OLED, or Organic Light Emitting Diode, is the latest advancement in the field of LED lighting technology. In normal LEDs, the electroluminescence is provided by a semiconductor strip, whereas in an OLED, the luminescence is provided by a strip of organic material.
There are various advantages of using OLEDs. They have better power efficiency than equivalent LCD screens, since they do not use a backlight. This also enables OLED screens to show true black. The next major advantage is that picture quality is much improved because of higher refresh rates. While LCD screens manage a refresh rate of around 200 Hz, OLED screens can have refresh rates of more than 100000 Hz.
