Well Lenovo just demonstrated one at CES: https://www.cnn.com/cnn-underscored/electronics/lenovo-think...

LG has one (but they make their own screens): https://www.lg.com/us/lg-signature/rollable-oled-tv-r

The lenovo video shows you everything except how it works. It's the one I watched to come up with "isn't this just sliding doors without Gwyneth Paltrow?"

The LG one has a plausibly large box. I can believe this is rolling up like a scroll. Or a toilet roll.

The Lenovo video literally shows you a working device from the floor of CES. By how it works do you mean instead... (a) where the excess is stored, (b) how it's rolled, (c) what the (surely quite valuable) IP is?

Yes. How is exactly what I meant, not "does it work" but "how does it work" which is why the word "how" was in there.

That IP will be protected by patents, it won't survive by secrecy the first ifixit teardown or one of the bill of materials calculation sites will remove that veil.

No need to be snarky, googling "samsung rollable display patent" isn't so hard:

I thought the meta or prevailing wisdom was software developers / programmers should NEVER™ read patent documents?

Thank you for that. It's almost exactly what I expected with a twist. It's not a roll up. It's a roll around. I apologise for the snark.

That patent shows the kind of screen they use in those phones that you fold in and out.

Like for example the Samsung Galaxy Fold Z phones.

I wonder if they use the same kind of folding/rolling screen or not in that laptop they show in the OP article.

When I last looked at these kinds of phones in the store I found the screens super underwhelming. Maybe it has improved since.

That's probably not what most people here understood with "rollable". It doesn't form a a roll like a roll of paper.

And the whole LG site about it shows... a box and a "add to cart" button (which doesn't work). Do they really expect us to buy the cat in the bag sorry in the box?
