Also, more than 5 yrs after Galaxy Fold (I've never seen or held one IRL):
is it really that valuable to have "marginless" foldable displays?
Often times, users will divide the screen into halves, at least, when using large resolution.
And users are also not too interested in curved or mangled output surfaces, the ideal is an evenly lighted 2D surface.
If you were working on military technology, that's irrelevant of course. Then, the consumer tech is just a small venture capital driver.
No "foldable" real currently comes close to two flexable screens placed close to each other.
Consumers have repeatedly rejected this hype.
The only interesting value is in completely flexible material with fixed-distance OLEDs on it, and that's a very complicated engineering problem approaching a digital "invibility coat".
In-between these extreme uses, I struggle to see the benefit of foldable screns.
A cheap and robust e-ink screen would be a welcome exception, but I have no idea how much the science overlaps with marginless, foldable LED panels.
