Welcome to About-OLED.com

OLED is short for organic light-emitting diode. It is a special type of a light-emitting diode, often referred to as the abbreviation LED. OLED is a display device whose emissive layer consists of a thin-film of somewhat organic compounds.

The thin-film is carbon-based and held between two charged electrodes. The first one is a transparent anode which is usually glass and the second one is a metallic cathode. The film comprises of a hole-transport layer, a hole-injection layer, an electron-transport layer and an emissive layer. Luminescent light is created by the injection of positive and negative charges in the emissive layer.

OLED displays require no backlighting, unlike traditional LCDs. This means that they draw less power. This is a huge benefit, especially when the display is operated by battery charge.

The organic light emitting diode technology was first invented in the early 1980s by Eastman Kodak.

OLED displays use less power, are brighter and thinner and have often a higher contrast than traditional LCDs. As a benefit for the manufacture, they are cheaper to produce.

OLED technology is more often used in mobile phones, PDAs, mp3 players, digital cameras and so one. It can also be used as a solid state light resource, e.g. to replace a traditional bulb.

This website is about OLED and its technology. We offer background information as well as news. We have an article section about how OLEDs work and a product page where the technology is already used in the latest devices. You can find also everything about the advantages and drawbacks of this new technology for displays. There is also a section about the comparison of different display technology like OLED, PHOLED, FED, LCD and LED. Plus there is many more information to discover on this website. Feel free to browse around.
