Polymer LED (light-emitting diode) - sometimes called
light-emitting polymer or polyLED - is a technology based on the use of
polymer as the semiconductor material in LEDs. Dow Chemical Corporation
announced the discovery of light-emitting polymers at the spring meeting
of the Materials Research Society in 1998. Polymers are chemical substances
that consist of large molecules that are, themselves, made from many smaller
and simpler molecules: proteins and DNA are examples of naturally occuring
polymers; many others, such as nylon, are artificially created. Because
of their flexibility and strength, polymers are used for products such
as car bumpers and bullet-proof vests.
