Samsung shows off OLED display collection at CES

OLED displays were out in full force this year, with Samsung bringing plenty of its own to showcase to CES onlookers. We already had a chance to check out a snazzy folding OLED late last week, but CNET was able to capture a few more for good measure. The most notable were the 3.3-inch "3D" AMOLED display (with a WQVGA resolution) and the 7.01-inch AMOLED panel, which was seen sporting a 1,024 x 600 resolution and a 30,000:1 contrast ratio. Flip through the gallery below for a few more looks, but don't get your hopes up too high for any near-term release dates.

A 3.3" 3D display? Weren't the big ones already headache-inducing enough?

So... how long until these get big enough to actually replace my TV? I saw one in a Sony store and I was amazed, I want one. I would like one a little larger than 11" though.

15" LG is coming this year.
2010-2011 is when to expect lots of OLED TVs, those were the numbers "analytics" gave us.

All depends on overcoming technological hurdles I expect, and overcoming those is a matter of luck and some guy thinking up a good fix, which could take days or years or decades (although in that case other technologies will have taken the place of OLED).
I'm not sure what the hurdles are though, but it can't be some weird coincidence that nobody can make large ones, not even for bragging rights.

I don't see any comments that says, '"Oh my God!" They just stole sony's idea of the OLED!' Oh wait, that's only if they copy Apple's. Right.

What doo you mean by "stole Sonys idea of the OLED"? The OLEd wasn't invented by Sony. It is over 50 years old now and goes back somewaht to A. Bernanose and co-workers at Université de Nancy in France when they first produced electroluminescence in organic materials in the early 1950's.

The hurdles are that the organic molecules to produce the color blue arent verry stable. They only had a lifetime of 14000 hours (running 8 hours a day), where current LCD's and Plsama-TV's had approx arround 60000. Different ideas and ways for solving sprung up like coating with fish-oil (substract made form the oil of salmon that stabelized the degradation of the molecules by some rate) and others.
Some of them produce now lifespans past that ones of LCD's (current experimental fifespans for color red >9000000 hours, green 198000 hours, blue 62000 hours). Also the lifespan here isn't the actual lifespan of operation till a diod dies off completely, it's more a calculated lifespan till to the point where the diod only produces 50% of her initial light output, quite noticeable. It also is depending on the operation temperature and the light output you draw (a well cooled OLEd with a short lifespan is still better off than the same run on higher temperatures and one run on 80% lightoutput lasts in average longer than one on 100%). So if your read somewhere, that the red OLED's last in average 10Mio hours, ~1100 year, it is only a statistic average. There might still die a few within the next 5 years. And statistically a few in short time for blue is noticeable in pixel failures.
The lifespan is important for high end consumer electronics such as TV's and computer displays, as you can imagine. It's far less importend fpor portable devices withe smaller displays such as cell phones, mp3-players and car radios for they usually get replaced befor the displays decays and also dead pixels arent't that relevant where as on a screen your work with or you watch movies it's quite enoying.

Add:
because of the decaying of the organic molecules, especially the less stable blue ones (they are all verry sensitive to oxigen because organic material is oxidized easily), it is one off the first logic necessities to seal the display off airtight.
Sealing off a small panel is quite easy but the bigger ones... You need a whole anoxic production-lines for compley large displays with complex active matrix backplanes in which the whole panel is produced. And the bigger the surface, the greater the margin for errors and the more severe the consequences on a failure = a whole 40" panel might be rubbish, time and money down the drain, where you can produce with ease 1000 small displays and only loose a few.

Add2:
As I mentioned, the hurdles lay mainly in the life expectancy of the blue coloured units. They had a seriously decreased lifespan compared to the other colours in the display. However this has been improved on recently.

Other problems included the organic LED’s distaste for water. Any water that is introduced to the display would destroy the unit. So you also need to make the diplays waterproove and no water must be introduced or even present in the slightest during the production process.

Due to the high output of the green element in OLED displays, OLED screens are often green biased unless appropriate limiting actions are taken.
