Claim 4:
5. An LED display system, comprising:
a plurality of first display units, wherein each of the first display units comprises a first assembly controller and an LED display assembly electrically connected to the first assembly controller;
a first splitter, provided with a first processor and a first master interface, a slave interface and a plurality of first loading interfaces electrically connected to the first processor, wherein each of the first loading interfaces is configured to load one of the first display units or a plurality of cascaded first display units, and the first processor is configured to forward image data input from the first master interface to the plurality of first loading interfaces and the slave interface, so that the first assembly controller of each of the first display units performs, according to a sequence number of the assembly controller, a capture operation on image data output by the corresponding first loading interface to acquire image data of the assembly controller so as to drive and control the LED display assembly of the first display unit to display;
a plurality of second display units, wherein each of the second display units comprises a second assembly controller and an LED display assembly electrically connected to the second assembly controller; and
a second splitter, provided with a second processor and a second master interface and a plurality of second loading interfaces electrically connected to the second processor, wherein the second master interface is electrically connected to the slave interface of the first splitter, each of the second loading interfaces is configured to load one of the second display units or a plurality of cascaded second display units, and the second processor is configured to forward image data input from the second master interface to the plurality of second loading interfaces, so that the second assembly controller of each of the second display units performs, according to a sequence number of the assembly controller, a capture operation on image data output by the corresponding second loading interface to acquire its own image data so as to drive and control the LED display assembly of the second display unit to display,
wherein, the sequence numbers of the first assembly controllers of the first display units respectively first loaded by the plurality of first loading interfaces are different from each other, the sequence numbers of the second assembly controllers of the second display units respectively first loaded by the plurality of second loading interfaces are different from each other, and the sequence number of the first assembly controllers of the first display units respectively first loaded on the plurality of first loading interfaces are different from the sequence numbers of the second assembly controllers of the second display units respectively first loaded on the plurality of second loading interfaces.
