transistor turns off. Metals, which conduct at any voltage, are used to build the wires that connect transistors.
In theory, you could build an entire microprocessor from carbon nanotubes. Its parts would be far smallerand thus far fasterthan the copper wires and silicon transistors used today.
Nanotubes are the by-products of various chemical reactions. Scientists can easily grow them on a substrate by reproducing these reactions, but they're struggling to arrange nanotubes in complex circuit patterns.
Researchers are still seeking answers. "How do you control their physical properties? How do you grow them in the right place? How do you connect them?" asks Bob Gassar, director of components research at Intel. "Those are not trivial problems, and they may never be solved."
Carbon nanotubes show promise for an extraordinary variety of products. IBM recently demonstrated a carbon nanotube that produces infrared light. Motorola and Samsung are working on carbon nanotubes for flat-panel displays. Nantero is developing nanotube-based memory. And researchers at the University of North Carolina have shown carbon nanotube batteries to hold twice as much energy as conventional batteries.
Intel has just launched a research program on carbon nanotubes, which means the company believes there's a good chance they'll be used in production-level processors within the next ten years. A dual identity has its advantages.
morbidaza said:I swear these things are like the new plastic.
Kleegamefan said:Another intresting CNT fact; they can be either a conductor or an insulator depending on how the CNTs are configured on a substrate.....meaning you can create entire microchips out of CNTs, in theory...
You can also create RAM out of CNTs...there is a company called Nantero that is developing NRAM....since it uses carbon nanotubes, NRAM can be 50 times smaller than traditonal memory and can have switching speeds up to 3000 times faster....
Furthermore, NRAM is non-volitile.....it can contain data without electical power so future NRAM-based PCs could be powered on instantly....like a light switch...
Very instresting stuff:

StoOgE said:did they just say the TV would be 1/8th of an inch? Thats fucking nuts.
cubicle47b said:Seriously, what's up with this stuff? It sounds like the greatest material ever made.
Crazymoogle said:The retail product is not likely to be nearly that thin - there is also the glass/plastic shield, plastic casing and any other electronic components needed to supply power and the video signal - but it seems likely to match LCD panels in size.
itschris said:Do you know much about OLEDs, klee? I've only read a few things about them, but they seem pretty cool too.
HokieJoe said:You mean flat panel right? Not more than say 5" thick?
Crazymoogle said:Yeah. Basically, it's small enough to compete with any LCD product on the market. (Most of the weight in an LCD panel is just the glass, which is why 30+" panels still have a lot of heft to them. If the CNT display itself turns out to be significantly more rugged (hard to say in an emitter configuration), there is a chance of a thinner cover material, which in turn means a comparatively thinner display to LCD.
HokieJoe said:IF this tech goes big time, I would imagine that this would put a serious hurt on the flat panel guys. I know they've improved their yields, but from what I've read they scrap a lot of panels because they're so hard to manufacture.
Kleegamefan said:Even at $800, TV companies can make a heady profit if the $400 manufacturing costs are also true...
I hope so. I don't have $800 for a TV, but I also don't need something that's 50". A cheaper 30" model would be perfect for me.sp0rsk said:are they gonna make like 25-30 inch ones for 300 dollars
Dragona Akehi said:So, hopefully someone is going to make a nice small model (26" widescreen or less) and it'll have all of the high points of CRT? And be able to do 720p (maybe even 1080p), and it'll be cheaper than what's already out on the market?
Sounds too good to be true, if you ask me.![]()
Seriously. I'm trying not to get too excited, because it's as if Motorola has plucked ideas from my dreams and is implementing them in actual television sets. It's just hard to believe that could be coming within 1-2 years.Dragona Akehi said:So, hopefully someone is going to make a nice small model (26" widescreen or less) and it'll have all of the high points of CRT?
