Samsung having trouble with its YOUM flexible display yields, devices put off for H1 2013

Samsung having trouble with its YOUM flexible display yields, devices put off for H1 2013
We've been waiting for a phone with flexible AMOLED from Samsung this year, as that's what all rumors were pointing to, but it seems that the manufacturer has run into road blocks when trying to leverage the lab process to mass scale production, a Korean publication reports.

The decision to make a dedicated A3 line for making the YOUM-branded flexible AMOLEDs has been canned, and the process moved to the existing A2 one for easier supervision. The problems is said to be not with the blue diode, which is produced with the existing FMM method that Samsung makes the Galaxy series AMOLED screens with, but rather with the red and green ones, which have to be produced by the new Laser-Induced Thermal Imaging (LITI) method. 

While LITI allows for much higher pixel densities, and is much cheaper than FMM, it is also hard to scale for a mass production, and apparently that hybrid production method is what Samsung is struggling to sort out now. 

If it manages to figure it out by year-end, high-resolution unbreakable AMOLED screens with RGB pixel matrices and plastic substrate are poised to enter devices in the first half of next year at the earliest. Samsung is the company that broke a football field worth of display glass to make those HD Super AMOLED screens, after all, so we keep our hopes high.

For more information about the advantages a flexible AMOLED display brings, you can read our dedicated interview from the research lab.

Yup. Sucks that apple filed for a patenton the idea of the tech 5 years ago right?

New technology, and highly innovate at that. No real surprises here that it's taking some time to work out, but the wait will be worth it if they can figure out some beneficial real world uses for this. In the meantime, the display on the Note 2 phone is getting great reviews, it's not like we are having to use poor technology until this gets ready for mainstream consumption.

Didn't Apple patent this yesterday? Funny, Apple has a patent with just a doodle and Nokia/Sammy have no patents despite working protos? Funny USPTO. PS:Anyone who'd actually write to them regarding Apple's dumb patents and having an idea if patents like rounded corners/trademarks like App Store can be revoked?

They aren't patenting the tech for the screen they are patenting the use of the tech in a phone that uses it lol. So in other words they are saying they will use the tech in a certain way.. preventing the actual MAKERS of the screen from using it in that way.

I take this opportunity to welcome you to the love affair between Apple, copying, patenting, litigation, USPTO and obvviously the US courts.

Its America they do what they want.. look at their track record.. rectangle rounded corners.. swipe to unlock.. pinch zoom.. scroll bounce.. slowing and speeding up of scrolling.. multitouch.. unified search.. c'mon Its effin stupid. Coming next week Apple patents action of putting in a patent causing everyone who applies for a patent to violate it and be sued.

this just keeps getting worse by the minute we really need to go over the patent system and iron out the loop holes for anti competatative behavior and thank you for the no_nonsense
