OLED (Organic Light Emitting Diode) is,
kind of emitting element based on organic compound, a next-generation display device made of liquid crystal that can emit light by itself.
Electrons and holes injected from both sides react upon contact with the emitting layer. The OLED display is created as the reaction generates light and heat.
The OLED display has merits such as high brightness, efficiency, wide view angle, and superior color representation. It also features high operating speed at low voltage.
Diverse display devices can be made as it emits light without any back light.
