Although LED display flicker is not a big problem, it is a headache problem, which not only affects the quality of playing pictures, but also affects the mood of users. So what is the reason for LED display flicker? What are the good solutions?
LED is caused by flashing display screen
1. The driver loader is incorrect.
2. The network cable between the computer and the screen is too long or the network cable is faulty.
3. The sending card is broken.
4. The control card is broken. Check whether the small light on the control card is on. If it is not on, it will be broken.
5. Check whether the connecting wire between the power supply and the control card is short-circuited.
6. The output voltage and current of the power supply are unstable. The power supply with control card should not be equipped with too many boards.
Solutions for flashing led display
If it is a full-screen dot and the image is twisted, it is usually a driver loader error. Recheck the driver loader, but it can‘t be uninstalled or reinstalled.
Another possibility is that the sending card is broken and needs to be replaced.
If it is an irregular flicker, it is usually a problem of system frequency. It can be basically solved by replacing the system or adjusting the setting parameters! If it is flashing, it may be a graphics card driver problem, or it may be a sending card resolution setting problem. Another possibility is the power supply problem (insufficient power supply, information wave, electromagnetic interference). When designing a PCB, consider the wire diameter of the power supply and signal lines, and the PCB production process. Adding several capacitors on the module also has some improvements.
