1. An electronic messaging display sign including at least one modular panel, each at least one modular panel comprising:

  • a) an electrical circuit board;

    b) a plurality of lights coupled to said circuit board;

    c) a microcontroller coupled to said circuit board for receiving data from a master control and illuminating said plurality of lights through a driver element based on said data through a driver element, the microcontroller including a control mechanism and memory, the master control common to each of said at least one modular panel;

    d) a power source;

    e) a single serial data wire for connection to said at least one modular panel, the single serial data wire transmitting said data from said master control to said at least one modular panel to display a message on said electronic messaging display sign;

    f) the data received by said microcontroller of said at least one modular panel transmitted in frames; and

    g) the frames including character sets, picture data, animation, load frame data, frame display commands and frame manipulation commands.
