Internal structure diagram of 8x8 LED dot matrix single color row common anode module

8x8 LED dot matrix common anode module internal circuit diagram The following figure is an internal structure diagram of an 8x8 LED dot matrix single color row common anode module. Its single point operating voltage Uf is 1.8 V, and the forward current IF is 8~10 mA. When a certain row line is high and a certain column line is low, the point where its rows and columns cross is lit; when a certain column line is high, the point where its rows and columns cross is dark; when a certain row line is low When the level is high, no matter what the column line is, all the points corresponding to this row are dark.
