Organic Light Emitting Diode. An OLED uses a layer of organic semiconductor material for its emissive electroluminescent layer (the “stuff” in an LED that creates light in response to electric current). OLEDs do not require a backlight and can display better blacks. OLEDs can be made thinner and lighter than LCDs. OLEDs can also provide better contrast in low-light situations than LCDs.
OLEDs are used as displays for various types of digital devices as well as for televisions, computer monitors, cell phones, PDAs, and more.
