LG's New Stretchable Display Can Grow By 50%

An anonymous reader quotes a report from Tom's Hardware: LG Display, one of the global leaders in display technologies, unveiled a new stretchable display prototype that can expand by up to 50%. This makes it the most stretchable display in the industry, more than doubling the previous record of 20% elongation. [...] The prototype being flexed in [this image] is a 12-inch screen with a 100-pixel-per-inch resolution and full RGB color that expands to 18-inches when pulled. LG Display said that it based the stretchable display on a "special silicon material substrate used in contact lenses" and then improved its properties for better "stretchability and flexibility." It also used a new wiring design structure and a micro-LED light source, allowing users to repeatedly stretch the screen over 10,000 times with no effect on image quality.

Wearable display

Can't wait until this is available on Mouser or something. Even if you aren't going to wear it directly, having it as a wraparound screen means it could fit basically anywhere.

I asked your mom. She said your 50% isn't cutting it but she loves you anyway.

as a man i can grow way more than 50%, especially on cold days.

And can you guess how normal people will be able to afford it? ADVERTISING! You'll be a walking billboard for whatever company sponsors you for 10 out of 15 hours a day. But I'm sure they'll figure out a way to make the ads sort of blend with your colors, except for two minutes twenty out of each fifteen minutes, where the advertisers own your clothing. That's all I'm seeing here, when it was mentioned on the morning news as being set up for uniforms and other clothing. It'll be advertising. That's what all

I can wait.

[Gravis Zero]

With a "100-pixel-per-inch resolution", I can wait because that's really low res.

Actually thats kinda neat

[ZERO1ZERO]

Having a small display that can stretch to be bigger but keeping the same ppss (pixels per screen size) Because typically if i want a bigger screen i will be farther away so the 'lower' resolution wont be an issue. Theres already enough pixels for most things. Ive actually went back to a 27â 1080p screen recently because its just easier not dealing with scaling and i can read everything fine. Im all for a 2" square iphone that can stretch to a 2x6" device maybe this is apple thing not a flip but

Re: Actually thats kinda neat

[SuperDre]

The ppi won't be the same, if you stretch the screen the pixels stretch with it, so the ppi lowers the more you stretch it. It's not like extra pixels appear when you stretch.

Re: Actually thats kinda neat

[ZERO1ZERO]

For a give apparent size it will be. Like how my laptop on my lap whilst sitting on couch screen *appears* to be the same size as my much larger tv which is 4 metered away.

Re:

[SuperDre]

But the PPI of your TV (ex. 50") is much different as the PPI of your laptop (ex. 15"), if they are both the same resolution (ex. 1920x1080).

Re:

yes when i said pixels per screen size i really meant to say pixels per apparent screen size...

Special silicon?

[necro81]

The summary (and article) says that "LG Display...based the stretchable display on a 'special silicon material substrate used in contact lenses'". That really doesn't sound right. Silicon is a brittle material: ya know, the stuff they make computer chips out of. Also it's the main component of glass, which is world-renowned for its...not stretchy behavior.

Given the reference to contact lenses, and the stretchiness in general, they surely must have meant silicone: the stuff used for "rubber" spatulas a

polydimethylsiloxane or a variant with all the electronics embedded.

silicone IS a "silicon material" you doughnut.

Re:

silicone IS a "silicon material" you doughnut.

I'm well aware. But one does not usually frame it that way, because the properties of silicone are so very different than bulk silicon. You may as well say that Pepto-Bismol is a "bismuth material", rather than calling it a medicine for GI symptoms. Or describe hemoglobin is an "iron material" - implying it's akin to steel. It may be technically, pedantically true, but is more likely to come across as uninformed rather than well-informed.

Re:

"Silicone" != "Silicon"

Silicon is what electronic bits are made out of.

Silicone is what soft pliable kitchen utensils (spatulas, oven mitts, scrapers, etc.) are made out of.

Resolution?

[asylumx]

I know this is just a prototype but I wonder how they will deal with resolution when it stretches. Can they detect how far it has stretched and adjust?

old joke

[jslaff]

It's 27" but if you rub it it's 42".

Grower not a shower

[esperto]

interesting technology but every time a new display tech or similar is shown the marketeers only think about is putting them on fridges and clothes, and literally no one wants that, i think would be cooler to have this in a drop-down screen for presentation, replacing projectors, or more likely in curved and malleable advertising posts.
The resolution is not great at 100ppi (at least for now), but one important thing they didn't say is durability, if it can only stretch 100 times it would not be that useful,

Re: Grower not a shower

[Tomahawk]

They literally say in the summary above "over 10,000 times". So where are you getting "100"?

The 10,000 is likely just how much they tested it too, so not necessarily any type of upper-bound.

Centerfold gag

[TWX]

Seems like the sort of thing that movie directors and screenwriters will use as a sort of centerfold gag in the future, replacing the old trope of the kids opening the magazine sideways for a trifold page to unfurl.
