How to solve the problem that the LED display cannot load images?

2022/08/31

    In the process of using the LED display screen, if there is often a phenomenon that the image cannot be loaded, then follow the processing method below to exclude the black screen of the LED display screen.

    First, check whether the jumper cap of LED display screen is loose or falling off; If the jumper cap is not loose, make sure that the jumper cap is in the correct direction. Check and confirm that the serial port line used to connect the controller is a straight line, not a cross line. Check and confirm that the serial port connecting wire is intact and there is no looseness or falling off at both ends.

   Select the correct product model, correct transmission mode, correct serial port number and correct baud rate according to the LED display control software and the control card selected by yourself, and correctly set the address bit and baud rate on the control system hardware according to the dial switch diagram provided in the software.

   Ensure that the LED display control system hardware is properly powered on. If it still fails to load after the above inspection and correction, please use a multimeter to measure whether the serial port of the connected computer or control system hardware is damaged. To confirm whether it should be returned to the computer manufacturer or the control system hardware should be returned for testing.

   In many cases, the reason for the black screen of LED display screen is caused by improper operation in the process of use. Of course, there are also reasons for the LED display screen itself, but the probability is relatively small.
