4 Digit 7 Segment Display Common Anode

This 4 digit 7 segment common anode is a type of electronic display module that uses seven segments to display decimal numerals. The segments are arrange in a rectangular shape, with each digit consisting of a top segment, a middle segment, a bottom segment, and four side segments. The common anode means that all of the anodes of the segments are connect together, and each segment is turn on by applying a low voltage to the corresponding cathode.

4 digit 7 segment common anodes are commonly used in digital clocks, calculators, and other electronic devices. They are also used in some LED displays, as they can be more efficient than common cathode displays.

The input voltage of a 4 digit 7 segment common anode typically ranges from 3.3 to 5 volts. It is important to note that the input voltage must be higher than the forward voltage drop of the LEDs in the display. The forward voltage drop of an LED is typically around 1.8 volts, so the input voltage must be at least 2.8 volts to ensure that the LEDs will turn on.

The working principle of a 4 digit 7 segment common anode is base on the fact that LEDs will light up when a current is passed through them. In a common anode display, all of the anodes of the segments are connect together, and each segment is turn on by applying a low voltage to the corresponding cathode.

The segments of a 4 digit 7 segment common anode are arrange in a rectangular shape, with each digit consisting of a top segment, a middle segment, a bottom segment, and four side segments. The segments are label A through G, and the decimal point is typically label DP.
