Understanding Organic LED

OLED stands for organic light-emitting diode, an advanced version of LED, OLED relies on an organic material made of hydrocarbon chains which emit lights when electricity passes through it. They are used in new applications in the area of lighting and displays. 


How does OLED work?

OLEDs work in a similar like LEDs, but they use organic molecules to produce the electrons and holes instead of a p-n junction. An OLED consist of six different layers. On the top and the bottom, there are same layers of protective plastics or glass. The top layer is termed as the seal and the bottom layer termed ad the substrate. There is a positive and negative terminal in between those layers. Between these positive and negative layers, the organic molecule is produced forming two-layer called the emissive layer and conductive layer. Emissive Layer is the layer where the light is produced.


OLED Uses.

Nowadays OLED is used on displays wherever you can use LCDs, like Television and computer screens, phones display etc. In future, they'll find many other exciting applications due to their properties like greater brightness, better color reproduction and thinness.
