Omg a VR display. Yes.
What is the use case for 127000 PPI?
AFAIK retina start about 450 for phones, that are already pretty close view.
The closest id probably VR that can utilize 1000+. (AFAIK 2000 is REALLY good!)
But that leaves more than a factor 60 that I can't see much of a use case for?
VR can maybe use 5000, I seriously doubt it will make any difference above that.
So where is more than 5000 necessary?
I'm thinking lithography. The higher the DPI the smaller you can make your components.
SLA printers would definitely benefit, provided these tiny LEDs can put out the required UV.
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.
Contact lenses?
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)
Very creative, maybe some day. But I think it will require serious developments in other areas too. Like technologies we don't even have yet.
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
the obvious solution to this problem is running a convenient wire from your eyeball 🤪
don't necessarily need one if they are power efficent enough.
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.
you can beam tiny amounts of it ota. it just needs to be very 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.
im not saying it wouldnt be a challenge, but isnt solar panel tech possible here?
it just has to be really power efficient.
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. 👍
VR but right up in my face?
You can't make lenses to focus properly at shorter distances I think, or you would get an extremely narrow FOV.
vr, ar, xr, medical technology, etc...
So they can make my TV smaller? Nice.
or maybe they can make 8k per eye AR glasses?
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.
Edit: my index screens are under 3", just did a lens swap so I have the old eye tubes handy
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".
Finally!
Maybe even 16k.
