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…

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.

Maybe it was the content, but what I saw on 3D tv was just flat characters in a 3d environment. It felt very weird. The clunky glasses were a bit rubbish. All a bit weird and crap.

I don't understand in general why OLED is taking so long to be mass produced for TVs and monitors. It's like just now becoming mainstream, with what seems like two actually purchasable products.

I have an LG OLED TV, and I would recommend against purchasing an OLED for monitor use. Burn-in is still a huge issue. I've used mine for about a year and the red channel is full of distracting burn-in patterns from still elements on my screen from things like wallpapers, tiled window borders, taskbar/docks, HUDs from games, etc. Does anyone know if MicroLEDs could suffer from burn-in as well? I.e. do they also degra…

LG oled TVs are all white with a color filter.

There was a time where I’d get super hyped when reading these kinds of promises. Transparent displays, foldable screens. Truth is, we’ve been seeing working prototypes at events like CES for more than 15 years. I’ve come to realize the mechanics of these companies are similar to the car industry. New technologies are presented for the same reason car companies present strange concept cars: PR

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…

So are you saying that you want an actual foldable phone? Putting aside the technical challenges of getting the chassis and other components to also fold, I struggle to understand why this would be a desirable product.

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/

I would love to have a transparent dashboard display on my desk. In fact I'd pay a lot of money for it.

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.

Why?

Because optics increase in size with sensor size. The lens for a TV sized camera would be gigantic.

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

Bendable displays require bendable batteries, bendable circuit boards, bendable cases, etc....

All of which we know how to do. A display IS a circuit board by the way.

I must say using foldable displays to have 2 display sizes does seem very useful to me. If you can ignore the blatant cheesyness and sexism this video does illustrate it pretty well.

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?

If so, this could allow front facing cameras and webcams to be placed dead center of the screen, allowing 0 bezels without awkward camera placement like Dell XPS has.

Ok, so it's not about sensor size, it's about lenses. You don't really need lenses though: https://petapixel.com/2017/06/22/caltech-made-sensor-lensles...

The entire screen would have to serve as a sensor, the pictures will have the same resolution as the screen.
