As the LED display market becomes more and more popular, everyone knows more about LED displays. Large and colorful screens can be seen everywhere on the street, but occasionally screen flickering or other problems occur. Come today. Talk about the problem of flickering led display! Many people may not know that the LED display keeps flickering, which means that it affects the display effect. The flicker not only affects the quality of the playback picture, but also affects the mood of the audience. What are the reasons for the flickering of the LED display? How to troubleshoot and solve it? The following is LED The display manufacturer Liancheng shared with you the causes and solutions of the display flicker.   The main reasons for the flickering of the LED display are the following 5 points:    1. The network cable between the computer and the screen is too long, resulting in poor signal. Or the network cable is faulty, such as poor contact of the network cable crystal plug.   2. Whether the connection line between the power supply and the control card is short-circuited.   3. The output voltage and current of the power supply are unstable, and the power supply with control card has too many unit boards.   4. The driver loader is wrong.   5. The sending card or 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.   LED display flicker solution ideas and methods: If it is blinking, it may be a problem with the graphics card driver, or it may be a problem with the resolution setting of the sending card.     There is another possibility that the sending card is broken, and the sending card needs to be replaced at this time.   If it is irregular flicker, it is usually a system frequency problem. Replacing the system or adjusting the setting parameters can basically solve it!    Another possibility is the power supply problem (insufficient power supply, information clutter, electromagnetic interference). When designing the PCB, more consideration should be given to the diameter of the power supply and signal traces, as well as the PCB. Production Process. Adding a few more capacitors to the module also has some improvements. If it is accompanied by text flashing (irregular white borders around the text, irregular flashing, and the text disappears after it disappears), this is a problem with the graphics card settings. In the display properties, cancel the 'Display hidden shadow under the menu' and 'Smooth edge transition effect' . Can solve such problems. If the whole screen is fascinated and the picture is moving, it is usually because the driver loader is wrong. Check the driver loader again, it is impossible to uninstall and reinstall.   The above are the reasons and solutions for the flickering of the LED display. If there are any good solutions or other problems caused, welcome everyone to 'Tucao'! I hope everyone can ask more questions. If the LED display failure problem is adopted by this site, there will be rich rewards!
