The Global Stage for Innovation

CES is the largest and most influential technology event on the planet. Every major and emerging industry is represented, the entire technology ecosystem gathered together in one place to conduct business.

It’s the proving ground for transformative tech such as 5G connectivity, artificial intelligence, augmented and virtual reality, smart cities, sports, robotics and more.



Plessey will be exhibiting at CES 2019 to showcase our proprietary monolithic microLED technology which is set to disrupt the display market and make possible a new generation of augmented reality devices and display solutions.

Visit us on Stand 22048, South Hall 1, LVCC

Our MicroLED technology enables simplified 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 HUDs.

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 MicroLEDs outperform incumbent technologies such as OLEDs.

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

We will be showcasing our developing technologies:

1. MicroLED Illuminator:

  • A Replacement of incumbent solutions used in AR/VR systems and pico-projectors.
  • A single component that replaces three discrete red, green and blue light sources and their associated optics

Plessey’s solution significantly simplifies the existing complex optical system by replacing it with a single light source and integrated micro-optical elements which is located before the relay lens that casts the light onto the DMD or LCoS.

  • Reduces space requirements by up to 40%
  • Provides a brighter source of light
  • In-turn, eliminating costly optical components whilst improving efficiency
  • Can be customised for optimal performance in each application

2. MicroLED emissive display:

A monolithic microLED emissive display solution which will be designed to completely replace the DMD. Including:

  • 1920×1080 monochrome addressable array, with a pixel pitch of 8 microns, running at 60 frames per second (fps) available in Q4 2018.
  • Followed by its first generation 960×540 RGB (wide colour gamut), 60fps, 0.7” (on the diagonal) array with a pixel pitch of 16 micron coloured pixel structured from 4 x 8 micron sub pixels available in Q1 2019.
