OLED (organic light-emitting diode) is a with a film of organic semiconductor compound which emits light when being connected to an electric current. OLEDs are so far mainly used to create digital displays in television screens, computer monitors, mobile phones etc., but currently major research is being done for the development of white OLED for the use in SSL (solid state lighting).
   
 
OLEDs are thin, light and flexible instead of rigid. Another advantage of OLEDs is their broad beam angle and a relatively easy production process. So far the key obstacles for a further market penetration of OLED in the area of SSL has been its fragility, reduced life span and particularly its low luminosity and high cost.
Osram has lately released new data, predicting a luminosity increase of 125 lumen per Watt for OLED by the year 2018 connected with significant price drops. Osram has furthermore stated that it will increase investment into further OLED research & development in order to incorporate OLED for general lighting purposes and tail lights in the for the car industry.
According to Osram, the current OLED luminosity values of only 40lm/W will be increased 70lm/W, by 110lm/W in 2016 and 125lm/W in 2018. If these predictions prove to become true, OLED will  compete with LED in the area of solid state lighting within few years. Various top LED manufacturers have increased their investment into research and development of OLED as well and it only seems to be a question of time that OLED will be applied widely within solid state lighting.gm.
