LED display flickering solution
Although the LED 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 display flicker? And what is a good solution?
LED display flickering causes:
1. Driver loading program is not right.
2. The network cable between the computer and the screen is too long or network cable failure.
3. Send a bad card.
4. control card is bad, check the control card on the small light on the light, if not on the bad. 5.
5. the power supply and the control card between the connecting wire is short-circuited.
6. the output voltage of the power supply
Current is not stable, with the control card power supply do not take too many boards.
LED display flickering corresponding to the solution: If the whole screen flower point, shadow twisting, generally 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 it is irregular flickering, it is generally a system frequency problem. Replace the system, or adjust the setup parameters, basically can be solved!
If it is a star blinking state, it may be the graphics card driver
Problems, 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. Add a few more capacitors on the module also has some improvement.
If accompanied by text flicker (text around the irregular white edges, 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”, you can solve these types of This is the problem of graphics card settings.
