Home Theater Systems

Have you ever been to homes where the people have their very own home theater projectors? Why not you? Depending on your home theater design, LCD Projectors are a typically less expensive method of getting a fantastic home cinema experience! LCD is an abbreviation of 'liquid crystal diode'. These projectors contain three separate LCD glass panels, one each for red, green, and blue components of the image signal being transferred to the projector.

As the light passes through the LCD panels, individual pixels can be electronically opened to allow light to pass or closed to block the light. This activity modulates the light and produces the image that is projected onto the screen. Since the primary colors: Red Green, and Blue make up the entire color spectrum that is visible to us, effectively modulated this technology can display a very accurate image.

Just a few years ago, having a flat screen television to home theater systems meant spending a large sum of money on a technology that was still in its early stages of development.

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!
