About

Plessey has established a state-of-the-art semiconductor processing capability for developing and manufacturing microLEDs.

Plessey started a commercial agreement with Meta to help them achieve their vision of the next computing platform centred around people.

Plessey delivers native Red InGaN LEDs on Silicon for world-leading microLED displays.

Plessey achieved the world’s first GaN-on-Si monolithic wafer-to-wafer bonding.

Plessey demonstrated the first HD 8-micron pixel display at SID Display Week.

Plessey used GaN-on-Si to emit native green, an industry-first.

Plessey pivoted to focus on the research and development of microLEDs.

Using GaN-on Silicon technology and semiconductor expertise, Plessey manufactured solid-state lighting, horticultural lighting, and medical sensing products.

Plessey acquired rights to GaN-on-Si technology by acquisition of CamGaN startup from Cambridge Enterprises.
