8.4.2. Types of 7-Segment Displays

Try these first

1. 1.

   What are the two types of 7-segment displays?

   Hint

   Think about how the segments are connected.

2. 2.

   How does a common cathode display light up a segment?

   Hint

   Focus on the voltage requirement.

3. 3.

   What type of connection do common cathode displays use?

   • All anodes connected
   • All cathodes connected
   • Both anodes and cathodes connected

   Hint

   Remember which part connects together.

4. 4.

   True or False: In a common anode 7-segment display, the segments are lit by applying a positive voltage to the cathodes.

   • True
   • False

   Hint

   Think about the role of grounding in display operation.

5. 5.

   Design a circuit using both common anode and common cathode displays. How will you address the differences in control?

   Hint

   Think about the configuration setup for each type.

6. 6.

   Explain how you would display the number '5' on both types of displays, detailing the binary values needed.

   Hint

   Refer to your digital encoding for numbers on 7-segment.
