Liquid crystal display television or LCD TV uses LCD TFT technology, more often than not, for visual output as opposed to the conventional cathode ray (of the original TV) or plasma technology.
LCD television initially faced problems entering the market, particularly when it came to viewing fast paced action. Also, the viewing angle was rather limited. However, with the advancement in technology, these problems have more or less been wiped out. Today LCD television commands a burgeoning market, especially in the Asian region.
For quite a long time, the general consensus was that the technology used for LCD television was appropriate for small televisions only, and would invariably fall short of plasma technology when it came to bigger televisions. However giant corporations like Samsung, Sharp Corporation and LG Philips have challenged this notion by coming up with LCD televisions with distinctly large panels. 40″ to 45″ televisions were widely in the market a year ago. Sharp Corporation has successfully produced a 65″ panel LCD television. In 2004, Samsung and Sony joined hands to build a factory, with the intention of manufacturing 60,000 panels every month. In 2005, Samsung proclaimed the successful completion of an 82″ HDTV TFT panel. It is believed that the LCD market is potentially worth billions of dollars, and television is seen as the main market.
TVs based on S-PVA LCD panels produce good viewing angles. They also give sufficient
“contrast ratio” for viewing scenes that are bright, as well as dark scenes in bright conditions. Also “dynamic contrast” technology improves contrast when one is viewing dark scenes in dark conditions. Also, there are LCD televisions that throw light on the background to help make dark scenes look darker.
Today, LCD televisions are offering greater viewing angles and better quality images. LCD televisions can also be deemed direct competition to the fashionable plasma televisions. However, LCDs are distinctly lighter and comparatively more durable.
LCD technology is “non-emissive”, in that it does not give off radiation like conventional televisions. Furthermore, their operation requires less power than plasma or CRT technology.
