Novel LED display screen control system and dormancy method and awakening method thereof

The invention discloses a novel LED display screen control system which comprises a main control unit and a display module, and is characterized in that the main control unit comprises a main controlnetwork transformer, and the display module comprises a sub-control input network transformer and a sub-control output network transformer; the main control unit receives a dormancy signal, an awakening signal and a display control signal, and sends the dormancy signal, the awakening signal and the display control signal through the main control network transformer; the display module receives thedormancy signal, the awakening signal and the display control signal sent by the main control network transformer through the sub-control input network transformer; and the display module sends the dormancy signal, the awakening signal and the display control signal to the sub-control input network transformer of the next display module through the sub-control output network transformer. During dormancy, only the dormancy
