[CEATEC] FE Technologies Demonstrates FED Panel Rendering Video at 240 fps

Satoshi Ookubo, Nikkei Electronics
Field Emission Technologies Inc. (FE Technologies) presented and demonstrated an FED panel capable of video rendering at 240 fps at CEATEC Japan 2007.
The frame rate is as fast as 4 ms per frame, which is "close to the limit that the human can sense and therefore can't cause viewers to feel the blurring of video," according to an attendant at the company's booth. Video at 240 fps is optimal for applications such as videogames, the company said.
The panel was a 19.2-inch model with 1280 x 960 resolution. Its peak luminance is equivalent to that of LCD panels, FE Technologies said. If power consumption when actually rendering video is compared with LCD panels, "FED panels' power is lower and may be as low as around 1/3 that of LCD panels," said the attendant. FE Technologies had announced that it had succeeded in developing a 240 fps FED panel in August 2007, which was on display at this year's CEATEC.
The company also demonstrated 24 fps video, which is frequently used for movie content, using the same FED panel at its booth. FE Technologies stressed that the FED panel supports a range of frame rates from 24 to 240 fps.
FE Technologies is an FED panel development company that Sony Corp. jointly formed with an external technology investment fund, Technology Carve-out Investment Fund (TCI), toward the commercialization of FED panels in December 2006.

First it was CRT. Then we got LCD and PDP and DLP and LCoS. After that, the never-growing OLED (http://gizmodo.com/gadgets/oled/) and the ever-delayed SED (http://gizmodo.com/gadgets/sed/) appeared. Today, it's all about WTF because FED has arrived and Sony wants it to stay.
But you are probably asking yourself: What in the name of all that is sacred, good and wears latex pants is FED? And would it require me to use one of those cool silver anti-radiation jackets? FED stands for Field Emission Display, a technology that is similar to SED but that uses a grid of carbon nanotubes to emit the electrons that excite phosphor dots in order to create the image.
Sony has just presented a new 19.2-inch 1280 × 960 pixel, 400cd/m2 panel demonstrating the technology, with an impressive 20,000:1 contrast. They want to release it in 2009, with models up to 30 inches with Full HDTV support. More details and photos after the jump.

In a way, FED it's like coming full circle to Sony's good old Trinitron, but with less power consumption, and in a super-thin frame. There's also a very wide angle of vision and a total lack of death pixels (apparently, even if 20% of the emitters fail, you won't see any dead pixels).
Looking at the pictures, however, it looks like FED will also have at least one of the issues of old CRT technologies: screen flicker. However, looking at the specs this doesn't seem to be the case: FED supports 24 to 240 frames per second refresh and the artifacts are likely due to the lack of sync between the ambient fluorescent lights and screen frequencies.
There's no word on prices yet, but apparently they are going to be cheaper to make than LCDs because it uses fewer components.

What is FED-Display?


FED means field emission display
A field emission display is a type of flat panel display using field emitting cathodes to bombard phosphor coatings as the light emissive medium.
Field emission displays are very similar to cathode ray tubes, however they are only a few millimeters thick. Instead of a single electron gun, a field emission display (FED) uses a large array of fine metal tips or carbon nanotubes (which are the most efficient electron emitters known), with many positioned behind each phosphor dot, to emit electrons through a process known as field emission. Because of emitter redundancy, FEDs do not display dead pixels like LCDs even if 20% of the emitters fail. Sony is researching FED because it is the flat-panel technology that comes closest to matching the picture of a CRT.
High-Definition Carbon Nanotube TVs:
The new TV screens are a nano version of the field emission displays (FEDs) developed by Motorola and others during the 1990s. Although that technology produced dazzling prototype displays, it cost too much to compete with liquid crystal displays (LCDs). "It didn't make sense to build a factory [for conventional FEDs]. The cost [of LCDs] was halving each year," says Kenneth Dean, who leads development for carbon nanotube displays at Motorola. However, he says, carbon nanotubes have given field emission technology a second wind by yielding cheaper components that can be manufactured more easily.
Like LCDs, FEDs are energy efficient and could provide a flat panel technology that features less power consumption than existing LCD and plasma display technologies. They can also be cheaper to make, as they have fewer total components. As of yet, however, there are no consumer production models available in the United States, although small demo panels have been produced.
A field emission display (FED) is a low power, flat cathode ray tube type display that uses a matrix-addressed cold cathode to produce light from a screen coated with phosphor materials. The principle of the field emission display is similar to that of the traditional cathode ray tube display. Field emission displays, like cathode ray tubes, display a color image by emitting light of a predetermined color through the bombardment of electrons onto a field emitter array (FEA) coated with phosphor. They both emit electrons to hit the fluorescent medium on a substrate in vacuum. Electron emission includes field electron emission, secondary electron emission, and photoelectric emission, as well as thermionic emission. A cold cathode is the cathode that performs electron emission by field electron emission, which occurs due to a tunnel effect when a strong electric field is applied to the vicinity of the surface of a substance to lower the potential barrier on the surface. The cathode ray tube display emits electron beams by a single electron gun and controls the direction of the electron beams by using a polarization plate. Instead, the field emission display is composed of hundreds of thousands of active cold emitters, each of which corresponds to a pixel independently, so no polarization plate is needed. Field emission displays (FEDs) apply a strong electric field from a gate to a field emitter disposed on a cathode layer at regular intervals, thereby emitting electrons from the field emitter, colliding the electrons with a phosphor material of an anode layer, and emitting light. The cold cathode electron source is broadly divided into a field emission electron source and a hot electron type electron source. The former includes a spindt type electron source, a surface conduction type electron source and a carbon nanotube type electron source. The latter includes an MIM (metal-insulator-metal) type electron source stacked with metal-insulator-metal and an MIS (metal-insulator-semiconductor) type electron source stacked with metal-insulator-semiconductor. When displaying an image in the field emission display, a driving method called a line sequential scanning scheme is used standardly. Display in each of the frames is performed for each scan line (horizontally). All the cold cathode electron sources corresponding to the number of data lines on the same scan line are operated at the same time.

Projected Price??

Projected Price??

I have not uncovered any price predictions on it yet. Perhaps they may have more news at the CES show in early January. I am hoping that they might demo it there.

I expect, like OLED, it will probably be very costly at launch time.

If I uncover any more details, I will post them on here.

Has anyone heard any reports about if Sony will demonstrate this FED display at the CES in January?

A company spun off from Sony is developing a line of monitors based on FED (field emission display) technology, which offers faster response times, consumes less power, and produces warmer, more realistic images than is possible with other flat-panel technologies.
Field Emission Technologies plans to ship a line of high-end professional FED video monitors in 2009, said Norihito Nishimoto, a spokesman for the new company. The monitors will be offered in a range of sizes up to 32 inches, he said.
The company showed off several 20-inch FED prototypes at the Ceatec exhibition in Chiba, Japan.
Sony once pinned its hopes for flat-panel televisions on FED technology.
In 2004, Makoto Kogure, then president of Sony’s television group predicted FED televisions were just around the corner.
“Technology-wise, with no business or investment issues, in two years it’s easy [to produce a commercial FED],” said Kogure, who is now Sony’s corporate executive in charge of product quality and safety.
But slow development and advances in other display technologies led Sony to ditch FED technology in favor of LCD and OLED (organic light-emitting display) screens. Sony unveiled the world’s first OLED television this week, an 11-inch model that will go on sale in Japan this December for ¥200,000 (US$1,740.50).
FED technology is similar in some ways to older CRT (cathode ray tube) technology: phosphorous dots are bombarded by streams of electrons that cause the dots to become illuminated. But unlike CRTs, which use electrons beamed from a single source and deflected to cover the entire screen, FED uses an array of emitters directly opposite the color pixels.
In addition to consuming less power and producing better colors than LCDs, FED also supports faster frame rates. At Ceatec, Field Emission Technologies showed off an FED display running at a rate of 240 frames per second — twice the number that can be handled by the latest models in Sony’s Bravia line of LCD televisions.
In December 2006, Sony spun off its FED research group as Field Emission Technologies, and sold a stake to TechGate Investment Inc.’s Technology Carve-Out Fund. The fund now holds 64.5 percent of the company.
Field Emission Technologies claims FED screens can be produced more cheaply than LCDs because they do not require a backlight. In addition, FED screens can use the same driver as an LCD.


The only problem is that Field Emission Technologies does not have a production line for its displays, and startup costs for a line will initially drive up prices, Nishimoto said. He declined to comment on the company’s plans to build a production line.

Almost lost in the back hall was an impressive booth from Field Emissive Technologies of Japan, featuring a 17.7-inch FED display with 1280x720 resolution side-by-side with a small CRT monitor. In addition to excellent color shading and grayscale reproduction, the company also showed a 240-Hz refresh demo against a 120-hz LCD monitor (not even a fair fight) and boasted 1/3 the power consumption of same-size LCD glass. According to company representatives, a 23-inch 1080p model is in the works for NAB 2009.

Theoretically, should this eiminate the "sample and hold" effect for those who suffer from it?

Theoretically, should this eiminate the "sample and hold" effect for those who suffer from it?
It depends on how it makes a picture, as there are so many ways you can make a FED. If it pulses a super bright image and has slow decay phosphors (as CRT does) then it'll behave like a CRT on motion. PWM modulated it'll look more like a plasma or OLED. If it uses sample and hold with lower output phosphors then the image won't be so snappy.

From the photos it is clearly passive matrix (SED is also). Therefore, as Carled points out, it will look very much like a CRT regarding motion.

I am all for SED and FED tv's. Failing that, how difficult is it to build a passive matrix HDTV LCD, so that it has CRT-like motion???

Both active and passive matrix designs can switch fast enough for CRT-like motion.

FED-TVs With Carbon Nanotube Technology Could Supersede Plasma And LCD Flat Screens

ScienceDaily (Nov. 23, 2007) — Just as silicon is the wonder material for the computer age, carbon nanotubes will most likely be the materials responsible for the next evolutionary step in electronics and computing. Their extraordinary properties have identified them as having the potential to revolutionise many technologies.

In particular, it is widely believed that carbon nanotubes will take electronic devices to the next level. Many people expect the hugely popular LCD and plasma screens of today to be replaced by field emission flat screen displays (FED-TV). FED-TV's take all the best aspects of CRT's, LCD's and plasma TV's and roll them into a single package. While the technology exists, manufacturers are at present unable to compete with LCD's and plasma displays on a cost basis. However, carbon nanotubes have the ability to change all that.

In order to incorporate carbon nanotubes into devices like these field emission flat screen displays, an intimate knowledge of the properties of various forms of carbon nanotubes is invaluable. Researchers from University of Latvia, University College Cork, Trinity College Dublin, University of London and Mid Sweden University have just published work characterizing the conductive and field emission properties of single and multi walled carbon nanotubes.

In this research the conductive and field emission properties of individual single and multi-walled carbon nanotubes were assessed using an in-situ transmission electron microscope-scanning tunnelling microscope (TEM-STM) technique. The nanotubes were grown by chemical vapour and supercritical fluid deposition techniques.

Experimental field emission characteristics for all carbon nanotubes investigated fitted well to the Fowler-Nordheim equation when different work functions were applied. Differences in field emission and conductive properties are analysed and related to the structure of the carbon nanotubes. The method presented can be applied in order to make in situ selection of carbon nanotubes with desired properties for specific electronic applications.

The researchers found that conductivity and field emission properties were nanotube structure dependent. The structure of the outer layers and whether or not the nanotubes were filled with C60 molecules were key factors in determining the properties of the carbon nanotubes.

These findings make a significant contribution to the understanding of the structure/property relationships for carbon nanotubes, which in turn bring the next generation flat panel televisions and monitors a bit closer to our lounge rooms and offices.

High-Definition Carbon Nanotube TVs
Motorola's new nanotube display technology is almost ready for prime time.
By Kevin Bullis
Carbon nanotube displays that outperform today's flat-panel televisions are ready to move out of the lab and into factories, say researchers at Motorola (http://www.motorola.com/content.jsp?globalObjectId=6582-9298-9303). The carbon nanotubes make possible high-definition TVs with the color, contrast, and fast response characteristic of bulky screens based on cathode-ray tubes (CRTs), but in a flat-screen format.
The new TV screens are a nano version of the field emission displays (FEDs) developed by Motorola and others during the 1990s. Although that technology produced dazzling prototype displays, it cost too much to compete with liquid crystal displays (LCDs). "It didn't make sense to build a factory [for conventional FEDs]. The cost [of LCDs] was halving each year," says Kenneth Dean, who leads development for carbon nanotube displays at Motorola. However, he says, carbon nanotubes have given field emission technology a second wind by yielding cheaper components that can be manufactured more easily.
Motorola does not intend to build its own factories to manufacture the displays, so the company is now in licensing talks with several manufacturing companies. James Jaskie, chief scientist at Motorola, says two companies in Asia are now building factories to produce carbon-nanotube-based displays that may use some aspects of the Motorola technology.
Field emission displays, like CRTs, work by directing electrons at red, green, and blue phosphors arrayed on the screen. But rather than using one electron gun positioned a foot and a half behind the screen, as in CRTs, field emission displays use millions of tiny electron emitters placed within millimeters of the screen. Early field emission displays used sharp metal points for the emitters, but these were difficult to make over large areas, and they required such high voltages that expensive electronics were needed to control where and when pixels lit up.
Carbon nanotubes, however, are so thin that they make it possible to lower the voltage and use cheaper electronics. "We're using an electric field to pull electrons out, and the taller and sharper it is, the lower the voltage you need," says Dean. Because the nanotubes perform so well as electron emitters, they can also be placed farther from the control electronics, which Dean says should make large displays easier to produce.
But working with nanotubes brings challenges of its own. Researchers needed a low-temperature method for making them that would not melt the glass in the display; they also had to find a way to distribute the nanotubes uniformly, since the eye can detect subtle differences in brightness between neighboring pixels. Finally, the nanotubes must be spaced at a specific distance from each other, since they work best when they are not too close to neighboring nanotubes. Dean says the Motorola solution involves materials that self-assemble to form tiny particles just three nanometers in diameter. Exposed to a hydrocarbon gas such as methane, these particles catalyze the formation of nanotubes three nanometers in diameter, much smaller than the 20-nanometer tips used before.

These problems solved, the technology is now ready to move out of the lab. "We're through the laboratory demonstration phase," Jaskie says. "Manufacturing development--building a factory and having all the manufacturing equipment up and running--is the next big step."

I am all for SED and FED tv's. Failing that, how difficult is it to build a passive matrix HDTV LCD, so that it has CRT-like motion???Passive Matrix and LCD don't mix too well because in Passive matrix each row of pixels is only active when scanned by the respective row and column drivers. So in a 1080 line LCD each row of pixels only has 1/1080 of each scanning period to activate. With LCD slow response this makes it difficult to get a useable brightness; causes severe ghosting; and induces cross talk.

SED and FED are perfect designs for passive matrix as they can be run like a CRT in impulse mode.

Both active and passive matrix designs can switch fast enough for CRT-like motion.


Hi all,

Isochroma, thank you for your reply, much appreciated. In the OLED technology thread there was at some point a discussion about LCD motion. However I am still confused. What do you mean, by 'active matrix design can switch fast enough for CRT-like motion'? Do you mean the right design can eliminate motion blur in the sense of the 'sample and hold effect'? How and when? In my opinion top of the range Sony lcd tv's produce absolutely beautiful picture with the right feed- when there is no movement on the screen- but the faster the objects move the less resolution and more blur occurs. It is anti-CRT-like motion. So what design can switch fast enough??? The one that only exists in theory and has not been built yet? Or maybe such a design exists but is expensive and would make a tv set cost $15,000? Or do you mean a design w/ strobing LD LED's? Please explain. Thank you in advance. I love the sharpness of HD LCDs but I despair over their motion, the horrible 'sample and hold' effect.

Both active and passive matrix designs can switch fast enough for CRT-like motion.

Or maybe you mean LCDs with 1,800 Hz and such as a way of improving the motion? I really want a fast switching LCD.

The important thing to realise is that the addressing scheme and the sampling scheme are completely different things. It's the way these two things combine that gives a display type it's stereotypical look.

Don't get too caught up on sampling frequency; it's a means to an end, not an end in itself.

I see mentions of carbon nanotubes here and no mention of what they are really for. I am assuming that they are used for the Emmiter for the pixel.

I also see Moto and some other organizations listed here as the developers of this technology, so do we have to worry about Nano Prop popping in and sueing like they did with Canon?

Canon still is going it alone with SED, but it looks like maybe FED may beat it. Despite the fact that Sony has come out with a small OLED set, testing has shown that it has longevity issues with the colors and again the blue is the problem. Does anybody here really beleive that OLED will become commercially viable in larger screen sizes before one of the other technologies like FED takes off?

So...What about the longevity? If it doesnt have any kind of problem with that, i believe it will become widespread much sooner than OLED.

Bump!!

So...What about the longevity? If it doesnt have any kind of problem with that, i believe it will become widespread much sooner than OLED.

I have not seen any figures quoted, but I expect that the panel should hold up at least as long as CRT displays. Some of those have lasted up to twenty years of daily use. If I uncover anything specific, I will post it on this thread.

Pioneer (http://www.eetasia.com/ART_8800291074_480200_NP_8a91b997.HTM) Corp. has started negotiations to sell its plasma display panel factory to a flat-panel developer funded by Sony Corp., according to a report from JCN Network. Pioneer's factory in Kagoshima Prefecture, southern Japan (http://www.eetasia.com/SEARCH/ART/Japan.HTM), will stop PDP production in January 2009.Pioneer and Field Emission Technologies (http://www.eetasia.com/ART_8800345883_480700_NT_b8e284b7.HTM) Inc. have yet to agree on the value of the deal, but it is estimated to be from $188 million to $282 million (20 billion to 30 billion yen). According to the report, which cited sources familiar with the matter, some of the factory's 600 workers may be hired by Field Emission Technologies, which develops field emission displays (http://www.eetasia.com/SEARCH/ART/field+emission+displays.HTM) (FEDs) for next-generation flat-screen TV sets.
The Sony spin-off has established a mass FED production technology and now needs a production foothold. The company hopes to begin full output by end of 2009 if it buys the Pioneer factory. The factory is expected to ramp up 10,000 units of 26-inch panels monthly.

Too little, too late. OLED has already won the race, but even it may yet be drowned in the rising tide of LCD.

http://www.itexaminer.com/PCs/tabid/75/articleType/ArticleView/articleId/1067/Sony-all-set-to-replace-LCDs-with-its-FEDs.aspx


Keeping an eye on the increasing demand of clear crystal view globally, the Field Emission Technologies bit of Sony is looking forward to go for mass production of FEDs (field emission displays) by the end of 2009. FEDs are believed to be first of its kind that give improved picture quality and energy-wise, are more efficient than LCD screens.

Unlike LCDs, FED panels do not require backlighting as these new kind uses the same light-emitting principles as cathode-ray tubes.
Sony will invest between $180-280 million (20 to 30 billion Yen) in the Kagoshima plasma plant of Pioneer to speed up the production of FED panels. The Field Emission technologies will retain some employees of Pioneer. Sony holds a 37.8% stake in the company.
About 10,000 26-inch FEDs will be built in the initial phase of production. The target market will be medical and broadcasting equipment manufacturers. This next target would be the television market with the production of 60-inch panels.
The company has projected an annual sales target of $235 million (25 billion yen) in couple of years.

http://www.about-electronics.eu/2008/07/03/sony-company-to-mass-produce-fed-displays/


Less than a year after it launched the world’s first OLED television – the XEL-1 – Sony is looking to compete with an entirely different line of next-generation displays called FEDs. Sony affiliate Field Emission Technologies is set to begin mass-production of FED (field emission display) panels by the end of next year, according to Japanese media reports.
A spokesman for Sony Japan told us, “We are aware that Field Emission Technologies is in negotiation with Pioneer regarding mass-production of field emission displays, however this does not have any implications for Sony’s existing relationship with FET.”
Where the XEL-1 measured just 11 inches across the diagonal, FET is aiming to produce 10,000 26-inch FED panels each year at the plant in Kagoshima. These will be for medical and broadcasting use first, but 60-inch consumer televisions may follow soon after.

Too little, too late. OLED has already won the race, but even it may yet be drowned in the rising tide of LCD.

How exactly has OLED "won the race"? The XEL-1 may already be on store shelves but it is little more then an expensive (for it's size) technology demo. With many manufacturers claiming 3+ year periods just to get sub 40" OLED displays on store shelves the market is still wide open for new technology. If they can get 40+ inch FED panels rolling off the lines and into stores within a year or two and aggressively market their advantages over LCD and plasma they could really shake things up.

I anybody heard if these FEDs will have any problems with burn in or IR?

FED uses tweaked CRT phosphors, so FED should have similar burnin characteristics as CRT.

That's absolutely right. OLED is still a dream and probably will remain a dream especially if FED by Sony goes on sale in late 09.

Here's a comment posted on gizmodo by s'one calling themselves 'FED TV reviews':

"The XEL-1 OLED TV is obviously a concept tv. I tried watching a hockey game on one I got to review and I COULDN'T SEE THE PUCK! However, Sony is forging ahead with both OLED and FED."


I want FED.

Methinks OLED is DOA!

Samsung has been working (quietly) on FED too. Hopefully Sony's announcements will motivate Samsung to show their own FEDs at CES09. Wouldn't that be lovely?

Thanks for the links. It looks like all they are making public so far is the patent info.

I guess we will just have to wait for them to demo a working model. I sure hope they follow through. A bit of competition might provide Sony with a sense of urgency. As long as they are the only one with a panel coming to market they can charge more, and take their own sweet time introducing consumer models.

This thing obviously has way a higher chance of reaching production than SED TV will ever be (unless you believe in Auditor55's lunatic claims).

With that said, I am surprised when the FED people said:

"200-240 fps supported..........as early as the prototype stage!!!!!"

Wow, that's like how OLED can achieve amazing contrast ratios (equivalent to that of a Pioneer Kuro TV or even the most expensive LCD TVs to-date)........and that's just a first-gen product (the one from Sony).

If they can achieve so much in this early stage of production, what more will it become after 5-10 years?!?!?!?

I anybody heard if these FEDs will have any problems with burn in or IR?Since it uses phoshors, there CAN be burn in. Phosphors age when they are exposed to radiation and will dim with use.

So if it's possible for FED to have burn in, then I have to assume SED will have burn in too? That sucks. I have a Sammy DLP that I've had since 2004 and I was willing to hold off on buying either the XBR8 or the 950. sigh. SED is not dead, barely breathing but not dead. Check out SED-TV-reviews.com. I just want to get a tv that I'm totally satisfied with. I know this question is off topic but I get this type of delayed reaction when I'm playing Gears of War. Like I got sombody in my sights and I'm ready to kill them and BLAM! Off goes my head. I know I pressed the fire button and I should've had the kill. Is that the tv or just a messed up host connection?

Supposedly the FED panels are going to have much improved phosphors that will be far less vulnerable to burn in. We will have the 26inch business displays being released next year, so they will give us a better idea of how resistant to burn in they will be, long before consumer models will be available for purchase.

Please do not bring the SED topic on to this Official FED developments thread. That subject has been beaten to death on several other threads, and there is no product scheduled to be released.

Stay on FED topic please.:)

even tho these 26 inch models are being labeled as business displays think determined consumers like me might be able to get hold of them
i know they will be expensive but im willing to pay up to £500-700 for one

i love my CRT and it has served me well but i desperately need something bigger and flatter and current LCD's are not an option :(

I expect that the first generation of those panels will be closer to two thousand, than to your price range. Keep in mind they are talking about selling them for medical imaging etc. That is the high priced arena. They will charge hefty prices to businesses that can afford it, in order to recoup their development and manufacturing costs, and to fund further expansion.

Have you searched for a refurbished large CRT high resolution monitor, that would tide you over?

Expect to pay mucho deniro for that FED. From the applications involved it sounds like Sony Broadcast & Professional Div. will be the first to offer these 26" FED monitors, and from that info and my own past experiences of owning Sony Professional Monitors, I can tell you they ain't gonna be cheap. Didn't last year's little $2500 Sony 11" OLED TV give you a hint??:D

Pretty good article. For quite some time I've been telling people that Plasma is not LCD's biggest competitor, but rather OLED and/or FED. At this time, Plasma only has displays in the sizes larger than 42", and Pioneer doesn't even offer that size any longer. LCD's biggest market is the under 42" sizes, all the way down to the itty bitty cell phones. Imagine OLED taking over the tiny screen market in cell phones, iPods, laptops, computor monitors, etc. Then here comes FED starting things off in the 26" display sizes. What's left for LCD??...not much.

The question has been asked several times here if FED or OLED is the future. I know that several of you will have issues with this but I think OLED is, not FED.

While companys continue to work on FED, beleive it or not there is a OLED set out there for sale now. Yes it it small, overpriced, so-so resolution and may suffer from lifetime issues (if anybody keeps one long enough), but it is for sale now.

After having seen one it is impressive. Blacks are great, color is good, brightness is good viewing angle is good. I see issues any claims that FED will be on the menu at next years CES. There may be a couple of FED displays there but, does that mean that they will be for sale the next month? NO.

Everybody remembers how many times Canon/Toshiba had SED screens up and running at CES and dispite Auditor55's claims, I have not been able to find one in a single store. At least there is a OLED model that the manufacture was able to bring to mass production, integrate, and offer for sale to the public. Until FED passes this test, it is just one more tech that has promise, but no delivery.

That OLED in the stores is from Sony. That is the same company that is purchasing Pioneer's Plasma plant to start manufacturing 26 inch FED displays. Sony has a history of delivering new products.
Canon has never brought a single TV, of any kind to market, so your comparison is meaningless.

Sony is planning to market both OLED and FED displays, so they clearly see a future for both technologies. I have more faith in their judgment, since they have a long history of delivering the goods, than I do in yours.:)

This thing obviously has way a higher chance of reaching production than SED TV will ever be (unless you believe in Auditor55's lunatic claims).

With that said, I am surprised when the FED people said:

"200-240 fps supported..........as early as the prototype stage!!!!!"

Wow, that's like how OLED can achieve amazing contrast ratios (equivalent to that of a Pioneer Kuro TV or even the most expensive LCD TVs to-date)........and that's just a first-gen product (the one from Sony).

If they can achieve so much in this early stage of production, what more will it become after 5-10 years?!?!?!?

The lastest reports have Canon still moving forward with SED. Since you're always in the Kuro forum you probably are not aware of that.

Japanese company plans FED panel production by late 2009

Excerpt. (Use link to read the entire article)
"Fourteen hundred Spindts are required to keep pixel brightness differentials within 2 percent," said Hiroyuki Ikeda, general manager of marketing at FE Technologies. Using this structure, the electric current per Spindt decreased while Spindt operating lifetime was improved, the company said.


The mission of the Sony spinoff is to investigate FED business opportunities, said Shohei Hasegawa, FE Technologies' president and CEO. "The idea of becoming independent was triggered by successful development of spacer materials," Hasagawa said.
FED technology requires a high vacuum level. Spacer material is necessary to maintain the shape between the anode and cathode substrate against air pressure. "We needed to develop electrically- transparent material, which neither charges itself nor becomes conductive, but can maintain an electro-field between anode and cathode, in parallel," he added.
To help it meet the mass-production deadline in late 2009, FE Technologies will acquire Pioneer's Kagoshima plant by the end of 2008. The Japanese company will invest $183 million to $274 million (20 to 30 billion yen) in manufacturing equipment.
FE Technologies will use the company's fourth-generation glass substrate (730mm x 920mm). Each substrate will yield a pair of 26-inch panels.
The company said it will proceed with the mass production of FED panels using 5,000 glass substrates per month. The initial application for FE Technologies' 26-inch FED panels will be as "master" monitors, used by TV broadcasters to check picture quality. Neither LCDs nor plasma displays are said to satisfy the high quality standard required by such master monitors.

These things have more lives than a cat. FEDs were all the rage in the 90's when they promised and failed to deliver a display revolution. OLED and SED have since promised to deliver the same revolution, and have also failed. :p

I know that you have a built in bias for some reason against Canon, so I forgive that. Never understood it though, some time in the future send me PM.

It is not Sony really that is purchasing the old plasma plant really, it is the spin off of Sony. That makes it completely different. If Sony really thought it was such a good idea they would take it to market themselve along with a partner like Pio or Panasonic.

By spinning off FED they get the best of both worlds, they probably have an exclusive agreement to sell the product if it suceeds and if the company blows through the money they have with no fruit then Sony is not out so much.

I look at the spin off as Sony saying that they aren't sure about the viability of the technology, esspecially in mass production. Mass production is where most of these things fall apart. This is just IMHO, you may be right, but that again is based on your opinion as well.

These things have more lives than a cat. FEDs were all the rage in the 90's when they promised and failed to deliver a display revolution. OLED and SED have since promised to deliver the same revolution, and have also failed. :p
Agreed in part.

I think that OLED has a future somewhere, somehow, it is at least used comercially. SED while maybe still being researched is for all practical matters in FPD is dead. FED is a unknown.

This is a FED developments thread, and is not intended for debating the merits of OLED. There is a thread dedicated to OLED developments. Let us stick to the thread topic please.:)

Field Emission Technologies was spun-off from Sony in 2006. Sony still owns around 36% of the shares but FET is essentially it's own entity at this point.

Sorry greenland didn't mean to go off on that, just my opinion. Besides the current state of FET and the activities they are engaged in, is there allot of interest in FED? Does FET have competition out there?

This company recently announced that they are jumping in, but they look like they are still a long ways behind FET, since they have already demonstrated a 19inch panel, and have announced a 26inch production time line.

Samsung took out a US patent, just four months ago, but have not made any further announcements.

They have a vague FED piece on their Korean site that does not reveal much, but it looks like they are certainly continuing with basic research.

Bump!!!

Anyone know how FED panels compare weight-wise to CRTs, Plasmas, or LCDs?

Another company in the UK called Ikegami is planning on releasing their own FED based monitors next year.

http://www.ibc.org/cgi-bin/ibc_dailynews_cms.cgi?story_no=25561&issue=6


FED monitor imminent
Ikegami has a prototype flat panel master monitor on show that it believes will offer the picture quality of a Grade 1 CRT, without its disadvantages. The field emission display incorporates real phosphors, "so black is black and colourimetry is correct, just like a CRT, but unlike the CRT it doesn't have geometry issues or edges going out of focus," explained Mark Capstick, general manager, Ikegami Electronics UK.
The FED is aimed at top-end, high quality monitoring as a replacement for Grade 1 monitors, and meets the requirements of the EBU and the Association of Radio Industries and Businesses. It uses more than 10,000 nanocone emitters to illuminate each pixel and promises to be low on power consumption and relatively thin.
The new monitor is not expected to be available until late next year, when it is likely to be between 24 and 26 inches in size. Ikegami needs to establish a suitable manufacturing facility in the interim.

FED panel developers had to cancel their production plans after being unable to obtain credit to purchase a manufacturing plant from Pioneer.

FET pulls out of Pioneer plasma deal

Kyodo News
Field Emission Technologies Inc., an affiliate of Sony Corp., has given up on buying Pioneer Corp.'s plasma panel plant by March as planned, sources said Thursday.
The company was apparently unable to raise the necessary funding for the purchase amid the ongoing financial crisis.
FET and Pioneer agreed on the deal for the Kagoshima Prefecture plant in September after Pioneer decided to pull out of the plasma panel business. FET planned to make its new flat-panel displays for use in broadcasting and medical services there from late 2009.
A field emission display, or FED, is a new type flat screen that produces quality pictures using less power, according to the company.
Field Emission had intended to take on about 180 Pioneer employees through the deal but now Pioneer will try and find jobs for those workers, according to the sources.
Field Emission was established in 2006 by Technology Carve-Out Investment LLP and Sony.

That plant might be available for cheap now.

That plant might be available for cheap now.

So might some of Sony's, so their spin off should try there first.

With the news of 'Pioneer's PDP closures',TBC, would it not be grand if they announce on Thursday that their top engineers are now going to work for the FED off-shoot company, with most of their KURO, FUGA IP intact?

So best case scenario - PDP production ends,expertise farmed out to Panasonic for 10G, ECC, BUT ALSO to the FED off-shoot company - with an announcement that KURO (2?) will be b(l)ack and better than ever in 2011 with Piosonic for large tv's, FED's for monitors, smaller screens!

We can dream the impossible dream...:D

Futaba Corp. FED panels demonstration.

Watch the video . It is in two parts, so after the first part ends, wait for the second part of the video to start automatically.

Perhaps it can be adapted and scaled up for HDTV panels.

Sony Corp's FED spinoff, Field Emissions Technology, has announced that because it has not been able to obtain the financing to acquire a plant facility, and go into production, it is going out of business.

FFS :mad::rolleyes::(

wow cool what's the price?

As the OP of this thread, I have now become fully convinced that FED is dead, and is unlikely to ever come to market. So I am going to have this thread closed.

"It seems that FED (field emission display) (http://en.wikipedia.org/wiki/Field_emission_display) technology is not going to be the successor of LCD and plasma. Toshiba gave up on FED and SED (http://en.wikipedia.org/wiki/SED_display), respectively, as early as January 2007. The company stopped a joint venture with Canon, which also seems to have more or less stopped development in that area (at least there were no FED or SED-related news from Canon in the last couple of months).
Now FED gets the Sony axe, too.
Sony said last summer it wanted to buy a plasma TV factory from Pioneer in Japan. The factory was supposed to be rebuilt into a FED display factory, but Sony has abandoned the plan now. In addition, the company will close FED Inc. (http://www.fe-tech.co.jp/en/index.html), a spin-off entity entirely focused on FED production. FED Inc. was founded late 2006 for $26 million.
Sony began experimenting with FED technology as early as 1998 and showcased a 13-inch prototype TV at SID (http://www.sid.org/) 2001. But even though Sony said it plans to boost FED production last July (http://www.crunchgear.com/2008/07/02/sony-to-boost-production-of-tvs-with-fed-technology/), FED was never commercialized. And it’s doubtful that any other company will dare to mass-produce large-size FED displays now."
