PLED
|
Polymer light emitting diode. The most advanced display technology, based on the use of organic polymers which emit light when stimulated electrically. Also described as polymer light emitting device or polymer light emitting display. PLEDs are a form of OLED (see below). Developed after SMOLEDs, PLEDs have the major advantage of being solution processable, and can therefore be applied to substrates using techniques such as ink jet printing.

Alternative terms for PLED
|
|
| OLED |
Organic light emitting diode. Devices which use organic materials to produce light through electrical stimulation. The term OLED includes PLED, SMOLED and dendrimer technologies. |
|
| SMOLED |
Small molecule organic light emitting diode. The original technology developed to exploit the light emitting property of some organic chemicals. Has been the basis of most commercial products to date, but has the disadvantage of requiring complex and expensive production methods such as vacuum deposition. |
|
| Dendrimer |
A class of molecule featuring a high degree of branching and which can be designed to offer specific performance characteristics. In particular, in display technologies, dendrimers can be used with small molecules to give them some of the properties of polymer systems e.g. solution processability. |
|
|
SMF
Spin coating
Vacuum deposition
|
SMF - Sublimed molecular film. These are all techniques used to deposit light emitting materials in the production of displays. |
|
| OEL |
Organic electroluminescence. The phenomenon of light emission as a result of electrical stimulation of an OLED. |
