What Is LCD Technology?
Like popular LCD monitors you commonly see used with computers, LCD TVs have a slim design and a flat viewing surface, but have been fine tuned for video display. Recent advances in flat panel LCD technology now allow for larger screens, wider viewing angles, and higher-quality video images. LCD TVs are also competition for trendy-but-heavy, plasma display technology. They are several times lighter than comparably sized plasmas, and are far more durable.
How do LCD TV's work?
Two sheets of polarized transparent material, one with a special polymer coating that holds liquid crystals, are adhered together. Electric current is passed through individual crystals, which interpret the information from the broadcast signal to allow or disallow light through them to create an image. The crystals themselves do not produce light, so the technology is "non-emissive" and therefore does not give off radiation like an older television does. Fluorescent tubes housed behind the transparent material illuminate the image. They require less power to operate than CRT and plasma televisions which require powering hundreds of electrodes to stimulate the phosphorous.
LCD TVs At-A-Glance:
Use non-emissive technology; do not emit radiation.
