A liquidcrystal display (LCD) is a flat panel display, electronic visual display, or video display that uses the light modulating properties of liquid crystals (LCs). LCs do not emit light directly.
LCD displaysare available to display arbitrary images (as in a general-purpose computer display) or fixed images which can be displayed or hidden, such as preset words, digits, 7-segment displays, etc., as in adigital clock. They use the same basic technology, except that arbitrary images are made up of a large number of small pixels, while other displays have larger elements.
LCDs are used in a wide rangeof applications, including computer monitors, television, instrument panels, aircraft cockpit displays, signage, etc. They are common in consumer devices such as video players, gaming devices,clocks, watches, calculators, and telephones. LCDs have replaced cathode ray tube (CRT) displays in most applications. They are available in a wider range of screen sizes than CRT and plasma displays, andsince they do not use phosphors, they cannot suffer image burn-in. LCDs are, however, susceptible to image persistence.[1]
The LCD is more energy efficient and offers safer disposal than a CRT. Itslow electrical power consumption enables it to be used in battery-powered electronic equipment. It is an electronically modulated optical device made up of any number of segments filled with liquidcrystals and arrayed in front of a light source (backlight) or reflector to produce images in color or monochrome. Liquid crystals were first developed in 1888.[2] By 2008 worldwide sales of televisions...
