• A graphene enabled floating display is based on the principle of holography invented by Dennis Gabor, who was awarded the Nobel Prize in Physics in 1971. The idea of optical holography provides a revolutionary method for recording and displaying both 3D amplitude and phase of an optical wave that comes from an object of interest.
  • The physical realisation of high definition and wide viewing angle holographic 3D displays relies on the generation of a digital holographic screen which is composed of many small pixels. These pixels are used to bend light carrying the information for display. The angle of bending is measured by the refractive index of the screen material – according to the holographic correlation.
  • At this moment, the demonstrated graphene 3D display can only allow images up to 1cm. But there is no limitation for the up scalability of this technique. It is projected that graphene 3D display at tens of centimetre scale, perfect for the wearable displaying devices, will be available within five years.
