How does lcd tv work ...
Simply put – an LCD TV is a flat panel TV that incorporates the same liquid crystal technology as your camcorder, digital camera viewing screen, cell phone screen and, of course, computer monitors. Like the newer computer monitors, LCD displays have a slim design and a flat viewing screen. The LCD TV has been, specifically, designed to view video images. Because advances in technology have been so rapid the display size of LCD TVs have increased substantially. They come in display sizes from 13 to over 100. LCD TVs are much, much lighter than a comparable Plasma TV and are much more durable as well. However they are also much more expensive than a comparable plasma model.
LCD TVs mostly consist of the flat panel display. The panels are constructed of two layers of polarized, glass like material that is glued together. One of the panel layers is coated with a special polymer material that holds the thousands of individual liquid crystals. Electricity is passed through the individual crystals, which interpret the information from the broadcast signal and allow the crystals to pass or block light – thereby creating images.
Since LCD crystals do not produce their own light they require an external light source that is housed behind the transparent, liquid crystal, panel. This light source causes the liquid crystal to become visible to the viewer. Because LCD technology does not require extra electrodes to stimulate phosphores, as in plasma TVs, the panels are thinner and require less power to operate than plasma TVs. Also, LCD technology is non-emissive - meaning it does not give off radiation.
If one takes all these features, described above, and ad AV input/output connectivity, speakers, a TV tuner, and standard television controls, it is easy to see why the LCD is becoming a very popular choice for home theatre and TV viewing.
