OE

Organic Electronic

Organic electronics is a field of material science concerning the design, synthesis, characterization, and application of organic small molecules or polymers that show desirable electronic properties such as conductivity. Unlike conventional inorganic conductors and semiconductors, organic electronic materials are constructed from organic (carbon-based) small molecules or polymers using synthetic strategies developed in the context of organic and polymer chemistry. One of the benefits of organic electronics is their low cost compared to traditional inorganic electronics. 

OEL

Organic Electroluminescent

This is a generic term for organic light emitting devices typically fabricated from sublimed molecular films. This term is often used in Japan to describe variants of technology that originated with Kodak. 

Ohmic

The electrical contact between two different materials is considered Ohmic if it follows a linear current voltage characteristic (I = U/R).

OLED

Organic Light Emitting Diode

An OLED is a solid-state semiconductor device made from a thin film of organic (carbon-based) materials that emits light when electricity is applied. The use of OLEDs allows for the creation of light-emitting products, such as flat panel displays and luminaires, that are thinner, lighter and more flexible than those produced with LEDs because OLEDs can be applied to a wide variety of substrates, such as glass, metal foil, plastic and potentially textiles. They operate at lower voltages and do not require secondary optical fixtures for controlling light emission.

OLED-A

OLED-Association

OLED-A provides a forum for the interchange of technical and market information. Our membership includes companies involved in small-molecule OLED technology and polymer technology (PLED or light-emitting polymers). OLED-A serves its membership by fostering the more rapid development of OLED technology and OLED products; serving as a resource on OLED markets and products for media and investors; functioning as a catalyst in the development of standards for OLEDs; and providing a forum to promote and market OLED technology products.

OPV

Organic Photovoltaic / Organic Solar Cell

Organic photovoltaics use organic materials to generate electricity from light. Because of their flexibility, light weight, and high performance in low or variable light situations, organic photovoltaics may be used as sources of electricity for portable electronic devices, or in a variety of markets such as building integrated systems, signage, packaging and smart fabrics. The primary photovoltaic device mechanism that has been utilized is that of photoinduced charge transfer between an electron donor and acceptor. Typical solar cells use organic polymers or small molecules for light absorbtion and charge transport to produce electricity from sunlight by photovoltaic effect. 

Organic TFT

Organic Thin Film Transistor

Organic TFT is a display backplane (driver) made from organic materials, which allows for transparency and flexibility. An OTFT may be produced using printing techniques. 

Outcoupling

The escape of generated photons from an OLED panel.

In an OLED, a large part of the photons are trapped inside the OLED—mostly reflected at the substrate/air interface. In an OLED without any outcoupling enhancement typically only 25%–35% of the photons actually leave the OLED panel.
