IMO the only company which has the ability and resources to speed up Microled's viability is Apple. They're not saying. Plessey and others are selling a pig in a poke, difficult to fabricate for Large Displays more so for microled. Hopefully, fingers crossed, volume manufacturing for Microoled looms.

In R&D for several years, microLEDs are used to make displays for TVs, watches and head-mounted systems like the Google Glass. But microLEDs are difficult to make and expensive. That’s why mainstream commercial displays using microLEDs are not available today and won’t appear for several years.
