| | How does OLED emit light? |
| | The basic structure of OLED is a sandwich formed with a thin and transparent semiconducting anode of Indium Tin Oxide (ITO) and a metal cathode on both sides of an organic substrate.
The organic material comprises hole transmission layer (HTL), emitting layer (EL) and electronic transmission layer (ETL).
When a proper voltage provided by the battery (low voltage property) is applied, holes injected in the anode and electric charges from the cathode meet and combine at the illuminating layer and excite electroluminescence; structure of the organic layer and design and choice of the anode and cathode are key factors to the light emitting efficiency of the OLED device.
