     BACKGROUND 
     At present, in an application scenario where the number of screen bodies is large but a single screen body has few pixel points, such as a bamboo screen and a creative screen, transversal wiring is not allowed between the screen bodies, and therefore, the screen bodies are independent of each other. Each independent screen body comprises one display unit or a plurality of cascaded display units, and each independent screen body needs to be connected to an output interface, such as an output network port, of a system controller for loading.

     First Embodiment 
     Referring to  FIG.  1   , this figure is an architecture schematic diagram of an LED display screen applicable to a splitter provided in the first embodiment of the disclosure. The LED display screen  30  comprises, for example, a plurality of display units  31 . Each display unit  31  comprises, for example, an assembly controller  311  and an LED display assembly  313  electrically connected to the assembly controller  311 . The assembly controller  311  is configured to, for example, drive and control the LED display assembly  311  to display an image. The assembly controller  311  is, for example, a receiving card or a scanning card. The LED display assembly  313  is, for example, an LED lamp box. One display unit  31  comprises, for example, one assembly controller  311  and one LED display assembly  313  electrically connected to the assembly controller  311 . One or more display units  31  in the LED display screen  30  form multiple columns of mutually independent screen bodies, each independent screen body comprises, for example, one display unit  31  or a plurality of cascaded display units  31 , and each of the independent screen bodies needs to be connected to an output interface, for example, an output network port. Therefore, how many mutually independent screen bodies the LED display  30  has, at least the same number of output network ports are required to load the LED display screen  30 . The LED display screen  30  is, for example, a bamboo screen or a creative screen; however, the embodiments of the disclosure are not limited thereto. 
     Referring to  FIG.  2   , this figure is an architecture schematic diagram of the splitter provided in the first embodiment of the disclosure. The splitter  10  comprises, for example, a processor  11 , a master interface  13  electrically connected to the processor  11 , and a plurality of loading interfaces  15  electrically connected to the processor  11 . 
     Specifically, the processor  11  is configured to, for example, forward image data input from the master interface  13  to the plurality of loading interfaces  15 , and the plurality of loading interfaces  15 , for example, output the image data to the assembly controllers  311  of all the display units  31  connected to the loading interfaces  15 , respectively. The assembly controller  311  of each display unit  31  performs, according to its own sequence number, a capture operation on image data output by the loading interface  15  corresponding to itself so as to obtain its own image data, and the assembly controller  311  of each display unit  31  drives and controls, on the basis of its own image data, an LED display assembly  313  connected thereto to display an image. The sequence numbers of the assembly controllers of the first display units  31  (e.g., corresponding to the first row of display units  31  in  FIG.  1   ) respectively first loaded on the plurality of loading interfaces  15  of the splitter  10  are different from each other. 
     In one particular embodiment, the splitter  10  comprises, for example, a processor  11  and three loading interfaces  15  electrically connected to the processor  11 . The sequence numbers of the assembly controllers  311  of all the display units  31  loaded on the first loading interface  15  of the splitter  10  are 1, 2 and 3 in sequence; the sequence numbers of the assembly controllers  311  of the display units  31  loaded on the second loading interface  15  of the splitter  10  are 4 and 5 in sequence; and the sequence number of the assembly controller  311  of the display unit  31  loaded on the third loading interface  15  of the splitter  10  is 6. The assembly controller  311  of the first display unit  31  loaded on the first loading interface  15  of the splitter  10  captures, for example, according to its sequence number 1, the image data output by the first loading interface  15 . For a method for capturing the image data by the assembly controllers  311  of other display units  31 , reference may be made to the process, and details are not described herein again. 
     Referring to  FIG.  3   , in one embodiment, the processor  11  is further configured to perform a method for configuring display screen so as to determine a sequence number of an assembly controller  311  of each display unit  31  loaded on the plurality of loading interfaces  15  of the splitter  10 . The process in which the processor  11  performs the method for configuring display screen comprises, for example: 
     Step S 1 , an initial sequence packet is acquired, wherein the initial sorting packet comprises a splitter serial number data segment and a first module controller serial number data segment. The initial sorting packet includes, for example, a splitter serial number data segment and a first assembly controller serial number data segment. The content of the splitter serial number data segment represents a serial number of the splitter, for example, aa, and the content of the first assembly controller serial number data segment represents a serial number of the first assembly controller, for example, bb. 
     In one particular embodiment, the processor  11  acquires, for example, through the master interface  13 , the initial sequence packet. The initial sequence packet is, for example, 0×0100, wherein  01  is, for example, the splitter serial number data segment, and  00  is, for example, the first assembly controller serial number data segment. 
     Step S 2 , configuration parameters are acquired, wherein the configuration parameters include a serial number of the splitter  10 , serial numbers of a plurality of loading interfaces  15  of the splitter  10  and a serial number of an assembly controller  311  in the first display unit  31  loaded on each loading interface  15 . 
     In one embodiment, the processor  11  acquires, for example, through the master interface  13 , the configuration parameters. For example, there are a plurality of configuration parameters. The splitter serial number represents the serial number of the splitter  10 , for example, aa; the loading interface serial number represents the serial number of a loading interface  15  in the splitter  10 , for example, bb; and the serial number of the assembly controller  311  in the first display unit  31  loaded on the loading interface  15  is, for example, cc. The configuration parameter is, for example, 010307, which indicates, for example, that the serial number of the assembly controller  311  of the first display unit  31  loaded on the loading interface  15  with the loading interface serial number  03  of the splitter  10  with the splitter serial number  01  is  07 . 
     In one embodiment, the processor  11  acquires, through the master interface  13 , three different configuration parameters, for example, 010101, 010204 and 010308. For example, the first configuration parameter indicates that the serial number of the assembly controller  311  of the first display unit  31  under the loading interface  15  with the loading interface serial number 01 of the splitter  10  with the splitter serial number 01 is 01; the second configuration parameter indicates that the serial number of the assembly controller  311  of the first display unit  31  under the loading interface  15  with the loading interface serial number  02  of the splitter  10  with the splitter serial number 01 is 04; and the third configuration parameter indicates that the serial number of the assembly controller  311  of the first display unit  31  under the loading interface  15  with the loading interface serial number 03 of the splitter  10  with the splitter serial number 01 is 08. 
     The process in which the processor  11  determines the serial number of the assembly controller  31  of each display unit  30  according to set configuration parameters is provided. 
     Step S 3 , the content of the first assembly controller serial number data segment in the initial sequence packet acquired in step S 1  is updated according to the serial number of the assembly controller  311  in the first display unit  31  loaded on each of the loading interfaces  15  determined in step 2, so as to obtain a plurality of target sequence packets corresponding to the loading interfaces  15  respectively and output respective target sequence packets through the loading interfaces  15 , so that the assembly controllers  311  in all the display units  31  loaded on each of the loading interfaces  15  determine their own sequence numbers in sequence, the plurality of target sequence packets being different from each other. 
     In one particular embodiment, for example, in step S 2 , three configuration parameters, i.e., 010101, 010204 and 010308 are acquired, and for example, in step S 1 , the acquired initial sequence packet is 0×0100. The first assembly controller serial number data segment  00  of the initial sequence packet is updated according to the serial number  01  of the assembly controller in the first display unit of the first configuration parameter 010101, so as to obtain that the target sequence packet of the loading interface  15  with the loading interface serial number  01  of the splitter  10  with the splitter serial number 01 is 0×0101, and the target sequence packet 0×0101 is output to the assembly controller  311  in the first display unit  31  loaded on the loading interface  15  with the loading interface number  01  of the splitter  10  with the splitter serial number 01. The assembly controller  311  in the first display unit  31  obtains its own sequence number 01, and the assembly controller  311  in the first display unit  31  adds one to the first assembly controller serial number data segment in the target sequence packet to obtain an updated target sequence packet 0×0102, and deliver the updated target sequence packet to an assembly controller  311  in the second display unit  31  cascaded with the assembly controller  311  in the first display unit  31 . The assembly controller  311  in the second display unit  31  obtains its own sequence number  02 , and the assembly controller  311  in the second display unit  31  adds one to the first assembly controller serial number data segment in the target sequence packet to obtain an updated target sequence packet 0×0103 and continues to deliver same, until the assembly controllers  311  of all the display units  31  under the loading interface  15  with the loading interface serial number 01 of the splitter  10  with the splitter serial number  01  are all determined and obtain their own sequence numbers. The first assembly controller serial number data segment 00 of the initial sequence packet is updated according to the serial number  04  of the assembly controller in the first display unit of the second parameter packet 010204, so as to obtain that the target sequence packet of the loading interface  15  with the loading interface serial number  02  of the splitter  10  with the splitter serial number 01 is 0x0104, and the target sequence packet 0×0104 is output. The first assembly controller serial number data segment 00 of the initial sequence packet is updated according to the serial number 08 of the assembly controller in the first display unit of the third parameter packet 010308, so as to obtain that the target sequence packet of the loading interface  15  with the loading interface serial number  03  of the splitter  10  with the splitter serial number  01  is 0×0108, and the target sequence number 0×0108 is output. 
     Referring to  FIG.  3    again, in one embodiment, the processor  11  performs the method for configuring display screen, for example: 
     step S 4 , the content of the splitter serial number data segment in the initial sequence packet is updated, and the content of the first assembly controller serial number data segment is kept unchanged, so as to obtain a new initial sequence packet and deliver, through a slave interface of the splitter, same to a next-level splitter electrically connected to the slave interface. 
     In one particular embodiment, for example, when the slave interface  14  of the splitter  10  is connected to the master interface of another splitter, the processor  11  updates the content of the splitter serial number data segment in the initial sequence packet, for example, 0×0100, which is acquired in step S 1 , and the processor  11 , for example, adds one to the splitter serial number data segment to obtain a new initial sequence packet 0×0200; furthermore, the processor delivers the new initial sequence packet 0×0200 to another splitter through the slave interface  14 , and the processor of another splitter receives, for example, through the master interface of another splitter, the new initial sequence packet 0×0200. This process is step S 1  above. The processor of another splitter performs step S 2  and step S 3  so as to complete that the assembly controllers  311  of all the display units  31  loaded on the plurality of loading interfaces of another splitter determine their own sequence numbers, and details are not described herein again.
