LED display screen, configuration updating method of LED display screen, receiving card and display module

Abstract

The invention discloses a method for updating configuration of an LED display screen, a receiving card, an LED display module and the LED display screen, and the method comprises the steps: detectingthat the receiving card is powered on, reading the storage identity authentication data of the receiving card, and verifying whether the receiving card is replaced or not; when it is confirmed that the receiving card is replaced, the configuration parameters stored in the memory are output to the receiving card, and the configuration parameters of the receiving card are updated; when it is detected that the LED display module is powered on, reading display identity authentication data of the LED display module, and verifying whether the LED display module is replaced or not; when it is confirmed that the LED display module is replaced, correction data of the LED display module are output to the receiving card; according to the embodiment of the invention, detection and automatic data correction are carried out on the update state of the receiving card and/or the LED display module, so that the display screen recovers to normal video transmission in a short time after the receiving cardand/or the LED display module is updated, and the video joint debugging time and cost of the display screen are saved.

Description

technical field [0001] The application belongs to the technical field of display screen control, and in particular relates to a method for updating configuration of an LED display screen, a receiving card, an LED display module and an LED display screen. Background technique [0002] With the rapid development of modern industrial technology, LED (Light Emitting Diode, light-emitting diode) displays have gradually been widely used in people's lives and industrial production processes; LED displays are not only simple to manufacture, but also can be used in various environments. Maintain normal work, and the LED display has the characteristics of high resolution, wide viewing range, long viewing distance, large area, and large impact. LED displays are usually used in outdoor advertising, commercial display, stage rental, data visualization, etc. field. In the full-color LED display industry, the display project is a semi-engineering project. The display box is produced in th...
