World’s smallest LEDs from a new semiconductor Micro- and nano-perovskite LEDs promise a new generation of display technology 19 March 2025, Zhejiang University ‘Downscaling’, the process of making elementary devices smaller in size, is at the heart of many technological breakthroughs in computing, information display, and human-machine interactions. For example, the downscaling of transistors has accelerated the speed of computers
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.
Edit: my index screens are under 3", just did a lens swap so I have the old eye tubes handy
There are many considerations like FOV would be better with a bigger screen, I think 4" would probably be the max, but still that’s only at 2k ppi, there’¨s a looong way to 127K.
Even with a 4k ppi screen you can do 8k view with just 2".
I think 8K can be made with 2k ppi.
That would be 4 inches or about 10cm wide screen.
