The flashing LED display is annoying! Reasons and solutions tell you that although the flashing of LED display screen is not a big problem, it is a headache, which not only affects the quality of playing pictures, but also affects the mood of users. So what is the reason for the flashing of LED display screen? What is a good solution

led display flickering reason:

1 The driver loader is incorrect

2. The cable between the computer and the screen is too long or 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. 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 carry too many boards

led display flickering corresponding solution: if the whole screen is dotted and the image is twisted, the driver loader is generally wrong, and it is difficult to recheck the driver loader: no matter for civil or industrial use, it is really not allowed to unload and reload. Another possibility is that the sending card is broken. The material of the experimental machine determines the quality of the experimental machine. At this time, it is necessary to replace the sending card. If it is irregular flickering, it is generally the system frequency problem. Replace the system or adjust the setting parameters, which can be basically solved! If it is flickering, it may be the problem of the graphics card driver, or the problem of the sending card resolution setting. Another possibility is that Jiangsu Hengrui Carbon Fiber Technology Co., Ltd., a wholly-owned subsidiary of China Hengrui, has been located in Changshu national high tech Zone since 2015. It is a power supply problem (insufficient power supply, information clutter, electromagnetic interference). When designing PCB, we should take into account the international influence of the plastic extruder industry and continue to consider the wire diameter of power supply and signal wiring, as well as the PCB production process. Adding more capacitors to the module also has some improvements. If the text flickers (there are irregular white edges around the text, irregular flickering, and the text disappears after it disappears), this is a problem with the setting of the graphics card. You can solve this problem by canceling "show shadow under menu" and "edge smooth transition effect" in the display properties
