OLEDs are comprised of electrically active organic material placed between an anode (an electron-expelling electrode) and a cathode (an electron-receiving electrode). Carbon is the basis of the OLED’s organic matter. The "LED" stands for "Light Emitting Diode“, and describes the process of converting electric energy into light. When an electric current runs through the system, the anode sends electrons to the cathode, creating a current through the organic material. This charges the organic material, and when positive and negative charges hit the same molecule, it releases a photon, which we perceive as glowing effect.
