UCLA Develops Stretchable OLED Display

cylonlover writes "While there have been some intriguing developments recently in the field of stretchable electronics and flexible OLED displays, one thing we haven't heard much about is stretchable displays. So is it possible to make a screened device in which every part of it could be stretched. The answer could now be yes, with news that researchers from UCLA's Henry Samueli School of Engineering and Applied Science have demonstrated a stretchable polymer light-emitting device."

Not a stretchable display - a stretchable light (4, Informative)

Animats (122034) | more than 2 years ago | (#37269518)

It's just a stretchable light source. There's no image. Making a display requires a lot more components and interconnects, which also have to be stretchable.

It's not that big a stretch of the imagination.

Which part? The beginning 2 second introduction or the 1 second of stretching?

Re:damn (0)

Anonymous Coward | more than 2 years ago | (#37269708)

On my display I can stretch it out to 5 seconds if I pull really hard.

Aspect ratio? (1)

bjoast (1310293) | more than 2 years ago | (#37269498)

What about aspect ratio? Won't that be a concern?

Re:Aspect ratio? (1)

Reverand Dave (1959652) | more than 2 years ago | (#37269556)

it's not meant to be anything but a light source initially. Aspect ratio is only a concern for displays.

Re:Aspect ratio? (1)

Dekker3D (989692) | more than 2 years ago | (#37269670)

Slashdot's choice of titles tells us that this -is- a display. I was confused at first too, but it seems to be just lighting like you said.

Re:Aspect ratio? (1)

Reverand Dave (1959652) | more than 2 years ago | (#37269978)

I could see some fun things with this if they did eventually turn it into a display. it would give a whole new meaning to "nude suit".

Re:Aspect ratio? (1)

Hylandr (813770) | more than 2 years ago | (#37287420)

This would be useful for signs, by stitching together different colors. We could get away from those huge hollow signs filed with incandescent tubes, and just plaster *everything* instead with these things...

They expect us to believe this won't be an issue? That's a stretch...

Good news, even for relatively normal applications (1)

Anonymous Coward | more than 2 years ago | (#37269626)

Nice. Because stretchability is what you need to make bendability work in real life. The tighter the bend, the more the inside compresses and the outside stretches. Also gets worse as you add thickness for durability (unless you keep all stretch-sensitive components in the middle).

So when you add that 1mm thick plastic backing to your flexible display to increase durability, and then it gets creased anyway, this could be the difference betwen a working display and the pile of crap you'd have with today's "bendable" displays.

I know often times small milestones can make news because of the ramifications for future use, but this seems really early to see much of anything useful out of it. They probably should have held on to the press release until they did a more application-oriented proof of concept.

Seriously. I've heard all of this stuff that never ever sees the light of day. Stretchable OLEDs? What ever happened to the regular ones that never appeared on the market? What about SEDs?

Fuck it.

Yes, I'm jaded. Call me when you have a product on the market. It's like all these cures for cancer that work in a petri dish, but fail in the real world for the last 40 years.

All this is, is a funding lure. That's all. Trick someone with deep pockets into funding it with semi-plausible results until you run out of money and then start the next "big thing in a lab only" project.

OLED has hit the cell phone market. Samsung has rolled out AMOLED onto some of their phones. The problem with OLED is that it's more expensive than regular LCDs which are a more mature technology. You're too impatient, look to other display tech. We've had LCD tech out for quite some time, but it's only been recently that everyone has thrown out their CRT displays.

I have many products containing OLEDs. They're difficult to avoid these days. If you have a cellphone or other device with a tiny screen, it's as likely as not it's OLED and not LCD.

Re:Lab? Who gives a shit? (1)

mattack2 (1165421) | more than 2 years ago | (#37271362)

Though it's very small, the original Series 3 Tivo has a OLED on it, and it came out almost 5 years ago (wow).

The OTHER way to be jaded is TOWARDS the funders. These are people coming up with good ideas, but the capitalist system is failing to develop them.

Seriously. I've heard all of this stuff that never ever sees the light of day. Stretchable OLEDs? What ever happened to the regular ones that never appeared on the market? What about SEDs?

We've had OLED TVs. Hell, Sony ended up killing it due to poor sales. Cellphones have OLED screens (though I really wonder - do they really have such poor viewing angles? Every OLED demo one I've seen goes awfully tinted (blue or red) when viewed from the side).

MP3 players have had OLED screens for years as well.

Problem is, well, large OLED screens are expensive. LG was supposed to demo a 37" one at CES a few years ago (cost - over $10K - when a 37"-odd LCD was going under $1K). And Sony's qHD OLED TV was clearanced at $1K, for a 10" screen.

I'm not sure what's going on. The ones on cellphone screens are nice head-on (I've used a coworker's Nexus S), but tilt it to the side a bit and it went all blue-tinted. Some of the in-store demos I've seen are pink or red tint (but nice head on). The Sony TV was really nice (bright and wide viewing angles), so it's not the technology, I don't think...

Of course, the Sony OLED TV also flickered like an old CRT TV (even worse I think) when it displayed white. Bleh.

Sockatume (732728) | about 2 years ago | (#37276278)

Congratulations on the trifecta: you lack the facts, perspective and humanity needed to understand the story, yet you've posted anyway. Let's do the blow by blow:

"What ever happened to the regular ones..."

They're on the market now. 4" models are now ubiquitous in cellphones, and Samsung has announced a mainstream, competitively-priced tablet with a 7-inch 720p OLED display.

"It's like all these cures for cancer that work in a petri dish..."

There can be no cure for cancer. Cancer is an umbrella term for a variety of conditions which cause the unwanted growth and proliferation of tissues in the body with deleterious effects. As such there are a wide variety of cures. They start at the petri dish, and they're gradually whittled down to the ones that actually work. As a consequence many "fail in the real world" but an astounding number succeed. Thanks to these treatments, the survival rate for many cancers - not enough, never enough, but many - would make a doctor from the 1970s fall to his knees in awe.

"All this is, is a funding lure..."

So your conclusion, based on facts that are wrong and a perspective on them that could not be more misguided, is that these people must be crooks.

You're an imbecile in two different ways, and you're a dick.

Video mask, make a mask of the material that conforms to your face and plays video of whatever, other peoples faces, maybe have a minicam on it and set it to mirror who ever you're talking to.

DSS11Q13 (1853164) | more than 2 years ago | (#37271004)

practically, there's not much difference between an iphone, an ipad, and a low end pc apart from the screen size. whoever can make this work practically to will have the one technology to rule them all.

It is a 1x1 pixel resolution 1 bit color display with variable aspect ratio.

This is a perfect solution to when you download a movie and the aspect ratio is wrong. :)
