The following submission statement was provided by /u/Sariel007:
>LG Disply has developed a 12-inch stretchable display that can be extended in size to 14 inches, the company announced. The displays could one day be used in materials with irregular surfaces like clothes and wearables to display messages on the uniforms of first responders, for example.
>Stretchable displays, or free-form displays as LG Display calls them, can be pulled, bent and twisted. They go a step farther than the flexible displays used in Samsung's Galaxy Fold and other smartphones, which can be folded and bent but not stretched.
>To make the display so stretchy, LG Display built the base substrate material from a silicon similar to that used in contact lenses. It also micro-LEDs smaller than 40-micrometers for the light source, allowing for high resolution and durability. And finally, the company used circuits shaped like springs to accommodate bending and folding.

2 inches is not 20% of 12 inches. Apparently, they are counting on the consumer's inability to do simple math.

Maybe it's 14.4 inches

Holy shit we keep getting closer to easily wearable screens and I’m here for it

The article doesn't mention 14.4 inches. I guess we're rounding 17% to 20%.

A bigger smartwatch screen that is more like a sleeve than a watch.

No need. Wifi 12e charges your devices wirelessly.

All progress is progress. Even if you don't see the use case now, it's very likely there will be one, or that the mechanics uncovered during the research will be useful elsewhere.

I was gonna say that I wouldn't mind and that it seems like an opportunity for some easy beer money, but then I imagined walking around with a massive erectile dysfunction ad on my back.

Have you seen how ungoopy the current displays are? 30% goopier display is revolutionary!

Or 14,4 to 14

Bet they make it a wireless charging thing and partner with grocery stores and cars so if your within say 5 feet it charges.

That’s not true at all. People invent bullshit stuff all the time that flops and has zero future use.

We have those now and no one wants them because they’re fucking stupid
Foxsayy t1_ivvx1wy wrote
What do you mean by invent? Making something new doesn't necessarily mean significant progress.
However, pioneering flexible displays complete with a new fabricated material and spring-archtictured circuitry that is resistant to significant flexion, at least to me, certainly seems to qualify as progress.

Great, I can use it while watching my curved television.
Cautemoc t1_ivwydpo wrote
Reddit has a habit of trying to be negative towards new things. Someone made a curved computer screen that you could bend into a flat screen and Reddit was saying how useless it was, totally missing that at high enough sizes you can use it as a TV too and making it flat lets you sit further away.

The size of a screen is measured across its diagonal. It would depend on the exact aspect ratio, but a rectangle with a diagonal of 14 inches could absolutely be 20% larger than one with a diagonal of 12.
Edit: 14 not 14.4

I understand arithmetic. The article never mention 14.4 inches. Just 14 inches. Just read the article.
Orion113 t1_ivx9wt2 wrote
I did read the article. It was like one paragraph. 14.4 was a Freudian slip, as I saw it in somebody else's comment as I went to make mine.
But none of that changes the fact that a screen or other rectangle with a 14 (or 14.4) inch diagonal can be 20% larger than a rectangle with a 12 inch diagonal. Just as an example, plugging these formulas into Wolfram alpha:
12=(x^2 + y^2 )^(1/2) (formula for the sides of a rectangle with a 12 inch diagonal)
14=(w^2 + z^2 )^(1/2) (formula for the sides of a rectangle with a 14 inch diagonal)
wz=1.2xy (formula stating that the area of rectangle wz is 20% larger than the area of rectangle xy)
And picking a random reasonable value for w, let's say 7, gives us this as a result (all numbers rounded to two decimal places):
Rectangle xy has sides 7.64 and 9.24, a diagonal length of 12 inches, and an area of 70.72.
Rectangle wz has sides of 7 and 12.12, a diagonal length of 14 inches, and an area of 84.87.
Rectangle wz is exactly 20% larger than rectangle xy.
This would work for a range of values of w.

Nowhere in the article does it say that 2 is 20% of 12, either, so what are you arguing about?
