This application discloses a configuration update method for an LED display screen, a receiver card, an LED display module, and an LED display screen. The method includes: (S) when it is detected that a receiver card is powered on, reading storage identity authentication data of the receiver card, and verifying whether the receiver card has been replaced; (S) when it is determined that the receiver card has been replaced, outputting a configuration parameter stored in a memory to the receiver card, to update a configuration parameter of the receiver card; (S) 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 the LED display module has been replaced; and (S) when it is determined that the LED display module has been replaced, outputting correction data of the LED display module to the receiver card.

Configuration update method for LED display screen, receiver card, LED display module, and LED display screen

An LED display driven by a dual-negative-voltage power supply is provided. The LED display includes a power supply interface and a display module. The power supply interface includes a first electrode, a second electrode, and a third electrode. The display module includes a substrate, the substrate is provided with a connection terminal having a first port, a second port, and a third port. The first electrode is coupled with the first port via a first wiring harness. The second electrode is coupled with the second port via a second wiring harness. The third electrode is coupled with the third port via a third wiring harness. A potential difference between the first electrode and the second electrode provides a first voltage. A potential difference between the first electrode and the third electrode provides a second voltage. The display module is configured to be powered with the first and second voltages.
