World’s smallest LEDs from a new semiconductor: New LED displays packing 90nm 'virus-sized' pixels can deliver 127,000 PPI visuals.

we already have tiny flexible screens and the means to beam video data to it wirelessly. we also have microscopic chip litography to handle it.
But no small or translucent batteries

I'm thinking lithography. The higher the DPI the smaller you can make your components.
Maybe for low end lithography, you can't use normal light for anything high end, already at 7nm it requires EXTREME ultra violet. And the lamps for that cost 100s of millions, to make the shortwave light necessary.
But for low end, it could possibly be used for ultra fast and cheap cycle between tape-out and production?

Non-human use cases, would be one. Like, having the ability for machines to "see" highly detailed imagery via camera. Just spitballing. My eyes are shit, so a screen that cool will never be of use.
Maybe, but it would be more logical to simply bypass screen to eye camera, to just transmit the signal from the original camera directly.
But hypothetically yes, that could possible be a use in a future scenario. -
For Christmas tree decorations!
That's it! An ultra fine web of microscopic lights simulating the Christmas tree shrouded in fog.
They have to hurry up and make that, I want to see what that looks like.What a cool idea.

How would you power them without a battery? It doesn't matter if it's really power efficient if it isn't getting any power.

im not saying it wouldnt be a challenge, but isnt solar panel tech possible here?
it just has to be really power efficient.

Wirelessly. Like an NFC tag.
Not saying it would be super practical but if you custom shaped them you could put a wire coil around all of the non seeing parts of the eye.
Just make it sodium based, and a good crying jag will replenish the battery.

I think 8K can be made with 2k ppi.
The bigscreen beyond used 1 inch displays so this could be useful for getting much higher resolutions in a smaller form factor. I don't think my Index displays are even as big as 4 inches so I guess that explains why all the super high res headsets are so huge.

the obvious solution to this problem is running a convenient wire from your eyeball 🤪

you can beam tiny amounts of it ota. it just needs to be very power efficient.

There are many considerations like FOV would be better with a bigger screen, I think 4" would probably be the max, but still that's only at 2k ppi, there'¨s a looong way to 127K.
Even with a 4k ppi screen you can do 8k view with just 2". -
127000 PPI e-ink display. Allows transparency.
Needs some kind of extremely tiny body heart driven power source, WiFi chip and processor...
Closer and closer to cyberpunk era tech (and oppression)

Omg a VR display. Yes.
