发明名称 ENHANCED MODULAR MESSAGE BOARD
摘要 The present invention is a modular electronic sign having a plurality of display units (12) assembled on a mounting track (14) and connected to a sign controller (18). Each display unit (12) has a circuit board (20) having a plurality of light emitting diodes (74) arranged in a pattern thereon. A~ microprocessor (240) in each display unit (12) is in communication with the sign controller (18) and adjacent display units (12). Each display unit (12) 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 (442) mechanically connect the display units to the mounting track. Each display unit is mountable to the mounting track either horizontally or vertically.
