which would look like the figure given below.ħ-Segment Display Segments for all Numbersĭisplay combination of decimal numbers is given below.ĭigit 1: to display the digit 1 we need to turn on the segments b, c. Suppose we want to display digit ‘0’, in order to display 0, we need to turn on “a”, “b”, “c”, “d”, “e”, “f”. We assume common cathode LED segment as our example. Each of the pins will illuminate the specific segment only. Working of 7-Segment Display (LED & LCD) Circuitħ LED segments of the display and their pins are “ a”, “b”, “c”, “d”, “e”, “f” & “g” as shown in the figure given below. Related Post: Seven Segment Display: 7-Segment Display Types, Working & Applications.To illuminate any of the LED segments we need to provide logic ‘0’ to it. This terminal should be connected with Vcc or logic ‘1’ during its operation. The type of 7-Segment display in which all the anode terminals of 7 LEDs are connected together to form common anode terminal. To illuminate any LED of the display, you need to supply logic ‘1’ to its corresponding input pin. It should be connected to GND or logic ‘0’ during its operation. In such type of 7-segment display, all the cathodes of the 7 LEDs are connected together to form a common terminal. There are two types of 7-Segment displays.
