Hi,
I would like to know how these Chinese led sign board is made.
1. How many rows of shift registers are used in a led board.?
2. Whether I can connect ONBON LED CONTROLLER with my home made led board with one set row of shift registers?
For these instances, where the information is very scarce, the best approach is to contact the vendor or vendors directly, and ask the exact same question.
I do not know for RGB model, but for single color 16 x 32 dot chinese led modul there is 16 pcs of 74hc595 (1/4 refresh). Each panel have 74hc245 buffer on data, clk, latch and enable line. There is one NOT gate, i think on enable line, hc138 decoder and 8 pcs dual p-channel fet transistors in SOP8 package for driving rows
