Polymer LED (PLED)
Definition - What does Polymer LED (PLED) mean?
Polymer LEDs are produced by sandwiching electroluminescent polymers between a metal cathode and a transparent anode.
A polymer LED is also known as a PolyLED or a Light-Emitting Polymer (LEP).

Despite the distinct advantages of polymer LEDs, this is still a new technology that has many problems to work out, such as durability. For example, there is still color shift, particularly for blue, which degrades faster. The pixels themselves also have to be encapsulated from air to prevent degradation by oxygen, which takes away from their flexibility quite a bit.
