Organic Light Emitting Diode: Energy efficient material for sustainable green environment (original) (raw)
2017, Proceedings of National Conference RACSGSE-SBAP
An organic light-emitting diode (OLED) is a light emitting diode (LED) constructed by using organic molecules that emits light in response to an electric current. The OLED are highly energy efficient material compared to conventional artificial light sources. The Organic light emitting diode emits light by emissive electroluminescent layer, a film of organic compound. The layer of organic semiconductor is situated between two electrodes in which at least one of the electrode is transparent. Major usage of OLED is in digital displays devices such as television screens, computer monitors, portable systems such as mobile phones, handheld game consoles and other displays. OLED have two main families: those based on small molecules and second class employ polymers as construction unit. The fundamental of OLED construction materials, energy efficiency of new OLED materials and application design has been discussed here.
