LED display flicker cause analysis and solution

Many people may not know that the LED display has been flickering, flickering not only affects the quality of the playback screen, but also affect the mood of the audience, resulting in LED display flickering causes what? And how to troubleshoot to solve? The following is the LED display manufacturers to share with you about the reasons for the display flicker and the solution.

LED display flickering reasons are mainly the following 5 points.

  1. The driver loading program is not right.
  2. The network cable between the computer and the screen is too long, resulting in too poor signal. Or network cable failure, such as poor contact with the crystal head of the network cable.
  3. Sending card or control card is bad, check whether the small light on the control card is on, if not, it is bad.
  4. power supply and control card between the connection line is short-circuited.
  5. The power supply output voltage and current is unstable, the power supply with control card with too many unit boards.

LED display flicker solution ideas and methods.

  1. If the whole screen is the point of flower, figure shadow new move, generally is the driver loading program is not right, re-check the driver loading program, it is not possible to uninstall and reinstall.
  2. There is a possibility that the transmitter card is bad, it is necessary to replace the transmitter card.
  3. If it is irregular flashing, generally the system frequency problem. Replace the system, or adjust the setting parameters, the basic solution!
  4. If the blinking state of the stars, it is possible that the graphics card driver problems, it is also possible to send the card resolution settings.
    Another possibility, is the power supply problems (power supply power supply is insufficient, information clutter, electromagnetic interference), the design of the PCB to give more consideration to the power supply and signal alignment line diameter, as well as PCB production process. Module on the addition of a few more capacitors also have some improvements. If accompanied by text flicker (text around the irregular white border, irregular flicker, the text disappears after disappearing), this is a graphics card settings problem, in the display properties to cancel the “menu display occlusion”, “edge smooth transition effect”.
