What's the problem of LED electronic screen flickering all the time

Although LED electronic screen flicker is not a big problem, but it is a headache. It not only affects the quality of the playing picture, but also affects the mood of users. So what is the problem of LED electronic screen flickering all the time? What is a good solution?

The reason of LED electronic screen flickering:

1. The driver loader is incorrect.
2. The line between the computer and the screen is too long or the line is out of order.
3. The sending card is broken.
4. The control card is broken. Check whether the small light on the control card is on or not. If it is not on, it will be broken.
5. Is the connection between the power supply and the control card short-circuited?
6. The output voltage and current of the power supply are unstable. The power supply with control card should not carry too many boards.

The corresponding solution of LED electronic screen flicker: if the whole screen is dotted and the image is twisted, the driver loader is usually wrong. It is impossible to uninstall and reload the driver loader by re-checking the driver loader. Another possibility is that the sending card is broken, at this time it is necessary to replace the sending card.

If the scintillation is irregular, it is usually the system frequency problem. Replacing the system or adjusting the setting parameters can basically solve the problem.

If it is the blinking state of stars and dots, it may be the driving problem of graphics card, or the resolution setting problem of sending card. Another possibility is the problem of power supply (insufficient power supply, information clutter, electromagnetic interference). When designing PCB, we should consider the diameter of power supply and signal wiring, as well as the production process of PCB. Adding a few more capacitors to the module also has some improvements.

If the text flickers with the LED electronic screen (irregular white edges around the text, irregular flicker, text disappears after disappearance), this is a graphics card setup problem, which can be solved by canceling the "hidden shadow under the menu" and "smooth edge transition effect" in the display properties.
