7 Segment LED Displays


The 7 segment display is found in many displays such as microwaves, lifts, ovens etc. It consists of 7 LEDs that have been combined into one case to make a convenient device for displaying numbers and some letters.

Displays come is a range of colours and brightness levels. Most come in super-bright and these are preferred so the display can be seen during the day. They are not much more expensive but give a much better illumination. All displays also come in COMMON CATHODE and COMMON ANODE. The COMMON CATHODE display has all the
cathodes of the LEDs tied together and connects to the pin that goes to the 0v rail. This is the most common type of display.


The Common Cathode and Common Anode displays are wired as shown below:

    Hi all,

    LED 7 segments, which is a way to driving your instrument and home appliance appearance better than others. Seven-segment displays can be packaged in a number of ways. Seven-segment displays can be constructed using any of a number of different technologies. The three most common methods are fluorescent displays, liquid-crystal displays, and LEDs. Thanks...
