Now, prices are a fraction of what they were, and the technology has seen vast improvements over the years. So what is LCD TV? How does it work?
An LCD TV is a flat panel television containing LCD panels made of two layers of transparent material, which are polarized, and "glued" together. One of the layers is coated with a special adhesive polymer that holds the individual liquid crystals. Current is then passed through individual crystals, which allow the crystals to pass or block light to create images. LCD crystals do not produce their own light, so an external light source, such as LEDs (light emitting diode) or florescent bulb is needed for the image created by the LCD to become visible to the viewer.
Unlike standard CRT and Plasma TV, since there are no phosphors that light up, less power is need for operation and the light source in an LCD TV generates less heat than a Plasma or traditional television. Also, because of the nature of LCD technology, there is no radiation emitted from the screen itself.
In today's consumer electronics market, sizes range from 19 to 70 inches.
If you enjoy video games along with your movie watching and television viewing, then an LCD TV might be just the ticket!
Depending on your home theater design, another option to consider is a home theater projector if you need an even bigger screen presence.
No matter what technology you decided to go with, so many great options for your home theater system are available for you to choose from!
