The fully addressable microLED display modules result from their previously announced strategic partnership to develop and introduce GaN-on-Silicon microLED based microdisplay solutions for AR/MR applications.

CP and Plessey engineering teams have successfully fabricated functional microLED display modules combining CP’s industry-leading high speed digital low-latency display backplane with Plessey’s breakthrough GaN-on-Silicon monolithic microLED array technology.

Plessey’s team produced the microLED array wafer bonded to CP’s backplane wafer at its Plymouth, UK, facility. In turn, CP’s team assembled and packaged display modules from the bonded wafer pair at its Phoenix, AZ, USA, facility. Both teams are currently performing initial characterization work at CP’s Vancouver, WA, USA, facility.

“Today’s milestone achievement is a direct result of the close working relationship between Plessey and CP development teams,” commented Mike Lee, President of Corporate and Business Development at Plessey. “This successful proof-of-concept demonstration validates both companies’ goals to produce the industry’s highest performance microLED display modules that deliver improved brightness at the smallest pixel sizes, higher frame rates, with extended bit depth at the lowest power consumption to best serve next-generation emissive display based AR/MR smart glasses and Heads-Up/Head-mounted displays (HUD/HMDs) applications.”

“These prototype microLED displays provide important confirmation that Plessey’s monolithic GaN-on-Silicon IP, fabrication technology and bonding processes match perfectly with CP’s industry leading 3.015 micron pixel pitch 1080p (1920×1080 pixel) backplane design to deliver compact high resolution microdisplays. Combined with CP’s NOVA high-performance display driver architecture, these microLED displays support an industry standard MIPI interface to take advantage of CP’s unique display pipeline solution designed for the real time needs of AR/MR applications. CP’s display drive technology is extensible across multiple display technologies enabled by full software configurability, allowing customers to build their systems for specific power and performance needs”, added Yiwan Wong, Compound Photonics’ CEO.
