ABSTRACT:
A multibillboard system has a matrix of display monitors for displaying an image on a single screen. Electric energy from a power supply is supplied through a main power supply switch to the display monitors. In response to a power-on remote control signal, the electric energy from the main power supply switch is supplied to the display monitors to energize them successively with respective different time delays. Since the display monitors are energized successively, not simultaneously, any rush current flowing to the multibillboard system is reduced when the multibillboard system is turned on.
