Flip-Disc or Flip-Dot -: Also known as reflective Disk Matrix Displays. These displays consist of a matrix of circular, square or rectangular elements that are reflective on one side and matte black on the other. An electromagnetic current rotates the elements to display either the black or reflective side, with the reflective elements forming to create the letters and therefore the message. The most common color of the reflective side is yellow. A flip dot display is a power driven display which can be programmed with many different configurations of flip dots to form different route displays. The driver can electronically select the required route for display.
