Axus/Plessey Partnership
Axus partners with Plessey Semiconductors to help bring high-performance GaN-on-Silicon monolithic microLED technology to the mass market.
Using tooling from Axus and optimised processes, Plessey Semiconductors has achieved a successful wafer to wafer bond of a 1080p microLED display 0.26” diagonal to a 3-micron pixel-pitch backplane. Much smaller than the 0.7" diagonal 8-micron pixel-pitch active-matrix display previously demonstrated.
