The 7-segment screen, also written as "seven segment display", is made up of seven LEDs (hence its name) organized in a rectangular fashion as shown. Each of those seven LEDs is known as a segment because when illuminated the section forms a portion of a numerical digit (both Decimal and Hex) to be exhibited. An extra 8th LED is sometimes used within the exact same package thus permitting the indication of a decimal point, (DP) when two or more 7-segment displays are connected with each other to display amounts greater than ten.
Each of the seven LEDs in the screen is given a positional segment being attracted out of the package that was rectangular. These separately LED pins are tagged from a via to gram representing every LED. The LED pins are attached and wired to make a pin.
The common anode display is called CA display. In this type the common pin on the 7-segment display is connected to each of the eight Anode pins of the LEDs. So In order to produce this kind of seven segment display to function we must connect he Com snare to the Vcc (+5V typically) and ground the essential segment snare to flip it on.
