Although the LED full-color display flicker is not a big problem, but it is a headache, not only affects the quality of the broadcast screen, but also affects the user's mood, so what is the cause of LED full-color display flicker? And what is a good solution? The following is a joint Chengfa Group technical engineers to share some information, take a look!


LED full-color display flickering causes:

       1. Driver loading program is not right

       2. Between the computer and the screen Hu network cable is too long or network cable failure

       3. Sending card is bad

       4. Control card is bad, check the control card on the small light is bright? If not, it is bad.

       5. Power supply and control card between the connecting wire is short-circuited.

       6. The output voltage and current of the power supply is not stable, and the power supply with the control card should not take too many boards.


LED full-color display flicker corresponding to the solution:


If the whole screen flower point, figure and shadow new move, generally is the driver loading program is not right, re-check the driver loading program, can not be uninstalled and re-installed!


There is a possibility that the sender card is bad, then you need to replace the sender card!


If the flickering is irregular, it is generally a system frequency problem. Replace the system, or adjust the setup parameters, basically can be solved!


If it is a blinking state of stars and dots, it may be a video card driver problem, it may also be a problem with the resolution settings of the sending card.


Another possibility, is the power supply problem (power supply is not enough, information clutter, electromagnetic interference), the design of the PCB should be more consideration of the power supply and signal alignment of the wire diameter, as well as the PCB production process. Adding a few more capacitors on the module also has some improvement.


If accompanied by text flicker (text around an irregular white edge, irregular flicker, text disappears after the disappearance of the disappearance), this is the graphics card settings, in the display properties to cancel the “menu under the display of the invisible shadow”, “edge of the smooth transition effect”. Can solve such problems.


The above is the LED full-color display flickering causes, and LED full-color display flickering solution, I hope to help you.
