It stands for light emitting diode. A digital clock that can be seen in the dark is an example. LED's are diodes that light up when current passes through them. Light them in certain sequences and you can use them to display stuff.

LED stands for Light Emitting Diode. Some digital clocks and other electronic devices that have displays use them. Now there are flashlights that use them and they are really bright.

Alarm clocks with constantly on red displays are LED displays. Many message boards that you see in stores or offices are also LED-based, as are traffic signals in many cities.
