Electronics are shrinking due to the demand for ever-smaller parts for our go-everywhere, do-everything mobile devices. Now the boffins at the Fraunhofer Institute in Germany have developed a miniature video projector no bigger than a sugar cube.

They’ve managed to include two out of the three lasers present in normal-sized projectors, which means that they can only display a limited number of colours at the moment.

While other projectors use millions of mirrors to project images on to a screen, this little one uses just one mirror that vibrates to deflect the beam of light from the laser.

At just 16mm thick and 9mm high, the projector is small enough to perhaps one day be incorporated into mobile phones and notebook computers.

Dr Peter Schreiber, one of the scientists involved in the project, said that it is even able to project on curved surfaces, like a dome, so it may find a home in certain niche applications.
