1. A driving system for driving a display wall, the display wall comprising M*N sub-display screens, and the driving system comprising:
a plurality of interface transforming units, configured to transform interfaces; and
a plurality of signal transforming units, electrically connected to the plurality of interface transforming units, configured to receive an external driving signal and send the external driving signal to the interface transforming units;
wherein each of the M*N sub-display screens comprises a sub-display screen driving circuit;
wherein the plurality of interface transforming units are further configured to receive the external driving signal from the signal transforming units and send the external driving signal to the sub-display screen driving circuit; and
wherein M is an integer greater than or equal to 1, and N is an integer greater than or equal to 1, and a number of the signal transforming units is lower than a number of the interface transforming units.
