15" OLED Display Prototype

crwulff writes "The Rochester Democrat and Chronicle today is carrying a story about Kodak's newest OLED display venture. Unfortunately only a prototype to look at here but at least it is on the way in a couple years." It's worth it just for the photograph. Maybe best to hold off on a plasma TV ...

I think these are a neat product, but I don't see it replacing my CRT anytime soon (even after its release) for various reasons. It is still so long until production and a lot can happen, it might as well be vaporware.

Re:Better pictures, more info

[kwashiorkor]

An interesting comparison of the current flat-panel display technologies. It's not exhaustive, but it gives you a good 20,000 foot view. Note that this is on the site of an OLED tech competitor, trade named "iFire" which is thick-film transistor based so it's slightly slanted.

The iFire technology is pretty cool too. Seems to be a lot less expensive than OLED, though it's not as bright so less useful for genreal purpose displays. Both techs have been in development for years with very little, commercially, to show.

Apparently TDK and Sanyo are both pursuing potential iFire solutions, though I'm sure all display manufacturers are currently investigating all of the alternatives. Way too soon to throw all one's eggs in one basket.

Re:Better pictures, more info

[ReC]

Note that the answer to the "what about blue lifetime" is at that site: currently, Kodak has materials which hit 40000 hours for red & green, 20000 hours for white, and 10000 hours for blue (this is hours until 1/2 brightness).

2 to 3 years off?

[Powercntrl]

By the time this is for sale, hopefully good "old fashioned" LCD technology will be more affordable. I'm already using a 15" KDS RAD-5 and my friends are like "Wow, a flat panel, those are still too expensive for me." I like my flat panel though... Once you go flat, you never go back. Everything else just looks blurry.

Re:2 to 3 years off?

[larsoncc]

Now, I don't mean to be a CRT bigot, but...

Apparently, you don't switch resolutions much. If you get a LCD out of it's native resolution, it really starts to look blurry.

As a person doing web work (not to mention games, games, games!), I switch resolutions fairly often. IMHO, I've found that my "high-end" CRT, which costs LESS than even a basic LCD, displays much better, and is far more flexible.

Re:2 to 3 years off?

[Wyatt Earp]

I really like my 17" iMac LCD.

All that deskspace returned and that swinging arm and then thin little screen, it rocks.

Re:2 to 3 years off?

[Powercntrl]

I've found that my "high-end" CRT, which costs LESS than even a basic LCD, displays much better, and is far more flexible.

More flexible, yes... I'll give you that. You can't beat a CRT for quick refresh rates needed for serious gaming and a good picture in any supported resolution.

What a flat panel LCD monitor lacks in resolutions, it makes up for in display consistency. There is no pincushioning, no color seperation problems, the picture fills the entire screen perfectly, a horizontal or vertical line of pixels is perfectly straight and there is absolutely no flicker. Once you get used to looking at an LCD on a regular basis, the flaws in CRTs really start to become more apparant. I'll admit they're not for everyone, but for mostly browsing the web, wordprocessing, cropping and resizing images and the infrequent game or two, you can't beat an LCD.

Re:2 to 3 years off?

[drightler]

I have used LCDs many times, laptops and desktop, and I just can not tolerate the pixels, everything always looks blocky. They are great for space saving though, it certainly would take up less space than my 21" CRT.

Re:2 to 3 years off?

[aronc]

Once you get used to looking at an LCD on a regular basis, the flaws in CRTs really start to become more apparant.

I used one at work for a few months, ever did like it all that much. The delay in switching colors on and off lead to nasty ghosting effects on the viewsonic we had. Everytime I used pageup/down on a page of high contrast (like say, text.. particularly white on black text) it would see some blurring for half a second. Not too bad most of the time, but enough to give me a headache if I read pure text for more than an hour or so.

Re:2 to 3 years off?

[doi]

What a flat panel LCD monitor lacks in resolutions, it makes up for in display consistency.

True, they're very consistent in smearing and ghosting my mouse pointer whenever I move it more than 1/4" at a time.

There is no pincushioning, no color seperation problems, the picture fills the entire screen perfectly, a horizontal or vertical line of pixels is perfectly straight and there is absolutely no flicker.

Nor do CRTs suffer these problems, if you spend a whopping 30 seconds to adjust any of these abnormalities that might appear. Certainly none of them are permanent, and once they are set you never have to touch them again.

BTW, with a CRT you DON'T have a single dead pixel here and there like an LCD has. I have yet to see one laptop or one LCD flat panel that doesn't have at least one dead pixel, and ALWAYS in the center of the screen. And I don't know about you, but I can ALWAYS see the RGB pixel pattern on an LCD, and it's incredibly distracting.

Re:2 to 3 years off?

[topham]

Actually, I do have a dead pixel on my CRT.

It is a crappy monitor though, and several years old.

Re:2 to 3 years off?

[default luser]

LCDs still have one serious problem that CRTs havn't had for years. For the most part, LCDs have brightness levels and contrast leves out of sync with CRTs. TFTs are much brighter than CRTs, yet are typically lower contrast. This makes the images a bit more washed out ( even on a well-configured display ), and it means more eyestrain for the user. When your job depends on your being able to keep your eyes glued to the screen, eyestrain is the enemy. Quality CRTs are the best solution, for now.

Re:2 to 3 years off?

[aronc]

The stuff Apple has is great. Also check out the high-end Samsungs. As it is, your opinion is both dated and uninformed.


Dated perhaps, not uniformed as I didn't try to extrapolate my one experience to all LCDs. Just posting my personal experience which is why I was careful to mention the brand, although it was a 17 inch which I should have mentioned.

Re:2 to 3 years off?

[Anonymous Coward]

In my opinion, the only legitimate complaints I hear about LCD are the following:

Refresh, fixed resolution and price. Of course, these are important factors. I just feel that a lot of users seem to be basing their opinions on LCD off of 'poor' or 'old' LCD displays like I originally did. A lot has changed.

I have a 24inch Sony CRT. It's a beautiful CRT monitor, however it can and does suffer from electro magnetic interference like every other CRT. Because CRT monitors are analog devices, that's kinda inevitable in some homes/offices unless you rewire the entire place or spend a lot of money on shielding.

LCD's simply don't have this problem. To see where I'm coming from - check out an LCD such as Samsung's 180T if you want to see a nice LCD. It ain't perfect for all things (such as high resolution requirements) but for typical computer use, it ain't bad at all. If its still not right for you, understandable, but please - don't judge LCD off of 5 year old technology or bargin bin 15inch LCDs.

If it weren't for the LCDs typically being lower resolution (and smaller because of the price) I'd probably use LCD and ditch my 24inch sony CRT. Have you guys seen an LCD with a 1600x1200 native pixel resolution with a wide viewing angle? It's like nothing you've seen. CRTs can't come close when it comes to how crisp these displays are.

Re:2 to 3 years off?

[Dun Malg]

Once you go flat, you never go back. Everything else just looks blurry.

That all depends on the kind of tube monitor you had before. If you have a 15" Shamrock, anything is an improvment. If you have a decent monitor (I have a 21" Sun w/ aperture grille) moving to LCD is not an improvement in clarity.

Since they are projecting a market in 2-3 years, I guess I should start saving now. I wonder if this will be able to make practical (more or less) the wall screens that were in "Total Recall"?

Organic?

[Tablizer]

Does that mean it will get moldy in humidity?

Re:Organic?

[kfg]

Just as moldy as the other organic compounds around your house, and in your computer, like the case of your existing monitor.

Organic != biodegradable, it means containing carbon, like a diamond, which is about as far from biodegradable as you can get.

OLED's are are made in polymer sheets rather than in individual chips of silicon. Ultimately this will make them cheap, rugged, rollable and producable in almost arbitrary sizes, like wallpaper.

I feel a Ray Bradbury story coming on.

KFG

Re:Organic?

[JohnRlI]

Organic != biodegradable, it means containing carbon, like a diamond

Organic does not mean containing carbon, and diamond and other puter-carbon compounts such as graphite or bucky balls are not organic. Organic means containing a hydrocarbon compount such as those found in oil, ie compounds with Hydrogen and Carbon (and also other elements).

The rest of the comment I agree with ;)

Re:Organic?

[Tablizer]

No problem: just drop in a few goldfish to eat the scum.

If the thing is organic then the fish will eat the monitor too.

Hmmm. I wonder if humans can eat it? Hey, there we go, editable monitor underwear. If you don't like the way your mate looks, then just download a new set of T & A images to replace the real ones. (Except in that case, you then would NOT want to eat it because it would expose the originals again.)

After all, the adult industry is what sparks most consumer product revolutions.

Re:Organic?

[kfg]

Well yes, I worded that badly. I didn't mean to imply that diamonds were organic, merely that they were carbon.

I understand that many (perhaps even the majority) now except the definition of organic that you use, but all definitions of organic have always been controversial and even arbitrary.

In 1846 William Gregory ( Professor of Chemistry at U. Edinburgh) defined it thus:

"Organic chemistry is so called because it treats of the substances which form the structure of organized beings, and of their products, whether animal or vegetable."

This is pretty much what the common conception of the word "organic" still means.

In my day ( as a student, I'm still here actually) it was taken to mean any compound containing carbon in a covalent bond, thus the polymer teflon ( whose monomer is C2F4) was considered organic.

I suppose your definition will prevail universally in time because it makes more practical ( as opposed to historical ) sense in this day and age for both commercial and biochemical purposes.

However, I would like to point out in my defense that the carbon containing compound I specifically mentioned ( the material used to make monitor cases) is, in fact, a hydrocarbon compound.

Oh, and by the way, IANAC, IAAP, so what the hell do I know anyway.

KFG

Re:Organic?

[Joe Runde]

No it doesn't get moldy, but humidity is a problem for TFT substrates. That's why both LCDs and OLED displays need to be encapsulated (i.e. completely moisture-proofed).

Will they be able to compete with lcd in 2 years?

[icejai]

Kodak says the 15-inch screen is a prototype and won't be on the market for two or three years.

I wonder how cheap 15 inch lcd screens will be in 2 to 3 years. They're already falling pretty drastically already. And once these OLED monitors come to market, will kodak and sanyo be able to make a profit if these lcd screens continue to drop for 2 years? They could always make them bigger i guess.

Hmm... super-cheap wall-to-wall flat panel displays.

Yum!

If they list for a jillion dollars

[stratjakt]

I mean LCDs and plasmas aren't exactly flying off the shelves. (Sure they arent quite struggling either)

What I want to know, is this technology potentially cheaper? From what I've read it's gonna be even pricier.

Time for a new Tablet

[buttahead]

Looks like this would be great for a new tablet type computer. Reading books on this is easier than on a palm pilot, and since the technology uses little power, perhaps the batteries would last as long as the current palms. Another positive would be the slim size for reading during flights.

Re:Time for a new Tablet

[buttahead]

although, now thinking about the reading during flight... LCD screens are nice, as the guy across the aisle can't see your porn. the soon-to-be-new screen is supposed to much brighter... wonder if that means that the viewing angle will be improved.

Re:Time for a new Tablet

[shadow303]

If you would read the article, you would see that the new screen has an excellent viewing angle (165 degrees if I remember correctly).

The real question is price

[jbarket]

I mean, I'd love to have a plasma TV hanging on my wall, but I sure don't have that kind of money laying around. This looks like great technology, but I just hope it'll be available in an average user sense instead of just for people who have several grand sitting around just for a monitor.

Size too

[jbarket]

Considering the fact that it's only as deep as two quarters stacked on top of each other, it's also a great size. You could stuff average laptop components in a box under this thing and it'd still be ultrathin.

Arsenic is an element, and ammonia is NH3. Neither of them are organic. Organic molecules contain carbon. Better to say eating the screen would be like drinking gasoline or getting your mouth washed out with soap.

Of course, there is the little organic ion CN-, better known as cyanide.

I was going by the fact that peaches make arsenic and baby diaper make ammonia. Bother are by products of organic processes.

I'm sure there are more than enough examples of 'organic' poisons in the world!

Yes, the O stands for organic, which in this case

means *plastic.* Polymers are organic compounds, which means containing carbon, as opposed the the silicon of traditional diodes.

Re:These things make me nervous

[Teun]

bacterii

Yeah right, have a look at this this site

Organic light emitting diodes (OLEDs) are optoelectronic devices based on small molecules or polymers that emit light when an electrical current flows through them. They are being developed for applications in flat panel displays. A simple OLED consists of a fluorescent organic layer sandwiched between two metal electrodes. Under application of an electric field, electrons and holes are injected from the two electrodes into the organic layer, where they meet and recombine to produce light.

Or have a look here

Polymers by such tongue twisting names as polythiopene (red), polyfluorene (blue) and polyphenylenvinylen (green) consist of aromatic benzene rings which are pearl strung via carbon double bonds. As in conventional light-emitting diodes, the benzene electrons are excited by an exterior voltage of 3 to 5 Volt. In returning to their original state they emit light in a colour specific to their material which is exceptionally brilliant and soft.

3-color or 4-color?

[Smallpond]

The problem with LED displays is the reverse of the
problem for printing. In printing its tough to get
true black by combining cyan, magenta and yellow, so
they do 4-color printing, CMYK (K for black).

With LEDs, they want to do RGBW (W for white) to
get true whites, but the article doesn't say whether
they're doing three or four colors. Here's an
article on organic white LED:

Nature

Re:3-color or 4-color?

[kaphka]

White LEDs are interesting for other reasons, but as far as display technology goes, people seem pretty satisfied with the "white" displayed on RGB CRTs and LCDs. Why would an OLED panel be any different?

Re:3-color or 4-color?

[Smallpond]

Well, it adds a lot to the cost of a color CRT to
get good color convergence (avoiding color fringes
in area that are supposed to be white, for example).
I think that the same variations in output occur in
making LEDs, so the panel makers will have the
same color convergence issues. Only, on the LED
display, there won't be that neat "degauss" button
to make the picture go wonky.

Re:3-color or 4-color?

[MyHair]

Do you have any sources for that?

Frankly it sounds like BS to me.

Solid objects (like ink-printed paper) reflect light and therfore have subtractive coloring. The CMY inks don't absorb enough light to make black well, or at least they're hard to combine that way.

Lights, like these OLEDs, are additive color. I can't imagine them not being able to make white.

I've played with colored light bulbs in a darkroom before and you can make it perfectly white pretty easily. Mixing crayons to make black doesn't seem to work, though. Same concepts as far as I can see.

These things sound interesting. There is no constant backlight, so presumably you save a lot of enery buy using just enough to make the right color and brightness instead of powering a constant white and dimming it with LCDs in front.

Re:3-color or 4-color?

[RovingSlug]

OLED Display Materials:

In addition to red, green, and blue OLED materials, Kodak researchers have successfully formulated white-emitting materials. Using a dual emitting layer--each emitting in a complementary color--they have produced white OLEDs that yield not only an excellent white hue, but a good color stability over a wide range of light levels. The white hue is easily adjustable to any shade from pale yellow to light blue. The device life exceeds exceeds 20,000 hr (Figure 2).

Re:3-color or 4-color?

[mohaine]

BS.

True white light LEDs do not exist. LEDs put off light at only a single wavelength, which makes white light, which is broad spectrum, impossible. "White" LEDs are actually created by combining multiple complementary color LEDs into one. It may look like one LED, but it is realy just multiple LEDs close together. This would not help the RGB issue at all. May as well just use the RGB LEDs used for all the other colors.

Adding more primary colors to the mix would help though.

Re:3-color or 4-color?

[Ospeovedizer]

OK guys, this might be hard to follow, but try to stick with it:

White light does not exist. What we call "white" is just a color that seems to excite all your eye's receptors just about evenly. The fact that white light doesn't exist is the reason for the color "temperature" and "white points" you may have encountered if you calibrate your monitor.

In your post, you refer to a "true white" and I can assure you that there is no such thing. Our brains will actually filter any prevailing color out of what it sees and just call the result "white." If you've ever worn colored sunglasses you know that after a while, you just don't notice the color. Everything looks normal!

Our eyes, however, don't do the same to black. If light is coming off an object, then it's not black. This is why you need a K in CMYK: the C+M+Y just reflects far too much light to be called black.

This means that there is no need for a W in RGBW, since your eye will just accept any "white-ish" color to be "white" as long as it is present in enough of what you see.

I don't know if I explained myself clearly enough to make any sense, but I spent the past hour trying to get the wording right, and I'm not going to spend any more.

Re:3-color or 4-color?

[GigsVT]

CMY can make a real black, inability to make a good black is not the main reason that the K seperation is added. Screening a good black is difficult due to the non-linear way you see color, however. See below.

From the Color FAQ

BTW - I highly recommend the Color FAQ as a good primer.

25. Why does offset printing use black ink in addition to CMY?

Printing black by overlaying cyan, yellow and magenta ink in offset printing has three major problems. First, coloured ink is expensive. Replacing coloured ink by black ink - which is primarily carbon - makes economic sense. Second, printing three ink layers causes the printed paper to become quite wet. If three inks can be replaced by one, the ink will dry more quickly, the press can be run faster, and the job will be less expensive. Third, if black is printed by combining three inks, and mechanical tolerances cause the three inks to be printed slightly out of register, then black edges will suffer coloured tinges. Vision is most demanding of spatial detail in black and white areas. Printing black with a single ink minimizes the visibility of registration errors.

Other printing processes may or may not be subject to similar constraints.

Re:3-color or 4-color?

[Zathrus]

Lights, like these OLEDs, are additive color. I can't imagine them not being able to make white

They probably can make white - but is it efficient?

If they're having lifespan issues with the blue emitters (as they are according to older articles and other posts) then it may be far better to have a fourth element which emits white than to use the 3 separate elements to create white.

Just a SWAG - I'm not up to speed on the technology at all.

LCDs use about half the power as CRTs (Viewsonic). Sanyo and Kodak already have a 5.5 active matrix OLED that runs on 2 watts at 10 volts. While the 15 inch model would presumably use 9 times this, that's still close to half the power consumption of a similar LCD.

Size and weight....

[Spit_Fire1]

If this technology is as good as they say it is, this will do very well in the presentations and home theater markets if their price comes down(we know this isn't going to cost less than 900$ when it comes out) and they can support the sizes that plasma can. With their smaller size and weight it will be much easier to mount the televison to the wall and so digital picture frames and the like, however their increased price may stop that from happing in the next 15 years.

Size limitations?

[levik]

As you seem to have some knoweledge of the product, perhaps you can answer this:

In the era when 17" displays are standard fare for consimers, and 19" are preffered for proffessionals, is there a reason that the prototype was only a 15" panel? It seems like they would have gone for a 17" were they able to achieve this. Is there anything inherent in the technology used that makes creating larger sized panels exceedingly difficult?

Re:Size limitations?

[smithmc]

17-inch CRTs are standard for consumers. When it comes to LCDs, 15-inch is the norm, and when OLED comes out, it will most likely compete against LCD, not CRT.

Toshiba made a 17" prototype back in May that you can read about here.

Note the lack of blues in the picture

[shoppa]

Note that the picture on display in the article shows a floral scene of browns, oranges, and yellows. No blues. I'm guessing that the short lifetime of blue organic LED's is still a major factor.

That said, the original polaroid and technicolor processes also lacked any blue - they came later. If your goal is to reproduce skin tones, you generall don't need much blue; the eye can do remarkable things in compensating for lack of blue illumination but still making you think you see full-color.

Re:Will they be able to compete with lcd in 2 year

[Steffan]

I don't think they'll have a problem competing with LCD products. LCDs are a relatively difficult product to manufacture, and fab facilities are not cheap either, which means the investment must be recovered through product pricing. Once initial technical hurdles have been overcome, OLEDs should be much less expensive as well as more flexible, literally and figuratively.

I believe Cambridge Display Technologies as well as some other researchers are teaming up with the ink jet people to produce these kinds of displays by "printing" them on a substrate. If they can perfect that kind of technology, you could see a display nearly cheap enough to be disposable.

Why does a 15" LCD TV cost 3x an LCD display?

[swb]

I was flipping through a Crutchfield catalog and noticed that Samsung 15" TVs are like $1200, but a 15" monitor is under $400.

What gives? I can't believe that speakers and a tuner add $800 to the retail cost. Viewsonic sell a box that let you put NTSC on a VGA display for $100, another $20 buys you a set of speakers.

I keep waiting for the price to come way down, but it never seems to. I'm wondering if maybe the whole "flat panel TV" mystique enables them to charge way more for what would sell like hotcakes at $450 or so. I'd put one in my kitchen straightaway.

Re:Why does a 15" LCD TV cost 3x an LCD display?

People buying LCD TVs are the ones who have to have the latest crap, no matter what the cost. People with more money than brains. Meanwhile, people who buy LCD monitors also have to have the latest crap, but they're computer geeks, so they're a little more rational about it. ;-)

Re:Why does a 15" LCD TV cost 3x an LCD display?

[Jace of Fuse!]

That depends on which side you're standing in front of. The viewing angle in even the best of LCDs still leaves much to be desired, even if they have become very impressive in the past couple of years.

As far as image quality is concerned, some of the best CRTs and LCDs side by side are indistinguishable, so after having come to that realization it then boils down to how much space you have, and how much energy do you want to save.

Re:Why does a 15" LCD TV cost 3x an LCD display?

[AJWM]

I can't say I know the reason for the price difference, but possible reasons are related to the different requirements of an NTSC video vs computer VGA (SVGA, etc) display:

• different gamma curves
• different persistence (you don't want ghosting on the TV)
• wider viewing angle (without color change) for the TV
  

Re:Why does a 15" LCD TV cost 3x an LCD display?

[MSBob]

Err.. I beg to differ. Most LCD panels (the stand alone ones, not the laptop crap) have angles of around 170 degrees, horizontal and vertical. This is for all intents and purposes, as good as any CRT. If there is anything that can be complained about with modern LCDs it's the rise/fall time which may cause fast games to look blurred. I'm not a gamer so I don't care.

To me the quality of text on an LCD is so much better than a CRT there is no comparison. For the record I don't shop for low end displays: My old 19" Eizo CRT has just been replaced with a brand new Dell 2000FP and the difference in picture quality is absolutely astounding. The only snag is that for an LCD to shine it must be driven through the DVI input. For any LCD RGB~DVI==NIGHT~DAY

Re:Why does a 15" LCD TV cost 3x an LCD display?

[shepd]

>Viewsonic sell a box that let you put NTSC on a VGA display for $100, another $20 buys you a set of speakers.

There's more to it than that.

The NTSC convertor has to smooth and scale to the exact resolution of the LCD. At 15", it could be as high as 1400x1050. Next, it has to have a remote control interface. Also, they have to write software to control the TV tuner, and to control the various inputs. Then there's the V-Chip, payments to SRS, and myriads of other retarded crap they have to add (like being able to take insane static shocks).

After that $400 worth of stuff, they tack on an extra $400 for it being a niche product, just like anything else that doesn't get sold in quantity. For reference, compare the price of an XLR audio cable to an S-VHS cable. Both use the same amount of conductors (S-VHS is actually more expensive due to its shielding design), but XLR will cost you far more per foot.

There you go. :-)

Re:Why does a 15" LCD TV cost 3x an LCD display?

[swb]

$400 worth of stuff? C'mon, Samsung has a generic TV tuner board that handles all the input, output and tuning controls; the actual display adapter is just that, something to provide the specific hardware to drive the display. It's a modular design, it has to be to make any money selling TVs.

Even if its not a physically modular system and is a custom board for that application its like a lot of non-custom components that are re-used from other TVs or designs. Nothing here isn't used on other TVs with the possible exception of the display driver hardware, which is likely to be specific to this flavor of panel.

I'd grant them about $150 for the extra parts to make a good TV -- larger cabinet (includes speakers), the speakers themselves, the remote control, and any extra scan conversion hardware.

I do see the other $500 for just gimmick value.

I browsed Crutchfield's page for laughs and I notice that all the LCD TVs are now just nudging to the $1k levels at the 15" size. When they hit $500 on sale it could make an amusing replacement for a standard display, since most provide a VGA input.

What is the difference detween an inorganic and organic compound?.

After eliminating the guidelines I'd typically used, (and two I hadn't though of!), it appears that the best definition is indeed that "An organic compound is whatever an organic chemist says it is; an inorganic compound is whatever an inorganic chemist says it is."

Thus endeth the lesson. I hope.

Edge growth is a type of fill-factor defect. Single-pixel, and sometimes subpixel, defects are critical factors that determine display quality

will OLED replace LCD?

[u19925]

If we had OLEDs in market, people would be inventing LCDs. Both have advantages and disadvantages and it is not clear, if OLEDs would be able to overcome all the disadvantages it has against LCD. Here are few of them:

1. Color accuracy: Each colored dot on the screen will be composite of three LEDs. If their relative light output changes over time, you get color distortion. With LCDs, the transpanrency of each individual pixel controls color. Since this is known to be stabel for a long time (even before color LCDs came, this was known), this is not a problem.

2. Active matrix. OLEDs may be as hard to manufacture or even more than active matrix LCD.

3. Each pixel in OLED takes more current than in LCD. This makes OLED pixels more likely to fail.

It seems, the biggest advantage would only be in power comsumption and hence in portable devices likes laptop, PDA, cell phones etc. For others like home computer LCD screen, LCD TV, home appliances screen and other display, LCD would continue to be used for a long time.

Re:will OLED replace LCD?

[silverhalide]

Theoretically, this technology would be ridiculously easy to produce, since it should be able to be produced through an inkjet-type printhead. Pretty damn cool. If your screen dies, run to your printer, spit out an new one! (Oh I wish...)

Re:will OLED replace LCD?

[merlin_jim]

But, you forget OLED's biggest advantage:

The light-emitting layer is near the surface, with no polarization filters in between it and you... meaning that you can see it from any angle with no distortion!

Take today's LCD screen and look at it, even slightly off center, and you see color distortion.

environmental impact

[drunken monkey]

What is the environmental impact of manufacturing and disposing of these OLED panels? Are they safer then the current flatpanels and CRTs?

narbey

Re:environmental impact

[ebcdic]

Flat-screen IMacs have a warning on the box about disposing properly of the mercury backlights in the display, so they're unlikely to be worse than that.

Re:environmental impact

[the eric conspiracy]

My guess is that the impact would be less.

CRT's are made using a very high quality optical glass that is up to 40% lead. This is extremely bad from an environmental point of view. CRT's also consume a LOT of energy.

LCDs are better from an energy point of view than CRTs, however they all use some form of backlighting that may include a mercury vapor lamp. Mercury is very bad news, way worse than lead on a per pound basis, however much less is used in a LCD than lead in a CRT.

OLED's don't require backlighting so they should be the lowest energy consumer of all, and the articles I have read don't list any metals used in their production that are an evironmental problem. So OLEDs look very promising from both a energy and disposal point of view. The only questions would be the toxicity of the organic layer, and the hazards of the manufacturing process. Since manufacturing is likely to be in a pretty high quality environment in a limited number of locations, it is unlikely to be anywhere as significant as disposal. Unfortunately we don't know what the organic layer is going to be if and when these devices reach mass production, however I think that the likelihood is pretty good that it isn't going to be as bad as lead or mercury.

Re:Will they be able to compete with lcd in 2 year

[TastesLikeChicken]

They will first appear in places where LCDs first appeared, portable deviced (they're in phones in Japan NOW) then move up the tech tree to PDAs (probably already happening), Notebooks and tablets (we'll see those more next year) [all these are no brainers, as cost becomes close the mechanical simplicity [no backlight] and lower energy usage of the LEP/OLED devices makes a lot of sense ], then to monitors in 2-3 years. Only instead of stopping there (where LCDs are slowing down in getting bigger) I expect that we'll see LEP/OLED technology to produce bigger, brighter televisions in 3-5 years (so that DTV you need to have by 2006 will probably be one of these IFF they can get the lifetime of the blue lights to increase [so far they've been succesfull in doing so, but device lifetime is a killer for the TV application]).

Re:Will they be able to compete with lcd in 2 year

[jazmataz23]

Basic econ; at a certain point, the price stops falling. LCDs have been stuck at $300ish for a while now. Go to pricewatch and click "Monitors". You'll notice that the price for CRTs 17" and below are the same (17" have a higher volume, and so end up marginally cheaper). Notice too, that 15" and 13" LCDs are about the same. A new hard drive cannot be had for much under $50, and so on.

These are limitations of the manufacturing process; given a certain type of widget costs $y to make, everyone sells their widgets for at least $Y, regardless of their size. Unless the manufacturing process changes there will be a baseline price that the component will not go below.

However, I believe I remember seeing something about a manufafcturing change to LCD screens, so they may drop below their current $300 baseline, but they will hit a cost bottom; they won't continue down forever.

OLED/PLED have a long way to go yet...

[bagofbeans]

The killers are lifetime and power dissipation, neither of which match LCD. This is ok for small displays (games, PDAs), bad for big displays (laptops). The power dissipation rises drastically will high multiplex rations (read: bigger displays) because each OLED/PLED pixel is very capacitive compared with LCD.

See Philips Semiconductors' presentation at http://www.usdc.org/technical/downloads/Web_Report _0101/sld027.htm

The other cost killer right is the fact that the displays still need more than 5V to drive them, which is not useful in today's low voltage equipment. You can get a 200 pad chip-on-mylar LCD driver (look inside your old cell-phone!) suitable for a small (128 x 64 pixel) monocolour LCD from the likes of Seiko-Epson for little more than $1 at million type volume. Current OLED drivers come nowhere near that.

I reckon the technology is still 5 years away from becoming anything like mainstream. The hype may be to do with the fact the developers need to keep stimulating cash flow while the technology is still being developed. Also, although the displays do look gorgeous (bright, with unsurpassed viewing angle) the advantage of LCD for small low cost low power displays (PDAs, cell phones) is that they only draw serious power when the backlight is on. Not true for OLED/PLED, since they generate the light. Do you really want to press a button on your cell phone to see the time?

Does anyone know the relative expence of the technology? Is it supposed to eventually be cheaper to produce (after initial early adoption prices go doen)? Cause it seems to me that LCD technology still has yet to drop for reasonable sized screens (read: 17" and up).

I refuse to downsize from 20inches, and I refuse to pay more for my monitor than my entire computer. Dont even get me started on the ridiculous prices of the new crop of LCD/HDTV/Monitors... $1200 for 15" ?? Come on.

OLED may be good for some markets, but...

[Anonymous Coward]

OLED's with a blue sub-pixel half life of 10000 hours may find great uses in the tablet, notepad, and cheap laptop market. However, at that amount of half life, use in the desktop publishing and graphics markets and other places where color accuracy is important, it is not going to cut it.

I for one am not going to like to have to calibrate the monitor every few weeks. I know a gamer may not care if his character is a tad bit less blue each day. But I dont want to open a photoshop file I created a year ago and find it does not look the same as it did before.

With that kind of half life for blue, it may need some sort of auto calibration feature, and prehaps twice as many blue sub-pixels that can be turned on as the older-worn out sub-pixel degrades.

I have an OLED display in my car's CD player. Pioneer has used these pretty widely in their in-dash players. I can definatley vouch for OLED's usefulness when it comes to wide-angle viewing. Check them out.

Re:Ambiguous: how thick is it?

[targo]

The article says "The 15-inch screen is all of 1.4 millimeters thick -- about the size of two quarters back-to-back," but a SINGLE quarter is 1.75mm, so says [usmint.gov] the U.S. Mint.

Which makes it 0.14 inches. Which sounds reasonable to me. I guess someone mixed up metric and imperial here.

The AC post comparing "PhysicsScholar" to "PhysicsGenius" has hit the nail on the head. This is a pale shadow of a fine Slashdot spoof artist. Nothing to see here folks. Move along...

Re:The prototype still has issues

I've worked with the OLED team at Kodak for more than two years. They're selling small (2.2-inch) displays right now. The technology is scalable to the size of any low-temp poly substrate.

A JV between Kodak and Sanyo manufactures the screens. Right now the first line is up and starting to produce. EK is selling evaluation kits (screen, boards, documentation) for around $5K.

So you should be seeing small OLED displays in devices early next year. The 15-inch type screen is a few years off.

...then explain the way HUDs are supposed to work.

Last time I checked, there wasn't any real set way HUDs are made to work.

You're creating a display in your line of sight out of... say a cockpit window of a jet... using a thin, clear plastic lining inside the window... ...how is that not a HUD?

How about a Hybrid Tech...

[webbunny]

Someone mentioned in the thread that that reason OLED/LEP tech uses less juice than LCD is because only the pixels that need to be lit are lit, instead of lighting them all and then limiting the escape of that light.

And the problems with colour OLED/LEP that has taken time to overcome have been the lifespan of the blue pixels. Monochrome OLED screens have been around for ages, and are probably ready for production now.

So... How about a hybrid? Use a normal LCD layer with it's chromic filters, and a pixel array made of 3:1 rectangular pixels in RGB groups just like any other LED display. Then replace the backlight with the monochrome OLED, which has pixels that are square, 3 times the size of the pixels in the LCD layer and 'fit' behind a whole RGB group on the LCD layer.

Then the incoming video signal is split into a 'chroma' and 'luma' signal. The 'luma' signal is derived per pixel from MAX (R,G,B), and is sent to the OLED layer.
The chroma signal is processed so that the intensity values are scaled per pixel, so that the largest value in the RGB group is 100%, and this is then sent to the LCD layer. The LCD is now only setting the relative intensity of the 3 colours, not the absolute intensity, and black pixels (for instance) are not lit at all.

You then get some of the power saving of OLED, without the display slowly going more and more yellow in tint (think what happens if the blue output falls off faster than the red and green....). Plus, if you configure the LCD layer to pass light when it's not charged, if you get a pixel going 'dead', it just becomes monochrome.

The plastic/glass sheet in an aircraft HUD is a reflector. The most critical attribute of this reflector is that it must be completely transparent. OLED screens aren't completely transparent. The reason cars don't have HUDs has nothing to do with the cost. Nissan put a HUD-like projector in late 80's Maximas that displayed your speed on the windshield. They quit doing it, not because of cost, but because nobody liked it. A HUD is distracting. It takes quite a while to become accustomed to looking both at and through your windshield. It's not about price, it's about consumer resistance.

Huh? I never said they don't do it in cars because of any "military aspects" (whatever you mean by that). I said that the reason they don't put HUDs in cars is that it takes time and effort to become accustomed to using a HUD and until you're used to it it can be distracting and irritating. Very few people are willing to invest the time necessary (particularly when it's a feature they never needed before), so most simply turned it off and never used it. A feature that 95% of users find annoying doesn't make a good selling point, so there's no point in continuing to include it in the design. Cost was not the issue, so cheap OLED devices (which aren't usefull as HUD screens since they're not completely transparent) are not going to lead to HUDs in cars.

Counterpoint

[CreamsicleSeventeen]

1) Color accuracy could be adjusted with individual gain/bias controls just as in CRTs today. Adding "headroom" to the max subpixel brightness (build the display twice as bright as the control electronics will allow it to operate) would facilitate this kind of tuning and extend the lifetime of the display. Problem already solved by precedent and common sense.

2) Absolutely not. An LCD's matrix must be made on a transparent substrate. IIRC, that is why they are limited to amorphous polysilicon transitors and have a 30% yield. In contrast, any substrate that can support microelectronics can be home to an OLED. The design challanges (which I think revolve around heat) may remain, but making the support electronics shouldn't require anything that hasn't been possible years now.

3) Why would higher current be a cause of failure? That may make the active matrix harder to design but if the components fail because they were conducting electricity I don't see how lowering the current would help them last longer. If an athlon gives off 50+ watts of heat and runs on 3+ volts (argument's sake) how many amps are passing through through it? Understand I'm not saying LCD current levels wouldn't be easier for the EEs to deal with. I just don't think we'll be seeing dead pixels on an OLED monitor for the same reasons one could find a blown fuse on a power supply. 20 years from now people might have to say, "My old monitor is starting to look kinda red." whereas today they might say, "My CRT needs recalibration." or, "My LCD has a stuck pixel." Then again, there's always counterpoint #1.

Footnote: Their biggest advantage won't be just in power consumption if and when they arrive. It will be that they are emmissive, light, durable, capable of high pixel densities with rich color saturation, possibly a wider color gamut, and cheap.

They're transparent enough.....
