 The LEDs are spaced 6 holes apart, both horizontally and vertically. All of the cathode leads in a column are common and all of the anode leads in a row are common. To light up a single LED, you provide a signal to the row and open a transistor to allow the current to flow to ground through the selected column. By providing power to only one column at a time and refreshing the entire display about 120 times per second, you get the illusion of the entire display being lit at once.
