Liquid crystal displays (LCDs) and Light Emitting Diodes (LEDs) have become household words because of television screens. Both these technologies are now decades old. Scientists have been working on what are known as Organic Light Emitting Diodes (OLED), made from carbon containing materials. They perform the same tasks more efficiently, and are more flexible.
These devices have the potential to revolutionise all future display technologies, whether for your TV screens or the one on your mobile. Simply put, in OLEDs, the emissive electroluminescent layer is a film of organic compounds that emits light in response to an electric current.
OLEDs allow manufacturers to make displays that use less power, and are so thin that they easily wrap around other structures. They have perfect black levels and bright whites , for an infinite contrast ratio. Bright low power light sources can even be used in making organic lasers. In couple of years, you would be asking for OLED TVs instead of LED ones.😎
