Propeller LED Display

Today, in the present era, energy is a crucial factor in designing the applications of display systems. Energy must be used in an efficient way. The methods used for displaying data usually in public use LCD display and dot-matrix LED display board. Propeller LED display is a device that displays data with least possible number of LEDs that appear as if they are suspended in the air. In this paper, the suspended image is formed due to the limitation of the human eye, i.e. because of an illusionary principle called the persistence of vision (POV). Actually the suspended images emerge by syncing LED's blink to form an image at a specific time and rate. The implementation for the display is done with an advanced RISC based Harvard microcontroller. Keywords- Persistence of vision (POV), propeller, ATmega328, Space Multiplexing
