Most of these displays uses stationary pixels to show arbitrary images or videos. Because the human eye retains a visual continuation of images with a succession of still frames, the video appears when the images are played by very quickly. The beauty of a persistence of vision (POV) display is that it uses the same optical illusion to display images. Much like how stationary displays use the optical illusion to display videos by playing multiple still frames rapidly, the POV display uses the same illusion to display an image by rendering each “row” of pixels individually very rapidly. The design of this multifunction display is based on the concept of persistence of vision with the utility of a fan. More importantly, the novelty of this POV display makes it a good conversation starter that can easily be assembled and customized. Using a single strip of mechanically rotating LEDs mounted on a fan blade, the display is able to give an illusion of an image to simulate an array of LEDs. As a result, a user is able to display anything from an analog clock to an image or short animation on the POV display.
