METHOD FOR CONFIGURATION UPDATING OF LED DISPLAY SCREEN, RECEIVING CARD, LED DISPLAY MODULE, AND LED DISPLAY SCREEN

摘要

Disclosed in the present application are a method applied to configuration updating of an LED display screen, a receiving card, an LED display module, and an LED display screen. The method comprises: (S201) when it is detected that a receiving card is powered on, reading stored identity authentication data of the receiving card, and verifying whether receiving card replacement is performed; (S202) when it is confirmed that receiving card replacement is performed, outputting configuration parameters stored in a memory to the receiving card, and updating the configuration parameters of the receiving card; (S203) when it is detected that an LED display module is powered on, reading display identity authentication data of the LED display module, and verifying whether LED display module replacement is performed; and (S204) when it is confirmed that LED display module replacement is performed, outputting corrected data of the LED display module to the receiving card. According to the present embodiments, the updating state detection and automatic data correction are performed on a receiving card and/or an LED display module, such that a display screen is restored to normal video transmission within a short period of time after the receiving card and/or the LED display module are/is updated, thereby saving on the time and cost of video joint debugging of the display screen.
