You can read
an entry on Charlieplexing in Wikipedia. I quote:
"Much like standard multiplexed displays, all the cathodes of any particular digit are connected together to a single I/O pin which remains low. Much like standard multiplexed displays, each anode of each LED of a particular digit is tied to the current-limiting resistor of a different I/O pin.
