TMD Develops the World's Largest OLED Display

Toshiba Matsushita Display (TMD) has developed the world's largest 20.8-inch low-temperature poly-silicon (LTPS) organic light-emitting diode (OLED) display panel to advance to the next-generation of flat-screen TV sets and monitors. The new 20.8-inch OLED display has been developed based on LTPS technology, which TMD has been continually refining, and an electroluminescent coating process, which is advantageous for larger display screen sizes. The three (RGB) color-emitting layers use polymer organic electroluminescent materials, and an ink-jet type coating process is adopted for coating of each color. These have contributed to achieving a large screen size of 20.8-inch and would enable the expansion of potential applications of large-size OLED panels, which have been conventionally limited to smaller size screens. The newly developed panel will be exhibited in TMD's booth at the 3rd International FPD Expo (Display 2007) at Tokyo Big Sight from April 11 through April 13, 2007.

hmm... even though OLEDs are very vivid, I dont like it how its sorta pixelated.

One day, these will be available to consumers. By then, the technology will be so outdated, it will be replaced by newer and better products, due to the delays. The only OLED stuff I've seen so far are on cellphones, and some MP3 music players, maybe that's all they will be used for if they aren't cost effective and easily manufactured.

Such a shame as it has so much potential.

Don't be so short-sighted... You are getting a glimpse of the future. Here's more:

But.. still ain't quite ready for prime-time yet, they've made break-throughs on the blue lifespan, but still needs improvement. And there are so many manufacturing techniques, I think their still trying to pick the best ones to run with.

I still reckon they're way off in producing a commercially available unit. Sure, producing one-offs for trade shows are fine, but one that someone can buy and take home, way off.

Another technology that may be cheaper and easier to produce than OLED displays, are the hybrid LCD with LED backlighting. This technology offers the best of both worlds with LCD's and each pixel having it's own backlight LED, which help produce very high contrast ratios which are close to that of Plasma displays.

OLED as a viable flat panel display technology may have missed the boat.

I think the boat is definitely late... Keep in mind there are things that OLED can do that LCD will never be able to do, but in the meantime, LCD technology is certianly not floundering.

Only time will tell when we see the goods. I'm still shopping for an LCD tv :)

I've got a 40" LCD (two in fact), and want to get a 50" HD Plasma. I've been waiting and hoping to see something come of OLED technology by now, but unforunately nothing as of yet. :(

I just cant see giving up my lcd for oled. If they costed the same and the OLED had as many HDMI inputs (Id like 4 myself) then maybe...but Ill wait till later to make a commitment.

Plasma has burn-in, so not for me.

Does OLED?

Also I heard that these have a short lifetime, is it true?

Yes it appears that way, but over a long time period... it has been a major hurdle of OLED - the lifespan of the blue color OLED. They were only able to get something like a 3,000 hour life until two years ago. They have supposedly gotten over the 50,000 hour mark now.

Keep in mind that there are 6,360 consecutive hours in a year.

And I don't know how they define "lifespan" (if it's half-life or what?)

ZalmannThis is what I think will be the mainstream successor to LCD and Plasma. OLED may have missed the boat. forums.techpowerup.com/showthread.php?t=29163
Ummm... that is LED, just with improved backlighting.

This sure is pretty: Sony 1,000,000:1 Contrast 27" OLED Oh and it's 1080p!!!

It is LED Backlighting. The each LED element is used to light up each individual pixel.

Typo - yes, I meant it is still LCD, but with a new type of backlighting (LED). There wasn't any mention of each pixel being lit by individual LEDs - that would be a rather staggering amount of LEDs, but an interesting idea (Hmmm...)

OLED displays are actually just that - in essence, each pixel is a colored LED.

With LCD with LED backlight, each LED is white. The great thing is it gives more colour scaling as each LED backlit pixel can be fully on, fully off, or a number of gradients in between. Far superior to normal LCD that uses a fluro backlight.
