/* OLED Construction */
An OLED can be made of a single layer of organic material but multiple layers increase efficiency and effectiveness. A typical OLED is comprised of five layers of material as follows:
[[Image:* '''Anode layer''' – the anode layer is transparent and is positively charged. When an electric current is applied this layer attracts electrons as they flow through the OLED. As with a LED, the anode forms “holes” into which electrons fall. :* '''Cathode layer''' – this layer injects electrons into the OLED when an electric current is applied. Depending on the OLED and the color effect desired, this layer may or may not be transparent. :* '''Emissive layer''' – this layer transports electrons from the cathode. It is also made of organic plastic molecules but these are different from those in the conducting layer. This is the layer that determines the color of the light emitted. :* '''Conducting layer''' – this layer is made of organic plastic material and transports the “holes” from the anode layerprocess-led.jpg|thumb|center|600px]]
