Organic light-emitting diode (OLED) is a type of light-emitting diode (LED). The part of the OLED that creates light is made of a very thin layer of organic compounds. The main use of OLED technology is for flat panel displays for smartphones and other mobile devices where they are in some ways better than LCDs. OLEDs can be used to make displays that can bend. These can be used in many different ways. For example, they can be used in clothing.
