NettetIV graph of LED is a representation of the relationship between the current flowing through the LED as a function of the voltage across it. Points to be observed from the IV graph … NettetLight Emitting Diodes (LEDs): A Look Inside LEDs have been around for about 30 years. They have found application everywhere, from glowing keychains to TV sets. Generally, an inorganic LED is a device comprised of a semiconductor with two differently doped regions: n-type (electron conducting) and p-type (hole conducting).

What is LED?? • A light emitting diode (LED) is essentially a PN junction opto-semiconductor that emits a monochromatic (single color) light when operated in a forward biased direction. NettetThe “ Light Emitting Diode ” or LED as it is more commonly called, is basically just a specialised type of diode as they have very similar electrical characteristics to a PN junction diode. This means that an LED will pass current in its forward direction but block the flow of current in the reverse direction.
