MicroLED Displays

MicroLEDs are emerging as the only technology that can provide high luminance in a small format.

As demand for microLED displays is accelerating, with research consultancy Yole Développement forecasting the market could reach up to 330 million units by 2025, Plessey's GaN-on-Silicon is recognised as the only technology platform capable of addressing all of the challenges involved with manufacturing microLED displays in high volumes cost-effectively.

It is also the only viable solution that can enable products that are not only compact enough to be worn without restricting the overall experience for AR and VR applications and in HUDs, but also provide the size, weight, power and luminance needed.


Plessey’s ground breaking IP protected GaN-on-Silicon supports the provision of next-generation products.

  • Widely acknowledged as the 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 out-perform competing technologies such as sapphire and OLEDs

  • Outstanding thermal performance
  • Focussed light emitting surface
  • Monolithic die/array
  • Lm/W maintenance
  • Excellent uniformity
  • Integrated electronic and optical components

Plessey’s ground breaking monolithic MicroLED technology is gaining market traction at an exceptional rate. Key publications covering Plessey’s MicroLED technology include:
