I know pretty much *nothing* about OLEDs.
Regular LEDs are made from various inorganic materials, using elements & compounds such as gallium, arsenic, nitrogen, indium, aluminum, phosphorus, silicon carbide, di-aluminum trioxide, and others.
Organic LEDs, when severely abused, have been known to strike back at their tormentors by mutating into large monsters, which destroy houses, laboratories, trailers, and automobiles like Godzilla or Myotismon in the Japanese shows.
Smaller versions of OLEDs, when abused, inflict porportionately lesser damage; usually limited to stuffing tampons down a wall urinator, flushing Christmas bulbs down a toliet, or exploding violently in the experimentor's face, spraying various smelly & stinky organic acids into the air. :-O
As far as I know, OLEDs are only bright enough to use as individual pixels in a larger display - forget about using them as a light source for a flashlight.
