LCD hire
Short for liquid crystal display, a type of display used in digital
watches and many portable computers. LCD displays utilize two sheets
of polarizing material with a liquid crystal solution between them.
An electric current passed through the liquid causes the crystals to
align so that light cannot pass through them.
Each crystal, therefore,
is like a shutter, either allowing light to pass through or blocking
the light.
Monochrome LCD images usually appear as blue or dark gray images on
top of a grayish-white background. Color LCD displays use two basic
techniques for producing color: Passive matrix is the less expensive
of the two technologies. The other technology, called thin film transistor
(TFT) or active-matrix, produces color images that are as sharp as
traditional CRT displays, but the technology is expensive. Recent passive-matrix
displays using new CSTN and DSTN technologies produce sharp colors
rivaling active-matrix displays.
Most LCD screens
used in notebook computers are backlit to make them easier to read..
