Today's Best Buy TV Options Always Include A Wide Array Of Sizes And Types

By Lee Larossier


When television was first introduced to the public, the cabinet was bigger than the screen itself. Color TV resulted in an even larger cabinet. Currently, the casing of a best buy TV is most often very thin and lightweight. These can easily be hung on a wall and viewed at any height.

Most people planning to purchase a new TV want at least a twenty-inch screen. Flat-screen televisions can be as large as sixty inches. Each screen is measured on the diagonal as computer screens are measured. Homeowners now can afford home theater systems because of the large screen sizes available. They put in leather recliners with cup holders and serve bowls of popcorn to their friends and family. Guests gather together to watch a movie on the large display screen.

The plasma display panel is usually more than thirty-inches in size. The term plasma refers to small cells that are electrically charged and contain ionized gas. A cell of this type is a tiny chamber that is a fluorescent lamp. Plasma has one important disadvantage. It is more glaring to watch.

The LED is a flat panel display LCD. It uses LED backlighting rather than LCD fluorescent back-lighting. In advertising the terms are sometimes interchangeable. The three types of LED are white-edge, which uses a diffusion panel. There are also those with an array of LEDS and those that have the dimming controlled individually.

Many consider a TV that can deliver programs in high-definition to be very desirable. The picture has clarity and that makes watching a program in HD preferable because it is more realistic. Not all programs are produced in high-definition, although technology is heading in that direction.

The LCD is another screen offered for sale at best buy TV. LCD stands for liquid-crystal display. The technology provides thinner and lighter screens that can be mounted on the wall using a special device. Usually a professional technician is required to guarantee the safety of such an installation. These screens are now the biggest sellers of all the available types.
