 • Anode: The anode removes electrons as current flows through the device.

 • Organic layer: The organic layer is composed of organic molecules or organic polymers.

* Conductive layer: This layer consists of organic plastic molecules that transport "holes" from the anode. Polyaniline can be used as the conductive polymer of OLED. * Emissive layer: This layer consists of organic plastic molecules that transport electrons from the cathode; the luminescence process takes place at this layer.

 • Cathode: When there is current flowing in the device, the cathode will inject electrons into the circuit.

 The principle of 0LED illumination is as follows:

 The battery or power supply of the 0LED device applies a voltage across the 0LED. Current flows from the cathode to the anode and through the organic layer. The cathode outputs electrons to the organic molecular emission layer. The anode absorbs electrons from the organic molecular conduction layer. At the junction of the emissive layer and the conductive layer, electrons will combine with the holes. When an electron encounters a hole, it fills the hole. When this process occurs, electrons release energy in the form of photons. At this point, the 0LED device starts to emit light. The color of the light depends on the type of organic molecules in the emissive layer. The manufacturer will place several organic films on the same 0LED to form a color display.
