Cause Analysis and Solution of LED Display Flickering

LED display flickering solution ideas and methods:

1. If the whole screen is dotted, and the picture and shadow buttons are moving, it is generally because the driver loading program is wrong. Check the driver loading program again, and uninstall and reinstall it. 2. Another possibility is that the sending card is broken, and the sending card needs to be replaced at this time. 3. If it is irregular flickering, it is generally a system frequency problem. Replacing the system or adjusting the setting parameters can basically solve the problem! 4. If it is blinking, it may be a problem with the graphics card driver, or it may be a problem with the resolution setting of the sending card. Another possibility is the power supply problem (insufficient power supply, information clutter, electromagnetic interference). When designing the PCB, more consideration should be given to the wire diameter of the power supply and signal traces, as well as the PCB production process. Adding a few more capacitors to the module has also improved. If it is accompanied by text flickering (there are irregular white borders around the text, irregular flickering, and the text disappears after disappearing), this is a problem with the graphics card settings. In the display properties, cancel "Show hidden shadows under the menu" and "Edge smooth transition effect" .
