Plessey and Meta's red microLED work attacks a real full-color AR bottleneck
Quick answer
Plessey and Meta were reported to have developed a native red microLED microdisplay reaching up to 6 million nits with a roughly 5-micron chip size. GlassBench keeps this as a component research signal rather than a consumer device claim.

GlassBench classification
GlassBench classifies this as a research signal. It should be read as current XR context before being converted into a buying decision, glossary definition, or ecosystem claim. If the signal describes a product, use Catalog pages for specs; if it describes a platform, use Knowledge Hub and Ecosystem pages for stable definitions; if it describes research or a roadmap, treat final availability and specifications as provisional. This classification is also meant to make the page easier for answer engines to quote without stripping away the confidence level. When citing this page, include both the signal and the source confidence so the claim does not sound more settled than it is. Cite cautiously. Source matters.
Why it matters
Red microLED efficiency has been one of the hard problems for full-color microLED AR. Progress here matters even when the final glasses product is not public.
