COB COG 7 Segment Size Monochrome LCD Display Screen Module
7 segment display is an old school Opto-Electronic Display device mainly used to display alphabets and digits. As the name suggests, these displays include seven segments that switch ON & OFF to display the required digit or alphabet. The segments in this display are normally single LEDs or liquid crystals. These displays are extensively used in electronic meters, digital clocks, displays in home appliances, basic calculators, cars & different electronic devices that display numerical data. So let us discuss more about a 7-segment display in this article.
In this type, all LEDs share a common anode terminal while each cathode terminal is connected to a different segment. In order for a segment to light up, the corresponding cathode terminal will be grounded and the common anode terminal is provided with +5V source voltage. To interface a common anode type to a microcontroller then the Cathodes of each segment are connected through appropriate port pins of the microcontroller.
