GIMOD – Graphene Interferometric Modulation Displays for VR/AR

Future displays in astronaut helmets will need to integrate Virtual/Augmented Reality (VR/AR) capabilities for training and operation purposes. The screens of electronic devices with standard technologies consume the most power. Reflective-type displays (e.g. e-book readers) consume little power although current technologies cannot provide colourful images nor fast refresh rates to reproduce videos. Graphene Interferometric Modulation Displays (GIMOD) unite the advantages of the reflective-type technology (low power consumption) with those of standard technologies (video capability), in order to cater to the display requirements in future VR/AR visors. The SCALE project, implemented jointly with Gesellschaft für Angewandte Mikro- und Optoelektronik mbH (AMO) and Graphenea S.A., will commercialise the graphene technology to lead the new semiconductor industry of 2D materials.


  • Reflective-type display technology with high contrast in bright environments
  • Ultra-high resolution (>2500 ppi) with low power consumption
  • Ultimate refresh time (>1000 Hz)
  • Caters to the requirements of portable VR/AR visors
