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, or transmissive,
to make them easier to read.
