LED Displays

 

  
 

LED displays are packages of many LEDs arranged in a pattern. There are many types of LED display and a supplier's catalogue should be consulted for the pin connections. Common Anode (SA) with all the LED anodes connected together and Common Cathode (SC) with all the cathodes connected together. Letters a-g refer to the 7 segments, A/C is the common anode or cathode as appropriate (on 2 pins). Note that some pins are not present (NP) but their position is still numbered

LED Displays use LED technology, which stands for Light Emitting Diodes. LED technology does not waste energy. For this reasons, LED technology is more and more popular in the world. LED offers a wide range of flexibility. It allows operator to make rapid changes with the remote location.

LED Displays are connected in different way. LED Displays can be connected to a PC via serial port, USB port. It can also be connected to the fiber optics cables, modems and even pages. In networking technology, LED Displays are controlled by LAN-WAN also.

LEDs are available in red, orange, amber, yellow, green, blue and white. Blue and white LEDs are much more expensive than the other colours.

The semiconductor material determines the colour of an LED, not by the colouring of the 'package' (the plastic body). LEDs of all colours are available in uncolored packages which may be diffused (milky) or clear (often described as 'water clear'). The colored packages are also available as diffused (the standard type) or transparent.
