LED display screen and method for updating configuration thereof, receiving card and display module

Abstract

A method for updating and configuring an LED display screen, a receiving card, an LED display module, and an LED display screen, the method comprising: detecting that the receiving card is powered on, reading the stored identity authentication data of the receiving card, and verifying the receiving card Whether it has been replaced; when the receiving card is confirmed to be replaced, output the configuration parameters stored in the memory to the receiving card and update the configuration parameters of the receiving card; detect that the LED display module is powered on, and then read the display identity authentication data of the LED display module , and verify whether the LED display module is replaced; when confirming that the LED display module is replaced, output the correction data of the LED display module to the receiving card; this embodiment updates the receiving card and / or the LED display module The status is detected and the data is automatically corrected, so that the display can return to normal video transmission in a short time after the receiving card and / or LED display module is updated, saving the time and cost of joint video debugging of the display.

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...
