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?
Contact lenses?
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.
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.
you can beam tiny amounts of it ota. it just needs to be very power efficient.
im not saying it wouldnt be a challenge, but isnt solar panel tech possible here?
it just has to be really power efficient.
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)
