Inside LG's 6" flexible display: largest phone OLED panel will bring feathery devices

Inside LG's 6
We don't know yet the exact curved panel specs of what Samsung will eventually be revealing later this week under the Galaxy Round trademark, but LG already showed its cards, announcing the world's first 6" flexible OLED display for commercial smartphone usage.

The company just sent us its details, and the specs are indeed breathtaking, who said that after 1080p mobile displays we couldn't get much more innovation in the field?

First off, the panel is made with a plastic, instead of a rigid glass substrate, meaning it is much less prone to braking, and can bend over backwards, literally. LG says it is concave from top to bottom, with 700mm radius, which opens a plethora of possibilities for phone designers in the first place. Not only that, but, as researcher Michael G. Helander, a PhD Candidate at the University of Toronto, advised us in our interview with him:

One of the big advantages of moving to flexible plastic substrates is not the flexible form factor, but rather that the displays can be made physically thinner. Currently, one of the bulkiest parts of a mobile display is the glass substrate itself. Note that the glass substrate the display is built on is different than the front glass on our cellphones. Typically, the display is fabricated separately and then glued to the front glass plate. The glass used to fabricate the display has to be thick enough to structurally support the display without cracking. Below a critical thickness the glass is just far too fragile to be effective, particularly with the ever-increasing size of mobile displays. The trick is to fabricate the AMOLED display on thin flexible plastic, and then laminate it to the front glass plate of the mobile device, typically made of Corning’s Gorilla Glass.

LG's flexible display panel official specification confirm what Michael is saying above, as the 6" screen package is just 0.44mm thin, and, since it is built with plastic instead of glass, it is also incredibly light at only 7.2g for the whole thing. These specs would be record for a mobile display, if it wasn't for Samsung announcing its 5.7" bendable OLED minutes after LG, and theirs is just 0.12mm thin, and 5.2g light. Bummer, but we should note that what LG unveiled is also the largest phone OLED screen produced, with the closest being the 5.7" screen on the Note 3, so LG still gets to keep that record.

LG doesn't mention other important aspects of the first 6" flexible display panel for mobile phones announced, such as resolution or brightness, so these might be nothing to write home about yet. What's most important, though, is the fact that this bendable OLED tech will allow for amazingly thin and light handset, which would on top of that be extra durable, compared to the current crop. 

Yields might not be enough at first, at both Samsung and LG, but we can't wait to see the first birds of the flexible display phones spring - LG G Flex and Samsung Galaxy Round - to gauge what's in it for us in the not so distant future. The G Flex is expected next month, whereas the Galaxy Round should be unveiled as soon as this week.

Cant post URLs friend.. My account has to be 7 days old atleast..

But it wil come with a 13MP cam most probably the same as of G2 and Video BitRate of 20MB/s..

Another LG shill in phonearena.

Phonearena has become a marketing ground for LG.

They say LG has the 'record' for largest OLED screen, but they forget to mention that LG's solution is more than 3x thicker and weighs more.

As usual LG marketing in PA is obvious.

"displays can be made physically thinner"
So this is the main reason behind flexible displays, now we will be able to see much thinner phones in recent future.

Phones can already be made so thin that they're uncomfortable to hold. Thinner displays can play a much more important role -- namely, finally allow room for batteries large enough to ensure a full day's worth of charge is the bare minimum.

Yes, you're right and also it'll allow other upcoming hardware technologies to reside inside and also makes the phone lighter.

LG and Samsung didnt mention anything about scratch resistance??
they are less prone to braking and how about scratching??

How about Stereo speakers integrated in these types of displays?

with all these new technologies, we are still using lithium-ion batteries, which was used on cellphones 10 years ago. someone that comes up with a better technology batteries that can last a week will rack major cash in this line of business.

That'll be next years new tech.

It is hard to come up with new battery technology. And even if somebody does and few people already did (illinois university, the girl who won LG contest), their ideas are swept under the carpet. Where are those technology? They are a big threat for oil companies. Phone that could last a week on one charge is just too much, imagine that power used in cars. Some ragheads could really lose a lot of money if strong batteries were to be implemented into cars. So that's the reason too and they know and we know it too.

so you're telling me that this display will have the same specs as my LG G 2
