Jasper Display and Plessey Demonstrate World's First GaN-on-Silicon Monolithic Full HD microLED Bonded Displays


SAN JOSE, California, May 14, 2019 /PRNewswire/ -- Plessey, an embedded technologies developer at the forefront of microLED technology for augmented and mixed reality (AR/MR) display applications, today announced a significant milestone in the development of its monolithic microLED displays alongside its backplane partner, Jasper Display Corp (JDC).

Following a continued partnership with JDC including an extensive capital investment in a complete tool set, enabling successful wafer to wafer bonding. Plessey has succeeded in wafer level bonding of its GaN-on-Silicon monolithic microLED wafers with JDC's eSP70 silicon patented backplane technology, resulting in microLED displays that contain addressable LEDs.

Wafer level bonding poses significant technical challenges and has not previously been achieved between a GaN-on-Silicon LED wafers and a high-density CMOS backplanes.

Plessey initially achieved the world's first mechanically successful wafer to wafer bond in early April 2019. This significant success has now been followed by a fully functional, electrical and mechanical bond, resulting in a fully operational microLED display.

Plessey's microLED display features an array of 1920x1080 (FHD) current-driven monochrome pixels on a pitch of 8 microns. Each display requires more than two million individual electrical bonds to connect the microLED pixels to the controlling backplane. The JDC backplane provides independent 10-bit single colour control of each pixel – Bonding a complete LED wafer to a CMOS bckplane wafer, incorporates over 100 million micro level bonds between the wafers.



Dr Wei Sin Tan, Director of Epitaxy and Advanced Product Development at Plessey, said: "This is a momentous milestone in the development of our monolithic microLED display technology. To the best of our knowledge this is truly a WORLD FIRST and we are extremely proud of this tremendous achievement. This is what the industry has been waiting for and opens up a new market for microLED emissive display applications."

JDC's VP Marketing and Product Management, T.I. Lin, said: "Plessey's monolithic microLED array is a great match to JDC's high-density silicon backplane. Our JD27E series demonstrates our ability to deliver what our valuable partner Plessey and the wider industry has been waiting for – silicon backplanes that have been designed with their microLED display requirements in mind."


At SID Display Week 2019, Plessey will unveil its breakthrough cutting-edge microLED technology and demonstrate why its scalable and repeatable GaN-on-Silicon monolithic process is the only solution for next-generation augmented and mixed reality (AR/MR) display products, head-up/head-mounted (HUD/HMDs), smartphones and other microLED based display applications.
