Although the flashing of LED electronic screen will not affect the lighting of LED electronic screen, it has seriously affected the user experience of customers. What is the reason for the flashing of LED electronic screen and what are the good ways to avoid this problem
Causes of LED electronic screen flashing:
1. The output voltage and current of the power supply are unstable. The power supply with control card should not carry too many boards.
2. The network cable between the computer and the screen is too long or the network cable is faulty.
3. Check whether the connecting wire between the power supply and the control card is short circuited.
4. The control card is broken. Check whether the small light on the control card is on? If it doesn’t light up, it’s broken.
5. The sending card is broken.
6.. The driver loader is incorrect.
Corresponding solutions for LED electronic screen flashing:
If the whole screen is dotted and the image is touched, the driver loader is generally wrong. Recheck the driver loader. It is really impossible to uninstall and reinstall.
Another possibility is that the sending card is broken. At this time, the sending card needs to be replaced.
If it is an irregular flicker, it is generally a system frequency problem. Replace the system or adjust the setting parameters, which can be basically solved!
If it is in the flickering state, it may be a problem with the graphics card driver or the resolution setting of the sending card.
Another possibility is the power supply problem (insufficient power supply, information clutter, electromagnetic interference). When designing PCB, we should consider the wire diameter of power supply and signal wiring and PCB production process. Adding more capacitors to the module also has some improvements.
If the text flickers (there are irregular white edges around the text, irregular flickering, and the text disappears after it disappears), this is a problem with the setting of the graphics card. In the display properties, cancel “show hidden shadow under menu” and “edge smooth transition effect”. Can solve such problems.
The above is the reason for the flashing of LED electronic screen, and the solution to the flashing of LED electronic screen. I hope it will be helpful to you.
