  2. Outline • Introduction to Dot-Matrix Display • Product Specification • Circuit Connection Results

  3. Introduction to Dot-Matrix Display

  4. Introduction to Dot-Matrix Display • 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.

  5. 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.
