How did Samsung and Huawei make those foldable screens? | Upscaled

  • Published on May 17, 2019
  • 2019 is the year we're going to see foldable OLED screens in phones and maybe even laptops and tablets. If the early setbacks with the Galaxy Fold weren't indication enough, there's a lot of complex challenges around making a device that bends.
    Despite this, flexible OLEDs have been around for more than a decade. In this episode, we dig into all the parts that have to work together to make a foldable screen.

    A great video - looking forward to more.
    BUT I HAVE ONE GRIPE: I you want to be scientific - for the love of G'd - please use Celsius or even Kelvin heat measurements - forget Fahrenheit - nobody knows what that means anyway!

    I find it hard to see who would like a foldable screen, when bigger screen can do the job. I don't need big screen.

    Not well apparently with how easy they are damaged or creased. It’s a cool concept, but it creates too many possible points of failure.

    See, that’s the problem. They don’t.
    All the have made is a bendable screen and put it into a foldable phone. If they had made, what they have claimed earlyer, a phone that snaps around the whrist, when its not in use, that would have worked. Foldable phones do not work and never will, with the current screen matrix.

    Samsung spent years researching and working to create a foldable display, even spending 5 years just to make an inhouse glue, and apparently huawei did the same? This video only talked about what samsung did. It didn't even mention huawei except to reference. Did not meet the title

    When I saw that Samsung and CCP’s huawei had foldable screens, I looked to see which company they stole it from, those companies have very small r&d budgets, and low creativity. it will come out sooner or later that it was stolen, you watch.

  • Senor El Joynes

    In the future they might not need the diode layer in these screens as light emitting transistors already exist, they don't have any yet (to my knowledge) that produce red, blue, or green, or that can operate at high enough frequencies, but it would be cool in 50 years to see the need for one of the layers in these flexible screens to be eliminated, allowing for them to be even more flexible. One thing I'm curious about is how the bending of the screen deforms the transistors and diodes and changes their physical properties, which probably would need to be accounted for by the engineers' calculations.

  • Tim Ogul
    Tim Ogul 25 days ago

    I think they're going the wrong way. Don't fold, *ROLL.* Make a phone that has the resting shape of a small mag-lite flashlight, and then you can "extract" a large screen from it like pulling out a roll of film. Have some sort of telescoping or interlocking framework that will support this extending screen and keep it stable when fully extended. This would allow a very large screen to be portable, but I would hope that having a smooth retraction into a cylindrical housing would put less direct stress on the screen than a 90 degree bend. The only issue would be in how stable they could make it when fully extended and handheld.

    LCDs still have better refresh rate, OLEDs mostly go up to 60 Hz and One Plus just now made a 90 Hz oled.
    Meanwhile iPad Pro from 2017 goes up to 120Hz on LCD.
    There rarely is a clean split between obviously better and worse technology. OLEDs have burn-in, cost more etc

  • Ark01000
    Ark01000 25 days ago

    I beg to differ. There are some amazing LCD screens. I have a rare for of migraines and OLED trigger mine so much more than LED. Any screen for a long time ends up making me sick. But OLED really kills me. So anyone with similar problems I would suggest using LCD screens. They also have become a lot more colour accurate and actually can look very sharp( as seen on the IPhone XR)

    You will need glass in the fordable screens as they don't stretch and create a crease. But the glass is so thin that it will break very easily upon impact.

  • Daniel Smedegaard Buus

    Hi! In English, when a noun starts with a vowel-sound, such as "apple," "8-ball," or "n-type," you pronounce the article "the" as "thee." However, when the noun starts with a consonant sound, such as year, components, response, galaxy, first, galaxy, note, galaxy, hosts, hosts, fold, backplate, or glue, you pronounce the article "the" as "thuh." It's often difficult for non-native English speakers to get right at first, which is probably why you get it wrong, but it's a super common error among foreigners, so no need to feel bad about it :) But now you know! Hope it helps! Cheers!

      If they really found evidence for espionage, they banned Huawei as a signal that this has serious economic consequences, even if it means that they are also damaging themselves.

  • Scott

    I think these companies are sort of missing the point... I want a large display, I will indeed compromise. Why the heck can't they just work hard on an OLED that has a nearly zero border and put it next to another one, no bendy plastic bits. So basically do what has already been done before, but step it up a notch (but please, dont put any notches on it). Don't make me get two Samsung S10s and use packing tape to stick one next to the other, then just flop one onto the other... seriously, if that was done full tilt, I would buy that.

    I saw a paper where they used 4 layers of graphene as the anode to allow the screen to be flexible, peeled off the copper sheet it was grown on and deposited onto a plastic sheet using a heat sensitive adhesive .... and while I was writing the comment you went ahead and mentioned this was a future possibility. Never mind.

    I’m just going to stick to an iPad mini because it is the only affordable tablet to fit in a pocket without folding.

  • Whole Food Plant-Based Man

    You really did your research on this one. Good job.

  • Whole Food Plant-Based Man

    Instead on a single screen that folds, why don’t they put 2 screens side by side, and they can fold it along the gap? Then they use software to decrease the latency between each half of the screen.
