What Is Rear Projection Television?




By Scott Michaels

What is rear projection television? The term comes from the
fact that the rear projection TV sends the image onto the
viewing screen from behind the screen. When you are in a
movie theater, the image in projected onto the front of the
screen. That is why the projector is behind the audience in
a movie theater.

If you are really into television, that the bigger the screen
the better, right? If you feel that way about your television
viewing, then no doubt you are considering moving up to the
big,big televisions that are now available in the market.

While most of the recent interest is on flat screens and LCD
screens, improvements in rear projection TV makes this a wise
purchase to consider. Advances in the quality of the picture
using rear projection TV make this a reasonable and less
expensive alternative to the big flat screen televisions.

Advances in the technology of rear projection TV provide a
variety of models that have never been available before. Your
normal television set probably uses a CRT or cathode ray tube
to project the image. Many rear projection TV use the same
technology.

These units are quite large though when you increase the screen
size very much. There are offsetting picture quality benefits.
You may get better blacks and colors, but if the image is not
properly aligned, this type and rear projection TV can produce
improper color blending.

Another type of rear projection TV is based on a Liquid Crystal
Display. However, this is not the same as the LCD used in a
flat panel screen. This type of rear projection TV offers many
advantages including that the size of the unit is quite small
in comparison to the CRT models.

There is high contrast and brightness in the LCD based rear
projection TV picture. Some disadvantages also exist. I will
not go into the 'technical' but sometimes the image looks a
little fuzzy, described as trying to watch TV while looking
through a screen door.

Perhaps the newest rear projection TV technology is called
Digital Light Processing. As the name implies, your television
image is digitized and computerized and whatever else high
technology does, but you get a great picture quality without
some of the disadvantages of the other types. Problems with
this type of rear projection TV is that include what is called
the 'rainbow' effect if you move you eyes quickly from the TV
to the surrounding room.

Find a reputable dealer, explain your viewing needs, and look
at the different types of rear projection TV yourself. There
is no reason not to have the best and biggest viewing
experience with all this new technology in the rear projection TV.
