There was a time where I’d get super hyped when reading these kinds of promises. Transparent displays, foldable screens.

Foldable screens have been real and orderable for several years. There problem is, screens need a protective layer on top, and bendable glass tech hasn't caught up. You need to be able to embed a touch layer, have good optical clarity, be scratch resistant, and impart resistant. I've, gently, played with production ready bendable LCDs.

> any of the sci-fi scenarios I had imagined

This is what I don't get. It's entirely possible that I'm particularly unimaginative, but I can't even think of any devices with screens I'd want to bend. All of my devices bend exactly as much as I want them to: none (or at least negligibly).

From a bit of googling just now, it seems that LEDs are effectively “two-way” devices: they emit light, but they can also sense light—just like the way that any loudspeaker is also fundamentally a microphone. Which leads me to wonder: would a microLED array make a better camera input than current CCDs?

Interesting idea,although consider density. A Micro 4/3 camera sensor used on the popular Panasonic GH5 video camera is tiny but captures 4k video, displayed on screens far far larger.

Micro LEDs would need to be far, far smaller to be used as sensors.

Samsung has already demonstrated a MicroLED TV, LG is also on the wagon, yet the article fails to mention at all any of these big display companies and keeps going on about Apple and how it competes with Google and a few startups in the space.

Disappointed that this article has IEEE's brand.

I was excited circa 2016 for OLED displays in laptops but that seems to have died. They were only 2560x1440 panels - I was hoping for 2160p to follow.

Me too! I was so hyped up about it that I got myself a ThinkPad X1 Yoga with an OLED display. But wish I'd realized sooner that putting an amazing display in a shit laptop still leaves you with .... a shit laptop.

Earlier quoted context omitted.

Bending and not-creasable sounds like a tough ask. Those tend to come hand in hand.

It could roll up into a tube instead of folding and creasing.

I'm not convinced about rollable or foldable displays. My phones screen is reachable with one hand, any bigger and I have to use two hands. So I use my tablet. If I need to get work done I use a PC or laptop.

I don't see the point of a display that folds. The display would be worse than any I currently own. It would be more prone to breakage due to the nature of what you're asking it to do.

I think it's one of those technologies that sounds neat, but in reality is not that useful (like 3D tvs)

The weird thing is that we already have “foldable screens.” But all the phone makers have done with them is to give us slightly less bezel on our glass rectangles. I’m wondering if this is a “flying car” thing—if actually handing consumers ultra-thin bendable (but not actually creasable ) panels would be a dumb idea, because consumers would try to exceed their tolerances and break them too easily. (This is also, I th…

Also, aren't they used for curved TV screens and computer monitors?

I'm actually most excited by the transparency. If we get low-cost transparent displays, it will finally make finally make Ishii's clearboard an affordable possibility for remote collaboration. http://tangible.media.mit.edu/project/clearboard/

What am I missing? Couldn’t we just drag a low-opacity video player over an instance of Photoshop for the same effect?

The camera has to be behind the screen and pointing through it

I don't even think it sounds that neat. Just silly.

3D TV's, on the other hand, I love and am very sad that they're now not being produced... Just when the size and resolution of TVs is getting good enough to make them worthwhile.

What about just curved displays? Like in a car, it seems there could be some interesting applications (screen embedded in windshield, or wrapped around the dashboard or center console). Is curved glass tech also a barrier, because I feel I've seen very few applications of curved displays other than TV's.

Actual applications do exist. :)

Lots of cell phones have screens with a slight curve to them now days. Or in the case of Samsung's edge displays, a rather dramatic curve.

To the best of my knowledge, neither display in those fitness products was flexible, just bendable.

I know that as of a few years ago, Corning was hard at work on flexible "glass" for flexible displays.

Sounds like a pretty good idea for a tv display.
