[[Image:oled structure.png|thumb|center| 300 px|[http://electronics.howstuffworks.com/oled1.htm OLED structure]]]&lt;br /&gt;
An OLED consists of the following parts:&lt;br /&gt;
*Substrate (clear plastic, glass, foil) - The substrate supports the OLED.&lt;br /&gt;
* Anode (transparent) - The anode removes electrons (adds electron &amp;quot;holes&amp;quot;) when a current flows through the device.&lt;br /&gt;
* Organic layers - These layers are made of organic molecules or polymers.&lt;br /&gt;
**Conducting layer - This layer is made of organic plastic molecules that transport &amp;quot;holes&amp;quot; from the anode. One conducting polymer used in OLEDs is polyaniline.&lt;br /&gt;
**Emissive layer - This layer is made of organic plastic molecules (different ones from the conducting layer) that transport electrons from the cathode; this is where light is made. One polymer used in the emissive layer is polyfluorene.&lt;br /&gt;
* Cathode (may or may not be transparent depending on the type of OLED) - The cathode injects electrons when a current flows through the device.[http://electronics.howstuffworks.com/oled1.htm source]&lt;br /&gt;

==OLED Types==&lt;br /&gt;
There are several types of OLEDs &lt;br /&gt;
* Passive-matrix OLED &lt;br /&gt;
* Active-matrix OLED &lt;br /&gt;
* Transparent OLED &lt;br /&gt;
* Top-emitting OLED &lt;br /&gt;
* Bottom-emitting OLED&lt;br /&gt;
* Foldable OLED &lt;br /&gt;
* White OLED &lt;br /&gt;
