Micro-OLED displays with 1080p (1920x1080) resolution have been around for a few years now, but a group of German researchers has taken things to the next level. They've engineered an OLED pixel so small that an entire 1080p display could fit into a single square millimeter, potentially changing the game for wearable displays …
I foolishly looked this up on something called The Internet :
https://en.wikipedia.org/wiki/Hydrogen_silsesquioxane
"Hydrogen silsesquioxane(s) (HSQ, H-SiOx, THn, H-resin) are inorganic compounds with the empirical formula [HSiO3/2]n. "
there is a nice image of the standard molecule.
So far it isn't a pixel, it's an orange sub-pixel - you need at least three colours for a colour display pixel.
It also appears to run too hot to have many close together - they were only testing one emitter.
So far, anyway. The manufacturing technique seems reasonable, so the next steps will be more colours and improved efficacy.
Very exciting.
