Liquid Crystal Display (LCD) Technology - LCD
is the technology used for displays such as notebooks, small computers,
pagers, phones, and other instruments. The display uses a combination
of fluorescent-based backlight, color filters, transistors, and liquid
crystal to create and illuminate images. Like LED and gas plasma technologies,
LCDs enable displays to have a smaller form factor than the traditional
CRT (cathode ray tube). Moreover, they also consume much less power than
LED and gas plasma because they block light rather than emit it. An LCD
has either a passive or active matrix display grid. The widely used active
matrix, also known as thin film transistor (TFT) design, places vertical
and horizontal TFT lines on one plane to form a true matrix, requiring
less current.
