A dot-matrix display is a display device used to display
information on machines, clocks and many other devices requiring a
simple display device of limited resolution. 4

LED Matrix It consists of a 2-D diode matrix with their
cathodes joined in columns and their anodes joined in rows (or vice
versa). By controlling the flow of electricity through each row and
column pair it is possible to control each LED individually. 5
