Media reports excitedly announced that the revolutionary material graphene could soon enable 3D 'holographic' displays. Although reported as a breakthrough for glasses free 3D mobile displays, the scientific team behind the technology claim that due to graphene's strength, there is no limit for scaling up to larger displays - i.e. 'holographic' tvs.
This, the team says, could one day revolutionise displays -- with the most obvious implications in mobile technology and wearable technology. It could also be used for holographic anti-counterfeit tags, security labels, and personal identification.
This makes sense for a first practical application, too: currently, the technology has only been used to produce holographic images up to one centimetre in size. Li and Gu note, however, that there is no limit to its scalability, thanks to graphene's mechanical strength.
However, a reader in the comments section underneath the article urges caution - again the term 'holographic' is being used here to refer to 2D displays that create the illusion of a three dimensional display, rather than a Star Wars type holographic projection.
I'm so sorry to disappoint but unfortunately this is a misinterpretation of the paper..
It's a common misinterpretation of "holography". Traditional holographic images have absolutely nothing to do with the science fiction idea of "holograms" and what are referred to as "holograms" in the movies. This scientific paper uses the traditional meaning of holograms.
I'd suggest anyone reading this to be alert of this misconception next time when you hear the term "hologram" or "holographic images/imaging"..
In nearly all cases, these terms are used in either of these three contexts: experts talking about traditional holograms, marketeers stretching the term to create interest in a 3D illusion product, and science fiction films referencing what in truth are open air 3D projections. Obviously these are very different, and the latter is still very much science fiction (except for one comparatively primitive Aerial 3D voxel display created by Aerial Burton in Japan).
Again, the holography talked about in this paper is traditional holography, the original meaning. It's the same thing you sometimes see on those 3D postcards, drinking cups for kids and flippos. The kind of hologram that can also be found on modern money, passports and other security objects that need verification of genuinity.
