Analysis of the cause of the overlapping of subtitles on the indoor touch display screen 1. The subtitles are not properly debugged. 2. First check whether the power supply is loose and fall off. 3. Check whether the cable is firmly inserted. 4. Check the corresponding relationship between the module and the adapter board. 5. Adapter board output problem 2. Solution Check whether there are two texts in the edited subtitles that cause overlap. If the problem cannot be solved through steps 2 and 3, go directly to step 4. Because the wiring sequence of the adapter board and the module row are in a one-to-one correspondence, it is found that the modules just start from the fourth row, and there is no one-to-one correspondence. The 4-row module is connected to the 5th pin of the adapter board, and the subsequent modules can be deduced by analogy to restore the connection relationship. Steps 2, 3, and 4 are all confirmed that there is no problem, but the font overlap phenomenon is still not solved, then go to step 5 to adjust the output of the board. During the first use of the LED electronic display screen, there will be overlap phenomenon, follow steps 1, 2, 3, 4, and 5 to check; after a period of use, Shanghai touch display shows overlap phenomenon, follow steps 2, 3, and 5 to check; still can’t To solve the problem, contact the manufacturer or service provider.
