If you have been waiting for some time for a real innovation for the screens that display images on smartphones or computers, well a technology called JOLED comes to prove to us that there are still areas in which willing companies can seriously innovate in terms of the developed technology for users worldwide.
In the video clip below you can see a screen that levitates, it being created with the help of JOLED< technology that could be popular in the future. Unlike classic screens, here we are talking about the use of electric current and sounds to display images in the open air without a classic screen being used in this sense by the creators of the technology.
Developed by researchers from the universities of Sussex and Bristol, JOLED technology allows the use of acoustic waves and electric force fields to create this screen.
Researchers at the Universities of Sussex and Bristol have used sound waves to lift many tiny objects at once before spinning and flipping them using electric force fields. The objects visible to the human eye are formed with the help of nanoparticles held in place, but also in the air, using the techniques presented above.
These nanoparticles are in the form of spheres that are held in the air using utrasonic speakers that create a high-intensity sound that cannot be heard by the human ear, but which is strong enough to hold objects in the air and move them to it shows us that technology is possible.
"The pixels are levitated using a series of miniature ultrasound speakers that create high-pitched and high-intensity soundwaves that are inaudible but forceful enough to hold the spheres in place. This opens up a whole new design space, where computer and mobile displays extend into the 3D space above the screen. We've created displays in mid-air that are free-floating, where each pixel in the display can be rotated on the spot to show different colors and images."
