1results about How to "Reduce transmission error rate" patented technology

The application relates to a display screen control system and a display screen, the system comprising a sending card, N+1 receiving card groups and N distribution cards, wherein N is a positive integer; the sending card comprises a first data interface and a second data interface; the N distribution cards are connected in sequence in cascade, and a first-stage distribution card is connected with the first data interface of the sending card; a first receiving card group is connected with the second data interface of the sending card; and the remaining N receiving card groups are connected with the N distribution cards in one-to-one correspondence. In the system, the distribution cards are connected in cascade with the sending card in a specific mode, the number of the interfaces of the sending card is reduced, wiring is simpler, and the installation complexity and difficulty are reduced. Further, the distribution cards are connected in sequence in cascade to form an orderly link, transmission confusion and interference caused by complex wiring are avoided, signal attenuation and noise are reduced, data is stably and accurately transmitted, and the system stability is enhanced.
