The OLED Technology

The Organic Light-Emitting Diode (OLED) is a luminous display technology, whose first patent was granted in 1987 (to Kodak) and the first commercial application appeared around 1997.

This technology aims at gradually replacing Liquid Crystal Displays (LCD). In particular, OLED will initially replace LCD screens in small size applications (e.g., mobile telephones). Eventually, OLED is expected to replace LCD and other technologies (e.g., plasma) for screens of large sizes.

OLED technology has many advantages compared to LCD:

- Low electric consumption
- Better color rendering (100% of NTSC's diagram)
- Better contrast
- Wider angle of vision
- Thinness and flexibility of the display (it is unclear whether Polymer Vision's rollable screens use OLED or not)

The only weakness is the lifespan, which is not optimal yet (e.g. arount 10.000 hours).
