You explained great, thank you. In LED screen installations, in some cases, the lines of the pixels break in the card and give a worm error due to this. Although the pixels are solid, that line of the circuit can break due to voltage. A new line is drawn to the relevant pixel with the help of a wire over the chip. Can you explain which chipset will draw the line from which leg for this new line. I explained it a bit complicated, but you know what I mean. Finally, it would be great if you could explain the functions of the chipsets and related chipsets, and which leg controls which line and its function.
I see what you mean. We call this phenomenon a caterpillar. The reason is that a lamp bead is damaged and the current leaks to other lamp beads. This is related to the PCB design and the scanning method we often say. The reason why the display screen can display images is that it displays each line at a high speed. Because it is very fast, we can see continuous images, which are actually displayed line by line, If a lamp bead in the row is damaged, a caterpillar will appear in the column where the lamp bead is located. To repair this problem, just find the damaged lamp bead and replace it. Now many driver chips have been eliminated, such as ICN2153+5958;
My friend you can check the ic which is blue or red simple short the r-ext resistors and one of the colour cluster is bright this is the true ic you find. Thanks
Maybe you bought too little, so they didn't give it away. Generally, there are 1% spare modules. If you only buy 10 square meters or 20 square meters, it is very likely that there will be no spare modules; you need to Buy;
maybe you can ask for led screen factory. because not easy buy from lamps factory. because they just sell to factory.each time maybe 1000000000.like that. Non retail
can be 39.37*9.84 feet; it's 10M*3M. also If your hands-on ability is strong, you can choose modules and frames to assemble by yourself, which is a common practice for low-end LED screen;
