An Organic Light Emitting Diode or OLED can be an electronic device that emits light when a voltage is applied across its terminals. In place of regular LEDs which use inorganic compounds, since organic compounds are used using levels within these devices, it's called an Organic LED. Some are resistive in nature and since some levels are conductive, the unit is called an organic semi-conductor.

They can be used in the production of visual display screens for advertisement display boards, computer monitors and laptops, televisions, and display monitors in information kiosks.

While LCDs (Liquid Crystal Displays) that are generally used nowadays need a to illuminate the display, an OLED does not have any need for it. This substantially reduces the energy element OLEDs which could function for a longer time from the same battery source. Moreover, the lack of the circuitry allows the display unit to become much thinner than conventional displays.

The device generally contains a layer, an, an layer and a cathode. When a is used across the device making the anode positive and the cathode negatively charged, an electrical current starts to flow through the device. As the anode draws electrons in the conductive layer, the cathode emits electrons towards the emissive layer. That is also comparable to the anode supplying electron holes towards the conductive layer. The holes and the electrons are pushed towards one another as a result of the voltage applied across the system, and they mix together at the emissive layer which results in an radiation whose frequency is within the visible range. Ergo light is seen to be released in the OLED. This phenomenon is known as electro-fluorescence. Various organic substances are employed within the levels to build different colors of light.
