connected by a communications link that enables any
device to interact with any other on the network.
LED (Light Emitting Diode)
uses light-emitting diodes (LEDs) as the source of light,
which offers long life and high efficiency output. Multiple
diodes are used together, since the light created by
individual light-emitting diodes is small compared to
incandescent and compact fluorescent lamps.
LCD (Liquid Crystal Display)
liquid substance between two transparent electrode panels.
When an electric current passes through the electrodes, the
molecules in the liquid form a crystalline pattern that
polarizes the light passing through it. A filter over the
electrodes permits only non-polarized light to pass to the
surface of the display, creating light and dark pixels.
