Propeller LED Display

Abstract: Conventional methods of displaying images are by using LCD display or LED board. Propeller display is a special type of circular display that project an image as if the images are floating in the air. This project was started with a simple principle which is frequently happening in our day today life, which is Persistence of Vision (POV). Whenever the light from an image strikes on the retina, the eye retains the impression of that light for a particular fraction of seconds (1/16th) depending on the brightness of the image even after the image has been removed from the human sight. Most of the existing LED displays consumes large amount of energy due to more number of LEDs used. In the present work virtual displays are used in order to reduce the number of LEDs. The propeller is subjected to rotate above 1000rpm to obtain virtual display.
