Light-Emitting Diode: Organic Light-Emitting Diode
built 636 days ago
OLED = organic light-emitting diode. It's an amazing new technology that will enable extremely thin TV's with a contrast ratio that is about 100 times better than the best consumer LCD's or Plasma's on the market today.

OLED stands for Organic Light Emitting Diode. The "organic" in OLED refers to organic material. Carbon is the basis of all organic matter. Examples of carbon-based substances include sugar, wood and the majority of plastics. The "LED" stands for "Light Emitting Diode" and describes the process of converting electric energy into light. There are two types of OLED — small molecule OLED and polymer OLED.

The company took the wraps off the first Organic Light Emitting Diode television in the United States. About the thickness of three credit cards, the new OLED-TV (model XEL-1) offers picture quality with high contrast of 1,000,000:1, outstanding brightness, exceptional color reproduction, and a rapid response time.

If the emitting layer material of the LED is an organic compound, it is known as an Organic Light Emitting Diode (OLED). To function as a semiconductor, the organic emitting material must have conjugated pi bonds. The emitting material can be a small organic molecule in a crystalline phase, or a polymer. Polymer materials can be flexible; such LEDs are known as PLEDs or FLEDs.

OLED (Organic Light Emitting Diode) is a display technology. Unlike LCD displays which work by reflecting light, either ambient light or in its absence a backlight, OLED displays emit their own light and are legible in dark environments without an extra backlight, which helps reduce power consumption.

The growing number of electronic devices using organic light emitting diode displays shows that after years of promise, the technology is finding a home in more and more products. But while OLED displays might challenge LCDs as the screens of choice for smaller gadgets, the technology is not expected to become mainstream for notebook PCs or TVs within this decade.
