Could ‘Floating Pixels’ Become Real-World Holograms?

Scientists from at the Universities of Sussex and Bristol have developed floating pixels. These floating pixels use floating coloured spheres. Scientists actually want to turn the objects into floating pixels. So they used spheres that are suspended by acoustic waves.

These acoustic waves control those spheres using alternative electric force fields by using ultrasonic. After that, scientists paint the balls with contrasting faces. Those faces could be spun to show somewhat of an ‘image’ at 36 pixels.

According to scientists, this technology could produce viable holograms.

Dr. Deepak Sahoo, said, “The most exciting part of our project is that we can now demonstrate a fully functioning display. The display, which is made of a large collection of small objects that are levitating in mid-air. JOLED could be like having a floating e-ink display that can also change its shape.”

In other words, scientists now can make the display multi-colored and with high colour depth. Through this, they can show more intense colours.

Asier Marzo, research associate said, “Traditionally, we think of pixels as tiny colour-changing squares that are embedded into our screens. JOLED breaks that preconception by showing physical pixels that float in mid-air. In the future, we would like to see complex three-dimensional shapes made of touchable pixels that levitate in front of you.”

Professor Subramanian said, “We also want to examine ways in which such a display could be used to deliver media on-demand. A screen appears in front of the user to show the media and then the objects forming the display fall to the ground when the video finishes playing.”
