What is OLED?
OLED (Organic Light-Emitting Diode) is a self light-emitting technology composed of a thin- multi-layered organic film placed between an anode and cathode. In contrast to LCD technology- OLED does not require a backlight. OLED possesses high application potential for virtually all types of displays and is regarded as the ultimate technology for the next generation of flat-panel displays.

How Does OLED Emit Light?
OLEDs basic structure consists of organic materials positioned between the cathode and the anode- which is composed of electric conductive transparent Indium Tin Oxide (ITO). The organic materials compose a multi-layered thin film- which includes the Hole Transporting Layer (HTL)- Emission Layer (EML) and the Electron Transporting Layer (ETL). By applying the appropriate electric voltage- holes and electrons are injected into the EML from the anode and the cathode- respectively. The holes and electrons combine inside the EML to form excitons- after which electroluminescence occurs. The transfer material- emission layer material and choice of electrode are the key factors that determine the quality of OLED components.
