Although the LED full-color display flicker is not a big problem, it is a headache. It not only affects the quality of the playback picture, but also affects the mood of the user. So what is the cause of the LED full-color display flicker? Is there any good solution? The following is some information shared by the technical engineers of Lianchengfa Group. Let's take a look

LED full color display flashing reasons:

1. Incorrect driver loader
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 if the small light on the control card is on? If it doesn't light, it's broken.
5. Whether the connection between the power supply and the control card is short-circuited.
6. The output voltage and current of the power supply are unstable. Do not bring too many boards with the power supply with the control card.

LED full-color display flashing corresponding solution:

If the screen is full of dots and shadows, the driver loader is usually wrong. Check the driver loader again. Uninstall and reinstall it.
Another possibility is that the sending card is broken, and you need to replace the sending card at this time.
If the flicker is irregular, it is usually a system frequency problem. Changing the system or adjusting the setting parameters can basically be solved!
If it is a flickering state, it may be due to a problem with the driver of the graphics card or the resolution setting of the sending card.
Another possibility is the power supply problem (insufficient power supply, information clutter, and electromagnetic interference). When designing the PCB, consider the diameter of the power supply and signal traces, and the PCB production process. Adding a few more capacitors to the module has also improved.
If the text is flickering (with irregular white borders around the text, flickering irregularly, and the text disappears after disappearing), this is a problem with the graphics card settings. In the display properties, cancel "Show shadows under the menu" and "Edge smooth transition effect" . Can solve such problems.
