With the increasing popularity of LED full-color display market, everyone has more and more knowledge of led display screens. Colorful large screens can be seen everywhere on the street, but occasionally screen flicker or other problems may occur. Talk about LED display flashing today!
Many people may not know that the LED display keeps flickering, which means that it affects the display effect. Flicker not only affects the quality of the playback picture, but also affects the mood of the audience. What causes the LED display to flicker? How do you troubleshoot? The following is a blue Haoxing Optoelectronics shared the cause of the display screen flashing and solutions.
The LED display flashes mainly due to the following 5 points:
1. The cable between the computer and the screen is too long, resulting in poor signal. Or network cable failures, such as poor contact of the network cable plug.
2. The connection between the power supply and the control card is short-circuited.
3. The power supply output voltage is not stable, and the power supply with the control card has too many cell boards.
4. The driver loader is wrong.
5. The sending card or control card is bad. Check if the small light on the control card is on. If it is off, it will be broken.
Flashing LED display solutions and methods:
If it is a bit flashing, it may be a graphics card driver problem, or it may be a sending card resolution setting problem.
Another possibility is that the sending card is broken. At this time, the sending card needs to be replaced.
If it is an irregular flash, it is generally a system frequency problem. Replace the system, or adjust the setting parameters, can basically solve!
Another possibility is the power supply problem (power supply insufficiency, information clutter, electromagnetic interference). When designing a PCB, consider the wire diameter of the power supply and signal traces, and the PCB manufacturing process. There are also some improvements in adding more capacitors to the module. If the accompanying text is flickering (there are irregular white borders around the text, irregular flashing, and disappearing after the text disappears), this is a problem with the graphics card setting. In the display properties, the "display shadows under the menu" is canceled, and the "edge smooth transition effect" is removed. . Can solve such problems.
If it is the entire screen to spend, the shadow of the shadow, generally the driver loader is wrong, re-check the driver loader, it is not reloading.
The above is the blue Hao star photoelectric to explain why the LED display screen flashes and solutions, if friends have better solutions or solutions to other problems, welcome everyone to "Tucao!" I hope you can ask more questions. If you have a problem with the LED display, you can contact the company to solve it!
