Difference Between LED and OLED?

Biggie's thread here: https://www.crazyengineers.com/community/threads/oled-tvs-may-cost-8000.53175/ got me thinking.

From what I know LEDs are very similar to LCDs. How exactly do the organic LEDs differ from LEDs? And what makes them better?

Could anyone explain?

Well main difference between LED and OLED is in its construction Typical LED has semiconductor material and it emitts light when Electron gets charged from supply and it come backs to its normal orbit and Light emission takes place while as per my basic knowledge about OLED I come to know that Oraganic material used in OLED is also having Light emission charactristics and it is due to the thermal conductivity of that material.

They can be made using a flexible film. They are much lighter and the current technology allows HD displays. Other than that they are LEDs in function.
There is plenty of info available on the net.

Alright.
If I understand it right, it can be done two ways. One is thin and the other is capable of really good contrast.
The thin ones are edge lit and are subject to the raw contrast limitations of the LCD.

Does this mean (from what I've heard) they don't have the limited lifespan of OLED? (It was something as low as 4 years.)
