7.11 One-Digit Seven-Segment Display
LED segment displays are common for displaying numerical information. They are widely applied on displays of
ovens, washing machines, etc. the LED segment display is a semiconductor light-emitting device. Its basic unit
is an LED (light-emitting diode). Segment displays can be divided into 7-segment and 8-segment displays.
According to the wiring method, LED segment displays can be divided into displays with common anode and
displays with common cathode. Common anode displays refer to displays that combine all the anodes of the
LED units into one common anode (COM).
