small molecule OLED (SMOLED)

Two different material technologies are being pursued in the development of Organic Light Emitting Diodes(OLED):

One works with very small molecules and is called Small Molecules OLED (SMOLED), the other uses polymers. The advantage of the former technology is its higher efficiency and luminous efficacy, while that of polymers is that they are easier and cheaper to manufacture. For example, polymer OLEDs in printed electronics can be printed on film using printing presses, whereas SMOLED technology requires a vacuum in which the small molecules are vapor deposited.
