WebLight Emitting Diode (LED) Definition: The LED is a PN-junction diode which emits light when an electric current passes through it in the forward direction. In the LED, the recombination of charge carrier takes place. The electron from the N-side and the hole from the P-side are combined and gives the energy in the form of heat and light. Web7 Segment Display Current Limiting Resistor. A current limiting resistor is required for each segment of a 7-segment display. Each resistor provides a voltage drop for each diode in the segment. An advantage of this circuit is that all the LEDs will light with equal intensity, because each has the same amount of current passing through it.
