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

  What is the use case for 127000 PPI.
  AFAIK retina start about 450.
  VR 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.

    Contact lenses?

      Very creative, maybe some day. But I think it will require serious developments in other areas too.

      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)

    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.

    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?

    • Buffalox@lemmy.world ⁨2⁩ ⁨months⁩ ago

      You can’t make lenses to focus properly at shorter distances I think, or you would get an extremely narrow FOV.

  So they can make my TV smaller? Nice.

    or maybe they can make 8k per eye AR glasses?

    source

    • Buffalox@lemmy.world ⁨2⁩ ⁨months⁩ ago

      I think 8K can be made with 2k ppi.

      Maybe even 16k.

    Omg a VR display. Yes.
