The principle of LED lattice screen is a simple 8X8 lattice as an example. It is composed of 64 leds, and each LED is placed at the intersection of row and column lines. When a corresponding row is set to level 1, and a column is set to level 0, the corresponding diode will light up. To light the first dot, pin 9 connects to a high level and pin 13 connects to a low level, then the first dot will light up. If the first row is lit up, pin 9 connects to a high level, and (13, 3, 4, 10, 6, 11,15,16) these pins connect to a low level, then the first row will light up. If the first column is lit up, pin 13 connects to a low level, and (9, 14, 8, 12, 1, 7, 2, 5) on the high level, then the first column will light up.
