7 SEGMENT DISPLAY COMMON CATHODE PDF

Seven segment displays are of two types: common anode and common cathode. The Internal structure of both types is nearly the same. A seven-segment display is commonly used in electronic display device for Common Cathode: All the positive terminals (Cathode) of all the 8. In electronics there are two important types of 7-segment LED digital display. Electrical connection of the individual diodes for a common cathode display and.

We also have an option to show a decimal point using the DP pin. Selecting your 7-Segment Display As discussed in the Features there are many options to choose for a 7-segment display.

There many different types of size and colours to select from. If you are planning to make your project look out of the box, then other colour display can also be used.

Also note that as size and colour differs the amount of current consumed by the display will also differ. LED or light emitting diode 7 segment display common cathode P-N junction diode which emits the energy in the form of light, differ from normal P-N junction diode which emits in the form of heat.

Whereas LCD use properties of liquid crystal for displaying and do not emit the light directly. All the positive terminals are left alone.

7 Segment Display

The difference between the two displays is the common cathode has all the cathodes of the 7-segments connected directly together and the common anode has all the anodes of the 7-segments connected together. Shown below is a common anode seven segment.

Common Cathode The common anode display is the exact opposite. To turn on an individual segment, you ground one of the pins.
