LEP, LED, LCD...eh??

There are a fair few acronyms, here I decode them for you.

LEP

Light Emitting Polymer. A polymer that fluoresces when a potential difference is applied.

LED

Light Emitting Diode. The hard-disc light on your computer is almost definately an LED. Cheap, long-life, low power, LEDs are small, bright light sources that come in a range of colours. The technology is similar to that in PLEDs..

PLED

Polymer Light Emitting Diode. An LEP sandwiched within a diode. A PLED cross-section is shown below.

OLED

Organic Light Emitting Diode. A form of LED that uses organic substrates as oppossed to usual silicon mix.

LCD

Liquid Crystal Display. Not related to LEPs. A form of display technology currently in use.

CRT

Cathode-Ray Tube. Your TV. Your computer monitor. They use CRTs to create an image.

If you came from the introduction, you should now proceed to the Applications of LEPs
