Although the LED display flashing is not a big problem, it is a headache. It not only affects the quality of the playback picture, but also affects the user's mood. What is the cause of the LED display flickering ? What good solution ? ? Here is some of the information technology group of engineers to share, take a look.
　　 LED display flashing reason:
1. The driver loader is wrong.
2. The Hu cable is too long or the cable is faulty between the computer and the screen.
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 is not bright, it will be broken.
5. Is the cable between the power supply and the control card shorted.
6. The output voltage of the power supply is unstable, and the power supply with the control card should not carry too many boards.
　　 The LED display flashes correspondingly to the solution: (http://)
If it is the whole screen, the picture is moving, it is generally the driver loader is wrong, re-check the driver loader, it is not possible to uninstall and reload
Another possibility is that the sending card is broken. At this time, the sending card needs to be replaced.
If it is irregular flashing, it is usually a system frequency problem. Replacing the system, or adjusting the setting parameters, can basically be solved !
If it is a flashing state of the stars, there may be a problem with the graphics card driver, or it may be a problem with the resolution of the sending card.
Another possibility is the power supply problem ( insufficient power supply, information clutter, electromagnetic interference ) . When designing the PCB , consider the wire diameter of the power supply and signal wiring, and the PCB production process. There are also some improvements in adding more capacitors to the module.
If the text is flashing ( there are irregular white edges around the text, irregular flashes, and the text disappears after disappearing ) , this is a problem with the graphics card setting. In the display properties, cancel " Show hidden under menu " , " Edge smooth transition effect " . Can solve such problems.
The above is the reason for the LED display flashing, and the LED display flashing solution, I hope to help everyone.
