A New Breed of Televisions for HDTV
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. Wide-screen televisions sets are a top choice for consumers looking to set up a home theater system, too.
When shopping for a new HDTV set, the choices and options can be perplexing. There are many different types of HDTV sets available. There is definitely a new breed of televisions for HDTV.
Most HDTV sets that are available for sale are big screen and they are generally expensive. Smaller-screened televisions with digital capabilities are slated to hit the market in 2007. It is estimated that only about 30 million televisions in the United States have digital tuners, out of the several hundred million sets already installed in homes.
Choosing a high definition television can be confusing. When shopping for a new HDTV, do research and understand the product. It is recommend that you shop around and ask lots of questions before purchasing. HDTV set ups can be costly. Larger sets can run in the thousands of dollars just for the television. Most HDTV sets that are available for sale are big screen and they are generally expensive. Smaller-screened televisions with digital capabilities are slated to hit the market in 2007.
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 wide-screen with reduced picture quality. HD signals however, are all wide-screen, which makes the picture crisper and clearer.
When looking at HDTV sets, 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 n 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.
The choices for HDTV are staggering. Consumers can purchase plasma, LCD (liquid crystal display), DLP (digital light processing) or LCOS (liquid crystal on silicon), which are all types of monitors. There are also projection displays to consider. They also come in LCD, DLP, and LCOS. Many viewers prefer the wall display monitor that either plasma or LCD offers. But, these are usually most expensive of the high definition sets, especially the ones that are sized between 40 to 70 inches. Lower on the cost spectrum, but equally good, are the LCD displays that are sized at 42 inches and under.
There are great benefits of using high definition television. HDTV has over twice the sharpness and clarity of analog TV broadcasts. The color resolution for HDTV sets is far superior. For consumers who have already made the switch to HDTV, they feel this is the biggest advantage of high definition.
The lack of imperfections in the television screen often seen on traditional television is another reason why many prefer high definition to analog. With HDTV, problems such as snow caused from a weak signal, double images from ghosting or multi-path and picture sparkles from impulse noise are a thing of the past. These problems often seen on a conventional television broadcast just do not occur on HDTV.
Screen resolution from a high definition TV broadcast is almost five times as sharp as conventional broadcasts. High definition has double the lines of resolution compared to a traditional analog TV set. While a traditional analog set can only display 525 lines of resolution, HDTV technology takes this one step farther. HDTV broadcasts can display 1080 horizontal lines of resolution. This makes a huge difference in the picture clarity and quality. Often with big screen analog broadcasts, the picture is severely degraded because of the resolution lines. |
