Claim 5:
6. The LED display system according to claim 5, wherein in each stage of the plurality of driving circuits, the comparison and selection unit comprises:
a comparator, which is coupled to the communication unit to receive the parameter value and the identity number corresponding to that stage of the plurality of driving circuits, and configured to provide the comparison result obtained by comparing the parameter value and the identify number corresponding to that stage of the plurality of driving circuits;
a selector, having a first input terminal coupled with the inverter to receive the inverted clock signal, a second input terminal receiving the clock signal of that stage of the plurality of driving circuits, a control terminal coupled with an output terminal of the comparator to receive the comparison result, and an output terminal for outputting the inverted clock signal or the clock signal of that stage of the plurality of driving circuits to a next stage of the plurality of driving circuits.
