    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.

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

            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.

              I'm thinking lithography. The higher the DPI the smaller you can make your components.

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

                  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.

                    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?

                          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.

                            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. 👍

                              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.

                                    im not saying it wouldnt be a challenge, but isnt solar panel tech possible here?

                                    it just has to be really power efficient.

                                      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 🤪
