Using a motor and some power trans-unit, LED string mounted on a printed circuit board are duly interfaced to a SoC . This displays some message and a clock timing taking advantage of persistence of vision . Without the single line of LEDs in space multiplexing mode if one would have to display a photo, number of LEDs as high as around 82,000 would have been used. Here the project uses only 360 LEDs. Thus material count, hardware requirement, brings the overall cost to very affordable price. The synchronizing is being implemented through software. AeroGram Displays is a new type of LED display in which it uses Persistence Of Vision(POV) as its principal. POV is a type of optical illusion, Persistence of vision (POV) refers to the phenomenon of the human eye in which an afterimage exists for a brief time. A POV display uses this phenomenon to recreate holograms using LED display .It creates the images in mid-air with a 1-Dimensional led Line and a motor which help it to take a 2- dimensional form. By using proper content we can make it look like 3D images and videos. Keyphrases: Digital hologram display, LED, POV Download PDFOpen PDF in browser |
