PLED is short for polymer, or polymeric, light-emitting diode, a backlighting, illumination and display technology.
Polymers are substances formed by a chemical reaction in which two or more molecules combine to form larger molecules. PLEDs are thin film displays that are created by sandwiching an undoped conjugated polymer between two proper electrodes at a short distance. The polymer emits light when exposed to electricity. PLEDs enable full-spectrum color displays and are relatively inexpensive compared to other display technologies such as LCD or OLED and require little power to emit a substantial amount of light.

PLED displays are great for hand held instruments that will not be running all the time. Before designing in a PLED or OLED be aware the life span is from 8000 hr. to 2000 hrs. They are great for medical test instruments where the product is used and then turned off. They have a 160 degree viewing angle, 1000 times faster update speed that an LCD, in fact our 128 x 128 Full Color is capable of full motion video @ 40 frames per second. They achieve a brightness of 80 cd/m². They come in full color 65K and 256K. Most of the OLED Graphics are area color.
