An LCD TV differs from its flat-screen counterpart, the plasma set, in numerous ways. LCD TVs do not burn phosphors, unlike plasma sets, and as a result, they require less power and generate less heat. LCD TVs also offer a brighter picture than plasma sets. Additionally, the display life of an LCD set is longer than that of a plasma TV. LCDs have a display life of around 60,000 hours. A new light source then becomes necessary. A plasma set, on the other hand, has display life of approximately 30,000 hours.
Compared with plasma sets, though, LCD TVs offer less variety in terms of screen size. The biggest screen for an LCD set is 37 inches. Also, the contrast ratio and tracking capabilities of an LCD set are less powerful than those in a plasma TV. Screen burn of images is not a problem with LCD TVs, but pixels can burn out. This results in tiny black and white dots, which can be seen on the screen. These pixels can‚Äôt be repaired, and if the dots become troublesome, the screen itself will have to be discarded.
Pros and cons aside, without a doubt, LCD TVs are revolutionizing the way we watch television at home. LCD sets can be integrated into a viewer‚Äôs living space with unprecedented ease. Using a flat wall mount with the set saves space in a room, while adding about two inches to the screen‚Äôs depth. Tilted wall mounts allow viewers to suspend their sets just above eye level, usually above a mantel or in a bedroom. Tilted wall mounts add about 4-6 inches to a set‚Äôs display depth. Table stands are another option for LCD TV display. These stands are usually custom-designed to suit individual sets. Articulating wall mounts utilize swivel arms for set display. With these mounts, sets can be adjusted in a variety of positions ‚Äì pushed flat against a wall when turned off, or pulled out and turned to either side for convenient viewing from anywhere in a room.
LCDs also work with ceiling mounts. If no wall space is available for the screen, the set can easily be suspended from the ceiling and tilted downward. Ceiling mounts utilize poles, which range in length from 24 to 43 inches.
