Organic light-emitting diode (OLED) is a light-emitting diode (LED) made of semiconducting organic polymers. The best efficiency of an OLED so far is about 10%. These devices promise to be much cheaper to fabricate than inorganic LEDs, and large arrays of them can be deposited on a screen using simple printing methods to create a graphical colour display.

One of the great benefits of an OLED display over the traditional LCD displays found in computer displays is that OLED displays don't require a backlight to function. This means that they draw far less power and they can be used with portable devices which mostly use monochrome low-resolution displays. This will also mean that they will be able to last for long periods of time with the same amount of battery charge.

The world's first digital camera with OLED display was the Kodak LS633 model revealed at the Photo Marketing Association (PMA) trade show in March 2003.
