Organic Light Emitting Diodes (OLEDs)

Light from Carbon

An OLED is an electrical device that efficiently converts electricity into light using environmentally-friendly carbon-based organic dye molecules.

History

Although OLEDs are often viewed as being a modern technology, their development is based on pioneering work dating back to the 1950’s and 60's. Learn More...

Working Principle

The working principle of an OLED is very similar to that of a traditional LED, except that organic dye molecules take the place of inorganic semiconductors, such as GaN.

Organic Dyes

Copper phthalocyanine (CuPc) a commonly used organic dye found in blue jeans was also used as one of organic layers in first generation OLED displays.

Electrodes

Getting electrical current to flow through a layer of organic dye molecules isn't easy. The electrode contacts are therefore one of the most important parts of an OLED.

Applications

OLEDs displays can be found in a variety of different portable electronic devices, such as smart phones, in ultra-slim and light flat-panel televisions, as well as in next generation light sources.

Other Devices

OLEDs are only one example of the many useful electronic devices that can be made with organic molecules. Other examples of so called "Organic Electronics" include organic solar cells, photo-detectors, and thin film transistors.
