Compared with the LCD splicing screen, the full-color LED display has a much higher probability of bright lines and screen faults than the LCD splicing screen. However, in general, these small faults are easy to deal with, so the full-color LED display There are still many supporters. How to deal with the bright lines on the full-color LED display?

When detecting the bright line of the full-color LED display, turn on the power first and see if the indicator light of the control card is on; if it is not on, check whether there is a 5V power supply to see if the full-color LED display can display content. Display content, indicating that the display content function of the control card is good.
The detection of this step only proves that the control card itself is intact, and the software of the control card works well and needs to be checked. Next, use the control card software to find the control card. If you can find it, it means that the function of sending the content of the control card is good; if you can't find it, check whether the communication line is connected properly.
