Scientists have created a 3D display that could mimic the Princess Leia hologram in Star Wars – even on mobile phonesScientists have created a glasses-free, 3D display that could mimic the famous hologram projection of Princess Leia in the original 1977 Star Wars film.The display is small and light enough to work on mobile phones, and produces images that appear in 3D even when viewed from different angles, the scientists said.To make the device, researchers at Hewlett-Packard Labs in Palo Alto, California, built a transparent screen with tiny light emitting diodes (LEDs) around the edges.
