40" OLED Television Revealed at SID
deglr6328 writes "Seiko Epson has unveiled a massive 40 inch OLED display prototype at this years Society for Information Display (SID) symposium in Seattle. The display was printed on to a backplane containing the drive electronics with a specialized inkjet process using Phillip's PolyLED technology. Samsung and Phillips also showed large scale OLEDs they say can also be scaled up to 'television sizes.'"
They've still got development to do. 260,000 colours aren't enough!
This is pretty cool, and it's actually one thing my research is tied to. I dunno how long it's gonna take but we're hoping to be able to print these things on a variety of press types, at much faster speeds than inkjet allowing the product to be a lot less expensive.
Right now though it's too costly and inkjet is definitely not ideal for large scale production, but we're definitely headed in the right direction. The biggest issue is finding materials that will work in the product that can be printed. It's a big PITA.
That and how long with the OLED display they've built last? OLEDs don't like oxygen and the damn things will basically decompose. For large expensive displays like that there's still concerns in that area.
Either way, awesome approach, using the different colored nozzles is pretty clever, a lot of the current systems require separate coatings to be applied through various means. It'll still be a lot faster and cheaper down the road when large presses can be used.
Someone here made a calculation, and if we could print at 2000fpm on our Sunday 2000 Heidelberg press, all the displays in the world could be printed in a couple hours. Not like that would be practical or even likely.
Presently here, but not there.

This is photoshopped. The image on the screen is more clear that the detail of the stand it is framed in. The detail of the image on the screen and the fram should be on a par. But they are not.
That is BS. Credit of the photo is samsung themselves, so nobody outside of samsung saw it for real.
I am not saying samsung doesn't have an OLED display, I am just saying that that picture is a crock of PR shit if ever I saw one.
I am hoping I am wrong and we get awesome screens in the future.... but I just can't believe that photo.
You must also be suspicious of me being a samsung astroturfer "I can't believe it".
tinfoil hats abound
As allways in these OLED dicussions the question is: /. brings a story about that, ThEn OLEDs gets really really interesting (as opposed to now: they are 'just' really interesting;)
How long before the display starts to degrade?
In other words: Have they solved the problem with OLEDs that they start degrading after a record holding short time?
