LEDs And OLEDs Light Up Markets [General Electric Company, Cree, Inc., Sony Corporation (ADR), SAMSUNG ELECT LTD(F), Koninklijke Philips NV (ADR), Avago Technologies Ltd, LG Display Co Ltd. (ADR)] - Seeking Alpha

Other disadvatages, though, are that organic OLEDs are more susceptible to humidity and temperature along with a shorter lifespan.
