A modular messaging sign panel contains a plurality of LEDs coupled to a plurality of latched drivers. A microcontroller on the panel has a unique serial number permitting the panel to be selectively addressed by a host. The microcontroller receives serial data representing an image frame, selects the data intended for the panel in which it controls and clocks it out to the latched drivers along a single serial data line. Multiple panels can be connected to form a larger display panel system. Each panel has its own uniquely addressed microcontroller. A three wire connection couples the panel or display system to a computer and a power supply. A single jumper wire connects each modular panel together such that the data output from the computer is received by every microcontroller within the system in a parallel configuration. Accordingly, each microcontroller is receiving all the data outputted from the computer but only selects certain data for distribution to the latched drivers coupled to the LEDs on its particular panel based upon an ID match. Power and ground are supplied to a multi-panel system via power and ground rails of a frame structure upon which the panels are mounted.
