Companies have already showed 100 dpi microLED screens.

Interesting. The weird resolution and small size is definitely telling in terms of manufacturing difficulty, but it's still a decent step forward. Seems it's targeted towards automotive applications, which is understandable (size, desire for deep blacks (don't want an LCD illuminating your car if it's dark outside), and need to avoid burn-in). Wonder what the color gamut and response times are like. From looking at AUOs own news post, the LEDs are 30 microns? 0.03 mm? That is small, wow.

Using its existing gallium nitride (GaN)-on-silicon monolithic process, Plessey will integrate the CFQD quantum dots into selected regions of blue LED wafers to add red and green light, shrinking the smallest practical pixel size from today’s 30 µm to 4 µm, a reduction of 87%. The process will enable the production of smaller, higher-resolution microLED displays in applications such as AR/VR devices, watches, and mobile devices while enhancing both color rendition and energy efficiency.

Then they just need to invent pick-and-place machines capable of handling .004mm LEDs and at a reasonable speed - or invent another method entirely of mounting them to the PCB. After all, a single 1080p display would need 6220800 of them, and a 4k one 4x that (unless they go PenTile with the subpixel arrangement, in which case these displays will be awful). If they take 1 second each to place, that's 1728 hours, or 72 days. Per panel.
