Organic LED
OLED ..whereabouts..
Definition: Organic light emitting diodes are optoelectronic devices in which the emissive electroluminescent layer is a film of organic compounds which emits light in response to an electric current.
First comprehensive research on polymer electroluminescence culminated in 1990 with J. H. Burroughes e. at the Cavendish Laboratory in Cambridge
