Epson OLED Prototype  (Source: Akihabara News)
New process paves way for 37-inch and larger OLED TVs

One of the most promising screen technologies currently being developed is OLED technology. OLEDs have the potential to offer better screens for all sorts of products from lighting, to windows and consumer electronics.

Seiko Epson Corporation has announced a breakthrough technology that uses inkjet technology to uniformly deposit organic material for the production of OLED TVs in large screen sizes. The company says that the breakthrough is a major step in developing 37-inch and larger OLED TVs with full HD resolution.

Many are looking to OLED HDTVs to replace plasma and LCD technologies. The main reason for this is that OLED screens offer high contrast ratios, better viewing angles, and fast response times to eliminate ghosting and image quality issues. OLED screens also need less power than comparably sized plasma and LCD screens making them more environmentally friendly.

Current OLED construction methods using vacuum thermal evaporation technology has a technical limitation that prevents it from being used to create large screen OLED TVs. The Epson breakthrough uses a proprietary Micro Piezo inkjet technology to achieve a much greater accuracy in organic material deposition than current technology. The layers produced using the technology are very uniform with less than 1% volume error.

"Large-screen OLED TVs are the future of displays, and Epson is committed to contributing to the transition to volume production through research and development projects involving inkjet fabrication technologies," stated Satoru Miyashita, General Manager of Epson's OLED Development Center."

Epson says that more details about the new construction method will be presented at SID 2009 on June 2 in San Antonio Texas. The company will also show a 14-inch prototype OLED TV with HD resolution built using the process.

Chinese natives usually have trouble pronouncing English v's. Accents are funny, like in Fargo and the Squishy guy in the Simpsons. Know what else is funny? The name Terd Ferguson. It's a funny name. And big hats. Because they're bigger than a normal hat.

I'm Chinese. I didn't find it offensive because his aims weren't too make fun of the Chinese but to make fun of inkjet technology in general.

Let's face it, ink cartridges costs more than blood. Heck, I haven't seen the latest comparisons but it probably costs more than its weight in gold. That combined with the many Chinese philosophers made that person create a fake proverb.

It's like the "In Soviet Russia..." or people in the USA making fun of Canadians. It's not meant to be racist or hating on another countries populace. It's just a joke.

Heck, while on vacation in Hawaii, I had a Canadian curse about the "damned Americans" never realizing he was an American. He lives in the frickin continent known as North America. He's also vacationing in USA soil. Should I take that personally as well being a citizen of the USA? No, just get over it and move on.

If we took everything too seriously, we'd have never ending war and strife. Example: the Middle East. As far as bias against Chinese goes, there are plenty of things to get upset about but I find this one not even registering a blip on the radar.

While I agree with much of what you wrote, typically a Canadian is not considered an American because the term does not usually mean one who lives on the north american continent, it means a citizen of the United States of America. That's what he meant, you understood that is what he meant, this is what language is, using terms as they are commonly held by those speaking the language.

I guess it depends on who you ask. I was born in the USA, and consider myself 'American', but my wife, who is from Brazil, also considers herself 'American'. She's not right here to consult, but I believe she calls people like me norte-americanos.

Of course some Chinese would find this offensive even though it's a common joke in the west,But it's called freedom of speech!
Don't tell me Chinese never bag others outside their country,It's human nature wether you like it or not,Lighten up. Uptight people like that cause wars,death and destruction or end up in prison because they can't control simple emotions.
I'm an Aussie an we bag the crap out of everything and anyone,even our own. But that's why we are so easy going,Cause we can give and take a joke!

For at least 8 years now, at least since I saw a Japanese infomercial in 2001, explaining how some special fluorescent shellfish emitted different colors of light, RGB. They showed that it would be possible in years ahead to exactly paint it on, which will open up for cars acting as big screens, cloaking devices etc. In the same video they showed a fold able 12" color panel.

Finally it's getting there!


"Ink Jet" printed screens -- higher densities?

Does this mean we can finally get screens with 600+ pixels per inch someday? Maybe we can finally move to a paperless world after all!

The human eye cannot discern the difference between 720p and 1080p on a 42" TV at 6 feet. So a 600dpi screen? You'd probably have to be within 12 inches.

My eyes are inhuman then. I traded my glasses for Lasik surgery several years ago, and have 20/10 vision now. From six feet, I see pixels on my 42".


By AnnihilatorX on 5/26/2009 6:18:26 PM , Rating: 3
20/10 vision is twice better than normal eyesight. So it's equivalent to a normal person seeing the 42" in 3 feet.


By mindless1 on 5/26/2009 8:52:17 PM , Rating: 2
Not necessarily, your field of vision increases while the number of receptors in your eye are the same. Take a vision chart for example, the person is not discriminating at the pixel level, only shapes, and it takes longer to discriminate the smaller characters which are static instead of potentially changing at 24+ FPS.

But the human eye can see objects as small as 50 microns.

At a distance color/light-'bloom' probably masks some of the precision, but if the screen is 100% sharp with no bleeding between pixels, the pixels have to be very small to 'disappear'.


By mindless1 on 5/28/2009 9:47:16 AM , Rating: 2
Seeing an object and discriminating it from another different 50 micron object, at a distance, is not the same thing. Now consider stacking a pattern of these 50 micron objects right next to each other and trying to discern if you see 48 together or 47.

Most people view paper (or hopefully someday ePaper) at about 15-30 inches so 600dpi is not unreasonable. It is reasonable to say that it is difficult to tell the difference between 600dpi and 1200dpi when it comes to printing technology.

But even if you cannot discern the dots at 1200dpi you may still sense an improved image compared with 600dpi so I would say ePaper manufacturers should probably strive for 1200dpi=50dpm which is about 13x better than a typical LCD/CRT.

OLED lifespan was, until recently, roughly 3:5 the lifespan of LCD. IOW, about 30,000 vs 50,000 hours. Last year Panasonic and some other company made some breakthroughs that may be pushing close to 70,000 hours by now BUT that was with their tech, not necessarily something compatible with Seiko's tech being announced today.

Here's an OLED TV tested last year that had a significant degradation after only 1000 hours so I would take the above 30,000 hour and more lifespan with a grain of salt, what they can theoretically do doesn't necessarily end up in the TV on the store shelf.


only a matter of time

The same technology (inkjet "stamping") has been used for over a decade now for DNA microarray analysis.

I'm hoping that the application of this towards the entertainment industry will further drive development of the technique and drop costs for the process in all fields.

This is super cool stuff.

It's also used by First Solar to produce their cheap photo voltaic panels. And I think it's used in some other silicon chip manufacturing as well.

I've never seen a Seiko-Epson TV. No doubt they will be licensing the technology to TV manufacturers. Might be a good time to buy some stock. However, don't expect a quick return...

Seiko Epson has made an advance in ink-jet technology that could be used to mass-produce large OLED (organic LED) screens by the middle of the next decade,....

I wonder how's the picture quality for SD materials. Plasma is still good for SD broadcast, however, LCD magnifies the 'flaws'. Then what will OLEDs do?

Display technology has nothing to do with the filters going on after a decoded video. All it does is display it.

You question is akin to my mother asking me if getting a new mouse would make the internet faster.

Sooner or later, it will happen. OLEDs will be cheap and used everywhere.
OLED-covered wallpapers for your house - initially without separate-pixel level controls but just all-on/all-off, used for lighting instead of light bulbs. But eventually even working as a TV. You can have a literal "video wall". Or six, floor and ceiling too, for a virtual reality cube room.

Too bad that none of the big corporations would actually consider such cheap OLED availability as a good thing for their business... so it will probably be much later rather than sooner.
But it will happen.
