7 SEGMENT

7-Segment Display Features

• Available in two modes Common Cathode (CC) and Common Anode (CA)
• Available in many different sizes like 9.14mm,14.20mm,20.40mm,38.10mm,57.0mm and 100mm (Commonly used/available size is 14.20mm)
• Available colours: White, Blue, Red, Yellow and Green (Res is commonly used)
• Low current operation
• Better, brighter and larger display than conventional LCD displays.
• Current consumption : 30mA / segment
• Peak current : 70mA

Common Cathode (CC) 7 Segment Display
The common cathode display is commonly called CC display. In this type the common pin on the 7-segment display is connected to all the eight Cathode pins of the LEDs. So In order to make this type of seven segment display to work we should connect he Com pin to the Ground pin and power the other pins with Vcc (+5V typically).

Common Anode (CA) 7 Segment Display
The common anode display is commonly called CA display. In this type the common pin on the 7-segment display is connected to all the eight Anode pins of the LEDs. So In order to make this type of seven segment display to work we should connect he Com pin to the Vcc (+5V typically) and ground the required segment pin to turn it on.
