OLED http://www.oled-info.com stands for Organic Light-Emitting Diode"—an LED composed of thin films of organic compounds. OLED's can be used in TV screens, computer screens, cell phone screens and other displays, with both advantages and drawbacks compared to more traditional technology.
Benefits and Drawbacks
OLED displays have inherent differences with other display technologies, including inorganic LEDs and LCDs. They emit less light than LEDs, but also use less power. Unlike LCDs, they do not require backlighting, a feature that both saves energy, potentially improves picture quality and allows for thinner screens. However, OLEDs can decay, becoming less luminous over time, particularly with sustained use.
