Wiring seven segment displays in multiplexed manner takes lots of connections. This means lots of wires and soldering and thus time consuming and error pron. Complexity increases if the displays are of big size like 4 inch height displays because general purpose PCBs of that size are not easily available. In this situation our PCB comes to rescue. This PCB have all the multiplexing connection done in tracks thus zero wiring and connection needs to be done. Just place the displays and solder.
