These kinds of displays can be found in calculators, watches, microwaves, almost any display that needs to portray numerical information. The convention for naming the seven segments that make up the display is as shown in the diagram above, from A to G. Lighting these segments in various combinations will enable you to display a particular number, or even some alphabetical characters.
7 segment displays come in one of two combinations: it could be a common anode connection in which all the anodes of the constituent segments are connected together; or it could be connected in a common cathode connection in which all the cathodes are connected together.
