Internal structure diagram of 8x8 LED dot matrix monochrome line common anode module

8x8 LED dot matrix common anode module internal circuit diagram The following figure is an internal structure diagram of 8x8 LED dot matrix monochrome line common anode module, its single point working voltage Uf is 1.8 V, forward current IF is 8~10 mA. When a row line is high and a column line is low, the point where the row and column intersect is illuminated; and when one of the column lines is high, the point where the row and column intersect is dark; when a row line is low At the level, regardless of the column line, the points corresponding to this line are all dark.
