Should you wait for an OLED TV?

OLED TVs

OLED screen depths are measured in millimeters.

Commentary There's a guy over on AVS Forum, Gus738, that we like to mock. OK, maybe not mock, but we always thought his signature tagline -- Waiting for SED -- was amusing in its geeky videophile pretentiousness.

For those who don't know what SED is, it stands for "surface-conduction electron-emitter display," and until a few weeks ago, it was the next big thing in flat-panel TVs. SED enthusiasts are quick to note that it offers all the impressive picture-quality traits of a traditional tube TV, but it's as slim as a plasma. Unfortunately, some next big things don't quite pan out, and it now looks like Mr. Waiting for SED, as we like to call Gus738, is going to be waiting a while longer -- perhaps forever. Alas, Toshiba and Canon became snared in a legal imbroglio over patent disputes with a company called Nano-Proprietary, which put a damper on the commercial development of SED TVs. Toshiba declared that its partner wasn't able to produce SED panels "to the original schedule," while Canon stated the obvious when it observed that, "The prices of flat-panels are declining more rapidly than expected," making it virtually impossible for SED to compete against plasma and LCD.

It was a cruel day for HD aficionados. After a couple of years of teasing us with SED prototypes, we were promised that retail units were tantalising close -- they'd be in stores by year's end, Canon said. LCD and plasma would have a new competitor. And while SED sets would assuredly have been very pricey (rumour had it that a 42-inch model would be in the US$5,000-to-US$8,000 range), those willing to spare no expense for the finest picture quality in a flat-panel display would have had something to throw their money at. Let's not forget that small but vocal group of cynical observers who like to chide today's flat-panel buyers for overpaying for "yesterday's" technology. (These are the same people who like to say holographic discs are on the way, so why bother with Blu-ray or HD DVD).

Sadly, SED wasn't meant to be. So, what do we have to look forward to? What acronym will carry the mantle for flat-panel of the future?

The one that everybody likes to talk about is OLED or Organic Light-Emitting Diode. At this year's Consumer Electronics Show in Vegas, Sony had a pack of them on display at its booth, and they were clearly one of most compelling items at a trade show that was decidedly short on wow factor. Not only is an OLED display incredibly thin (3mm to 9mm), it has a superhigh contrast ratio (allegedly, one-million-to-one), it boasts faster response times than LCD or plasma, it looks incredibly sharp with colours that really pop -- and because OLED screens don't require a backlight, they're more energy efficient than plasma or LCD.

The big problem is that it's currently very hard to make OLED TVs in large sizes; for instance, the largest OLED display Sony had on hand at CES was 27 inches. Also, manufacturers are still experimenting with the display's organic materials to increase the lifespan to the point where OLED panels' lifespan would be competitive to that of plasma's. Lastly, OLED also has its own set of patent issues surrounding it -- Kodak holds a number of patents -- which means manufacturers such as Sony and Samsung will be required to pay a licensing fee for every OLED TV they produce.

After the SED debacle, it's easy to get cynical about the prospects of OLED unseating plasma or LCD as the flat-panel champ any time soon. However, I think that ultimately, while SED had plenty of fanboys like Gus738, its basic problem -- and why it was never going to make it -- was that it didn't have a real advantage over LCD or plasma. By that I mean its picture quality wasn't that much better. The fact of the matter is that, when you looked at an SED prototype next to a plasma or LCD, you didn't immediately declare it the winner -- you actually had to look and think about it. As I said, it looked really good, but at the same time, plasmas and LCD panels have been improving, and in the end, the difference just wasn't that significant. And ultimately, I think, that's the reason Canon and Toshiba abandoned SED.

OLED, on the other hand, holds one key advantage: the panels are much thinner than LCD or plasma. And in a world where flat-panel TVs are looking increasingly alike, with subtle picture-quality difference, companies will be focusing more and more on the design of their TVs.

To a certain degree, Sharp executives said exactly that at a recent press luncheon I attended in New York. With 1080p gradually becoming more of a standard feature on HDTVs (flat-panel and rear-projection sets), it becomes harder and harder to set TVs apart from a features standpoint (you might call it features saturation). For instance, Sharp -- and other manufacturers -- are touting 120Hz refresh rates in their new LCDs. The faster refresh rate is supposed to help eliminate motion blur, one of the knocks against LCD. But once LCD manufacturers get beyond the motion-blur issue and continue to improve black levels, the feature improvements will become very incremental, and there will be an increased focus on design.

Sharp execs said they were keeping an eye on OLED. They're not terribly worried yet, particularly because of OLED's current size constraints. But if Sony is able to put out an OLED model this year as it's now promising (it's only an 11-inch display, but to get anything out on the market would be an achievement -- even if it's ridiculously expensive), their concern might rise a touch.

The long and short of it is, if you're waiting for something better than LCD or plasma to come along, chances are you're going to have to wait a long time. OLED appears to have a lot of promise, but I don't expect to see an affordable 42-inch model for another five to six years. It's possible that smaller OLED displays (20 inches or less) will become options for kitchens, bedrooms, and bathrooms in somewhere closer to three years, but like SED, the technology might never pan out -- or make sense economically.

That said, true diehards like Gus738 seem intent on holding out and sticking with their current sets. As he said in a recent post, "Well, all in all, I hope OLED makes it [...] cuz I want a better TV then the current pos LCD/PDPs.... So far my CRT tube is making it...." I would humbly suggest, however, that he change his tagline from Waiting to SED to Waiting for OLED. Just a thought.

The article was written on 2007.

Now it's 2010.

Where is my OLED TV?

And please, stop asking me to be patience.

OLED's will take over the market.. LCD and PLASMA's will die very quickly when OLED's hit shelves

OLED's already hitting the mobile market.looks like will be in the tvs anytime soon.

yeah chris i remember hearing big things about laser tv's awhile back, ment to be cheaper thiner and better picture quality than plasma and LCD. whatever happend to that?

not impressed with LED lights believe they are expensive to replace , have a LED torch 1 yr old , now no good .
Want better value 4 my money , a Tv which lasts 5 yrs at least no major expenses .

I am amused by david carnoys comments re SED, how did he come to make a statement that SED is dead?
if he bothed to do any research at all
he would have discovered that CANON
have lodged an appeal against the original texas cowboy judge's ruling,
you do not bother doing that if the
product is DEAD! as to the new
120hz frame rates for LCD, you will notice in all the company's claims
that this only REDUCES motion blur
it does not eliminate the problem,
next time you see a SONY blu-ray
demo on their bravia LCD sets, notice
that there is never any high speed
action shown, except by accident
with the colored balls being ejected at
great velocity from a shute down a hill
in San Francisco, if you look at the side
on shot, you will notice the elongated
ball structure of each ball, thats
equivalent to four ball diameters,
even their latest model 100hz motion
flow sets cannot overcome this
refresh rate problem, SED does not
suffer from this, the balls will maintain
their spheroid shape at all times,
thats only one of the reasons CANON
is proceeding with SED, another reason
is contrast, and the degrees of black
level, remember while all this court
action has been taking place SED
developement has continued unabated
with some big breakthroughs in
reduced cost of manufacture, as well as further improvements to performance,
just because you have not heard any
thing since the appeal was launched
does not mean SED IS dead

I sell Plasma's and LCD's at a retail level and like I say to my customers "if you're waiting for the next generation you may as well measure up for your coffin". Get a life buy whatever you can afford and buy it now, after all you can always sell it when something new does finally come along. Isn't that what we do with cars?
I get sick to death of people getting paranoid about a few grand when the cars are 40 grand.Geta life you folks.
Especially GUS738

OLED is coming, Samsung have developed a 40" prototype and it leaves plasma and lcd for dead. I own 2 plasmas and 2 lcds, once OLED comes out I will own 4 OLED displays.
