Specifically, a complete display screen system includes: video source-transmitting card-receiving card-hub board-lamp panel. If the loading process of the display system program is as follows: the FPGA adopts a JTAG passive loading method, the FPGA needs to be loaded through an external MCU, and the FPGA program is stored in an internal RAM, so that the display screen system automatically disappears after power failure and needs to be reloaded after next power-on, and the program needs to be loaded every power-on. In the embodiment, the single chip microcomputer is arranged on the hub board, and the single chip microcomputer identifies the types of different lamp panels through hardware design, and further correspondingly sends the types of the different lamp panels to different lamp panel programs of the receiving card according to the lamp panel types so as to realize the purpose of automatically identifying and loading programs by the single chip microcomputer. The singlechip recognizes different lamp panels through hardware connection, and then sends a program preset in the singlechip to the receiving card MCU, and the receiving card MCU loads the program to the receiving card FPGA.

Meanwhile, assuming that four lamp panels are marked by adopting a 2-pin decoding mode, then, a variable is declared in the single chip microcomputer program, and the value range is 1,2,3 and 4. The lamp panel type can be known by judging the level of the I/O port to update the variable during each power-on, and then different storage entry addresses can be found through the values of different variables, so that the corresponding program can be further determined. It should be noted that, the single chip microcomputer writes in the storage address entry of the lamp panel program in advance, associates the value of the variable with the value of the storage address entry in a variable declaration manner, and determines the value of the level marker as the value of the variable. If 4 lamp panels are provided, four groups of programs are written into the memory in sequence, the occupation sizes of the four groups of programs are known, and then the entry addresses, occupation ranges and ending addresses of the four groups of programs are known.
