when your pixels are THAT small...does a high defect even matter in final product as you'd never notice em right?

Ah, 127k monitors... now imagine an Nvidia GPU to run that /sarcasm

Oh, that's easy, but 126k of those would be fake pixels.

that's 127K per inch, on a desktop monitor, that'd be at least 2048K

Can you imagine the power it would need!!

Can you imagine how hot the power cable's connector would be... It might even create fusion...

Which you could then use to power it, the energy crisis is over 🤣

This is stupid. Visible light can't be smaller than 380 nm, for purple, and 720 nm for red. I guess you could do blue and red pixels at different sizes, but then you'd have brightness issues. Any pixel size below 1µm, or 1000nm, is therefore pretty much a gimmick.

So sure, make stuff small. Just quit being ridiculous about it and stop when there's zero resolution difference.

I don't think it works that way. I don't think an element that emits a photon of light has to be equal or greater than the wavelength of said light. Pretty sure a single electron can emit a photon in the visible spectrum.

That said, I do have my doubts the technique described in this paper can make all the necessary wavelengths to make a convincing white. In fact, I have to wonder if it will be capable of anything but a single wavelength.

also this makes zero sense, even for AR, as even the FOVEA is less dense than this.

You're not wrong, but that's not what I meant. Yeah, an electron will emit a photon if it needs to release energy (drops energy level).

I don't mean that their pixels can't work. I mean that there's zero utility to going that small. You can't make a camera or eyes with a resolution greater than the smallest size light interacts with (its wavelength). I guess this could be useful for x-ray pixels, if you need to light up a molecule in an x-ray microscope?

I mean, there's technically some other possible uses if you use lenses to spread the light by orders of magnitude, but this couldn't matter for a VR headset. It would only matter if you wanted a thumb sized 4k projector. But even then, it would lack the brightness to be useful.

Okay, it's a cool, but absurd technical accomplishment.

How about ar glasses that project an overlay on your vision without the screen being in the way. Systems that do similar (hololens) are big and clunky.

Good idea.

I still think they're too tiny to ever be practical. But people used to not thing a computer needed a hard drive included in the system.
