This paper explains the project which is a special kind of circular LED display. The Propeller Display is a linear array of light emitting diodes, rotating at a high angular velocity to generate a circular screen. With the help some mechanical assembly, LED count, hardware requirement, and hence overall cost is cut to very affordable price. Also, maintenance and repairing of the display is easy. All the synchronizing can be implemented through software. This project uses the principle of Persistence of Vision. The propeller display is mechanically scanned and displays the characters and symbols. It can be used anywhere and everywhere and the most amazing fact is its crystal clear display.
