Classification: CPC G | IPC G

Claim 0:
1. A LED display system, comprising:
a control card, configured to output a plurality of clock signals and a plurality of data signals;
at least one driving circuit group, which is coupled with the control card, wherein each of the at least one driving circuit group comprises a plurality of driving circuits which are connected in cascade, and is configured to receive a corresponding one of the plurality of clock signals and a corresponding one of the plurality of data signals and transmit the corresponding one of the plurality of clock signals and the corresponding one of the plurality of data signals in the plurality of driving circuits, wherein in each of the at least one driving circuit group, at least one stage of the plurality of driving circuits each comprise an inverter which is configured to perform inverting processing on the corresponding one of the plurality of clock signals, which is received by that stage of the plurality of driving circuits, to obtain an inverted clock signal,
wherein the at least one stage of the plurality of driving circuits is each configured to output the corresponding one of the plurality of clock signals or the inverted clock signal selectively to a next stage of the plurality of driving circuits, according to a comparison result, obtained according to a parameter value and a corresponding identity number which are decoded from the corresponding one of the plurality of data signals received by that stage of the plurality of driving circuits.
