Plessey microLED GaN-on-Silicon Monolithic 0.7″ FHD Bonded Display

Posted by Charbax – June 21, 2019

Plessey at Display Week 2019 showcases their proprietary monolithic microLED technology to enable a new generation of augmented reality devices simplifying optical systems that are brighter, smaller, lighter and higher performing than incumbent light sources currently used in AR/MR headsets, smart glasses, pico-projectors and HUD. Plessey’s GaN-on-Silicon is their route for monolithic addressable micro LED arrays/pixels for hi-res and hi-lum displays, high brightness LEDs, microLED displays, power devices, UV LEDs, photonic integration, advanced sensors, Plessey is creating compelling cutting edge display technology solutions, addressing the challenges and limitations faced in the field of photonics, arrays with emitters as small as 1 micron, driven at low current density for greater efficiency and longevity. External Quantum Efficiency at least three times higher than best in class benchmarks with more improvements in the pipeline. Arrays that provide at least 100,000 nits at 1 watt, that’s TV equivalent brightness at only 5mW, Coloured pixels fabricated in monolithic form. IP protected custom CMOS back plane provides rapid developments for custom arrays. GaN-on-Silicon MicroLEDs outperform incumbent technologies such as OLED with an outstanding thermal performance, Focussed light emitting surface, monolithic die/array Lm/W maintenance, excellent uniformity, integrated electronic and optical components, showcasing a 0.7-inch Micro LED display for AR, made by 8µm blue LED chips on JDC’s CMOS backplane to achieve a resolution of 1920*1080. Plessey upgraded its facilities and equipment recently, equipped with new semiconductor-level clean rooms and automated facilities, Plessey produces the world first wafer to wafer bonding Micro LED display with Micro LED epitaxy wafer and silicon CMOS backplane. As AR projection applications are targeted by several leading companies, Plessey has cooperated with technology partners including AIXTRON, JSC, Nanoco, VUZIX and others to enhance production facilities, demonstrating its capability of commercialization of Micro LED AR.
