Cheaper, easier to make flexible OLED displays might hit the shelves by the end of 2014
We've reported about bendable displays numerous times before. One of the most prominent and notable appearances of the extravagant technology in the past few years took place in early 2013, when Samsung showcased its home-made flexible YOUM display. LG also jumped on the flexible display bandwagon a little later, but this endeavor proved to be quite a hard undertaking for both Korean tech giants. We have not seen a device with a truly flexible display just yet, but this process might hasten thanks to Kateeva, a startup that has developed a manufacturing method, which is capable of producing more durable flexible displays on the cheap.

The company in question, Kateeva, has developed an innovative printing process, which “sprays” a protective layer and encapsulates the OLED units of the flexible display. This coating protects the organic diodes from both of their archenemies, oxygen and water. The inability to develop such an encapsulation method allegedly prevented Samsung, the smartphone maker that still reigns supreme, from manufacturing its YOUM displays on a large scale. The Galaxy Note 4 was rumored to sport a flexible display, but this is not among the most probable speculations regarding the upcoming phablet.

“Just a few molecules of oxygen or moisture can kill the display,” claimed Greg Raupp, an Arizona State University display expert. “So the encapsulation requirements for an OLED display are quite significant.”

Another issue that needed to be solved was the implementation of transparent ITO (indium tin oxide) electrodes, which are used in touchscreen displays. These electrodes are miniature and transparent, but quite fragile – they would easily break if you bend the display. Fortunately, another company, named Canatu, has found a way to solve the problem – it ditches ITO electrodes for carbon nanotubes, which are not only more conductive than indium tin oxide ones, but also survive stretching, flexing, and bending quite well.

So, bring it on, smartphone industry!

Samsung's mobile enterprise always have and use cheap dustbin junk plastic materials. If you look at their other products, it uses quality prestige materials.

Another cheap bendable plastic.

Throw that in the bin, and start using Dragontrail or Sapphire.

You have to say something all the time. You know sometimes you need to STFU.

Do you like plastic widows?

Does the car you drive have plastic windows?

Glass is better and feels and looks premium than cheap plastic.

And you know some part of sports cars and space rockets are made from plastic (special one).

More like carbon fibre.

Forgot to mention, do you have plastic coffee table instead of Italian fine prestige made glass coffee table in your house?

We are talking here about flexible oled evolution. And you talk about plastic?!

It's using plastic to blend in.

On my boat the table is made by plastic and on my house is from steel/wood/glass. But with my boat I am moving on. And the only moving house is made by plastic.

This is what Ive been waiting for. Samsung knows how to push technology. Never rush buying a phone every year.

Yeah a bendable display, but a brittle glass coating /layering on top.
makes perfect sense

That's quality. Or coating with Dragontrail.

Hey let me ask you something if someone was gonna shoot you and you had the option to grab a sheet of normal glass or a sheet of plexiglas (made of plastic) which would you grab to protect yourself? glass is heated sand once you start adding chemicals or changing the manufacturing process it stopps being glass, so stop your premium argument and think about this if it wasnt for samsung making all this stuff you wouldnt even have a smartphone considering samsung made 80% of the parts in the og iphone

That's a different case. This is an item to be seen and touched and feel. Not something that you wear.

What are you talking about i was refering to a sheet of plexiglas not some clothes, in government Buildings they use plexiglas because it is bulletproof and you see those every day in court houses, police stations etc, they are touched and felt everyday by someone or something so how does that make it a different case?
