New Materials Could Make Star Wars-Style 3D Screens

Everyone’s favorite wonder material, graphene, could soon create realistic 3D screens for mobile devices and smartphones. Whereas most 3D displays have thus far depended on fancy glasses or, in a last resort, parallax barriers that simulate 3D in the same way those gaudy pictures of waterfalls and winking ladies simulate movement.

Scientists at Swinburne University, however, are working on a 3D display that uses a graphene mesh and lasers to literally “float” an image over the screen, Princess Leia-stlye.

The system “uses graphene oxide and complex laser physics to create a pop-up floating display without the need for 3D glasses.” My changing the refractive index of the screen you can create 3D effects that are beyond anything we’ve seen.

“If you can change the refractive index you can create lots of optical effects,” said Director of Swinburne’s Centre for Micro-Photonics, Professor Min Gu.

Don’t look for “Help me Obiwan Kenobi”-style FaceTime any time soon, however. The technology is still very nascent and will require more research to move it into the commercial realm.
