Dr. Andrea Di Falco and colleagues at the University of St Andrews have achieved a breakthrough in holographic technology. They combined organic light-emitting diodes (OLEDs) with holographic metasurfaces (HMs), delicate arrays of nanostructures that manipulate light. This marks the first time both have been combined to construct the basic building block of a holographic display. Their work introduces a compact and cost-effective method of producing holograms, opening possibilities for integration into everyday technologies such as smartphones.
“With this work, we have removed one of the technological barriers that prevent the adoption of metamaterials in everyday applications. This breakthrough will enable a step change in the architecture of holographic displays for emerging applications, for example, in virtual and augmented reality.” said Dr Andrea Di Falco.
