How to solve the problem of overlapping LED display screen
The LED display screen may encounter many technical problems during the installation process or after it is put into use. Some may be caused by errors in the process of installing the connection lines, while others may be caused by improper settings or operation errors. Usually, as long as the static Come down and investigate carefully, the problem is likely to be solved by clearing it. This time, we will talk about how to troubleshoot the problem so that the screen can be displayed normally when the LED display screen has overlapping coverage.
The so-called LED display screen overlap means that the upper and lower lines of fonts or images overlap, or only part of them can be displayed normally, and the positions are uneven.
The solution is to first, check whether the power supply connection has any signs of loosening and falling off. Usually, unstable power supply is the most common problem that causes the failure of the LED display; secondly, check whether the cable is connected firmly; if the above two items are checked correctly, the problem is If it still exists, then we will continue to troubleshoot the failure of other components.
Connect each module in series, connect it to the adapter board, and then connect the adapter board to the control card, so that the problem can be easily found. Because the wiring sequence of the adapter board is in a one-to-one correspondence with the module rows, if the modules in the upper row and the modules in the lower row are connected in reverse, the displayed order will be disrupted. The normal situation should be one-to-one correspondence, so that the content of the screen can be displayed normally, so this is the reason for the overlapping of the screen. As long as the corresponding relationships are re-spliced one by one, everything will return to normal. If there is no problem with the adapter board after inspection, it means that there is a problem with the output of the adapter board.
Through the above analysis, we found that the reason for the so-called failure is actually caused by the failure of some details. Therefore, Easystar hereby reminds everyone that the display screen must be carefully checked for errors during installation and acceptance. , most of the time it’s not the quality of the display itself, so don’t worry too much.
