Alphanumeric LED Displays
Alphanumeric LED Displays are display devices that show the information in the form of characters (numbers or alphabets). LEDs are used as the light source. Generally there are either 36 (alphabets 'A to Z' + numbers '0 to 9') or 62 (alphabets 'A to Z' + small case alphabets 'a to z' + numbers '0-9') alphanumeric characters which get displayed.
