back to article Flexible Willow glass displays thin and curvy gadget future

Corning has been showing off a new form of flexible glass that is the thickness of a sheet of paper yet easy to mass-produce. Dubbed Willow glass, the material can be manufactured to just 0.05mm thickness compared to current 0.2mm or 0.5mm screens, and is suitable for touch control systems and with LCD and OLED displays. The …

"Add slimness".

Are they going to simplificate and add more lightness too?

yeesh. :)

Re: adding lightness

According to the article, they're going to _drive_ the weight out. They''l beat it with a stick, have an intervention and get an exorcist if they have to, but they'll _driiiiive_ the weight out and command it never to return!

Oh come on.

It could just as easily have come from trick photography and bullshit.

Re: << See icon

I'm guessing (and it's a WAG, for sure) that the quote is merely to imply that Corning is NOT employing Glass Fairies with magic wands to make the glass so thin and flexible. At least, not for this particular glass. But I could be very, very wrong about that - it could be pixie dust doing it, for sure.

Imagine the optical devices you could make with this...

If they could make it even weakly piezoelectric, it could be beyond amazing.

marketing crap

iLet hope there technology is better then there marketing department who are clearly full of crap and manage to say nothing and show nothing in a generic roller video. I don't want a slimmer phone, I want more space for a bigger battery!

Re: marketing crap

I prefered the term 'ribbon glass', that's what they called it twenty odd years ago on the Tomorrows World tv show.

He is not doing the Grammar salute.

That icon is clearly unsuited for the task at hand!

Now I will quietly retreat to a dark corner in order to adequately contemplate my own failure in being properly versed in El Reg's canon of visual aids.

Paris, coz shes haz teh smartz jus liek meh.

"better then there marketing department"

If you're going to be a Grammar Nazi (which I wholeheartedly approve of) at least finish the job.

I'll leave it as an exercise to you to find the other error.

Thumb Up

Vidoe long on pretty, short on information.

BTW the "spilling out of a trough" is basically the Pilkington process where the glass floats on molten tin.

However the equilibrium thickness for this is set by surface tension and density of the glass and the tin to around IIRC 7mm, but surface quality is excellent. The *thinning* process that Corning have developed sounds amazing.

Note You know have a substrate that can take 500c process temperatures without damage which is also transparent.

This *could* open up lots of more speculative ideas (if the price is right) which have been handicapped because some of the other pieces need high temperature process that existing substrates would be destroyed by.

Thumbs up for some clever engineering.

I would have thought that most combinations of steel and modern ceramics would be good to beyond 500 C. for industrial processes, provided the temperature change rate was controlled...... ?

"I would have thought that most combinations of steel and modern ceramics would be good to beyond 500 C"

And how many of those substrates are routinely transparent?

"capable of producing sheets a meter across"

Please don't let Samsung hear about this or we'll need wheelbarrows for our phones!

Well, that explains everything

Flexibility

Surely the flexibility comes from it's thin-ness, similar to glass fibres.

More marketing bullshit?

Old news.

Isn't this the same thin flexible glass that was going to revolutionise everything about 20 years ago? I'm still waiting for my motorcycle visor with 0.1mm glass glued on it.

question

I wonder, if you flatten it bent over does is fracture or crease (like plastic)?

I further wonder what the smallest diameter bend that can be achieved is, and how many flexes before it fractures/creases.

I even further wonder if I should hold onto my iPhone 3G for just one more year to get next years phone with roll out screen?!

Re: question

iPhones won't have roll-out screens because fortunately Samsung beat Apple to the flexible-screen patent, and given Apple's recent patent megalomania, I don't think Samsung are likely to share. Which IMO serves Apple right.

I see someone holding a bit of bendy perspex and an animation of some rollers.

It all seems like lies to me.

Oops. Corning *do* have their own glass process

It works by filling a trough (or "isopipe" as they call it) which has a triangular cross section tapering to a point at the bottom. When over filled the contents form a sheet dripping down each side. The sheets merge to give the final result.

The key benefit is that the inner and outer faces of the new sheet have *never* been in contact with anything (even Tin) and their smoothness can be very good and the sheet can be stretched further.

Some of their patents suggest the isopipe is machined out of Silcon Nitride or Carbide (which needs to made in a low Oxygen environment) then surface oxidized to form a silica outer layer to reduce contamination even further.

It's not very well explained in the article and I'd never heard of it *ever* before. Apparently it was developed in the late 60s to make car windscreens. Other than not being the Pilkington process I'm not sure what benefits it would have bought to that application.

My bad
