New Sony OLED Display Can Roll Into Cylinder

StoneLion posted more than 3 years ago | from the still-can't-spindle-or-mutilate dept.

Displays 73

Anarki2004 writes "Sony recently debuted its latest in OLED technology: a 4.1-inch screen that's only 80 microns thick. The super-flexible display can roll up into a cylinder just 4mm in diameter while still showing moving images at 432×240 resolution. Instead of brittle integrated circuit chips, the screen has an on-panel gate-driven circuit — a world first, according to Sony. That innovation would allow everything but the power supply to roll and flex in applications."

Everything but the power supply ... (5, Funny)

Good thing, too - you wouldn't want to roll up the power supply, shove it in your pocket, and have it burst into flames. After all, "It's a SONY!"

frozentier (1542099) | more than 3 years ago | (#32408296)

I'm working on a portable power supply right now. I'm going to call it a "battery".

Re:Everything but the power supply ... (1)

tomhudson (43916) | more than 3 years ago | (#32408880)

... and if you make it round, you can wrap the screen around it ... Quick, patent round batteries! Oh, wait a sec ...

What the heck, do it anyway - the USPTO doesn't give a **** about prior art - they're like Mikey, they'll eat anything you stick in front of them! After all, they patented the comb-over.

My friend told me about this device that powered things without a battery, all you had to do was turn a handle. I thought to myself, that's got to be some sort of wind up.

Re:Everything but the power supply ... (1)

OeLeWaPpErKe (412765) | more than 3 years ago | (#32410414)

Yeah but the problem is that while they could make circuits in the screen, they certainly can't duplicate chipmaking control, efficiency and accuracy on the flexible substrate. So yes, you could have your next phone rollable, if you would accept a 6 Mhz cpu with 2 Mb ram.

Dude, you ruined my day (4, Funny)

Moraelin (679338) | more than 3 years ago | (#32408588)

Bah, just when I was thinking that if it's this thin and flexible, they could put it on a condom and give you the choice of what to display on it (like, say, a $100 bill or a credit card for wives who won't touch anything else of their husband's)... you just have to come and give me the mental image of it bursting into flames.

So the real remaining job (2, Interesting)

fustakrakich (1673220) | more than 3 years ago | (#32407746)

is to make flexible/foldable power supplies..

Re:So the real remaining job (1)

spazdor (902907) | more than 3 years ago | (#32408034)

I think power technology is gonna be the easy part here. Big thick (think fancy home-audio ribbon cables) copper ring around the outer perimeter of the device, with 50 or 100 turns of spiral around the outside. Suddenly every movement through the device's Z-axis generates magnetic flux. Mobile devices might self-charge if they consume little enough and the EM environment is noisy enough. The recharging 'docking station' could just be a little induction coil that you leave the device on top of or near.

As for actual on-device power storage, I think that embedding capacitors onto a layered, laminar surface is gonna be trivial. Most capacitors just are layered laminar surfaces. For higher-capacity chemical power storage, though, you're gonna have to go "off-sheet."

No doubt. As momentarily cool as thin OLEDs are, I can honestly say I would rather not have this tech than have SONY in the marketplace.

Re:Until... (3, Funny)

oldspewey (1303305) | more than 3 years ago | (#32409720)

I don't think they'll disable the feature entirely, but they'll probably require you to buy some kind of expensive, proprietary cylinder that you wrap the screen around.

That's nice and all (2, Insightful)

NotSoHeavyD3 (1400425) | more than 3 years ago | (#32407768)

But when are they going to be able to make 40" TV's that are affordable with OLED? (Hell, I thought a few years ago the shtick was that they could print them out so cheaply you would just make a new OLED every so often if anything went wrong with the screen.)

Re:those stripes (5, Informative)

illumastorm (172101) | more than 3 years ago | (#32407812)

Those stripes are probably an artifact from the screen being rolled up. That should be ironed out if/when the screen goes into production.

So long as you don't have to iron out the screen after you roll it up.

Re:those stripes (3, Insightful)

Anonymous Coward | more than 3 years ago | (#32408634)

I saw similar stripes in early HD displays and then in early OLED displays when i would see prototype footage. I think it's more likely that they are minor problems with the way the screen lights up pixels on a grid. And it should certainly be fixed before production.

Re:those stripes (1)

lowestuid (1767958) | more than 3 years ago | (#32416414)

I have a hard time accepting the claim "it can be rolled around" when it clearly damaged the display doing that. Most of the stripes showed up AFTER they rolled it a couple times.

Dual screen (3, Insightful)

The Living Fractal (162153) | more than 3 years ago | (#32407940)

OK so I imagine that the technology doesn't really fit well with touchscreen designs. That's fine though: I want a device like the HTC Evo with a nice sized touchscreen in the portrait orientation but a roll-out OLED in the landscape which would become a widescreen for video. I'm thinking like 3.5" normal 'portrait' screen and a 8" roll-out widescreen... if they can figure out a way to keep it pretty sturdy when rolled out. That'll be a challenge IMHO.

Re:Dual screen (1)

mdielmann (514750) | more than 3 years ago | (#32408370)

if they can figure out a way to keep it pretty sturdy when rolled out. That'll be a challenge IMHO.

Not much of a challenge at all. I can think of three ways, with varying costs, weights, and effectiveness. I'm sure the engineers involved will do better.

Re:Dual screen (1)

The Living Fractal (162153) | more than 3 years ago | (#32410816)

Really? I can't think of many. The length of the screen would prohibit the use of simple rails that slide out of the body of the phone... they'd be much longer than the phone's width. I imagine that some kind of one-way-bendable rail that can roll up with the screen could work but that would be a pretty delicate thing and if you tweaked it at all you might be pretty pissed when your screen doesn't roll back up..

Three off the top of my head:

  2. something like a folding ruler or cane?
  3. something like a tazer AGGGGHHHHHHHHH!!!!

DigitalCrackPipe (626884) | more than 3 years ago | (#32421400)

I was wondering if I was the only one who remembers (or will admit to having watched) Earth Final Conflict. The only good thing that really came from that show was the communication devices - they pulled the screen from a cellphone sized object to make a reasonably large full-video screen (like pull-down blinds).

The power supply doesn't need to by flexible to solve the old problem of balancing phone/device screen size with overall size when you're not using it.

You think slashdot would put a "primary_link" field into the database to try to wed out duplicate entries. Put in an entry, if the primary link has the same URL as another article with a primary link then they'd get a warning showing them of possible duplicates...

Re:"theater in the round" ? (2, Interesting)

Miseph (979059) | more than 3 years ago | (#32408340)

Hmmm... that gives me a neat idea for and IMAX film... stage a play in the round, with the audience semi-illuminated, and give the cameras to one of the actors. Obviously, it would have to be somebody in every scene. The movie audience now gets to experience what it is like to be on stage being watched by an audience. Very avant garde.

It could be really awesome, or really boring, or both. The first would make bank, the second would win some film festival awards, and the 3rd would make it Oscar material... it can't lose!

Oh, right, copyright Miseph 2010-eternity (end period is an estimate based on current copyright trends).

So what? (3, Insightful)

valnar (914809) | more than 3 years ago | (#32408216)

Am I the only person who doesn't care how thin they make these display technologies? In regards to HDTV's, I want it clear, accurate, without lag and cheap. Thin doesn't really matter.

Applications (2, Interesting)

alfredos (1694270) | more than 3 years ago | (#32408358)

The ultimate cheating device for exams: One AAA battery and some memory inside the pencil, the display wrapped up and a single switch at the top as the input device.

Book with video: Batteries in the hardcover and the screen like a first page where video references can be looked up.

Even just a good old mobile phone display that doesn't crack under deformation is quite nice an application for this.

hviniciusg (1481907) | more than 3 years ago | (#32411612)

Finally we can make an invisibility suit whit this stuff. Just imagine clothes made from this stuff then you could plug some micro cameras on the front and back and then display it on the suite front and back side, you would not be totally invisible but, given the right research and time we could get a pretty good one.
Just imagine soldiers in the sand whit this suit, or in the snow of forest. The perfect camouflage

Roll-Out Phone (2, Interesting)

Doc Ruby (173196) | more than 3 years ago | (#32412086)

I'd love to have 3x9" phone with a long edge that could pull out a scrolled up display to a full 8.5x11".

Even cooler would be if the scroll could "telescope" out like a radio antenna before scolling, so a few 3" segments could snap out to 8.5", and scroll out to 11". That extensible scroll could contain an 8.5x11" screen in a 3x3 package. Perhaps even a 0.5" thick package, if the scroll can roll really tight.

A real pocket sized phone with a real fullsized display on demand. Cool!

OLED isn't coming anytime soon (1)

JustNiz (692889) | more than 3 years ago | (#32418530)

I'm fed up with all the baseless hype Sony keep generating around OLED. Sony have been showing various "in the lab" examples of flexible OLED screens for years. Decades even. OLED TV has become the "Duke Nukem Forever" of TV tech.

I'll only pay attention to any more new OLED stories when someone makes home-sized (52 inch+) OLED TVs at affordable prices (i.e. same price as LCDs) actually available for purchase.
