The present invention is a modular electronic sign having a plurality of display units assembled on a mounting track and connected to a sign controller. Each display unit has a circuit board having a plurality of light emitting diodes arranged in a pattern thereon. A microprocessor in each display unit is in communication with the sign controller and adjacent display units. Each display unit is hermetically sealed to avoid a separate enclosure for the modular sign. A plurality of clips are used to electrically connect the display units to power and communications conductors. A plurality of compression clips mechanically connect the display units to the mounting track. Each display unit is mountable to the mounting track either horizontally or vertically.
