Buying
a High Definition Television (HDTV)
Widescreen
HDTV's: High Quality & Less Space
HDTV, also known as high definition television
is becoming more popular because it offers viewers a clearer
picture, better sound, progressive scanning and a wider viewing
screen. Widescreen televisions sets are a top choice for consumers
looking to set up a home theater system, too. With the FCC
pushing to make a switch to all HDTV, consumers are beginning
to see the wide screen appeal of HDTV.
Digital broadcast is slowly emerging for television. Because
of the 1990 announcement by the FCC that all television sets
be converted to digital by 2006, many broadcasters and television
manufacturers are making the switch. Converting to all digital
was originally prompted by the thought that digital television
will provide a better viewing experience and free up broadcast
spectrums. These spectrums will then be used for emergency
communications for first responders. The government has tried
making the switch to digital easier for broadcasters by giving
them simultaneous channels to broadcast in both high definition
and analog. Many broadcast channels now broadcast both ways.
There
are three types of digital television signals that currently
broadcast. They are SD for standard definition, ED for enhanced
definition and HD for high definitions. The SD and ED signals
can be broadcast with a traditional square screen or in a movie-like
widescreen with reduced picture quality. HD signals however,
are all widescreen, which makes the picture crisper and clearer.
When
shopping for a HDTV, there are many sizes and styles to
choose from. LCD microdisplays are probably the most popular
of the HDTV sets. It is a rear projector that uses three small
LCD panels. Each panel is less than one inch diagonal and has
the capability to produce high definition wide screen images
up to 70 inches. The LCD panels are made up of a grid of transistors
that create a pixel structure. When the transistors are charged,
tiny rotating crystals suspend in a liquid inside the panel.
The crystals are like tiny shutters that control the amount
of light that passes through each panel. The light is reflected
on a mirror and through a projection screen, which creates
the full color high definition picture.
Direct
View CRTs and Microdisplays are two other types of televisions
using high definition technology. A direct view
CRT is a traditional type television with a picture tube that
is updated to display high definition images. They are available
in widescreen. A microdisplay is a rear projection television
with a depth of less than 20 inches. They come in LCD, DLP,
and LCoS.
When choosing a high definition television, consider
the size of TV bases on the resolution. Check to see how far the TV
set will be to where the viewers will sit. There are ideal
distances to see the picture resolution. For example, for optimal
viewing, a high definition widescreen that measures 50 inches
should be viewed at about 117 inches, or just less than ten
feet from the screen.
HDTV widescreen televisions are becoming popular choices for
consumers wanting a movie theater-style viewing experience
at home. Imagine sitting in a home theater with a large, clear
screen and surround sound. With HDTV widescreen TV, it is possible.
There
are several benefits of HDTV widescreen, making it a top
choice for movie lovers. HDTV widescreen sets enable movies
to be seen as the filmmaker intended them. It appears as it
does in the theater and the viewers see every bit of the movie
that is intended. With widescreen, the TV screen cuts off no
part of the image, either at the top or the bottom. Widescreen
shows the colors and lighting correctly. The viewing ratio
is not distorted as it often is in a regular television screen.
The drawbacks of widescreen are few, although there is a couple.
For one, the image on the screen is sometimes smaller. The
film images may show less resolution on a widescreen. The benefits
of a clear, crisp picture, superior audio and wider viewing
area far outweigh the negative.
Consumers will appreciate the high quality of the widescreen.
Also, widescreen televisions often take up less space than
a traditional TV, making it perfect for small theater rooms.
Most DVD movies now that are available for purchase come formatted
in the widescreen version, making it work hand in hand with
the television set.
