The number of pixels in the screen with the advent of HD-TV market has become a source of heated discussion on the forums . In this regard, an experimental technology at the University of Sussex is particularly interesting: it is called JOLED and is the basis for a screen with a “resolution” in the 7 × 6 voxels. Moreover, each voxel is a miniature multi-colored sphere, each of which hangs in the air thanks to a set of ultrasonic speakers, “creating high-pitched and high-intensity sound waves do not create sounds, but powerful enough to hold the spheres.”
This allows you to keep the so-called JANUS objects in the air, but make them in certain moments to rotate and display a variety of colors allows something else entirely. The key point in the rotation areas is the fact that they are coated with titanium dioxide. Thus, when exposed to an electric field spheres begin to rotate. “ JOLED could be something like a floating display with electronic ink, which can also change color,” – said the researcher Deepak Sahu (Deepak Sahoo)
However, it is unlikely in the near future, technology will become available for everyday use. The University has suggested that it can help in many research projects the Disney and can also be used in commerce and tourism. With JOLED, for example, could show changes in carbon emission structure or jumps in exchange rates.
“We want to find ways to use this display for the offering of on-demand media,” – said the representative of the University of Sussex Sriram Subramanian (Sriram Subramanian). “screen will appear to the user to show the media, and when the video ends, the objects that form the display, fall to the ground.”
Researchers hope to increase the pixel density of its technology and its number of displayed colors. The team will demonstrate JOLED-screen on the ACM Symposium on User Interface and Technology, which will be held in Japan next week.
