Mitsubishi's OLED TV is Huge at 155 Inches
Mitsubishi showcased a 155-inch OLED TV at CEATEC, however the technology could "potentially" offer larger displays.
During CEATEC 2009 in Japan, Mitsubishi whipped out a mega-sized 155-inch Diamond Vision OLED TV, revealing that the new big screen of awesomeness would be ideal for outdoor applications to make advertising more visible and attractive. 
But unlike OLED TV's cranked out by rivals Samsung and Sony, Mitsubishi's new TV consists of hundreds of OLEDs with a 3-mm pitch as pixels. Ultimately, this type of setup could "potentially" create TVs of any size, however there are still problems with the technology that prevents it from being accepted as ideal, especially for advertisers.
As TechRadar points out, LED screens work in the same manner as OLED screens, but apparently OLEDs can output a higher overall resolution perception due to the way that they are arranged. Unfortunately, the typical lifespan of an OLED still remains around 20,000 hours: that's about two and a half years of normal, everyday use.
Still, we'd like to see this visionary 155-inch beast pushed up against our living room wall and hooked up to the Xbox 360, PlayStation 3, or Nintendo Wii. However, Mitsubishi's Nobuo Terazaki, who showcased the upcoming OLED TV, didn't offer any reference to availability or pricing.

Wonder how much power this thing consumes..
2 1/2 years? are they on drugs?
Yeah that 115 inch comment at the beginning of the article really threw me off me.
I bet I would have to win the lottery to buy one of those.
one of these days I'm gonna dress up like a trade show crew member with some friends and carry away a few items. I assume that tv will get tossed in the garbage eventually anyway.

What you don't watch TV 24 hours a day?
Even at 8 hours a day( which is still stretching it assuming you aren't a jobless basement dweller) that's 2500 days, or 6.8 years worth of viewing.
Is it 115 or 155 inches?
2.5*365=912.5
20.000/912.5 = 21.9 hours
who watches tv 21.9 hours a day???
I thought they found away to increase the life cycle to last as long as an LCD....apparently not.
Anyways I look forward to the day when I can buy a 52 inch model that can last for 1,000,000 hours for around $1600...that day will probably be 10 years away.

In Advertising you leave the sign on 24/7. I assume they did some rounding which caused the 2.1 hour difference in your (correct) calculation. You would probably get 4-5 years in stadium use and as others have pointed out, about 6 years in normal household use. I'm still weary buying something I know has a defined lifespan. I could use a B/W CRT from the 1960s and 70s today if I bought the other $9000 in tech needed to convert everything down to it.
Power consumption on this should actually be a lot lower than an LCD or even LED lit LCD display of the same size. That's the beauty of OLED technology...astronomical quality at a fraction of the power cost...and eventually price.
Am I correct in that "lifespan" for tv's is typically the amount of time it takes for the display to be at around half of it's original perceived brightness or brilliance? I know that's how they used to explain plasma life spans years ago.

As long as the old stuff is in good repair, bulbs changed out every so often. The technology will last. I am also weary of buying something that isn't built to last.
It's on youtube "CEATEC: Mitsubishi's OLED has unlimited size"
You can watch it on youtube search "CEATEC: Mitsubishi's OLED has unlimited size"
That's a good argument for existing DLP and projection LCD tv's, since a new bulb brings you near mind-condition picture quality for several hundred bucks. Or are you talking more about older commercial displays or scoreboards where one incandescent light bulb is one pixel? This technology seems more out to replace large LCD type commercial ad panels which can't be restored to their initial quality with a bulb change. I'm willing to bet early LCD commercial ad panels had similarly short projected lifespans when they were first being put into use. Give it 3-4 years, I bet that number will jump to 40,000 hrs, perhaps more.
As for CRT's from the 70's, those hit their factory spec'ed lifespan limits many moons ago if they've been under normal usage. Sure they may turn on and deliver a picture, but I doubt it's near the set's original quality.
Still, 20,000 hours is over six years if used only for 8 hours a day 365 days a year. But I would bet they won't be in our price range for some time...!
For a living room environment 20,000 would equate to over 15 years of life.
20,000 / (365 x 15) = 3.65 hours/day. I'm sure some families watch more than 3.5 hours of TV per day, but I'd say thats a more than reasonable number.
Our home theater projector last us 4 years, the bulb died at 3982 hours, which averaged to around 1000 hours a year, or 2.73 hours a day, and I don't consider us to be 'light' TV watchers.
i would love to game on this screen. in all its glory.
I think they just made a mistake w\ the 2 1/2 years for 20,000 hours.
40 hours per week is 2056 hours per year. 2000x10 is 20,000... so should last a long time.
When I saw the 2 1/2 years I was WTF!? It would be insane if you had to drop $1500-2000+ every 2 1/2 years to buy a new tv.
I've had my first tv, a 50'' DLP i got for $500 on craigslist for over 2 years and it's still working great. It will be the video game tv when we get a new LCD for the living room.
...why do I have to point out the obvious? OLED compounds degrade over time regardless of whether the TV is actually on. So yes, it is just under 2.5 years.
the 2 1/2 year estimate is accurate in the sense that they're marketing this display for commercial advertising. Hence, 24 hours a day, 365 days a year of non-stop usage (8760 hours right there). I have no idea whether or not that's up to snuff for a typical ad in Times Square, but it's cool to know the tech is moving along quickly
I am perfectly ok with 2 1/2 years. By then Ill be ready for a new one anyway. so the porn models will be nearly life size. Now make it 3d and ill be set. muhahaha
oled lifetime is gonna be alot shorter than 20,000 hours.

Nope. They degrade only when on.
Porn in real size! A Dream comes true! What comes next? Maybe I'll find a girlfriend!
...err...
Dude my OLED is bigger than urs....really!
Didn't 10" or somewhere along that size OLED screens cost several thousand dollars only a year ago?
I'm mainly interested into how many pixels they can cram into a 30" screen.
Pixels > Screen size.
I'm surprised to see no one crying about the zune HD using an OLED... seems to be perfectly fine so far >_>

Pixels
Go back and read the article again. They said the dot pitch was around 3 mm. The dot pitch is way too big for the average living room or bedroom. Even a standard definition crt is only around 1-2 mm dot pitch. For high definition viewing, something less than 1 mm dot pitch would be ideal.
