An LCD TV is a flat panel television that utilizes the same time-proven Liquid Crystal Display technology found in cell phones, camcorder viewfinders, and computer monitors.
Pros and Cons
LCD televisions are thin, lightweight and easy to move, and some are wall-mountable, providing drastically greater options for home theatre setup. LCD TVs offer a steadier, flicker-free picture, virtually eliminating the burn-in of static images. LCD televisions also boast a longer display life (about 60,000 hours, at which time all you may need to do is replace the light source, not the entire set). This can vary according other environmental and use factors.
LCD TVs used to be hampered by a lower contrast ratio, offering less ability to render deep blacks, and were not available in screen sizes above 40 inches. This is no longer the case. Seventh-generation systems by Samsung, Sony, LG, Philips and Sharp offer contrast and brightness to rival plasma screens, and Sharp has displayed an LCD screen of up to 108"
