Ok, so is there a pick and place machine that can place these accurately at scale?

Creating nano-PeLEDs, however, was no simple task. Perovskite materials are notoriously fragile and susceptible to damage during conventional photolithographic processes used to pattern LED displays. To overcome this, the research team developed a novel fabrication method involving lithographically patterned windows in an insulating layer. This technique protects the delicate perovskite material while preserving high image quality.
They're creating a whole display panel, not individual components.

Right, so scale is limited to a wafer. Which probably makes sense because the super high resolution does not make sense for larger panels.

I would have expected them to be grown in place, are these really discrete components? Yeesh.

The article indeed shows/mentions a fabrication method with lithographic techniques. The question then is, can that technique scale to larger monitors or is that limited (by wafer size) to small screens, like those for VR-goggles? Perhaps the super high resolution does not even make sense in larger screen applications like monitors. That would require assembly of several 'chiplets' at great precision.... probably cost prohibitive.
