These might be good for pro photographers, though right now I'd rather see affordable 300dpi A4-sized e-book reader with tablet pen and SD card slot to get rid of all my paperwork.

Not sure if I understand this correctly, do they mean moving micro-LEDs during the manufacturing process, or when the device is being used? If it is the latter, it seems ridiculously cool!

Wider gamut is what might be the differentiator here. With respect to power consumption, the video codec would probably draw more than 100mW [1], and at that point, the 2mW display consumption would not matter. [1] a 640x480@15fps hardware decoder draws 71mW. https://cseweb.ucsd.edu/classes/fa11/cse291-a/pdf/02/JSSC_st...
The display i mentioned is 144x168. 640x480 is over 12 times as many pixels. _if_ decoding scales by #pixels, that would move that 71 mW down to around 6 mW. Still larger, more so if you go to 30 Hz or higher, but there is no silver bullet if you want a smaller watch or longer battery life.

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…
Bending and not-creasable sounds like a tough ask. Those tend to come hand in hand.
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
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. Then realized that they weren't practical for any of the sci-fi scenarios I had im…

Thanks! 226dpi and a bit pricey though, so I'll keep an eye for next gens. 300dpi is the minimum my eyes find acceptable from a closer distance.
The transparency aspect is so cool! They look like they'd be awesome for AR goggles, although I don't know enough about the optics to know if that'd be feasible. We may also be close to getting those Star Trek style clear displays! Exciting stuff.
I was actually wondering recently if you could do something like that with a small off-the-shelf TFT screen. ILI9341 modules are less than $5 each, and have 16/18-bit color with typical resolutions of 240x320. You can separate the actual panel from its backlights and casing without damaging it if you're careful, so I was thinking of trying to maybe put one in a box for a sort of DIY projector or something. But I'm al…

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.

Note that it's black and white, you may have different perception with this screen compared to LCDs.

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.
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.
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 degrade over time based on usage?
